在中学阶段,学生实验主要是验证书本知识,习得基本技能,掌握基本的科学实验方法,培养实验能力和严谨的科学作风。而学生要做好一个实验,就必须具备一定的理论知识(如实验原理、方法和步骤等),掌握一定的实验技能,具有一定的实验能力。三者之间是相互协调、互为促进的关系。因此,生物实验教学,不仅涉及到了认知领域,同时也涉及到技能领域和情感领域。故笔者认为,生物实验教学目标可以分为理论知识、观察思考和操作技能三个部分。 1.理论知识部分这一部分包括生物实验原理、方法、步骤以及实验
In the middle school stage, students’ experiments mainly verify book knowledge, acquire basic skills, master basic scientific experiment methods, cultivate experimental ability and rigorous scientific style. To do a good experiment, students must have some theoretical knowledge (such as experimental principle, methods and steps), to master a certain amount of experimental skills, have a certain experimental ability. The three are coordinated and mutually reinforcing. Therefore, biological experiment teaching not only involves the cognitive field, but also relates to the field of skills and emotion. Therefore, I believe that the biological experiment teaching objectives can be divided into theoretical knowledge, observation and operation skills of three parts. 1. Theoretical knowledge section This section includes the principles of biological experiments, methods, procedures and experiments
