如何制作优秀微课? 一、微课 1、微课定义 微课是指基于教学设计思想,使用多媒体技术在五至十分钟以内 就一个知识点进行针对性讲解、模拟一对一教学情景的一段视音频。 这些知识点,可以是教材解读、题型精讲、考点归纳;也可以是
生学习的成就感,激发他们学习的兴趣。这样既做到了尊重 学生们的人格,也因为分层次教学方法的使用,大大提高了农 村中学语文课堂教学效率。 五、积极践行新课改理念,努力提高自身素质 语文是一门基础性学科,也是一门工具性学科。因此,语
浅谈小学语文课堂教学的改革 ◆张 忠 ( 河北省承德高新区冯营子镇中心校崔梨沟小学) 课堂教学应该是各种样式、各种方法,都在竞争,都在开放,这才是大好局面。只要它能开放出特色来,它就有生命。一堂成功的
31 课堂教学是传授知识、培养能力、实施素 质教育的主渠道。要提高语文课堂教学质量, 适应素质教育的要求,就要彻底改革单纯的教 师“教”学生“学”、教师“讲”学生“听” 的传统教学模式,就要优化课堂结构改革。那
30 ◎ 姚 澄 用玩具车玩转原电池,让课堂实验更加灵动 摘 要 为了让学生爱上实验,更爱上化学,以沪科版化学教材中的“铜锌原电池”为例,阐述 如何以玩具车为载体,引导学生在一系列实验中揭秘原电池的工作原理,展开自主探索发现的学
