The Relationship between Class Size and Academic Performance among Grade 11 Senior High School Students of Eduardo Cojuangco National Vocational High School

Abstract

Research has shown that class size affects the academic performance of students in various scholastic settings. Smaller class sizes allow teachers to pay more attention to each individual student’s learning, thereby contributing positively to these students’ academic performance. This study aimed to determine whether these research findings apply to the Philippine public school setting. Thus, it asked how class size and student performance are related among senior high school students in a public national vocational high school in the Philippines. The researchers used a quantitative research design in which the class size and general point average of n=266 randomly selected senior high school students were subjected to a Simple Regression Analysis. Results showed a significant inverse correlation between class size and academic performance, with students belonging to smaller class sizes performing better in their academics. These results are discussed in light of the implications on the effectiveness of class setups in the Philippine public school setting.
