实验教学是生物学课程的重要组成部分,它既是一类探究活动,也是基本的教学形式。新版义务教育生物课程标准要求“加强和完善生物学实验教学”。根据实验内容的不同性质,我把中学实验分为探究性实验、模拟实验和观察实验三大类。对不同内容的实验,我根据学生和学校的实际以及教师自身的特点来组织教学,使学生在实验中不仅收获了知识,同时还培养了他们的思维能力、动手能力及创新精神。一、探究性实验如探究“光对鼠妇生活影响”的实验,这是中学第一个完整的探究性实验。为了帮助学生制定好实验方案,我设计了以下问题供学生思考和讨论:1.这个实验我们要探究的问题是什么?2.实验中需要用哪些材料和用具?你将如何使用?
Experimental teaching is an important part of the biology course. It is not only a kind of inquiry activity but also a basic teaching form. The new version of compulsory education biology curriculum standards “to strengthen and improve the teaching of biological experiment ”. According to the different nature of the experiment content, I divided the high school experiment into three categories: inquiry experiment, simulation experiment and observation experiment. For experiments on different contents, I organized the teaching according to the students’ and the schools’ actual conditions and the teachers’ own characteristics, so that students can not only gain knowledge in experiments, but also develop their thinking ability, practical ability and innovative spirit. First, exploratory experiments such as exploring “light on the impact of life of the mouse ” experiment, which is the first complete middle school high-level inquiry experiment. In order to help students develop a good experimental program, I designed the following questions for students to think about and discuss: 1. What are the questions we should explore in this experiment? 2. What materials and appliances are needed in the experiment? How are you going to use them?
