随着课程教材改革的不断深入,课外活动也越来越受到重视。课外活动,对于学生拓宽知识,培养能力是一条重要途径。课外活动既是课堂教学知识的补充,也是培养学生生物学实验能力,促进实验教学的一种积极方法。 一、在课外活动中培养设计实验的能力 在生物学教学中,许多实验都是现成设计好的,学生只需按书本上规定的做法,取什么材料,放什么药品,选用什么器材和工具,按实验步骤往下做。这些验证性的实验,学生做了以后虽然知道了实验结果,但至于为什么要这样做为什么要选用这些材料和药品往往不太清楚。如稍作改动学生就会不知所措,离开了老师和
With the continuous deepening of the reform of curriculum materials, extracurricular activities have also received increasing attention. Extra-curricular activities are an important way for students to broaden their knowledge and develop their abilities. Extra-curricular activities are not only a supplement to classroom teaching knowledge, but also a positive method for cultivating students’ biology experimental ability and promoting experimental teaching. First, to develop the ability to design experiments in extracurricular activities In biology teaching, many experiments are ready-made and well designed. Students only need to follow the practices prescribed in the books, what materials to take, what medicines to use, and what equipment and tools to use. Follow the experimental steps down. In these confirmatory experiments, although the students knew the results of the experiment afterwards, it was not always clear why they should use these materials and drugs. If you make some changes, the student will be overwhelmed and leave the teacher and
