情境教学法是目前较为流行的一种教学方法,它是通过教师引导学生进入数学情境,进而引发学生思考——提出问题——解决问题的模式,帮助学生更好地学习和获取知识。在高中阶段进行“数学情境与提出问题”研究是十分必要的。围绕“数学情境与提出问题”进行课堂教学应注意:(1)创设好的情境是进行课堂教学的基础;(2)恰当引导学生提出数学问题;(3)以情境带动数学教学。具体到讲授“归纳——猜想——证明”一课,可从讲述著名的哥德巴赫猜想的产生与发展历程引入,给学生以探索求真的感染力,同时揭示从特殊到一般的探索真理的思想方法及意义。
Situational pedagogy is a popular teaching method. It guides students into mathematics situations through teachers, and then triggers students’ thinking-problem-solving modes to help students learn and acquire knowledge better. It is necessary to carry out the “major situation and raise questions” in high school. The classroom teaching around “major situation and asking questions” should pay attention to: (1) creating a good situation is the basis for classroom teaching; (2) properly guiding students to put forward mathematical problems; (3) using situation to drive mathematics teaching. Specifically to teach “induction - conjecture - proof ” a lesson can be introduced from the creation and development of the famous Goldbach conjecture, to give students the ability to explore seeking truth, and reveal from special to general Explore the way of thinking and significance of truth.
