生物学是一门以实验为基础的自然学科,实验教学可以帮助学生形成概念,理解和巩固生物学知识;帮助学生掌握一些常用的生物学实验的基本技能,培养学生实事求是、严谨细致的科学态度和科学方法。所以,做好实验是生物教学中必不可缺少的环节,但实验教学中又存在许多问题。下面笔者就有关实验与大家共同探讨一下。一、精选实验对于实验很多老师抱怨课时紧张、班额大、实验教学困难等,实际上是很多老师自身实验操作不熟练、不规范、怕麻烦。但方法总比困难多。鉴于此,我建议精选实验,有的放矢。每个学期根据情况精选一到两个典型实验或探究。如:必修一共有九个实验,四个探究,我们可以
Biology is a natural science based on experiment. Experimental teaching can help students to form concepts, understand and consolidate biological knowledge, help students master some common basic skills in biological experiments, and develop students’ realistic and rigorous scientific attitude And scientific method. Therefore, to do a good job in biology teaching is an indispensable part, but there are still many problems in experimental teaching. The following author on the experiment and we discuss. First, the selected experiment For the experiment many teachers complained about class hours, classes, experimental teaching difficulties, in fact, many teachers are not skilled in their own experimental operation, non-standard, afraid of trouble. But the method is always more difficult than it is. In view of this, I suggest a selection of experiments, targeted. Choose one or two typical experiments or inquiries in each semester depending on the situation. Such as: Compulsory a total of nine experiments, four to explore, we can
