在氨基酸的性质教学中,我们发现各版本高中教材没有实验来验证氨基酸的性质,因缺少直观认识,使很多学生对它的性质产生了质疑。我用生活中常见的调味品味精设计了关于氨基酸性质的探究实验,运用本实验可大大提高学生的学习兴趣,增强学生对氨基酸性质的理解。 In the teaching of the nature of amino acids, we found that all versions of high school teaching materials did not have the experiment to verify the nature of amino acids, which led many students to question its nature due to lack of visual understanding. I used the common seasoning MSG in life to explore the nature of the amino acid experiment, the use of this experiment can greatly enhance students ’interest in learning and enhance students’ understanding of the nature of amino acids.
