摘要
基础化学实验室设计、开发这样的一个评估系统,即学生在上课前将该堂课所用的基本操作拍摄成3~5 min的视频,上传到系统中。由教师批改通过的才能进入实验室,完成该实验的学习。采用这种方式既可以提高学生学习的主动性,又可以减少实验耗材节约教学成本。
An evidence centered design approach was used to develop, implement, and assess a novel and innovative digital evaluating system. Each student in a large lecture course created a video demonstrating how to use the glassware. The video was uploaded into the evaluating system, which allowed instructors to give each student feedback on their technique and to either accept or deny the video. The digital evaluating system significantly and positively impacted classroom practices wherein the students learned to experimental operation more effectively and improved their knowledge, confidence.
