高效课堂充分体现了新课改教学理念,本文以高效课堂教学模式为指导,对高中化学课程《糖类》进行了教学设计。1教材分析本节课是人教版化学选修5第四章第二节的教学内容,是在学习了烃和烃的衍生物,以及化学必修2中有机化学的知识基础上进行学习,因此应注意知识的联系。本节内容分为三部分,第一部分葡萄糖与果糖,第二部分蔗糖与麦芽糖,第三部分淀粉和纤维素,期间穿插了一些探究实验,本节知识与生活实际密切相关,也为后续高分子
Efficient classroom fully embodies the teaching concept of the new curriculum reform. In this paper, efficient classroom teaching mode as a guide, high school chemistry course “sugar” for teaching design. 1 Teaching Material Analysis This lesson is the teaching content of Chapter 2, Chapter 4 of the PEP 5, which is based on the learning of hydrocarbon and hydrocarbon derivatives and the knowledge of organic chemistry in Chemistry Compulsory 2 Pay attention to the connection of knowledge. This section is divided into three parts, the first part of glucose and fructose, the second part of the sucrose and maltose, the third part of the starch and cellulose, interspersed during some of the exploratory experiments, the knowledge of this section is closely related to life, but also for follow-up polymer
