随着计算机在教育教学上的应用日趋广泛,笔者努力钻研在化学课堂上使用计算机辅助教学,激发学生学习化学的兴趣,提高主动学习的积极性,优化化学课堂教学,提高教学效率和质量。一、利用计算机的模拟功能计算机的模拟功能可使抽象内容形象化,静止内容动感化,为学生创造生动、活泼、直观、有趣的教学条件。1.模拟展示微观粒子的结构和运动。化学是研究分子、原子及核外电子等微粒运动的科学,而微观粒子的运动又是用肉眼所看不到的,用手摸不着的。常规教学通常用挂图或投影片、模型等媒体示意,由于其僵化、固定而缺乏直观的效果。计算机电教媒体变小为大,变静为动,把微观
With the increasing use of computers in education and teaching, the author endeavored to study the use of computer-assisted instruction in chemistry classrooms to stimulate students’ interest in learning chemistry, enhance the enthusiasm of active learning, optimize chemistry classroom teaching and improve teaching efficiency and quality. First, the use of computer simulation function Simulation of computer functions can visualize abstract content, static content dynamic, students create a vivid, lively, intuitive and interesting teaching conditions. 1. Simulation shows the structure and movement of microscopic particles. Chemistry is a science that studies the movement of particles such as molecules, atoms, and extranuclear electrons, and the movement of microscopic particles is invisible to the naked eye. Conventional teaching is usually shown on a wall chart or slide, model and other media, due to its rigid, fixed and lack of visual effects. Computer audio-visual media becomes smaller, changeable to move, the micro
