Features: The series "Exam Point Decoding—Model Cracking Key and Difficult Points" 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 exams, with topics organized into specialized chapters. The series includes a total of twenty-eight volumes covering three subjects: mathematics, physics, and chemistry for junior and senior high schools.
Model is a very familiar concept to people. 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 exams, presenting a model system for mathematics, physics, and chemistry that is easy to remember and apply, making it highly valuable for 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 through exploratory learning and solving practical problems closely related to production and life are the requirements of the "Curriculum Standards" and also key assessment content in the junior and senior high school exams. 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, fully reflecting the "modeling" concept of the "Curriculum Standards." Leading-edge topics, modeling problem-solving—exquisite and varied!
