现代数学论研究指出:从本质上讲,感知不是学习的根本原因,产生学习动力的根本原因是问题,问题是诱发和激起求知欲的关键。问题教学的策略中“疑”贯穿于整个教学过程,从教师课前设疑,学生学时质疑,师生互动中探疑,到学生学后释疑,问题在疑问中一个个产生,又在一次次活动中解疑,教学策略自然呈现:“预设→激发→求知→生成”。 Modern mathematical theory points out: In essence, perception is not the fundamental reason for learning, the root cause of learning motivation is the problem, the key is to induce and arouse curiosity. Problems in teaching strategies “suspect ” runs through the entire teaching process, from the teachers suspected of class questions, students questioned class hours, teachers and students in the interaction of suspicion, to students after school suspense, the question arises one by one in doubt, and Dispute over time and again activities, teaching strategies naturally appear: “default excitation knowledge generate ”.
