案例教学法在本科生和研究生教学应用中的差异

Differences of application of case teaching method to teaching of undergraduates and postgraduates

为了研究案例教学法在不同人群中教学效果的差异,以2015至2017级食品科学与工程专业本科生和2018至2020级化学工程与技术学科研究生为研究对象,将案例融入二者共有的色谱分离技术章节内容中,并通过问卷调查和成绩分析对教学效果进行评价。教学实践表明,案例教学法能提高本科生和研究生的学习主动性和课堂活跃度,研究生的自身满意度、理解能力和方案设计能力分别提高22.8%、12.2%、20.3%,本科生的分别提高12.9%、5.0%、15.9%,研究生的案例教学效果显著高于本科生。本研究结果能为不同人群的教学方法选择提供参考,从而提高学生的学习兴趣,提升教学质量。

In order to elaborate on the differences of teaching effectiveness in different groups attained by the case teaching method,the undergraduates of class 2015 to 2017 majoring in Food Science and Engineering and the postgraduates of class 2018 to 2020 majoring in Chemical Engineering and Technology were selected as the research objects.The cases were integrated into the content of chromatographic separation technology which they shared,and the teaching effectiveness was evaluated through the questionnaire and examination analysis.The results show that the case teaching method could improve their learning initiative and stimulate the class atmosphere.The improvements of self-satisfaction,understanding ability and scheme design ability for postgraduates are 22.8%,12.2%,20.3%,respectively,while those for undergraduates are 12.9%,5.0% and 15.9%,respectively.Thus it is safe to conclude the improvement of postgraduates is significantly higher than those of undergraduates after applying the case teaching method.This may provide reference for the selection of teaching methods for different groups in order to foster students’ interest and boost teaching quality in the future.
