生物学通过对生物的形态、结构、生理、分类、遗传、变异、进化和生态等方面的研究来揭示生命活动的本质,是一门实践性较强的学科。事实表明,丰富多彩的自然界为生物学教学提供了大量原始素材,而多媒体正好能充分利用这些直观形象的素材进行教学,有利于充分发挥学生在学习过程中的主体地位。生物学中的重要概念处于学科中心位置,一般包括:对生命基本现象、规律、理论等的理解和解释。在笔者看来,对重要概念的理解和掌握能让学生在学习
Biology reveals the essence of life activities through the study of biological morphology, structure, physiology, classification, genetics, mutation, evolution and ecology. It is a highly practical discipline. Facts have shown that the rich and colorful nature of biology teaching provides a large number of original material, and multimedia just to make full use of these visual image materials for teaching, is conducive to giving full play to students in the process of learning the dominant position. Important concepts in biology are at the center of the discipline and generally include understanding and explaining basic life phenomena, laws and theories. In my opinion, understanding and mastery of important concepts allows students to learn
