Abstract:

It was aimed to investigate the effect of problem-based learning activities about Coenzymes on undergraduates' achievement and attitude towards biochemistry lesson in this study. For this purpose, 48 undergraduates enrolled in the Department of Medical Laboratory Techniques were randomly stratified to experimental and control groups. While students in the experimental group learned the subject with problem-based learning activities, the subject were taught based on traditional teacher-centered approach in the control group. For data collection, foreknowledge test (KR-20=0.84) and coenzymes achievement test (KR-20=0.846) developed by researchers, attitude scale (α=0.82) adopted by attitude toward chemistry lesson (Tarhan, 2008) and semi structured interview form were used. According to results, problem-based learning activities were effective in contrast to traditional approach for promoting students' achievement and attitude towards lesson.
