数学开放题是一种新的教学模式。它主要是靠教师来引导,充分调动学生的思维能力,让学生作为课堂的主体,强调的是学生的学习自主权。数学开放题作为优化组合教学模式的地位存在。由于数学开放题是数学教学中的一种新题型,单纯的用理论性语句描述略显抽象,本文将采取举例的方法来说明数学开放题的研究和实践是有必要的。 Mathematics open question is a new teaching mode. It is mainly by teachers to guide, fully mobilize the thinking ability of students, so that students as the main body of the classroom, emphasizing the student’s autonomy in learning. The status of mathematics open question as the optimal combination teaching mode exists.
