近年来,国内外教育界愈来愈重视开放数学教育,重视教会学生掌握和利用数学工具去准备后继发展性学习及解决实际问题,充分发挥学生的自主性,实践性,创造性。设计数学开放题是培养学生创新精神的一个重要内容。现具体谈谈我对数学开放题的认识和体会。一、数学开放题的种类目前通常认为,数学开放题是相对于传统的封闭题而言的,其特征是题目的条件不充分,或条件多余,或结论不确定。正因为这样,开放题的解题策略也往往是多种多样。1.策略性开放题
In recent years, the education circles both at home and abroad pay more and more attention to open math education. They attach great importance to the students ’mastery and use of mathematical tools to prepare for further developmental learning and solve practical problems, and give full play to students’ autonomy, practicality and creativity. Design mathematics open question is to cultivate students an important part of innovative spirit. Now I specifically talk about my understanding of mathematical open questions and experience. First, the type of mathematical open question Currently generally considered open question is relative to the traditional closed questions, characterized by the conditions of the topic is not sufficient, or the conditions are redundant, or the conclusion is uncertain. Because of this, the open problem solving strategies are often varied. 1. Strategic open question
