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 Zhongkao (senior high school graduation exam) and Gaokao (university entrance exam), with topics organized into chapters. It includes a total of twenty-eight volumes covering three subjects: mathematics, physics, and chemistry in both junior and senior high school.
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 Zhongkao and Gaokao, presenting a model system for mathematics, physics, and chemistry in junior and senior high school. It is designed to be easy to remember and apply, making it highly valuable for breaking down the key and difficult points of the knowledge system. Moving from life into mathematics, from life into physics, and from life through chemistry, applying knowledge to production and daily life, and engaging in inquiry-based learning to solve practical problems closely related to production and life—this is the requirement of the "Curriculum Standards" and also a key focus of the Zhongkao and Gaokao.
Each topic in this series is presented in 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" philosophy of the "Curriculum Standards." Leading-edge topics, modeling-based problem-solving—excellent and exciting!
