Features: The new curriculum standards have significantly reduced the difficulty in assessing students' knowledge points. The new examination reform places greater emphasis on the process of assessing students' knowledge mastery and thinking abilities. In other words, in the college entrance and high school entrance exams, the scoring criteria do not simply evaluate the results of problem-solving but rather focus more on the standardization and completeness of the solution process, awarding points based on the steps taken. This change in the evaluation system undoubtedly presents new challenges for our teaching and preparation: How can teachers cultivate students' thinking abilities and the habit of solving problems in a standardized and complete manner? How can students learn and master standardized problem-solving methods? To meet this demand, we have organized renowned senior and advanced teachers from famous high schools across the country to write this series of "New Question" books.
The compilation basis of the series:
1. The series fully incorporates the latest achievements in curriculum and examination reforms, is based on the new curriculum standards textbook by the People's Education Press, and is synchronized with the knowledge points of the textbook, fully reflecting the spirit of the new curriculum standards.
2. It is practical and firmly follows the direction of examination question-setting and scoring principles. Based on the key, difficult, and examination points in teaching, the series has created a substantial number of new and flexible questions, rigorously selecting and analyzing classic questions from the past five years of college entrance and high school entrance exams across various provinces and cities in China. This provides teachers with a question bank for teaching and students with a model for learning and mastering standardized problem-solving methods.
3. Based on the subjects examined in the college entrance and high school entrance exams, we have first published the "Chinese Problem-Solving Dictionary," "Mathematics Problem-Solving Dictionary," "English Problem-Solving Dictionary," "Physics Problem-Solving Dictionary," "Chemistry Problem-Solving Dictionary," "Physics Experiment Problem-Solving Dictionary," and "Chemistry Experiment Problem-Solving Dictionary," covering all key subjects of the exams.
The basic features of the series:
1. Organized according to the knowledge points of the textbook, linking the knowledge system with classic question-solving formats. In terms of functionality, it reflects the characteristics of a quick-reference tool.
2. Fully absorbs the advantages of similar books, refining and innovating: whether in the design of the question pages or the selection of question types, it reflects the vibrant characteristics of the times; whether in the analysis of problem-solving approaches or the arrangement of each step, it reflects precise and targeted compilation principles.
3. A standardized, standardized, and complete problem-solving process not only accurately analyzes key, difficult, and high-frequency examination points but also enables students to learn problem-solving methods and techniques, helping them achieve: steady and accurate steps in solving problems. Even when facing difficult, flexible, or comprehensive questions, they can still score high. The "Note" section helps students avoid potential pitfalls in their thinking and problem-solving processes.
The functions and usage methods of the series:
The series, with its standardized, standardized, complete, and accurate problem-solving processes, has the quality of a good learning tool. For teachers, providing specific guidance to individual students is not difficult. However, what students truly need is systematic, comprehensive, and continuous guidance. Only by seizing this opportunity can they leverage their initiative and strengths to "learn by themselves," mastering methods, knowledge, and progress. This series can provide such a platform for both teachers and students. It is also an excellent question bank and an important teaching reference material.
For students, especially those at medium and above-average levels, improving their scores—even by 3 to 5 points—requires long-term effort. They often lose points not because they lack knowledge but because their problem-solving steps are incomplete or non-standard. "New Question" can help students enhance this ability.
For parents, it is difficult to guide children who have entered middle school, making the cultivation of their self-learning ability particularly important. "New Question" has excellent toolbook quality, and children can achieve twice the result with half the effort by reading it themselves. In fact, an excellent teaching guidebook is a powerful tool for learning. Used correctly and consistently, it not only helps students overcome many difficulties they encounter in their studies but also cultivates a lifelong learning habit and thinking method.
