如何提高学生实验效果?改革实验教学方法是值得研究和探讨的课题,我在这方面作了一些尝试和摸索。一、改验证性实验为探索性实验中学实验的目的,一般是验证所学的知识。常规的实验课一般为教师讲课一学生做实验一教师总结,因而出现了“三多一少”,即教师包办多、示教多、讲解多、学生操作少,学生往往处于被动地位。这种教学方法在很大程度上束缚了学生的智能开发和动手能力的培养。如能通过实验来获得新知识,也就是把实验由验证 How to improve students’ experimental results? The reform of experimental teaching methods is worthy of research and discussion. I have made some attempts and explorations in this area. First, change the verification experiment to the purpose of the exploratory experimental middle school experiment, generally verify the knowledge learned. The conventional experimental course is generally for the teacher to lecture a student to do the experiment a teacher summary, so there has been “more than three and one less”, that is, teachers have more packages, more teaching, more explanation, less student operations, students are often in a passive position. This kind of teaching method greatly constrains students’ intellectual development and hands-on training. If you can gain new knowledge through experimentation, that is, verify the experiment.
