新课标指出,高中化学教学要“有利于学生体验科学探究的过程,学习科学研究的方法,加强对科学本质的认识,增强创新精神和实践能力”。但是探究需要较多的时间和较大的空间,选择好探究主题很关键,本文从选取“贴近生活”和“贴近社会”的内容、选取有异常现象的实验、学生有争议的问题等主题进行探究。 The new curriculum standard points out that high school chemistry teaching is to “help students experience the process of scientific inquiry, learn scientific research methods, strengthen the understanding of the nature of science, and enhance the spirit of innovation and practical ability.” However, exploration requires more time and more space. Choosing the best topic for exploration is critical. This article selects the contents of “close to life” and “close to society”, selects experiments with unusual phenomena, and students have controversial Questions and other topics are explored.
