建构主义认为,学生要认识的知识基本上都是未知的,学生学习不是被动接受知识的过程,而是通过理解学习内容,运用他们头脑中的已有知识去探索未知的过程.在探索过程中会碰到种种困难,因此需要借助科学的想象,大胆进行合理猜想并验证猜想,从而自主建构新知识.苏科版初中物理教材在照顾知识体系性的同时积极倡导以自主、合作、探究的学习方式,力求在探究活动的情景设计中体现“科学探究”要素内涵,较多的创设一些学生意想不到的探究情景,安排一些新颖的课堂探究活动,较多的创造一些学生探究、思考、动手的机会,鼓励学生相互间的交流与合作,并逐步将 Constructivism holds that the knowledge to be recognized by students is basically unknown. Students’ learning is not a process of passive acceptance of knowledge, but through the understanding of learning content and using the existing knowledge in their minds to explore the unknown process. Will encounter various difficulties, so we need to use scientific imagination to boldly make reasonable conjectures and verify the conjecture, so as to construct new knowledge independently.Suchu junior high school physics textbooks in the care of the knowledge system at the same time actively advocating with independent, cooperative and exploratory learning In the design of inquiry activities, it tries hard to reflect the connotation of “scientific inquiry” elements, create more students’ unexpected inquiry scenarios, arrange some novel classroom inquiry activities and create more students to explore, think, Hands-on opportunities to encourage students to communicate and cooperate with each other, and gradually
