实验操作技能是借助于一定的实验手段,完成一定实验任务的、符合一定实验程序的方法的随意活动。如何有效进行实验操作技能的教学,高效实现课标中“三维目标——技能目标”的培训,下面笔者就平时所做谈一些体会。一、初中实验操作的技能、教学层次与教学目标根据操作技能形成一阶段,可以将初中实验操作技能的训练分成三个相互联系、要求不同的层次,每一教学层次相应有一个教学目标,其示意图如下:
The experimental operation skills are free activities that use certain experimental methods to complete certain experimental tasks and meet certain experimental procedures. How to effectively carry out the teaching of experimental operation skills and effectively implement the training of the “three-dimensional target-skill target” in the curriculum standard, the following author will talk about some of the things he does in peacetime. First, the skills, teaching levels, and teaching goals of junior high school experimental operations form a phase based on operational skills. The training of junior high school experimental operating skills can be divided into three levels that are related and require different levels. Each teaching level has a corresponding teaching goal. The schematic diagram is as follows:
