Features: This set of exercises deliberately pursues four characteristics: comprehensive, lightweight, accurate, and innovative. The arrival of the new millennium calls for a large number of highly qualified innovative talents; the emergence of such talents largely depends on the of quality education. Currently, high and junior high school students not only hope to have a set of new teaching materials that adapt to the development of the times but also crave a set of exercise books that embody the spirit of new education reform and are synchronized with the new teaching materials. Such exercise books should not increase students' academic burden but should enhance their ability to comprehensively apply the knowledge they have learned in a relatively short period.
All materials come from the most famous high schools in the country—Huanggang High School in Hubei Province. Experienced teachers who have taught for many years and possess rich teaching experience, including key teachers responsible for teaching and question-setting, have participated in the overall planning and question design of this exercise book. Based on an in-depth study of the new teaching materials and in line with new ideas and the actual needs of teaching in various regions, they have compiled this series of innovation ability training books. The chief editor is Chen Mingxing, a special-grade teacher and subject leader at Huanggang High School.
The guiding principles for writing this series of books are as follows:
1. Based on the current teaching syllabus and new teaching materials, it comprehensively covers all knowledge and ability requirements in a certain field. Training and testing are conducted from multiple angles, levels, and all-round perspectives, forming a scientific, rigorous, and complete training system. The purpose is to improve students' mastery of basic knowledge and skills in related courses.
2. Adhering to the teaching syllabus but not confined to it, a certain number of applied questions are developed. Most of these questions align with hot and focal topics in social life, guiding students to pay attention to the future and fate of the world, humanity, and the environment. The purpose is to enhance students' ability to comprehensively apply the knowledge they have learned to analyze and solve practical problems.
3. The core of the "3+X" college entrance examination reform is to strengthen the assessment of students' innovative and practical abilities. Therefore, the compilers of this book have studied and developed a certain number of open-ended questions. The purpose is to help students develop a sense of subjectivity and lay a foundation for cultivating their innovative spirit.
4. The design of the exercises follows the principle of "step-by-step progress and continuous improvement," avoiding repetitive questions on the same knowledge points at the same level and discarding overly difficult, broad, or deep questions. The overall difficulty is appropriate, with equal emphasis on objective and subjective questions.
5. The questions are designed in a standardized manner, with novel question types and vivid materials. During the writing process, efforts are made to include new situational questions related to industrial and agricultural production, daily life, and new technologies, fully highlighting the practicality and practicality of the questions. The purpose is to stimulate students' interest in training and improve the effectiveness of testing.
This set of exercises is the best choice for students' self-assessment, parents' guidance, teachers' evaluation, and school-wide exams.
