运用信息技术有效整合初中化学课堂教学模式研究探索

Research and Exploration on Effectively Utilizing Information Technology for Chemistry Classes in Junior High Schools

以网络技术和多媒体技术为核心的信息技术已成为拓展人类能力的创造性工具,我国已经在中小学中普及信息技术教育,同时要加强信息技术与其他课程的整合。化学作为一门以实验为基础的科学,需要从分子、原子的微观角度来研究宏观物质之间的反应。以现代建构主义理论为指导、具有多媒体集成和资源共享等多种强大功能的信息技术,理应在化学课堂教学中发挥更大的作用。我们以提高学生初中化学综合素质为主要目的,开展了以教师使用信息技术为主的"演示型"整合教学模式的研究和以学生自主学习与教师演示相结合的"互动型"整合教学模式的研究,并取得一定成果。

Information technology using network and multimedia technologies have developed into creative tools that have expanded human abilities.Information technology education is popular in elementary and middle schools across China.Under such circumstances it is imperative to integrate information technology with other subjects.As an experiment-driven subject,chemistry uses the microscopic world of molecules and atoms to analyze chemical reactions in macro materials. Information technology guided by modern constructivist theory has powerful functions like multimedia integration and resource sharing,playing more important roles in chemistry classes.The writers aim at improving middle school students’ comprehensive understanding of chemistry.They have conducted research on the integrated teaching model of ＂Demonstration-based Model＂ based on the teachers’ using information technology,and ＂Interaction-based Model＂ based on the combination of the students’ self studies and the teachers’ demonstrations.The research have achieved positive results.
