概念是对事物本质属性的归纳概括,具有高度抽象性.同时,概念又是分析和解决问题的基础,是构建知识的重中之重.在高中生物教学实践中,概念教学是基础内容,也是促进系统构建生物知识的基础.但因教学中对概念教学的忽视,学生在生物学习过程中因概念掌握不到位,从而导致解决问题过程中错误出现,影响其学习成绩.一、借助感性材料,使抽象概念具体化概念是对事物本质属性的概括,凝练且较为抽象,如果单纯地让学生从文字角度去分析概念,自然不能让其更好地理解
Concept is the generalization of the nature of things summarized with a high degree of abstraction at the same time, the concept is the basis for analysis and problem solving, is to build knowledge of the top priority in high school biology teaching practice, the concept of teaching is the basic content, but also Promote the system to build the foundation of biological knowledge.But ignored in the teaching of concept teaching, students in the biological learning process because of the concept of master not in place, resulting in errors in the process of solving problems, affecting their academic performance.A, with the help of sensuous materials, To concretize the concept of abstract conception is to summarize, concise and abstract the nature of things. If we simply let students analyze concepts from a literal perspective, they can not naturally understand them better
