给学生呈现学习内容或提出思考题时,常说要让学生“跳一跳摘到桃子.”也就是说要根据学生的实际,既要控制好学习内容或思考题的难度,还要让一部分学生经过思考、探索后能够得出问题的解答.否则对提高学生学习兴趣是无益的,甚至还会挫伤学生学习的 When presenting students with learning content or asking questions, it is often said that students are required to “jump to peaches.” That is to say, according to the students’ actual conditions, it is necessary to control the difficulty of learning content or thinking questions. Let some students think through and explore, then they can get answers to the questions. Otherwise, it would be useless to improve students’ interest in learning, and it would even dampen students’ learning.
