在高中化学教学中,不仅要让学生获得必要的知识与技能,还要培养学生的素养。要丰富学生的学科素养,就要获得一定的分析问题与解决问题的能力。但是,化学知识中有很多抽象的问题难以理解,需要通过建模来让复杂的问题简单化。建模能让抽象的化学知识简单化,让无形的知识变得有形。这就需要我们在教学实践中渗透建模思想,让抽象的知识变得生动形象,从而让学生便于理解与接受。一、让学生感受化学模型的构建过程
Chemistry teaching in high school, not only to allow students to acquire the necessary knowledge and skills, but also develop students’ literacy. To enrich the academic quality of students, we must obtain some ability to analyze and solve problems. However, there are many abstract problems in chemical knowledge that are difficult to understand and need to be modeled to simplify complicated problems. Modeling simplifies abstract chemical knowledge and makes intangible knowledge tangible. This requires us to infiltrate the idea of modeling in teaching practice, so that the abstract knowledge becomes vivid, so that students can easily understand and accept. First, let students feel the chemical model construction process
