To determine if there would be a difference in students' performance and level of satisfaction when taught pharmacology in a problem-based learning format as compared to traditional lecture format.
Control (n = 12) and experimental (n = 10) group means for middle-of-term examinations, final examinations, end-of-course numerical averages, and numerical scores of satisfaction were analyzed with a t test for statistically significant differences.
There was no significant difference between groups for any of the items measured, suggesting that problem-based learning and traditional lecture format may be equally effective course delivery methods. Replication with a larger sample is recommended.
The small sample size precludes generalizing results to the entire population, but outcomes of this pilot study suggest that problem-based learning may be at least as effective as traditional lecture and should be explored in larger studies.
确定与传统讲授形式相比,以基于问题的学习形式教授药理学时,学生的表现和满意度水平是否会存在差异。
采用t检验分析对照组(n = 12)和实验组(n = 10)在期中考试、期末考试、课程结束时的数值平均分以及满意度数值分数,以确定是否存在统计学上的显著差异。
在所测量的任何项目中,两组之间均无显著差异,这表明基于问题的学习和传统讲授形式可能是同样有效的课程授课方法。建议用更大的样本进行重复研究。
样本量小使得无法将结果推广至整个人口,但这项初步研究的结果表明,基于问题的学习可能至少与传统讲授一样有效,应在更大规模的研究中进行探索。
