基于问题式学习的数据驱动混合式教学模式构建与实证研究——有机化学

Construction and Empirical Study of Data-Driven Blended Learning Based on Problem-Based Learning:Organic Chemistry

基于“以学生为中心”的教育理念,针对基于问题式学习(PBL)的有机化学教学中存在的问题,进行了基于PBL的数据驱动混合式教学改革,并以有机化学课程为例进行了实证研究。线下教学内容注重根据学生线上自主学习的时长和测验统计等学习数据找到学生最近发展区,弹性决策课堂教学内容和活动,重点解决线上学习中的难点问题,并聚焦学生课堂的深度学习与个性化教学,实现了线上和线下学习活动的有机融合。问卷调查和学习行为分析结果表明,基于PBL的数据驱动混合式教学做到以学生为中心,个性化教学,持续改进教学效果,是提升学生学习质量的一种有效的教学模式。

Based on the educational concept of“student-centered”,a data-driven blended learning based on problem-based learning(PBL)is designed to solve the problems in the PBL learning of organic chemistry.An empirical study was carried out using the curriculum“Organic Chemistry”as an example.The offline teaching content focuses on finding the student's zone of proximal development according to the student-learning data,such as the duration of students'online self-learning and test statistics.According to the student-learning data,decisions on teaching content and activities were flexibly adjusted,focusing on solving difficult problems in online learning,and focusing on students'deep learning and personalized teaching in the classroom.This teaching mode realizes the deep integration of online learning and offline learning activities.The results of questionnaire survey and behavior analysis show that data-driven blended learning based on PBL is an effective teaching mode to improve students'learning quality,with advantages of student-centered,individualized instruction,and continuous teaching improvement.
