Features: This series of books is designed with a step-by-step approach in its layout. Each book is divided into two parts—"Basic Concepts" and "Comprehensive Application" (high school edition as "3+X Comprehensive Application"). Each section in the "Basic Concepts" part is further divided into two columns: "Knowledge Point Analysis and Application" and "Broadening Horizons."
The "Knowledge Point Analysis and Application" focuses on thoroughly and clearly explaining the basic knowledge, helping students clarify the knowledge framework and solidify their understanding, laying a solid foundation for improving their performance to a new level. The "Broadening Horizons" column is designed for students to "reach even higher" after firmly grasping the basic knowledge. As the ancients said: "Give a man a fish, and he eats for a day; teach a man to fish, and he eats for a lifetime." This is also the purpose of writing this series.
As the latest offering from Longmen Bookstore, Longmen Special Topics has the following features:
1. Specialization First
This series consists of 72 books, and you can choose the most practical and beneficial ones according to your needs.
2. Detailed and Comprehensive Explanations
Since each book focuses on a specific topic, the explanations of knowledge points are naturally more detailed.
3. Time-Saving and Efficiency
Due to the concentrated nature of the "topic" content, each book has relatively fewer pages, allowing students to target their learning and achieve a thorough understanding of a whole block of knowledge in a shorter time.
4. Limited Scope
It combines "synchronization" with "asynchronicity" with the textbook. "Synchronization" means that all the knowledge points covered in the textbook are included in this series, each in its own book. "Asynchronicity" means that the books are not necessarily arranged in the same order as the textbook chapters but rather group a knowledge block into a system for.
5. Clear Priorities
Each book lists the proportion of points covered in recent years' college entrance exams, allowing students to weigh priorities and improve efficiency.
Another feature of this series is its full reflection of the "lightening the load" spirit. The fundamental goal of "lightening the load" is to cultivate a new generation of versatile talents with knowledge and skills, which is an important aspect of implementing quality education. In terms of teaching, only by improving teaching quality and efficiency can we truly achieve the purpose of reducing students' burden. The books in this series highlight key points, focus on learning and practice, and greatly benefit students in improving their relative efficiency in learning a specific topic. This is also the key focus.
Longmen Special Topics (Junior High School Mathematics) consists of 12 books, covering all knowledge points in the junior high school mathematics curriculum. They are divided into different units based on grade-specific and cognitive characteristics for in-depth analysis, explanation, and practice, emphasizing key and difficult points, revealing problem-solving methods, and exploring breakthroughs and quality development. Each book is divided into two major sections: "Basic Concepts" and "Comprehensive Adaptation." The "Basic Concepts" section follows the textbook system, focusing on thorough and detailed explanations of basic knowledge to help readers clarify the knowledge framework and solidify their understanding, laying a solid foundation for improving performance. The "Comprehensive Adaptation" section stays at the forefront of educational development, focusing on the exploration of thought methods and problem-solving skills permeating junior high school mathematics, highlighting the cultivation and guidance of innovative awareness. It selects unique examples and exercises to guide students in enhancing their innovative and creative qualities.
In the writing of each book, the new curriculum standards issued by the state are followed, with a strong emphasis on developing hands-on and thinking skills, fostering exploratory thinking, and ensuring that each book reflects a combination of foundation and innovation. Each book embodies the following features in its writing:
1. Specialization as the Core
The books are divided into different topics based on knowledge blocks, with explanations progressing from simple to complex, from surface to depth, in a step-by-step manner. Reading one book can help you fully grasp "a landscape" of junior high school mathematics.
2. Comprehensive and Detailed Explanations
Each book strives to thoroughly explain every knowledge point of a topic, integrating both foundation and advancement. It not only builds a foundation but also cultivates abilities and broadens horizons.
3. Strong Targeting
Each reader can choose the appropriate book to read, reflecting an economical and practical approach.
4. Combining Learning and Exams
Each chapter predicts the proportion of knowledge points covered in the junior high school entrance exams and selects the latest exam question types for classification and explanation at the end of each chapter. This helps readers weigh priorities, allocate learning time reasonably, and understand exam trends.
