Features: The series "Decoding Key Points - Model Cracking Difficulties" 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 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 practicalities of junior and senior high school curricula and the junior and senior high school exams. It organizes the model systems of mathematics, physics, and chemistry for junior and senior high schools, making them easy to remember and apply, and holds extremely high practical value in cracking 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, conducting exploratory learning, and solving practical problems closely related to production and daily life are the requirements of the "Curriculum Standards" and also the key examination content in the junior and senior high school exams.
Each topic in this series is set as a separate chapter, explaining, exemplifying, and practicing methods and techniques for using models to solve real-world problems in production and daily life, fully reflecting the "modeling" philosophy of the "Curriculum Standards." Leading-edge topics, modeling problem-solving—excellent and exciting!
