Elaborate on your work experience as a math tutor Personal Statement

Elaborate on your work experience as a math tutor - Personal Statement Example I remember the time when I tutored a 9th grade girl who always had bad experiences with Math. As a tutor, I learned that aside from helping students deal with Math, it is essential that a tutor should also give encouragement. Based from experience, this student was afraid of Math because she was not confident of her answers and that she feared making mistakes. I encouraged this student by encouraging her to exert some efforts to understand the problem and take one small step at a time. By boosting her confidence and telling her that she could do it, I actually changed her self-concept from being pessimistic to an optimistic in terms of developing a ‘can do’ attitude, especially in solving math problems. I have been tutoring for four years and I teach 2nd grade through PreCalculus. I would like to continue being a Math tutor because I want to help children in need. I would like also to help other people who want to succeed in life. My ambitions of why I would still remain as a Math tutor are not to make money but to pursue higher education to expand the pool of people I could help and thereby be a contributing member of the academe and community for

Landscape Essay Example | Topics and Well Written Essays - 1250 words

Landscape - Essay Example This island also inhabits grasslands and mountainous areas as well as plateaus, which spread throughout the country. Its fame also comes from the Blue-Mountains appearing from the southeastern end of the country. The blue haze name emanates from oil droplets trickling from the eucalyptus trees. The many beautiful beaches cap the geographical uniqueness of this island. In Australia, indeed, there are many things to be curious about; it is truly a unique country as this largely feature as the monuments and vernacular landscape traits of the country. Origin of the landscape In the 18th century, Captain Cook discovered the island of Australia 1770. This is where the originality of this country lies even though there might be other chances that another voyage ship might have graced the country. This emanates from the possibility that a Portuguese first sighted the country. The Dutch are also known to have explored the coastal region of the country by the 1640s. It therefore earns the acco lades as the lowest, flattest, and oldest continental landmass on Earth. It had the relatively stable geological history. Its formation involves forces such as tectonic uplift of the mountains ranges or clashes between tectonic plates in early landscape history. This occurred still when Australia was part of Gondwana. T he highest peak of Australia, which resulted due to the tectonic forces, was about 7,310 ft, which is comparatively low in assessment to the premier mountains in other continents (Duncan, Nuala, and Richard 92). The current shape of the continent has its shape because of the erosion, which has heavily weathered Australia’s surface area. The country now sits in the middle of the tectonic plate hence no active volcanism. As a result, the first European settlement in the country was in January 1788. It is this time, after the discovery of the Island. The first fleet sailed into Botany Bay under the command of Command Arthur Philip, establishing Australia first as a penal colony by the 1640s. Ethnic makeup of its people Australia’s original inhabitants, the Aborigines, settled there between the ages of 42,000 and 48,000 years ago. These inhabitants arrived via the land bridge and short sea crossing from South East Asia. At these ages, the sea water levels were relatively low as compared to the soaring heights in today’s Australia. The original inhabitants were soon out-numbered by the settlers (Duncan, Nuala, and Richard 88). The story of migration, like any other country in the era of colonization, brought another sect of its population. Nevertheless, the Australian history of its ethnic population does not stop there. Immigrants keep arriving in this country. This continuous flow of immigrants makes its history steeped with the settlers. Their arrival has had an effect on the land and its people. The Role of religion in forming places In the 21st century, religion in Australia purely comes as Christianity. 61.14 % of the Aust ralian population predisposes itself to Christianity as per the census of 2011. In respect to history, the current percentage is far much higher and the religious landscape is diversifying. This comes along with the multicultural immigration as 22.3% of people with no population. With 8.55% of the population not able to incline to a certain religion, the remaining population consists of a diverse group of Buddhist at 2.46%, Islamic at 2.21%, Hindu at 1.28%, Jewish at 0.45% and Sikh at 0.3% of the entire

Emerging markets Essay Example | Topics and Well Written Essays - 1000 words

