生物是一门以实验为基础的学科,生物实验具有帮助学生认识生物学基本规律,掌握生物学知识,培养学生分析问题解决问题的能力等多种功能,实验教学是生物教学的重要组成部分,近年来随着信息技术的发展,多媒体以其丰富的表现力和很好的交互性,在生物教学中大量被应用,实验教学中也开始引人多媒体辅助教学,本文结合自己的教学实践谈谈多媒体在生物实验教学中的应用。一、运用多媒体组织实验课堂教学,改变课堂结构,提高课堂效率传统的实验课教学,教师只能依靠黑板等常规手段讲解实验目的、原理、方法、步骤。因时间与条件的限制,不利于给学生讲清楚,板书清楚,也不利于指导学生实验。运用多媒体课件将实验内容投影出来,在实验前指导学生阅读实验内容,使其掌握实验目的和操作要领,理解实验原理。
Biology is an experiment-based discipline. Biological experiments have many functions such as helping students to understand the basic rules of biology, mastering biological knowledge, and cultivating students’ abilities to analyze problems and solve problems. Experiment teaching is an important part of biology teaching, In recent years, with the development of information technology, multimedia has been widely used in biology teaching due to its rich expressiveness and good interactivity. Multimedia teaching has also begun to be introduced into experimental teaching. This article is based on its own teaching practice Application of Multimedia in Biology Experiment Teaching. First, the use of multimedia organization of experimental classroom teaching, change the classroom structure, improve classroom efficiency The traditional experimental teaching, teachers can only rely on blackboard and other conventional means to explain the purpose of the experiment, principles, methods, steps. Due to the limitation of time and conditions, it is not conducive to make it clear to the students. It is also not conducive to guiding students to experiment. Use multimedia courseware to project the experiment content, guide the students to read the experiment content before the experiment, make it master the purpose of the experiment and operation essentials, understand the principle of the experiment.
