“相异构想”指的是学生头脑中与科学的概念内涵不一致的看法和观点,是先入为主、由来已久的东西,它极大地抗拒新的科学物理概念的同化、顺应,给正规的物理教学带来严重障碍,影响了物理教学质量的提高.在高中物理教学中,学生对物理概念的理解、掌握程度直接影响着学生物理学习的效果,严重的影响了物理教学质量.通过对学生头脑中的某些“相异构想”阻碍建立、接受、理解科学物理概念现象进行了研究,结合相异构想的广泛性、隐蔽性、反复性、顽固性四个特点以及相异构想的来源基础上,提出了几种转变相异构想的方法,并进行了教学实践.实践证明,新的教学方法在扭转学生头脑中的相异构想方面取得了明显的效果,新的教学方法总体上取得了较好的教学效果. “Different Conception ” refers to the views and opinions in the minds of the students that are inconsistent with the connotation of the concept of science. It is a preconceived and long-standing project that greatly resists the assimilation and adaptation of the new scientific and physical concepts, Of the physical teaching brings serious obstacles, affecting the quality of physics teaching.In the high school physics teaching, students ’understanding and mastery of the physical concepts have a direct impact on the effect of the students’ physical learning, which has a serious impact on the quality of physics teaching. Some “dissimilar conceptions” in the minds of the students impede the establishment, acceptance and understanding of the phenomena of the concept of science and physics. Based on the four characteristics of universality, concealment, repeatability and intransigence, Based on the source of the heterogeneous vision, put forward several methods to change the conception of the different, and carried out the teaching practice.Practice has proved that the new teaching method has achieved remarkable results in reversing the different ideas in the minds of the students, The new teaching methods generally achieved good teaching results.
