生物学是一门以实验为基础的自然科学,许多生物现象只有通过实验才能得到解释,各种生物体的形态结构必须通过实验才能观察清楚,所以生物实验教学在高中生物教学中占有非常重要的地位。下面结合本人的教学实践谈谈在高中生物实验教学中的几点尝试。一、通过生物实验教学,培养学生积极参与的意识在以往的学生实验中,学生完全按规定的步骤进行。学生成了不用思考的机械操作者,甚至到实验结束都没有留下完整的印象。这种教学没有给学生留下积极思维的空间和余地,也不允许他们有任何意义上的标新立异,抑制了学生学习的主动性和思考的独立性,而现代教育就是要引导学生积极参与。
Biology is an experiment-based natural science. Many biological phenomena can be explained only through experiments. The morphological structure of various organisms must be clearly observed through experiments. Therefore, biological experiment teaching plays a very important role in biology teaching in senior high schools status. The following combination of my teaching practice talk in high school biology experiment teaching several attempts. First, through the biological experiment teaching, cultivate students’ awareness of active participation In previous student experiments, the students carried out exactly according to the prescribed steps. Students became mechanical operators without thinking, and did not even leave a complete impression at the end of the experiment. This kind of teaching does not leave room for students to think negatively, nor does it allow them to have any unconventional meaning in any sense, which inhibits students’ initiative and independence of learning. However, modern education is to guide students to actively participate.
