Features: Huanggang materials are everywhere, and Huanggang Middle School is the only one! Authenticated by Huanggang Middle School, this is the first public publication of the internal workbook! Warm-up before class, homework during class; homework after class, online for the college entrance exam! Founded in 1904, Huanggang Middle School of Hubei Province was a key middle school in Hubei Province in 1953, awarded the title of "Advanced Unit in the National Education System" in 1986, and ranked as "Advanced Unit in National Spiritual Civilization Construction" in 2002.
Huanggang Middle School upholds the educational philosophy of "human-centered, virtue-based," forming the distinctive feature of "comprehensive and specialized" education and exploring the teaching style of "seeking truth, refinement, uniqueness, and innovation." Her achievements in college entrance exams and competitions are the inevitable results of her long-term implementation of quality education, and only one aspect of her abundant teaching results.
When it comes to cultivating students, what magic formula does Huanggang Middle School have? What function does it have to turn sand into a tower? What ability does it have to turn stone into gold? These are questions I often hear. If you think Huanggang Middle School always follows the of the college entrance exam and passively takes the test, that is wrong. Huanggang Middle School does not advocate rote memorization or passive problem-solving. If she has any exceptional qualities, it lies in her ability to fully understand the intentions of the test setters and deeply grasp their underlying principles, becoming a leader rather than a blind follower.
Huanggang Middle School does not oppose teachers diving into the sea of problems but strongly advocates students stepping out of it. It opposes students doing mechanical, simple, repetitive, and monotonous problems but requires them to do some necessary ones. We advocate students solving flexible and diverse problems with broad applications, allowing them to enrich their knowledge, develop their abilities, and enhance their qualities in the process of problem-solving.
If there is anything else Huanggang Middle School has achieved success in, it is that while cultivating and nurturing a large number of outstanding students, it has also forged its teaching team, creating renowned teachers in Hubei Province. These teachers possess deep scientific and cultural literacy, innovative educational concepts, unique teaching styles, artistic skills, and fruitful teaching results.
To showcase the talents of Huanggang Middle School teachers and share their teaching achievements, we have organized first-line core teachers from the school to meticulously plan and compile three series of books: "Huanggang Middle School Workbook," "Huanggang Middle School Exam Papers," and "Huanggang Middle School 2006 College Entrance Exam First and Second Round Training Questions."
The "Huanggang Middle School Workbook" series is based on the "Teaching Syllabus" and "Exam Syllabus," highlighting the role of "homework" in the process of students forming learning ability, problem-solving ability, and exam-taking ability. It reflects the inevitable connection between Huanggang Middle School students' brilliant performance in various exams and their rigorous daily practice.
This series has been carefully designed in its format, featuring four major sections—pre-class warm-up, in-class homework, after-class homework, and (senior/intermediate) college entrance exam online—to reinforce training and improve abilities. It has the following features:
1. Appropriate exercise positioning: In the arrangement of exercises, this series focuses on consolidating and gradually improving the knowledge points, test points, question types, and methods. The positioning of the series is to help students upgrade their problem-solving skills through progressive exercises in ability-based, open-ended, applied, and comprehensive formats.
2. Moderate difficulty gradient: The ratio of basic, intermediate, and difficult questions in this series is 6:3:1, suitable for the use of most middle schools. Most questions are labeled with A, B, or C to indicate their difficulty levels, ensuring appropriate and clear requirements.
3. Detailed solution hints: The answers at the back of the book are appropriately detailed, with more thorough solutions provided for difficult questions. It is particularly worth mentioning that the well-timed hints sometimes play a pivotal role.
This series emphasizes the originality and quality of the authors' exercises, with rigorous review and proofreading at every stage, striving to become a unique gem in the educational supplement market.
