Features: The series "Decoding Key Points - Model Cracking Difficulties" 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. 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.
Model is a very familiar concept to people. 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 considered 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 and memorizing knowledge points and solving problems. Based on the actual needs of junior and senior high school curricula and the junior and senior high school entrance exams, this series 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 cracking the key and difficult points of the knowledge system.
From life to mathematics, from life to physics, from life through chemistry, applying knowledge to production and life, conducting exploratory learning, and solving practical problems closely related to production and life are the requirements of the "Curriculum Standards" and also the key examination content in the junior and senior high school entrance exams. Each topic in this series is set as a separate chapter, explaining through explanations, examples, and exercises the methods and skills of using models to solve practical problems in production and life, fully reflecting the "modeling" concept of the "Curriculum Standards."
Pioneering topics, modeling problem-solving, and a spectacular display of brilliance!