Emerging markets - Essay Example Emerging markets are becoming the fastest drivers of global development. These markets are expected to grow twice or thrice the number of developed countries like the United States. The public investor continues to underweight these developing markets in their collections. Corporate profits seem to grow rapidly when there is a higher economic growth. One of the reasons why developed markets like the U.S have been ranked high is because of the development of markets outside the country. Some nations are borrowing a leaf from the U.S and are performing well as emerging markets. They include Brazil, Indonesia, Chile, Israel, Egypt, Turkey, Pakistan, Russia, Peru, and Korea. In this context, Turkey and Peru are the markets discussed, putting in mind that some of the factors that have contributed to their emergence are: The significance of trade, the role of the government, investments and savings, and education among others (Larrain, Helmut &Maltzan 67). Factors that have allowed Turkey to move up the development ladder Importance of investments and savings Historically, Turkey has been dependent on developed markets for a huge portion of its investments and savings. However, the country is now focusing to engage in more business with other regions of the world, with the Middle East, Asia, and Africa included. It is this shift in focus that is accelerating the growth and investment of Turkey. In addition to this, Turkey has in recent years overcome a sequence of economic and political challenges and is now benefiting from a period of solid and stable economic growth, which enables it to grow at least five percent yearly. Its world class characteristics include the strategic position at the crossroads of the Middle East, Europe, and Asia. To add on these strategic positions, the huge size of its domestic markets also attracts some investors, who remain confident about the country’s features. The goods market below shows relationship between the savings and in vestments of Turkey at equilibrium. The role of the government, its policies and programs The structural transformation of Turkey was generated by political stability and economic reform. First, the newly implemented FDI frame law by the government marks the foremost instalment of this economic reform to alter the investment setting in the country and make it attract global investors. The FDI frame law ensured equal treatment to all investors regardless of the initial authorization request to move dividends freely, to be guarded against expropriation, to get access to real estate, and to hire emigrants. Turkey reduced corporate tax from approximately 33% to 20% for each company. The reason for doing these was to make Turkey one of the leading liberal nations worldwide in terms of the investment environment and for FDI framework. The consequence of this transformation have been promising and significant, since the country started to grow at a faster rate after 2001 and it now has the utmost industrial power as well as the one of the leading free-market economies. The economic programs were founded on a powerful macroeconomic policy framework. Some of the broad-ranging structural government reforms are a key renovation of the banking system. A liberal foreign investment government, a better investment atmosphere, and privatization are the major pillars of government reform. The economic programs joined with supervisory and regulatory reforms improved the Turkish economy’s toughness to shocks. Consequently, Turkey emerged from the international crisis to be among the globe’s fastest-growing economies (Aguiar, & Gopinath 23). Educational level The availability and access of highly learned personnel is a position-specific element that has made Turkey emerge economically. High educated person are highly required by businesses that invest in technological businesses and have assets in skills like the capabilities to develop intangible or differentiated products. The presence of elites in interaction with labour

Global Economics Essay Example | Topics and Well Written Essays - 1000 words - 2

Global Economics - Essay Example This paper talks about two big concepts of the global economics which are Inflation and Economy of Scales. There are various reasons which may lead to increase in costs. The first reason includes the rising costs of imported raw materials possibly caused by inflation in nations that heavily rely on exports of these products. Also, a fall in value of a country’s currency in the foreign exchange markets increases the price of imported inputs of that country. The second is the rising costs of labor; this is caused by an increase in wages which exceed and enhancement in productivity. Labor intensive firms are largely affected by this cause. Firms may not be able to absorb higher wage expenditures; thus, they pass the costs to customers. As a result, the wage inflation increases the price inflation. Thirdly, the imposition of higher indirect taxes by the government. An example is the increase in the excise duty rate, VAT, standard rate or fuel duties. These taxes are charged on manufacturers who, depending on the supply for their commodities and price elasticity of demand, may decide to pass on the tax burden onto consumers. In marketing economies of scale, a bigger firm may spread its marketing and advertising budget over a great output. It may also buy its raw materials in bulk at discounted prices. In financial economies of scale, financial markets frequently consider bigger firms to be more creditworthy than smaller firms. This enables these firms to access credit facilities at favorable rates.

