With the deepening of national basic education curriculum reform, the implementation scope of the "Curriculum Standards" for compulsory education is gradually expanding, and new educational concepts are being accepted by more and more educators and the public. China's basic education is undergoing profound changes. The core of this transformation is a shift in role for teachers and a transformation in learning methods for students. In line with this spirit and to adapt to the further development of curriculum reform, we made significant revisions for the second edition after extensively soliciting opinions from experts, teachers, students, and parents. The book has been revised in accordance with the principle of being derived from but superior to the new textbooks, providing comprehensive explanations, analysis, and guidance on its knowledge points and competency requirements. Each section includes the following sections: Syllabus and Exam Requirements, Textbook Explanation, Method Guidance, and Consolidation Exercises. Among these, "Textbook Explanation" is the key section of each chapter. It provides detailed explanations and analyses of the knowledge points of each chapter based on the new textbooks, focusing on the expansion and cultivation of knowledge and skills, as well as the revelation and summary of patterns and methods. Through typical conventional problems, innovative open-ended problems, and practical application problems, it allows students to explore and experience the knowledge points of the new textbooks, and is designed according to the following three points:
1. Comprehensive analysis of typical examples, with the following four sections:
① Thought Guidance: Provides insights into problem-solving strategies.
② Solution: Offers standardized answers based on the solution plan.
③ Error Analysis: Points out common mistakes, identifies their causes, and provides error prevention tips.
④ Remarks: Summarizes key points in the problem-solving process and analyzes the critical aspects of problem-solving techniques. The purpose of these sections is to open students' minds and focus on summarizing patterns and methods.
2. Attempt to solve related problems (or modified problems). Proposes questions related to or similar to the above typical problems from different angles, allowing students to achieve a thorough understanding through imitation during practice.
3. Each typical problem targets a specific knowledge point in the textbook, aiming to provide students with practical experience and understanding of the relevant content through the exploration of examples.
During the writing process, the author strives to explain all the content of the textbooks, with a large amount of information, achieving precision in explanation, analysis, and selection. The explanations are thorough and in-depth, with clear and detailed distinctions, and the analytical methods are novel, distinctive, and unconventional.
The "Very Special Explanations" series offers detailed explanations, thorough analysis, clear structure, logical organization, rich content, and strong practicality and guidance in mastering key points, difficulties, and doubts of the textbooks, as well as in cultivating and improving understanding, analysis, judgment, comprehension, thinking, and problem-solving skills. It is another successful work by Longman Center after the "Middle School 1+1" series, and the two can be considered sister series. While the former focuses on explaining and analyzing the textbooks, the latter emphasizes the explanation and testing of key and difficult problems. They are both an integral whole and complement each other.
Learning the "Curriculum Standards" and updating educational concepts is an ongoing process; the implementation of curriculum reform also requires continuous exploration and accumulation. The revision of this book is a concrete implementation of learning the "Curriculum Standards" and reforming teaching content and methods. We hope that our efforts can bring practical and effective help to the teaching activities of teachers and students, and we also look forward to the criticism and guidance from educators and experts.
