This is an essay for academic preparation course. I'd like to have it been reviewed and welcome everyone's comments, especially on grammar and structure, thank you.

Is the class size relative to better academic achievement?

The importance of education is the core value of all human society. Thus, how to improve the performance of students is the heated subjects of endless debate. When class size is mentioned, most studies refer to 20 students as a small class, and a large one is more than 20. In Asia, large class size is common for every level of school. In the elementary school that I studied, the classroom was usually full of approximately sixty students. Under this situation, our teacher did not give us any free time to discussion nor provide feedback for individuals. The whole school year followed by tight schedule; standard and frequent examinations were the effective ways to test student’s performance. As a result, students tried hard to continue high scored, otherwise, harsh punishment would occur. Considered the improvement academic achievement, there is common consensus among the beneficial ways of class-size reduction in many countries. To be sure, there have been numerous studies in the U.S. concentrating on this topic. This essay will discuss the relative benefits of both small and large class sizes.

There are a lot of factors that contribute to students’ performance. Overtime, the performance of students is widely better as a result of class-size reduction; numerous studies also indicated those benefits following by reducing the class size.  According to these conducts, some major key points are worth to be addressed as: more interaction between students and teachers, encouraging group discussion and these students are more likely to become healthier in their later lives.
First of all, unlike large classes, fewer students in class can avoid interruption from peers, and also give teachers more opportunities to focus on individually. Students are encouraged to team up together and have more discussions, which not only gives teachers more room of flexibility, but it also modifies education style by the ways of examining the students closely. Meanwhile, because the students are well educated, they may have sufficient knowledge to maintain healthy lives and avoid unnecessary medical cost.
In addition, some analysts agreed that those students in kindergarten prosper good study habits and it is likely to persist for long time. However, as maintained by existing records showed that since 1969, over 28 years, the United States has experienced relative decrease in student-teacher ratios dramatically, despite a negligible increase in academic performance.