Discuss one or more theories of Moral Understanding and evaluate its conclusions Essay Example for Free

Discuss one or more theories of Moral Understanding and evaluate its conclusions Essay The term morality, according to Shaffer (1993) means â€Å"a set of principles or ideals that help the individual to distinguish right from wrong and to act on this distinction. Morality is important to society, as it would not function effectively unless there is some agreement of what is right and wrong. There are many underlying processes and environmental factors, which limit or promote social, cognitive and moral development in children. In modern society, television could be considered to be one of the major influences on a child’s moral development. There are three approaches to moral development; the cognitive approach, the psychodynamic approach and the social learning theory. The Cognitive-Developmental approach of Piaget and Kohlberg studies how children become more able to reason morally and make moral judgements, whereas the Freud’s psychodynamic approach is more concerned with the development of the conscience and moral feelings such as guilt and anxiety. The social learning theory of Bandura and Mischel investigates the development of moral behaviour and how role models in the family, society and the media, influence it. The theory I am going to discuss is Piaget’s Cognitive-Developmental Approach. His theory of moral development is concerned with how the child’s moral knowledge and understanding change with age. Piaget saw morality as any system of rules, which governs interaction between people. The methods of investigation he used to develop his theories were, he looked at the way children imposed rules in their games. He used games to study the development of children’s moral development as he thought that by studying rules in the context of a game, he could study the child’s spontaneous though directly. He also, assessed changes in the child’s moral judgements by telling hypothetical stories about children who lied, stole or broke something. When using hypothetical stories, Piaget was generally more interested in the reasons why the children give the answers they did and not particularly the answers. Piaget identifies stages of moral development just as he identified stages with cognitive development. His theories of the way children think and their moral reasoning goes through a series of stages, as they are adapting to the world, these are also known as the processes of accommodation and assimilation. He believed that as children’s reasoning about the world changes when they grow older and gain more experience, so does their reasoning about morality. Their ability to think about the world in more complex ways is what causes them to move on from one stage to the next. This is known as cognitive development. Piaget stated that infants don’t understand much about morality until they are about three or four years of age. Their development divides into two main stages after infancy. His stages of moral development are: Pre Moral Stage (up to three or four years) Children don’t understand about rules, and so they don’t make moral judgements Stage of Heteronomous Morality (aged three – six years) Children at this stage think rules are absolute and unchangeable, and the goodness and badness of an action is judged largely on the basis of its consequences rather than by taking intent into account. Stage of Autonomous Morality (from around six or seven) Children at this stage now see rules as more changeable and intentions are taken into account. Children also start to believe that it is possible to break rules and get away with it, whereas earlier they tended to think they will always be found out and possibly punished. Researchers from Europe and America have tested some of Piaget’s theories and have concluded that distinct stages of development do seem to exist however, other research found that children do not see all rules as being equally important as Piaget thought they did. Heteronomous Morality, also known as moral realism, means when the child is subject to another’s laws or rules. Children think that rules must be obeyed no matter what the circumstances. A child at this stage will think that rules are only made by authority figures, such as, parents and teachers. Two other features that are displayed in moral reasoning at this stage are, first they expect bad behaviour to be punished in some way, they believe that the punishment should be expiatory – the wrongdoer must make amends for the crime by paying with some kind of suffering. They have the view that the amount of punishment should match the badness of the behaviour. Secondly, if the bad behaviour goes undetected then the child believes in immanent justice – where any misfortune occurring after the bad behaviour can be seen as a punishment. For example, if a child tells a lie and gets away with it, then later trips and falls, the younger child could consider this as a punishment. In general, they believe punishment should be fair and that wrongdoing will always be punished in some way. Autonomous Morality, which means when the child is subject to one’s own laws and rules. It involves moral relativism whereby the child comes to realise that rules evolve from social relationships. Due to the child ‘decentring’ and their developed ability to think more flexibly about moral issues, they have began to realise it is important to take other people’s opinions into account. At this stage a child will have developed the understanding that sometimes rules of morality can be broken in certain reasonable circumstances. They believe in reciprocal punishment, whereby the punishment should fit the crime. For example, if a child takes another child’s sweets, the first child should be deprived of their sweets or should make it up to the victim in some other way. This is known as the principle of reciprocity. Children will also have learnt at this stage that wrongdoers often avoid punishment, diminishing any belief in immanent justice. They see punishment as a method of making the offender understand the nature of the crime and that punishment is also a deterrent. The move from heteronomous morality to autonomous morality is influenced by two factors. Children around the age of seven begin to move on from the pre operational stage of an illogical and an egocentric way of thinking to more logical and flexible way of thinking, in the operational stage. Their growing awareness that other people have different views allows them to develop more mature moral reasoning. However, moral development lags at least one to two years behind cognitive development because the whole process depends on the cognitive changes occurring first. Kohlberg expanded Piagets theory to form a theory that also explained the development of moral reasoning. While Piaget described a two-stage process of moral development, Kohlberg’s theory outlined six stages within three different levels. Kohlberg extended Piaget’s theory, proposing that moral development is a continual process that occurs throughout the lifespan. A study by Colby et al (1983) criticised Piaget’s assumption that children of ten and eleven years old had reached an adult level of moral reasoning. Piaget was always focusing on what an average child was capable of achieving so he neglected the idea of great variations between the individual child’s ways of thinking. In general, Piaget’s cognitive theory has been criticised for the methods of investigation not being as precise as they could have been. Methods he used were seen as complicated, leading critics to think he under estimated younger children’s capabilities of what they could and could not do. This was because later research went on to conclude that children could actually take other motives into consideration, when they understood what motives were involved. Despite criticism, Piaget’s work is still regarded as a revolutionary step forward in the way we understand how children think. It has led to a much more realistic ways of understanding children’s moral development. Many attempts to test Piaget’s theories from researchers around the world have resulted in acceptance that some of his views and methods do appear to exist.

