笔者从教学实践出发,针对平时教师教学的“妙解”进行再思考和再加工.以小船过河最小位移问题为例谈正确的教学内容应该是贴近学生的最近思维发展区,用正交分解法代替常见的所谓的“妙解”——三角形法.以求球形容器滴水的重心变化的常见“妙解”为例寻找其背后的思维源头,提升学生的思维品质,使高中物理的教育功能更为强大.
Based on teaching practice, the author conducts rethinking and reprocessing of the “wonderful solution” of teachers’ teaching at ordinary times.Taking the problem of the minimum displacement across the river as an example, the correct teaching content should be close to the recent thinking development area of students, Decomposition method instead of the common so-called “Miaoshang ” - the triangle method to find the common “wonderful solution ” to change the center of gravity of the spherical container drip as an example to find the source of thinking behind them to enhance students’ thinking quality, Enable high school physics education function more powerful.
