随着数学教学研究的深入,思维能力越来越受到广大师生的重视。开放题目是数学教学中激活学生思维的一条有效的途径。改变单一的封闭题型,增加开放题型,为学生提供联想机会,能够促进学生的思维由封闭逐步过渡到开放;变换观察问题的角度,利用一题多解,开阔学生思路,能够促使学生的思维由线形过渡到立体;变换题设或结论,充分利用一题多变,能够培养学生具有灵活性、深刻性和创造性思维。
With the deepening of mathematics teaching and research, more and more thought ability has been paid attention by teachers and students. The open title is an effective way to activate students’ thinking in mathematics teaching. Change a single closed question type, increase the open question type, provide students with associative opportunities, can promote the students ’thinking from gradual transition to open; change the perspective of observation problems, using one question and multiple solutions to broaden students’ thinking, can promote students Thinking from the linear transition to the three-dimensional; transform the problem or conclusion, take full advantage of a problem change, to develop students with flexibility, profound and creative thinking.