Malaria: Causes, Effects and Cures

Malaria: Causes, Effects and Cures Solving a Biological Problem Summary The chapter is about the methodology that is involved in exploring some understanding toward solving a biological problem while doing research in quest. With citation of example of malaria as a problem along with historical stage involved towards gradual understanding related to its causes leading to the findings to its cure and preventions, an attempt was made to present the approach that has been involved in addressing the scientific issues in past. A practical approach that is possible to conduct practically at school level to get the students introduced with research at elementary level and built up some interest in students has been presented in the following chapter. Mathematical and statistical tools that are needed in research have been introduced to analyze the data obtained by using research methodology (hypothetical) to arrive on conclusions about certain aspects of the issues related to malaria to accept, discard or modify the hypothesis on a scientific query. Introduction The human being started putting efforts to explore the world around him right from very beginning. The history is full of examples that show that early human being somehow recorded their opinion about different thing. With passage of time, human beings learnt to evaluate the correctness of their thoughts and opinion on any scientific issue, by setting some experiments, drawing conclusion (hypothesis) based on results, verification of hypothesis by other experiments and reporting it. Research methodology is latest approach involving these procedures to address a scientific problem. Steps involved in Biological Research Procedure Identification of a problem Sufferings of mankind that includes diseases, scarcity of food shelter, utilities etc or related matters are the existing problems from biological origin. To initiate research in an area a problem in a particular area is identified. There can be a wide range of problems e.g. an approach to find a cure for newly emerging disease, find a more effective drug for a curable disease, increase the shelf life of a product etc. Generation of hypothesis Available understanding on an issue that is published in scientific journals is used to draw logical opinion, hypothesis, underlying the biological processes and indicate possibilities that can lead to the management of the problem. There are often more than one hypothesis available for a given scientific query. Usually one hypothesis is being testified by given experiments. (a) Shelf life of chadder cheese increases with increase in number of yeast cells present into it. (b) Quality of spinach deteriorates with increase in rate of transpiration. (c) The rate of decrease in microbial population in a food sample in response of heat treatment at 600C is inversely proportional to its total organic content. Laboratory safety Procedures Every type of biological experimentation should comply with necessary safety procedures that ensures the safety of professionals involved in conducting the experiments and other people. That includes use of special clothing e.g. coats, gloves head cover spectacles etc. All the biological material is carried or grown in specially designed containers that ensure no risk for leakage that can be hazards for other people who can come in contact. All the biological material is heated at 121oC under pressure at 15 psi to kill all type of cells before discarding it whereas chemical agents are discarded as mentioned in safety manuals. Experiment Design Experimentation is a practical approach for investigation a scientific query leading to generation of observations called data. A same question can be investigated by using different experimental approaches. The selection of an experimental design mainly depends upon time required, extent of precision, availability of resources etc. Each experiment design has got some limitations and it is important to ensure that the selected experiment design can optimize for investigating the required scientific query. Each experiment is design by usually changing a variable. In order to test a given hypothesis, experiments are set, usually in triplicate and experiments are repeated at least three times to ensure reproducibility of the data. To avoid adding error in the data it is important to set negative and positive control for a given experiment. Positive control has an ingredient instead of ingredient to be test that should positive result when is added in the reagents and processed as per standard method of experiment in given conditions. On other hand Negative control is set same as positive control but has water or other solvent added instead of reagent to be tested. It is very important that selection of sample that is used in the experiment should be random. It is important to ensure that all the experiments should be done at the same conditions. All those factors that can contribute to add errors should be taken care of. Data Collection and analysis Observations can be collected after completion of experiments or while they are in progress depending on nature of experiments. The data is not always a integral values but can be visual observations that can be recorded by photography. The data is usually recorded with appropriate units in tabular form. This is known as raw data. Every data has some error added into it. Mathematic and statistics an integral part of Biological Analysis The observations that are collected as numerical value after experiments comprise raw data. Mathematical or statistical