生物实验是高中生物教学的重要环节。在实验过程中对学生进行分组能促使他们亲身实践,从而把书本上抽象的生物概念转化为直观的生物现象。分组实验的展开有助于培养学生严谨、科学的探究精神,有助于提高课堂教学的效率。但由于各种因素的干扰,在进行分组实验时会产生不稳定的心理特征,而这类心理将直接导致实验结果存在偏差或错误。一、做好实验准备,克服心理准备不足弊端一般来说,高中生物所要求的实验都是对已经学过的理 Biological experiment is an important part of high school biology teaching. Grouping students during the experiment can motivate them to practice in their own hands, thus turning abstract biological concepts in books into intuitive biological phenomena. The group experiment will help to develop students rigorous and scientific spirit of exploration, help to improve the efficiency of classroom teaching. However, due to the interference of various factors, there will be instable psychological characteristics during the grouping experiment, and such psychology will directly lead to the deviation or error of the experimental results. First, to prepare for the experiment, to overcome the psychological disadvantages of malpractice In general, the experiments required by high school biology are the theory has been learned
