开放性教学包括教学内容、学生活动和学生与教学内容之间相互作用等几个方面。而开放式数学教学的目标是:充分尊重学生的主体地位,通过数学教学,在学生获取数学知识的同时,让他们主动学习自行获取数学知识的方法,学习主动参与数学实践的本领,进而获得终身受用的数学能力、创造能力和社会活动能力。教师在教学中,让学生能按各自不同的目的、不同的选择、不同的能力、不同的兴趣选择不同的教学内容,能力较强的学生能积极参与数学活动,有进一步的发展机会;能力较低的学生也能参与数学活动,完成 Open teaching includes teaching content, student activities and interaction between students and teaching content. The goal of open mathematics teaching is to fully respect students’ subjective status, and through mathematics teaching, students should acquire the knowledge of math while learning how to acquire math knowledge by themselves and acquire the ability to take the initiative to participate in math practice so as to obtain lifelong learning Ability to use mathematics, ability to create and social activity. Teachers in teaching, so that students can according to their different purposes, different choices, different abilities, different interests choose different teaching content, strong ability of students can actively participate in math activities, there are further opportunities for development; ability to compare Low students can also participate in math activities to complete