methods are used to minimize the effect of errors present into it the raw data. The most widely and commonly statistical method that is used to decrease error in data is finding an average in any given readings. Beside that mathematical or statistical tools are used to deduce a logical ground based on numerical value to support, modify or discard any scientific opinion (hypothesis) that is built up on earlier reported scientific findings Use of ratio proportion and percentage Data is analyzed by using mathematical or statistical tools, most commonly that are used include ratio and percentage, for finding an effect of changing a variable on other parameters in a given set of condition. If a numerical variable ‘a’ represents intensity of a biological event that needs to be compared with intensity of another similar event represented by numerical variable ‘b’ then ratios are taken out Ratio between intensity of two biological events = a (equation 1) b In order to represent this comparison on scale of 100, percentage of ratio between variables are taken out The general formula for percentage is given as below %= Ratio between two numerical variable x100(equation 2) Substitute equation 1 in general formula of percentage as shown by equation 2 Percent % (ratio between intensity of two biological events) ={ a }x 100 (eq 3) b Usually biological data can comprise of in a range of very small value to very large and hence it is important to convert it on Log10. The general formula for expressing any numerical variable is shown by equation 4 as follow Number(N) on Log 10 scale= Log10(N) (equation 4) Substitute equation 3 into equation 4 Log 10(ratio between intensity of two biological events) =Log10 { a x 100}(eq 5) b Technical limitation associated with use of Log10 scale While expressing any data on Log10 the difficulty arises when it is needed to express integral 0 on Log10 scale (Log10(0)=infinity). In order to cope with this difficulty 1 or any fraction of number that falls within permissible limit of error (10 scale. In later stages the data can easily be plotted on any type of graphs as discussed in later part of this chapter. Significance of error in decision making and predictions on biological data Every data collected has certain extent of error present into it depending upon experimentation design, procedures and method of taking observations. This error needs to be evaluated before using the data for testing any hypothesis, decision making or predictions. It is defined as tentative variation on negative and positive scale in a set of observations from actual value. The actual numerical value of a biological effect is (B). An experiment was done to note this biological effect. The experiment was repeated N times e.g. (N1 N2 N3 †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Nt) to showing observations B as (B1 B2 B3†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.Bt) respectively. The first stage in calculation the error is to find an average The general formula for Average is Average = sum of numerical values of individual observation eq 6 Number of times the observation was taken Substitute the values in equation 6 Average ={B1+ B2+†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.Bt} eq 7 {Nt} Sum of values of observations ={B1+ B2+†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.Bt}is shown by S{B} No of times the experiment was repeated {Nt} ={N} Substitute the value in equations in equation 7 Average= S{B} equation 8 {N} Lets value of Average be represented by X Substitute in equation 7 Average = X Second stage is to find the difference between each numerical value of observation and Average = B1-X, B2-XBt-X, Third stage is to square each of the difference =B1-X)2,(B2-X)2, (B3-X)2(Bt-X)2 Fourth stage is to add the square of differences =(B1-X)2+(B2-X)2+(Bt-X)2 Fifth stage is to divide square sum of difference of average of individual numerical variable with number of observations e.g N =S(B1-X)2,( B2-X)2,†¦..(Bt-X)2 N Standard deviation or Error is obtained by taking square root of the quotient obtained by dividing the square sum of difference between the average and the individual numerical variable with number of observations. =√S(B1-X)2,( B2-X)2,†¦..(Bt-X)2 N It is an integral value that is expressed, as on negative as well as positive scale e.g if error calculated is 3 then it would be +3 as well as –3. It represents a range within which actual value may lie. In olden days, such calculations were done with the help of calculator but now same work can be done more easily by using different software e.g. excel with computer as a tool. It is often very different to understand the effect underlying in any biological data by merely looking at numerical values. The different types of graphs are used for visual presentation of effect by trends available in data The most commonly types of graphs that are used for the presentation of data are given in figure 2.The same data for different sample e.g. A, B, C is presented on percentage scale by using horizontal and vertical bars whereas error is shown by error bars .Another set of data for sample D, E, F was presented by line graph. Data analysis to decide the status of hypothesis After the mathematical and statistical treatment of raw data a logical ground built up by comparing certain numerical values or more often represented on graphs to accept, modify or reject any hypothesis. In order to test the hypothesis â€Å"The rate of decrease in microbial population in a food sample in response of heat treatment at 600C is inversely proportional to its total organic, 100 cells of Saccharomyces cerevisiae were inoculated in same volume in mediums with concentration as X, 3X and 70X respectively to make final concentration of each medium as 100 cells/ml.