Student engagement in organising extracurricular activities: Does it matter to academic achievement?

This retrospective correlational study aimed to clarify the relationship between student engagement in organising extracurricular activities (ECAs) and academic achievement among pre-clerkship students. Data were from pre-clerkship students who enrolled during the 2012-2016 academic years at the Faculty of Medicine, Chulalongkorn University. Each cohort was followed for three consecutive years from the first to the third year of their 6-year program. The dependent variable was academic achievement, measured by grade point average (GPA). The independent variable was the level of involvement in organising ECAs, divided into breadth and intensity for each type of involvement. The results revealed that academic achievement had a linear correlation with the frequency of organising educational activities (r[1463] = 0.10; p < 0.001) and the frequency of organising community development and volunteering activities (r[1463] = -0.057; p = 0.030). Additionally, academic achievement had a curvilinear relationship with the frequency of organising recreational and miscellaneous activities, with a point of diminishing return at 1 activity per 3 following years. In summary, there were three relationships - positive linear, negative linear, and curvilinear - between academic achievement and student engagement in ECAs, based on the type of activity. Each should be supported in different ways to improve academic achievement.
