灵活运用多媒体技术,优化科学课堂教学

Flexible Use of Multimedia Technology Optimization of Science Teaching

科学学习要以探究为核心,实验则是学生科学探究的重要活动,对帮助学生理解和掌握理论知识,培养动手操作能力,激发爱科学的兴趣,提高学生科学素质,有着举足轻重的作用。随着科学技术的高速发展,多媒体技术辅助教学步入了课堂,又给小学科学课堂教学带来了新的发展。本文根据自己多年的教学实际,从运用多媒体技术"进行科学启蒙教育、介绍实验器材、演示实验步骤与要求、教授实验现象不明显的内容、教授抽象知识"五方面,结合教学实例,阐述在科学课堂教学中,运用多媒体辅助教学,克服实验条件的限制,提高实验的可操作性和直观性,加强实验操作的规范性、正确性,帮助学生认识、理解抽象的教学内容,从而达到优化课堂教学的目的的具体做法,以达到抛砖引玉之功效。

Science learning requires an exploration as the core.The experiment is an important activity for students＇ scientific inquiry.It plays a decisive role to help students understand and master theoretical knowledge ; develop hands-on ability ; stimulate loving in science,improve students scientific literacy.With the rapid development of science and technology,multimedia technology facilitates teaching into classrooms and brings a new development in science teaching in elementary schools. This article based on the author＇ s teaching practice for many years states utilizing multimedia technology in five aspects such as ＂scientific enlightenment education ; experimental equipment guidance ; demonstration of experimental procedures and requirements ; the content of non-experimental phenomenomabstract knowledge leaming.The author practices multimedia technology in science teaching,overcomes a limitation of experimental conditions,improves maneuverability and intuition and strengthens the standardization and correctness of experimental operation to help students understand abstract contents so as to achieve op optimizing classroom teaching practice.