(Sample D contains 3X concentration medium, Sample E contains X concentration and Sample F contains 70X concentration). The medium were kept at 600C for 1104hours and cells were assayed for viability after 10 hrs, 100, hours, 1000hrs and 10000 hrs respectively. The viability being dependent value was plotted on a graph Y axis against the time in hours after expressing the value on Log 10 scale. Different data points taken on the graph are sufficiently scattered and can not be joined by a straight line accommodating all the point on it. The trend line can be drawn manually by accommodating maximum number of points and leaving as many point above the line as many are there below that line. Such a manually drawn line can not be used for any type of scientific predictions. Otherwise highly precise trend line for a given data can be drawn as explained in section given in the end of the chapter that can be used for making decisions on a given hypothesis and for making predictions. The error bars extending on positive as well as negative scale in same magnitude of Y scale is plotted against each observation. The observation that were taken in this experiment are shown as graphs in Figure 2 e.g. Sample D, E and F were presented by using line graphs on Log 10 scale. The trend lines are introduced to show the type of dependency of one parameter on another. As already discussed earlier the biological data is often presented on Log 10 scale to observe the effects in broader prospective and ignore the slight changes especially when study is made on larger populations of samples e.g. cells with a wide range of variations. The data show that sample D and E has got similar trend (with an increase in variable on X axis, there is a decrease on Y axis variable, Y axis is dependent on x axis and is inversely proportional to it) whereas in sample F, Y variable is independent of X variable as no change in Y variable is observed with an increase in X variable and this is evident by a straight trend line. The conclusion drawn as evident by three graphs that number of viable yeast cells were found to decrease with passage of time when concentration of organic content in medium was X in sample E or 3X in sample D that is represented by a slopes in respective graphs. But this effect was found to be lost when organic concentration was raised to 70X in sample F and that is. This experiment supports the hypothesis â€Å" The rate of decrease in microbial population in a food sample in response of heat treatment at 600C is inversely proportional to its total organic content†. If reported literature indicate some other type of experiments done to check the same hypothesis then results are compared and reason of the variations if there are any are discussed with scientific reference and is reported in a scientific journal. Research Methodology Theory accepted Modification in hypothesis Publication in scientific Journals Discarding above hypothesis Supporting above hypothesis Results interpretation Different Hypotheses Data analysis Data collection Experimental design for a given hypothesis Literature reported in related area Identification of Biological Problem Interpretation of data The data that is obtained is interpreted to draw scientific conclusions. The reported literature is used to give explanation of the conclusion drawn. In the light of conclusion drawn either the hypothesis is accepted, rejected or is modified. If the hypothesis is proven correct with experiments, then it is known as a theory. Scientific articles based on proven hypothesis e.g. theory, disapproved or modified hypothesis are written by scientist involved in research and are sent for publication in scientific journals. Biological Problem as an example A school teacher planned an excursion for students and took paramedic staff equipped with sample collection facility to country side area to study the prevalence of any non contiguous disease in human beings and animals. Malaria is an example of non contiguous disease that is spread only by infected female mosquito is malaria and is a matter of great concern. As reported in newspapers and other literature there was a population of 100,000 people living with minimal facilities of life that on a huge natural water reservoir for drinking water. Recent heavy rain resulted in collection of water of stagnant water and much of this water in later stage drained in reservoir. The students prepared a report explaining how did they use biological methodology to study this case. a) Identification of problem Prevalence of certain incidences of disease symptoms similar to malaria in a given locality was identified as a biological problem. Students wrote the following note after referring the literature about malaria to get basic information about disease. Please refer the picture given below and the literature cited in later part of this chapter. From Mala aria ( bad air) to Malaria-over a period of time Malaria has been a matter of concerns since very beginning. Understanding about malaria has changed over a period of time. Initially it was considered to be caused by some supernatural power. Supported with the findings of higher incidences near the marshy area, malaria was thought to be caused by bad air that is found near marshy areas. With the emergence of germ theory malaria by Louis Pasteur (1852-1895) was thought to be caused by any bacteria. It is strongly believed until Charles