Innovative homework, after-class homework, classroom homework, and preview homework! Founded in 1928, Qidong High School of Jiangsu Province is one of the first national model high schools, located in Qidong City, known as "North Shanghai" with its riverside and coastal charm in the Yangtze River Delta. After eighty years of, it has become a first-class modern school in China with international influence, and its name has spread far and wide. Qidong High School currently has 99 teaching classes and over 5,600 students. It boasts a strong faculty, including 1 Ph.D., 24 master's degree holders, 3 provincial young and middle-aged experts, nearly 100 senior and advanced-level teachers, as well as a large number of provincial and municipal subject leaders and core teachers. The school is equipped with first-class laboratories, libraries, gyms, art halls, observatories, science museums, multimedia, and distance education networks, meeting students' needs for reading, training, and personalized development. In recent years, the school has continuously strengthened exchanges and cooperation with other provinces and internationally, establishing 4 new branches. Over the years, the school has taken "developing individual strengths, promoting comprehensive development, and laying a foundation for lifelong student growth" as its educational philosophy, actively implementing quality education with remarkable achievements. Through long-term educational practice, Qidong High School has gradually formed a distinctive educational style: "human-centered, moral education first, solidifying foundations, and fostering individuality"; a guiding principle: "everything for the students, for all students, and for the sake of all students"; and a magic formula: "scientific education and research-driven school development." The school is advancing along the educational approach of "comprehensive education and cultivating specialized talents," making steady progress and further enhancing its reputation. A group of outstanding teachers and subject leaders at Qidong High School, in addition to their teaching duties, diligently strengthen educational research and the study of middle and high school examination questions, establishing their own question bank and achieving excellent teaching results. To sincerely express gratitude to sister schools across the country and meet the wishes of teachers and students, at the kind invitation of the renowned and authoritative scientific publisher (Longmen Bookstore), our school has organized dozens of senior and advanced-level teachers and gold-medal coaches from the frontline of teaching. Combining years of teaching experience, especially since the "3X" new college entrance examination reform and the new curriculum reform, we have meticulously planned and compiled this scientific and practical "Qidong High School Homework Series." This is the first formal collaboration between Qidong High School and a national-level publisher, and we hereby specially authorize Longmen Bookstore to exclusively use our registered "Qidong High School" trademark for publication. The "Qidong High School Homework Series" jointly launched by Qidong High School and Longmen Bookstore reflects our school's teaching practices and experience in nurturing top students and addressing learning gaps. It is authentic and we believe it will be highly favored by readers.
This edition of the "Qidong High School Homework Series" has undergone careful revision. The revision is based on the new "Teaching Syllabus," "Examination Guidelines," and "New Curriculum Standards." The design of the series showcases innovation, including sub-sections such as [Preview Homework], [Classroom Homework], [After-Class Homework], and [Innovative Homework]. During the revision, we also boldly innovated in the creation of homework questions, reflecting a fresh sense of the times, with a focus on new question intent, content structure, scenario creation, question-setting methods, and open-ended exploration. This aims to align with the trends of the new round of curriculum, teaching, and examination reforms, making it more suitable for regions, schools, and students of different levels. It not only helps solidify foundational knowledge but also enhances learning and exam-taking skills.
During the revision, we fully emphasized the following guiding principles and features:
1. Layered and Progressive Question Structure: The questions are designed to fully consider the teaching realities in underdeveloped regions in central and western China and the diverse needs of teachers and students regarding "questions." Each question is labeled with hollow letters (A, B, C) at the beginning to indicate its approximate difficulty level, facilitating differentiated instruction and improving the efficiency of homework practice.
2. Practical and Effective Lesson Design: The greatest difference from traditional teaching aids lies in designing homework by lesson, for synchronous classroom use, making it practical, effective, and highly operable. It integrates thinking into practice, focusing on solving the problems of "what to practice" and "how to practice" in each lesson.
3. Detailed and Standardized Explanations: The answers are thoroughly analyzed, highlighting key knowledge points and basic methods, and striving to teach problem-solving techniques. This addresses the questions of "how to solve" and "how to think about solving" the problems, making it widely applicable. Additionally, each homework assignment is clearly marked with time limits and scoring standards, allowing students to "teach themselves" and thus more effectively improve their practice quality. Therefore, this series can also be considered a student ability test book.
4. Innovative and Extraordinary Educational Philosophy: The revision fully reflects the requirements of the new round of teaching reforms, embodying the educational philosophy and concepts of the new curriculum. It showcases extraordinary thinking. The selection of questions follows the principle of "originality and classics," with a focus on strengthening the development and research of "ability-based, open-ended, applied, and comprehensive" questions. Each subject's homework series includes a certain number of newly created original questions by the authors.
From the perspective of the "three exams" (syllabus, key points, and actual exam questions), this series of "Qidong High School Homework" examines and analyzes the questions, providing guidance and insights into solving methods and techniques. It serves as an excellent supplementary material for students in junior and senior high school, guiding them in learning, practice, and exams.
During the writing and revision of this series, despite our careful attention to every chapter and question, and despite repeated reviews over several months, some errors and omissions may still exist. We sincerely welcome feedback from readers to allow us to make timely corrections.
