《化学与技术》模块是高中化学的一个选修模块,该模块涉及很多物理、化学原理及利用物理、化学原理解决生产中的技术问题。这些原理很抽象,对于初次接触这些内容的高中生来说,无疑是学习中的障碍和难点。所以,如何把原理讲清楚、易于理解,是教学中关键的一环。通过几轮的课堂教学,我发现以剖析教材为着眼点的问题驱动教学将有助于学生对抽象原理的领悟和理解。

The “Chemistry and Technology” module is an optional module for high school chemistry. The module involves many physical and chemical principles and uses physical and chemical principles to solve technical problems in production. These principles are very abstract and are undoubtedly obstacles and difficulties for high school students who are new to these contents. Therefore, how to make the principle clear and easy to understand is a key part of teaching. Through several rounds of classroom teaching, I found that driving teaching with the focus on analyzing textbooks will help students understand and understand abstract principles.
