The Application of a Team-Based Learning Approach Enhances Students' Academic Performance

Objectives

This study evaluated the implementation of a Team-Based Learning modified TBL approach in Biotechnology and Chemistry modules at the University of Azad Jammu and Kashmir and explored its impact on students' academic performance and perceptions.

Background

Traditional lecture-based methods in higher education have faced criticism for limited effectiveness in engaging students and fostering critical thinking. The modified TBL approaches have increasingly been adopted in science education to promote collaborative learning and active participation.

Materials and Methods

A quasi-experimental pre-test/ post-test educational intervention study was conducted during the 2023/2024 academic year involving fourth-year Biotechnology and Chemistry students at the Faculty of Science, University of Azad Jammu and Kashmir. The same cohort of students participated in both pre-and post-intervention assessments. The modified TBL intervention included pre-class preparation materials, team-based discussions, and application-focused activities. Academic performance before and after the intervention was compared using paired statistical analysis. Student perceptions regarding the modified TBL experience were also collected using a structured post-lecture survey.

Results

Students demonstrated significant improvement in post-course assessment scores following implementation of the modified TBL approach compared with traditional lecture-based teaching (p<0.05). Survey responses indicated positive perceptions regarding student engagement, collaboration, preparation, and understanding of course content. Most students reported that the modified TBL sessions improved participation and promoted deeper learning. Data are presented as mean ± SD. Statistical analysis was performed using paired t-test (*p<0.05).

Conclusion

The findings suggest that modified TBL may enhance student engagement and academic performance in Biotechnology and Chemistry education. However, further studies using larger sample sizes, validated assessment tools, and long-term evaluation are required before broader curriculum-wide implementation.
