化学实验不仅是学生获取直观信息、认识化学世界的窗口,而且还是帮助学生认识规律、形成概念、理解巩固化学知识、提高化学科学素养的重要途径。当前,化学实验教学正面临着更新教学理念、实现现代实验教学手段,以及增加实验的自主探究性等多重任务,其重要性已越来越被广大化学教师所共识。本文结合新课标对化学实验的要求及教学现状,谈谈如何利用学案导学提高化学实验的有效性。
Chemistry experiments are not only a window for students to acquire visual information and recognize the chemistry world, but also to help students understand the law, form concepts and understand important ways to consolidate chemical knowledge and improve chemistry literacy. At present, the teaching of chemistry experiment is facing the task of renewing the teaching idea, realizing the modern experimental teaching method and increasing the independent inquiry of the experiment, whose importance has been increasingly recognized by the majority of chemistry teachers. In this paper, the new curriculum requirements of chemical experiments and teaching status, talk about how to use case study guide to improve the effectiveness of chemical experiments.
