摘要
对分析化学实验教学模式改革进行了探索与实践,主要工作包括以下三方面:(1)建设分析化学实验SPOC平台,使学生可以在课堂教学前在线预习实验视频及课件,完成线上测试,达到了让学生自主学习和长期学习的目的;(2)自主编制分析化学实验测试程序,利用该程序在课堂教学中对学生进行测试,实践表明,测试既不影响正常的课堂教学,又能达到督促学生学习的目的;(3)改革对学生实验结果评定的方法,使得对学生课程成绩的评定更加客观准确,同时也能使教师及时发现学生在实验中存在的问题,帮助学生更好地完成课程学习。
In this study,the analytical chemistry experiment teaching model has been explored and practiced.The main work includes the following three aspects:(1)The analytical chemistry experiment SPOC has been constructed,which enables the students to preview the courseware and experimental video and complete the test prior to classroom teaching.The SPOC realizes the purpose to let the student study proactively and chronically.(2)The program of analytical chemistry experiment test has been developed independently and applied to test the students in classroom teaching.The practice shows that the classroom testing does not affect normal classroom teaching,but also can urge the students to study.(3)The evaluation method to the students’experiments has been reformed,which makes the assessments to the students’performances more objective and accurate.Meanwhile,the new evaluation method enables the teachers to find the problems in the experiments timely and help the students to complete the course preferably.
