为了保证实验效果,调动学生对实验教学的兴趣和积极性,我们应针对初中学生的实际,在遵循因地制宜、简单方便、实验效果好的原则下,从实验材料、实验用具、实验方法三个方面不断变化教学模式和策略,改进实验器材和实验方法,综合运用各种教学方法,以提高生物实验课的质量和效率。同时,教师一定要注意对学生进行实验规则和技能的教育,指导学生精心设计实验的内容、步骤和项目,以达到应有的实验目的。多年的教学实践告诉我们,生物实验教学必须始终坚持三个基本原则,即客观性原则、严谨性原则、灵活性原则。
In order to ensure the experimental effect and arouse students' interest and enthusiasm in experimental teaching, we should follow the actual conditions of junior middle school students and keep to the principle of adapting to local conditions, simple and convenient, and good experimental effect, from three aspects of experimental materials, experimental utensils and experimental methods Changes in teaching mode and strategy, improve experimental equipment and experimental methods, the comprehensive use of various teaching methods to improve the quality and efficiency of biological experiments. At the same time, teachers must pay attention to students' experimental rules and skills education, guide students to elaborate the contents of the experiment, steps and projects in order to achieve the desired experimental purpose. Years of teaching practice tells us that biological experiment teaching must always adhere to the three basic principles that objectivity, rigor and flexibility principles.
