Features: The series "Decoding Key Points—Breaking Down Difficulties with Models" is based on the "Curriculum Standards" and integrates the knowledge systems of various textbook versions. It focuses on junior and senior high school curricula and the actual needs of the junior and senior high school entrance exams (Zhongkao and Gaokao). The books are compiled by topic. The series includes a total of twenty-eight volumes covering three subjects: mathematics, physics, and chemistry for both junior and senior high schools.
A model is a concept that people are very familiar with. For example, children's toys are models of real objects, robots are models that simulate humans, and the formula for the area of a rectangle, S = ab, is a mathematical model, and so on. What are the models in this book? Simply put, they can be seen as formulas. From the perspective of middle school students' learning, establishing knowledge points into concise and scientific models (formulas) plays an important role in summarizing, memorizing, and solving problems.
This series is based on the actual needs of junior and senior high school curricula and the junior and senior high school entrance exams (Zhongkao and Gaokao). It organizes the model systems of mathematics, physics, and chemistry for junior and senior high schools, making them easy to remember and apply, and thus holds extremely high practical value in breaking down the key and difficult points of the knowledge system.
From life to mathematics, from life to physics, and from life to chemistry, applying knowledge to production and daily life, engaging in exploratory learning, and solving practical problems closely related to production and daily life are the requirements of the "Curriculum Standards" and also the key focus of the junior and senior high school entrance exams (Zhongkao and Gaokao).
Each topic in this series is treated as a separate chapter, with explanations, examples, and exercises specifically designed to illustrate the methods and techniques for using models to solve real-world problems in production and daily life. This fully reflects the "modeling" concept of the "Curriculum Standards."
