Features: The series "Decoding Key Points—Breaking Down Difficulties with Models" is based on the "Curriculum Standards," integrates the knowledge systems of various textbook versions, and focuses on the practicalities of junior and senior high school curricula as well as the junior and senior high school exams. It is 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 simulating 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 practicalities of junior and senior high school curricula and the junior and senior high school exams, presenting a model system for mathematics, physics, and chemistry for both junior and senior high schools. It is designed to be easy to remember and apply, offering extremely high practical value in breaking down the key and difficult points of the knowledge system. From life into mathematics, from life into physics, and from life through 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 key examination content for the junior and senior high school exams.
Each topic in this series is treated as a separate chapter, explaining, providing examples, and offering exercises to specifically 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." Leading-edge topics, modeling problem-solving—excellent and varied!
