I Want to Make a Difference :: College Admissions Essays

I Want to Make a Difference When I was in the third grade I came home from school and told my mother I wanted to be a teacher. When she asked why, I replied, â€Å"because I want to be just like my teacher.† To this day I haven’t changed my mind. I was fortunate enough to have been blessed with wonderful teachers in my elementary school years. If it wasn’t for them I might not have the desire to become an educator. I want to have this kind of impact on my students. I want to the teacher who makes the difference. I work at a day-care and absolutely love being with the children. I have taught many children to spell and write their names, learn the alphabet and colors, and tie their shoes. After helping a young child accomplish a â€Å"difficult† task and seeing how excited he is, makes me feel great. When I look at myself as being a teacher, I see myself practicing authoritarianism. I will know my content and teach it will. I will value my students as individuals, not as a group. My classroom will be run on a bell-to-bell schedule. There will be a meaningful assignment on the board for the students to do as they enter the classroom. When students are learning, the appropriate seating is necessary. I will assign my students seats, changing them often. For lecture, the students will be seated in rows and columns, in a circle for class activities, and placed in groups for group work. The classroom rules will be very distinct. The rules, along with the consequences when is one is broken, will be posted in a very visible place in the classroom. There are two rules in which I will insist upon in the classroom. They are to treat others the way you want to be treated and follow all school rules. My students will help me compose the other 3-5 classroom rules. Misbehaviors are always problems in the classroom, however I hope to have few in mine. If I see a problem starting, I will do my best to stop it before it continues.

