从建构主义的角度来看,数学教学是学生自主建构数学知识的过程,在这一过程中,学生与教材及教师间产生交互作用,形成了数学知识、技能,发展了情感态度和思维品质。然而我认为,像以往那样只是表面上热热闹闹,不注意活动的有效性、有序性,或者教师过多的引导,这种教学只会束缚学生的手脚,阻碍学生思维的发展。而真正能培养创新精神和实践能力的实践活动必须是学生自主的活动,必须有深刻的观察、想象、假设、推理、探究等高层次的思维活动的加入,学生的操作实践活动才能由指令性向自主性转变。
From the perspective of constructivism, mathematics teaching is the process of students’ independent construction of mathematical knowledge. During this process, students interact with textbooks and teachers to form mathematical knowledge and skills and develop emotional attitudes and thinking qualities. However, I think, as always, it is only superficial, ignoring the effectiveness, orderliness, or excessive guidance of teachers. This teaching will only hinder students ’hand and foot and hinder the development of students’ thinking. However, the practical activities that can really cultivate the spirit of innovation and practice must be students ’independent activities. They must have profound observation, imagination, supposition, reasoning, inquiry and other high-level thinking activities to join, and students’ operational practices can be changed from the directive Autonomy changes.
