针对“阿基米德原理”的教学实践,阐述了“还原规律发现过程”的教学策略对于发展学生理性思维能力的必要性。通过“情境创设、生成问题、设计实验、收集数据、得出结论、拓展应用”的展示,探讨物理规律的教学要以学生原有的认知水平为起点,创设与规律的发现过程相似的情境。要求教师必须对原教材进行重新组织与二次创作,引导学生经历物理规律发现的过程,使之成为学生课堂思维活动的源头活水,以促进物理规律教学的创新,切实提高学生的思维水平和创新能力。
According to the teaching practice of “Archimedes principle”, this paper expounds the necessity of teaching strategies of “the discovery process of restoration rules” for developing students’ rational thinking ability. Through the “situation creation, generating problems, designing experiments, collecting data, draw conclusions, expand the application of ” display, to explore the teaching of physical laws to students’ original cognitive level as a starting point, founding and regular discovery process is similar Situation. It is required that teachers must reorganize and create the original textbooks to guide the students to go through the process of discovering the laws of physics and make them become the source of living activities in the students ’classroom thinking activities so as to promote the innovation of the teaching of physics and effectively raise the students’ thinking level and innovation ability.
