Summary

This textbook series is a Dalian municipal local textbook compiled under the organization of the Dalian Municipal Education Bureau and the Dalian Education College (Teaching and Research Office). In response to the current coexistence of multiple editions of textbooks under the new curriculum standards, the series takes the new curriculum standards as its general outline, integrates the major domestic editions of new-curriculum-standard textbooks, stays closely aligned with the college entrance examination and serves it, and is written according to the synchronized plan of daily teaching. Using this textbook can replace both the textbook and all supplementary materials, thereby reducing students' burden while improving learning quality, and it is well received by students and teachers. The senior high school mathematics volumes of this series (9 in total) have been used in trial form as lecture handouts in two middle schools in Dalian for one year and have won high praise. Accordingly, the Dalian Municipal Education Bureau decided to formally publish this textbook and, starting in autumn 2008, to trial it in more schools in the city, gradually extending it citywide thereafter. In 2008, 5,000 sets were sold on an exclusive basis.

Editor's review

This book is a locally integrated textbook for the senior high school mathematics elective 2-1 stage. It continues the approach of taking the new curriculum standards as the outline and integrating the content of major domestic textbook editions, organized according to the daily teaching schedule, striving to combine textbook and supplementary material in one volume. Elective 2-1 usually covers main content such as logical terminology, conic sections, and space vectors. The value of this book lies in gathering the formulations of multiple editions onto a single main line of study, reducing the burden on students of switching among different textbooks; the examples and exercises are arranged around the college entrance examination requirements, facilitating synchronous consolidation. The regional teaching-research background gives the knowledge review and method summary a fairly systematic structure, suitable for classroom follow-up. When reading, it is recommended to first master the concepts and the reasoning process of the examples, then complete the accompanying exercises; especially for content with heavy computation such as conic sections and space vectors, pay attention to standardizing steps and organizing mistakes. Self-learners should consult the official textbook for comparison, and where editions differ, defer to the curriculum standards and the teacher's explanations.

Who it's for

A good fit for

High school sophomores using the Dalian local textbook and currently studying elective 2-1 content
Students who need to integrate knowledge from multiple editions synchronously and reduce switching among supplementary materials
Middle school mathematics teachers who want to unify teaching progress and exercise arrangements
Lesson planners who want to review the main line of elective 2-1 against multiple textbook editions

Not a good fit for

Students who need to study page by page against one specific textbook edition
Lower-grade students who have not yet finished the compulsory content and lack a solid foundation
Students who only want competition-level enrichment or university preparatory content

Reading tips

Advance section by section according to classroom progress, first understanding concepts and example reasoning, then completing the accompanying exercises.
For conic sections and space vectors, pay attention to written steps and check standard formatting against the answers after finishing problems.
At the end of each chapter, organize a method list and types of mistakes to avoid repeating the same errors.
Read in comparison with the textbook edition you use; where editions differ, ask the teacher to confirm, with the curriculum standards as the authority.

FAQ

What does elective 2-1 mainly cover?

According to general curriculum knowledge, elective 2-1 usually includes common logical terminology, conic sections and equations, and space vectors and solid geometry. This book integrates the major textbook editions according to the new curriculum standards; the specific chapter arrangement is subject to the table of contents and the school's teaching plan. It is recommended to confirm the study order against the textbook.

How does this book connect with the compulsory 2 volume?

Both books belong to the same set of locally integrated textbooks and are divided into volumes according to the daily teaching schedule. Generally, the compulsory stage should be completed before entering elective 2-1. It is recommended to use them in the school's teaching order, and when studying elective content, regularly review the foundations of functions, equations, and geometry from the compulsory stage to avoid gaps in knowledge.

What should I do if I find the conic sections part difficult?

Conic sections involve heavy computation and are highly comprehensive. It is recommended to first master the definitions and standard equations, then practice common problem types, and pay attention to writing steps and checking. After doing problems, organize mistakes by problem type and summarize general methods such as setting points and setting lines. If it is still difficult, slow down, review the reasoning of each textbook example, and then move on to comprehensive practice.

Is it suitable for senior year review?

This book is positioned as synchronous learning material, written according to the daily teaching plan and closely tied to the college entrance examination requirements to build a foundation. During senior year comprehensive review, it can be used to review main knowledge and typical methods, but it should not be the only review material; it is recommended to combine it with thematic practice and comprehensive papers to strengthen weak areas.

About the author

杨光宇 Author

Yang Guangyu is an author for whom very limited public information is available. The verifiable information about him centers mainly on supplementary high school mathematics books that he has contributed to. Two of his works are included in the database, namely High School Mathematics: Compulsory 2 and High School Mathematics: Elective 2-1, both falling under the exam category. This suggests that his writing is closely tied to synchronized training for the high school mathematics curriculum and to exam preparation. Judging from the existing titles, Yang Guangyu's editorial work follows the knowledge structure of high school mathematics textbooks, covering both compulsory and elective modules and serving students' practical needs in daily study and review. Because public records of his biography and professional background are lacking, little more can be said about his personal experience, and any assessment of his works' influence must remain limited to their subject positioning. Overall, Yang Guangyu can be regarded as an author involved in compiling high school mathematics supplementary materials, whose contribution lies chiefly in supporting curriculum standards and helping students consolidate their mathematical foundations and improve their problem-solving skills.
