化学是一门以实验为基础的自然科学,在新课改实施过程中、创新教学理念过程中,实验教学发挥着极其重要的作用。在化学实验教学过程中,无论课堂演示实验还是学生实验,大部分实验都会获得预期效果,但由于特定原因某些实验可能会得到与预期不相符的结果。准确分析出原因,并做出恰当的改进是我们教师应该思索的问题。在化学实验教学中,当我们不可避免地会遇到一些与预期效果不相符的情况。这里我归纳了一些在高中化学实验中遇到的异
Chemistry is a natural science based on experiments. In the process of implementing new curriculum reforms and innovating teaching ideas, experimental teaching plays an extremely important role. In the course of chemical experiment teaching, most experiments will achieve the desired results, whether in classroom demonstration experiments or student experiments. However, due to specific reasons, some experiments may result in inconsistent expectations. Accurately analyzing the causes and making appropriate improvements are questions that our teachers should think about. In chemical experiment teaching, when we inevitably encounter some situations that are inconsistent with the expected results. Here I summarize some of the differences encountered in high school chemistry experiments.
