概念是生物学习的基石,搞好概念教学是提升生物课教学效率的基础.概念是对事物客观属性的抽象概括,故而较为抽象,虽然高中学生的抽象思维能力有所发展,但在概念教学中依然要注重以直观情境作为引导,促进学生感知概念.同时,要转变以往的讲授模式,多引导学生参与生物探究活动,在合作探究中理解概念,在对比中分析,在练习中巩固.对此,本文就结合高中生物课实践,对生物概念教学作分析.一、直观导入,形象感知 The concept is the cornerstone of biological learning. The concept teaching is the basis for improving the teaching efficiency of biology courses. The concept is an abstract summary of the objective attributes of things, so it is more abstract. Although the abstract thinking ability of high school students has developed, it is in concept teaching. Still need to pay attention to using intuitive situations as a guide to promote student perception concepts. At the same time, we must change the previous teaching mode, guide students to participate in biological inquiry activities, understand concepts in cooperative inquiry, analyze them in comparison, and consolidate in practice. This article combines high school biology class practice with the analysis of biological concepts teaching. First, intuitive introduction, image perception