Louis Alphonse Laveron (1845-1922) during microscopy of Blood from infected patients observed causative agent of malaria in 1880 and later on reported it to Academy of Medicine in Paris. Albert Freeman Africanus King (1841-1940) who was associated with George Washington University on basis of supporting reports presented the idea that mosquitoes are the mean of transmission of malaria (vector) and discarded the opinion that bad air in marshy area has any role in causing malaria. On basis of his data he suggested that proper netting can help to control the incidences of malaria in Washington. Ronald Ross (1857-1932) was a physician, who studied the life cycle of malarial parasite in mosquites e.g (different stages of parasite infection with a change in morphology) and its transfer to human beings and birds. In 1898 Giovanni Battista Grassi (1854-1925) on basis of understanding about malaria obtained by published literature set an experiment to infect a person who never had malaria (with his permission) in an area of Rome where there was not any case of malaria reported and mosquitoes were not found by exposing the person with Anopheles clavigar for ten night and later on patient developed the symptoms. On basis of his experiment he proved that malaria is spread by mosquitoes in human beings that carries the causative agent Plasmodium. The complete cycle of P. falciparum was observed by Grassi Bignami and Bastianelli in 1899 and the work has been published by Grassi in 1900. The life cycle of Plasmodium has three reproduction stages with different morphologies (shapes). The mosquitoes inject sporozoites in human being s skin that through blood goes to liver where they multiply and change into Merozoites.The second cycle of multiplication does into RBC. Some of the meroziotes after passing through reproductive cycle in RBC converts into gametocytes (male and female gemates) and enters in gut of mosquitoes when they suck blood from an infected human being where they undergo sexual reproduction to zygote which later on converts Oocyst. Oocyste after under going asexual reproduction burst to release newly formed sporozoites that enters in salivary gland of mosquitoes At the site students made a survey of that area and noted the initial observation with the help of photography. They found that not only human being but also the birds are affected by the disease Initial Findings They found that the reservoir (a) was associated with dark places where high populations of mosquitoes can be seen (b).Beside that a few sick birds were also found resting on ground. Diseased patients report to an increase in high fever with shivering that stays for some times and then fever become low or even normal with sweating or even without it. These symptoms are repeated with intervals and patient feels weakness. Initial findings support that the disease is malaria. b) On the basis of their initial findings the following hypothesis was built up. The disease may be Malaria and is caused by Plasmodium Experimentation Plasmodium infect the red blood cells. In order to established that diseased people are suffering from malaria at least 63 patients having disease were bled to collect blood samples. This type of sample that is under study is called as test sample. Blood were taken from at least 50 healthy who do not have any symptoms of disease. Since these people do not have any symptoms of disease it is very likely that Plasmodium may never be detected in their blood. Such a sample that is known to give a negative test is a called a negative control The blood and water samples were collected in collection tubes specially designed for this purpose. The fixed slides of infected Red Blood Cell (RBC) were purchased from the market and was taken as positive control. (a)The sample was not only collected from human beings but also from the diseased animals as well. That the blood of each sample was spread on a glass slide, fixed and stained with Giemsia and was observed under microscope. (b)Beside that the blood samples from infected people were inoculated (added) in RPMI-1640 medium (name of medium used for the growth of Plasmodium that also contain RBC) present in bottle and were incubated to grow causative agent of the disease under laboratory conditions. The sample from these bottles were observed under microscope for presence of Plasmodium after 72 hours of incubation. Furthermore, the surface water from stagnant regions of reservoir was collected in a container and was assayed for presence of larvae of mosquitoes with help of magnifying glass. Laboratory Safety Procedure All the containers having biological material was heated at 1210 C at 15 psi for 15 minutes to kill every type of living cells before discarding them. The chemical agents were discarded as described in their respective safety manuals Result Microscopy results show that the Red Blood Cell of diseased people were found to be infected with Plasmodium. The causative agent of the disease was successfully found to grow in the medium that supports the growth of Plasmodium (Figure 3) and that was confirmed by microscopy e.g Plasmodium were found in the sample from medium under microscope and slides observed were found similar as shown in Figure 1 and Figure 2 Plasmodium Figure 7 The blood sample after mixing with other reagent (as shown with white arrow indicating towards a tube) is then inoculated into the bottle ( as shown in picture) ( source Nature Protocols courtesy to Nature Publishing Group) The surface water samples that was taken from the stagnant water collected near water reservoir were found of have