Article Critique Essay

The thought that peer exclusion is correlated with children’s classroom achievements and adjustment has been hypothesized since the 1930’s. Much research and empirical evidence for such hypotheses have since been collected, and seem to agree with the premise of the correlation. Peer acceptance is the main measurement of this study. In contrast with other types of peer relationships, peer group acceptance, or rejection, is strongly connected with academic readiness and achievement. This article focuses on peer sentiments and its effect on children’s adjustment. It differs from past studies in that its approach is to measure non-observable feelings about classmates, rather than only the observable interactions. The article begins by outlining past research, and developing a premise for the study from those previous studies. The main study that this research builds upon is that of a 2001 study by Eric S. Buhs and Gary W. Ladd, who also conduct this study along with Sarah L. Herald. The premise of the study, based on the 2001 study, is that once classmates express negative feelings and actions upon a peer, those feelings and actions act as a visible marker for further rejection by the larger peer group, and the rejected child as well; as a result, the rejected peers are flagged by their peers, and are left out of classroom interactions, and as a consequence, the rejected child’s learning is impacted ultimately leading to lower levels of achievement (Buhs, Ladd, and Herald, 2006, p. 2). The prior 2001 study found that â€Å"early peer rejection was negatively related to later achievement and that this association was partially mediated through peer maltreatment and declining classroom participation, respectively† (Buhs et al. , 2006, p. 2). The authors developed a hypothesis that built upon their previous study. Their hypothesis was stated as, â€Å"it was hypothesized that prolonged peer maltreatment increases the probability that children will disengage from classrooms (or the school context) and that increasing disengagement impairs children’s achievement. Thus, it was predicted that longer rather than shorter histories of peer maltreatment, after controlling for contemporary exclusion or abuse, would mediate the link between early peer rejection and later classroom disengagement† (Buhs et al. , 2006, p. 3). The authors further state that their purpose for conducting this study was to bridge the gap between the limitations of the previous study (it was only a one year study that attempted to predict students future outcomes) by conducting a more comprehensive longitudinal study over a six year period (kindergarten through fifth grade). Methodology The research study constructed six variables to measure the children with. They include, peer group acceptance/rejection, peer exclusion, peer abuse, classroom participation, school avoidance, and achievement. Peer group acceptance/rejection was conceptualized to mean â€Å"the extent to which individuals were liked/ disliked by classroom peers,† and operationalized by sociometric ratings that were collected from peers during kindergarten. One problem with this operationalization is the ability to comprehensively scale the true feelings of one peer toward another, especially during younger years. Scales, questionnaires, and observations might be too incomplete to capture the true meaning behind the dynamics of peer to peer interactions. Another issue is of how to evaluate separate peer groups. Many times classrooms encompass only a selection of developed peer groupings throughout the grade, and might be unfairly balanced toward one group. An example of groupings would be defined by the terms, â€Å"popular,† â€Å"punk,† or â€Å"nerds. † The research might be biased toward one group, if only because they were over represented in a class room. The variable Peer Exclusion was conceptualized as â€Å"the extent to which children were the target of peers’ nonaggressive rejecting behaviors, including behaviors such as ignoring, avoiding, or refusing to associate with them in the classroom context† (Buhs et al. , 2006, p. 3). The Variable Peer Abuse—the second form of peer mistreatment—was conceptualized to mean â€Å"the extent to which children were recipients of classmate’s aggressive and harassing behaviors† (Buhs et al. , 2006, p. 3). These two variables contained indicators to distinguish between chronic peer abuse, and situational peer abuse. Again, the issue that arises is the effectiveness of these measures. The interactions between childhood peers are complex, and can change daily. The variables Classroom Participation, and School Avoidance were used to measure disengagement from the classroom environment. A large issue with this is how to distinguish individuals who might be avoiding class as an outcome of separate circumstances. If poor participation and avoidance was only observed from the angle of peer interactions, then this view is biased toward the study. The study is seeking a correlation, and if outside factors aren’t controlled for, then they will biasly effect the results of their study. A child’s family life, neighborhood, economic status, innate ability, among other factors, could influence all of the variables that this study examines. The last variable, Achievement, was defined as â€Å"the accuracy with which children could solve progressively more advanced reading, mathematics, and spelling problems on an individualized achievement test† (Buhs et al. , 2006, p. 4). The issue that comes to mind with this variable is the way it uses tests to gauge â€Å"achievement†. Some students fare better on tests than others, while some students take time to develop adequate test taking skills. Another problem is how to control for separate curriculums in different classrooms, and the quality of what is being taught. Data (From the text) Buhs et al. , 2006, p. 5 Participants The data used in this investigation were gathered from a total sample of 380 children (190 girls These children were followed longitudinally from age 5 (kindergarten) to age 11 (fifth grade31 kindergarten class rooms across 10 schools, and by the fifth-grade data collection period, children were in 162 different classrooms across 32 schools. The sample contained nearly equal proportions of families from urban, suburban, or rural midwestern communities, and the sample’s ethnic composition was 17. 4% African American, 77. 1% Caucasian, 1. 6% Hispanic, and 3. 9% â€Å"other. † Family incomes were distributed as follows: 10. 9% of the sample reported total household incomes from $0 to $10,000, 10. 9% reported incomes from $10,000 to $20,000, 12. 6% reported incomes from $20,000 to $30,000, 12. 6% from $30,000 to $40,000, 12. 9% from $40,000 to $50,000, and 40. 3% reported incomes above $50,000. Results The study reports it’s results as, â€Å"peer group rejection is predictive of a range of chronic, negative peer behaviors that may alter both the social environment of the classroom and children’s adaptive responses within that context across the elementary school years. † (Buhs et al. , 2006, p. 11). It suggests that the facet of peer exclusion leading to reduced participation, and ultimately delayed achievements needs further study. It goes on to say that with further study, and thus more knowledge, an empirically based intervention program can be developed. Conclusion It can be argued that to have a complete understanding of the ever evolving and complex world of the social interactions in a school environment is close to impossible. The authors came into their study with a set premise, and expectations of the outcomes, and have seemed to found what they were searching for. The question becomes, how valid are the author’s findings, and can they be applied in a general manner across learning environments. I believe studies that look at complex interactions between children over several years, such as this study, might have too many outside interactionary forces that could effect the data and results.

Karl Landsteiner, The Brilliant And Skillful Scientist...

Karl Landsteiner, the brilliant and skillful scientist from early twentieth century Vienna, is one of the most influential persons in modern science. He has had a major impact on today’s society, as a result of his discovery of the blood groups and of the Rhesus (Rh) Factor. His work continues to have a huge impact on today’s society in the areas of blood transfusions and the effect of the rhesus factor during pregnancy and childbirth. He has also made many other contributions to science, such as in the areas of the immunology of syphilis and work with transfusion of poliomyelitis. His works eventually earned him a Nobel Prize as well as allowed him to publish papers on his findings. Karl Landsteiner dedicated most of his life to working in science. He was born in Vienna on June 12, 1868. Landsteiner’s interest in science rocketed as he began his studies at the University of Vienna. He graduated from there in 1891. While studying at the university, his focus of study was biochemical research. In fact, Landsteiner is known at the founder of biochemistry. After graduating from the University, he believed it would suit him best to leave Vienna and work in labs. The lab work he performed furthered his education and provided him with experience he would not have been able to obtain elsewhere. Landsteiner’s time in the labs did not last long before he returned to Vienna, where he began working in hospitals which sparked his interest in immunity and the nature of antibodies. A
