Preface In this research I will examine the effects of class size on student achievement. The class size debate is an age-old debate in American education. The debate centers on whether class size is a factor that could influence student achievement. Currently many have moved into very large or small classes. As a student I am interested in seeing how class size might affect my academic performance. The research team was contacted on March 1, 2015. I am using five sources, 3 peer-reviewed journal articles, 1 journal article, and 1 journal article. Annotated Bibliography Inquiry Question: How does class size affect student achievement? Attwood, Rebecca. “Size matters for student grades.” Times Higher Education “Class Size and Student Achievement at a Public Research University: A Cross-Classified Model.” Higher Education 51.8 (2010): 701-723. Premier of academic research. Network. March 8, 2015. This article addresses issues inherent in previous studies and reviews that have questioned the influence of class size on student grades, and highlights to other researchers in this area how these issues could cause discrepancies in results of research. The article is based on using statistics and data that have been conducted in previous studies since 1990. It shows that most of these studies applied two approaches, the “constructivist” approach which concludes that class size has a significant effect on the student's grade because the student has a great opportunity to interact with the instructor in small classes (Johnson). The second approach is the “behavioral” one which concludes that class size has no impact, the primary factor in student performance is the behavior and skills of the instructors within the class (Johnson). Furthermore, the article indicates that the most popular finding from thesis studies was that “small classes can often lead to better grades” and “increasing class size has a significant negative effect on final grades” (Johnson). The article is written by Iryna Johnson, a higher education researcher at Auburn University, which gives the article added credibility (“About Us – Staff.”). Additionally, the article was published by Higher Education, an international journal of higher education studies, which reports studies on issues in universities and colleges (“Higher Education - Springer.”). I will use this source to show the two approaches that have been taken in researching the area and provide the evidence that has been used to support each approach. This article is great for
