Active teaching is increasingly accepted as a better option for higher education STEM courses than traditional lecture-based instruction. However, concerns remain regarding student preferences and the impact of increased course structure on teaching evaluations. Undergraduates in a non-majors neuropharmacology course were enrolled in an enriched blended course format, providing online case-based learning opportunities in a large lecture hall setting. Students working in small assigned groups solved weekly case studies developed to teach basic neuropharmacology concepts. All case study assignments were peer reviewed and content was further reinforced with a weekly online quiz. A comparison of scores on equivalent midterm and final exam questions revealed that students enrolled in the High-Structure course scored better than students from the previous year that took a more traditional Low-Structure lecture-based course. Student performance increased significantly for exam questions that required Bloom's level understanding. When surveyed, students in the High-Structure course reported some regret for the lack of traditional lecture and revealed some disapproval towards the extra work required for active teaching and peer review. Yet, we saw no change in quantitative instructor evaluation between sections, challenging the idea that student resistance towards increased work lowers course evaluation scores. Future instructors using active learning strategies may benefit from revealing to students the value of increased course structure on performance outcomes compared with traditional lecture courses.
与传统的基于讲座的教学方式相比,主动式教学越来越被认为是高等教育STEM课程的更好选择。然而,对于学生的偏好以及课程结构增加对教学评估的影响,人们仍然存在担忧。非专业神经药理学课程的本科生参加了一门丰富的混合课程,该课程在大教室环境中提供基于案例的在线学习机会。学生们以指定的小组形式每周解决案例研究,这些案例研究旨在教授基本的神经药理学概念。所有案例研究作业都经过同伴评审,并且通过每周的在线测验进一步强化内容。对同等的期中考试和期末考试问题的分数进行比较后发现,参加高结构课程的学生比上一年参加更传统的低结构讲座课程的学生得分更高。对于需要布鲁姆认知水平理解的考试问题,学生的成绩有显著提高。在接受调查时,高结构课程的学生对缺乏传统讲座表示有些遗憾,并对主动式教学和同伴评审所需的额外工作表示有些不满。然而,我们发现各部分之间教师的定量评估没有变化,这对学生对增加的工作量的抵触会降低课程评估分数这一观点提出了挑战。与传统讲座课程相比,未来采用主动学习策略的教师可能会从向学生揭示增加课程结构对学习成果的价值中受益。
