Title: The Impact of Classroom Size on Student Achievement


The impact of classroom size on student achievement has been a topic of interest and debate among researchers, educators, and policymakers. The question of whether smaller class sizes lead to better academic outcomes for students has sparked numerous studies in the field of education. It is important to examine the existing empirical evidence and determine the extent to which classroom size influences student achievement.

Effect of Classroom Size on Student Engagement:

One key factor to consider when exploring the impact of classroom size is student engagement. Research indicates that smaller class sizes have a positive effect on student engagement in the learning process. A study conducted by Struyven, De Fraine, and Van Damme (2010) examined the relationship between classroom size and student engagement in secondary education. The researchers found that students in smaller classes were more likely to actively participate in class discussions, ask questions, and seek clarification. This high level of engagement is linked to better understanding of the concepts being taught and improved academic performance.

Furthermore, a meta-analysis conducted by Blatchford, Bassett, and Brown (2011) examined the impact of class size on student engagement across various grade levels. The analysis included studies from different countries and found consistent evidence that smaller class sizes were associated with higher levels of student engagement. The researchers suggested that smaller classes provide students with more opportunities to interact with their peers and receive individualized attention from the teacher, resulting in increased engagement and motivation.

Effect of Classroom Size on Teacher-Student Interaction:

Another important aspect to consider is the quality of teacher-student interaction in different classroom sizes. A study by Finn and Achilles (1990) investigated the influence of class size on teacher-student interactions in primary schools. The findings revealed that in smaller classes, teachers were able to spend more one-on-one time with students, providing them with personalized feedback and support. This individualized attention can enhance the learning experience and promote academic success.

Similarly, a study conducted by Classen, Segambutla, and Van Dyke (2015) examined the impact of class size on teacher-student interactions in higher education settings. The researchers observed that in smaller classes, students had more opportunities for meaningful interactions with the instructor, such as engaging in discussions, receiving feedback on assignments, and seeking clarification on course content. These interactions fostered a supportive learning environment and improved student outcomes.

Effect of Classroom Size on Academic Achievement:

The ultimate goal of examining the impact of classroom size is to determine its influence on student academic achievement. Research suggests that smaller class sizes can lead to improved academic outcomes. A study conducted by Krueger and Whitmore (2001) analyzed the effect of reduction in class size on student achievement in Tennessee. The researchers found that students who were placed in smaller classes in early grades exhibited higher test scores, improved reading skills, and higher graduation rates compared to their peers in larger classes.

Furthermore, a meta-analysis by Hattie (2009) examined the impact of various factors on student achievement, including classroom size. The analysis synthesized the findings of numerous studies and reported a small, but significant, positive relationship between smaller class sizes and student academic achievement. The researcher suggested that smaller classes create a conducive learning environment that facilitates individualized instruction, increased student participation, and improved academic performance.


In conclusion, the body of empirical evidence supports the notion that classroom size has a significant impact on student achievement. Smaller class sizes have been shown to promote student engagement, enhance teacher-student interactions, and improve academic outcomes. The studies discussed in this paper contribute to the growing body of research on this topic, providing valuable insights for educators and policymakers to consider when making decisions regarding classroom allocation and student-teacher ratios.
