Comparison of student perception and performance between case-based learning and lecture-based learning in a clinical laboratory immunology course

Abstract

AbstractBackground:Case-based learning (CBL), an educational method of problem-based learning, provides students with a venue to relate content learned in the classroom to performance in professional practice. This study compared CBL in the teaching of a clinical laboratory immunology (CLI) course to lecture-based learning (LBL), and evaluated the effect on students regarding the CBL.Methods:Data were collected from senior students (n=85; 46% males, 54% females) at Lanzhou University in China. The students were divided into two groups, one group was offered CBL, while the other LBL as a teaching instrument. After intervention, perceptions of both the groups about their respective teaching method were evaluated using questionnaires, the resulting scores were compared to those obtained in the LBL group.Results:The CBL group showed significantly better scores in course examination (p<0.05) as compared to the LBL group. Seventy-seven (90.6%) students in the CBL group opined that CBL improved their learning and clinical problem-solving skills. CBL also provided them with better understanding (90.6%) and preparation for examinations (90.6%). CBL group improved markedly in comparison to the LBL group with regard to learning motivation (p=0.040), clinical reasoning ability (p=0.023) and clinical problem-solving ability (p=0.022).Conclusions:Our findings demonstrate that CBL is a more effective teaching strategy as compared to LBL in a CLI course. Consequently, the implementation of CBL in teaching a CLI course helps students to improve their learning motivation, problem solving abilities and mastery of knowledge.