mosquitoes larvae in large number as is shown in Figure 4. Conclusion The results that includes, presence of large number of mosquitoes larvae near the site of outbreak, Plasmodium was found in the infected blood of diseased people, that was successfully grown in the medium and conditions specific confirm that the outbreak is of malaria that was caused by Plasmodium. Skill development to solve a Biological Problem Report A report comprising the incidences of malaria during the years 2002, 2003 and 2004, in three different cities was published in a newspaper. The patient were treated by using drug A and attempt to kill mosquitoes were made by spraying B into environment and adding in water collection. Out of these report related to three cities is given below. In Karachi 530 malarial cases were reported in year of 2002, 534760 in 2003 and 12345668 in 2004 respectively. The mortality reported in these years were 98 in 2002, 120001 in 2003 and 5408889 in 2004.The rain fall recorded in Karachi for year 2002 is 50mm, 2003 is 100 mm and 10,000 mm in 2004.The drug resistance was found in 12 cases in 2002, 60009 cases in 2003 and 9900099 cases in 2004. In 2002, 134 malarial cases were reported in Faisalabad where as in 2003 and 2004 the reported numbers were 1237 and 1379 respectively. The mortality reported in years 2002, 2003 and 2004 were 10, 99, 115 respectively. The annual rainfall reported in these years were 12 mm in 2002, 58 mm in 2003 and 89 mm in 2004.The antimalarial drug resistance was found to be in 2 cases in 2002 , 79 cases in 2003 and 91 cases in 2004. In a similar study that was conducted in Gilgit during these three years, it was found that malaria affected 325 people in 2002, 135 people in 2003 and 350 people in 2004.There were 10 people reported to be died of malarial disease in 2002, 8 people in 2003 and 17 people in 2004. The annual rainfall reported in these years were 130, 120, 105 mm in 2002, 2003 and 2004 respectively. The resistance against anti malarial drug found in 2002, 2003 and 2004 were 9, 4, 9 respectively. Source ( It is an imaginary situation given with data to help student develop research skills) Research Methodology Step 1 Identification of problem from published literature After reading the above mentioned findings, management of heavy occurrence of malarial disease has been identified as a problem. Step 2 literature search for generating the hypothesis taking malaria as a test case Malaria is a very common infectious disease that is commonly associated with poverty. It is caused by protozoan parasites Plasmodium species that is transferred to human being blood circulation system by the vector Anopheles mosquito’s bite(1). Literature show that malarial outbreaks can be related with rainfall in that area (2). Malaria is more common in urban area than in cities. However in Africa it is present in both rural and urban areas (3,4)No literature is available about the relation of malarial incidence with location of the place with height above sea level. The occurrence of malarial outbreak can be related with presence of stagnant water that can support the mosquito survival in populations. Heavy use of anti-malarial drugs and mosquito cidal sprays is reported to produce resistance in the protozoa against commonly used drugs (5). 1) Cox F (2002). History of Human parasitology.

Philosophy of Education Essay -- Education Teacher

My beliefs and values about early childhood education is based upon understanding that all children are unique individuals who need a caring, nurturing, and secure environment in which to grow and develop socially, emotionally, cognitively, and physically. Children under the age of three are in critical stages of development, it is my belief that a quality child care environment will have a positive impact on a child’s development and make a significant difference in the life of a child and his or her family. My philosophy of early childhood education and the elements I believe are necessary in developing a developmentally appropriate child care environment is rooted in my views and beliefs about experimentalism, progressivism, multiculturalism, and the influence of philosophers such as Dewey, Piaget, Montessori, and Vygotsky. Furthermore, I believe young children will thrive and grow in developmentally appropriate child care programs that possess the following elements: (1 ) teachers who see themselves as intentional, responsive and respectful facilitators of learning, (2) the ability to build a community of learners, (3) implement an effective curriculum that allow children to explore their natural curiosity about the world. Although there are many educational philosophies, the two that most inspire my belief about early childhood education are experimentalism and progressivism. John Dewey’s experimentalism â€Å"saw thinking and doing as a unified flow of ongoing experience† (Gutek, 2009, p. 81). I view the world as an ever-changing place; therefore, I believe in teaching children to solve problems by examining and making discovers based on real life experiences. In combination with my experimentalist view, I value aspects of p... ...hildhood teachers, I will continue to encourage them to grow as professionals to ensure they are providing a caring, nurturing, and secure environment that promotes growth and development in young children. My philosophy of early childhood education is reminds me of why I do the work that I do. I remember that children are active, curious individuals that will grow up to be active, curious, and hopefully productive members of society. It all begins at birth.
