Version A is a traditional geometric method that uses axiomatic theorem as an auxiliary line to solve solid geometry problems. Version B is a new content, that is, following the knowledge of plane vector in Volume One, using the method and concept of space vector to solve solid geometric problems, and algebraic calculation to solve geometric problems.
The standard answer to the big question of solid geometry in the college entrance examination will include the solutions of these two methods. Version B is mainly used in some big cities or areas with curriculum reform, such as some schools in Beijing.
The difference between version A and version B of mathematics taught by senior high school students;
1, version A and version B are distinguished by "region", that is, one version of textbooks is generally used in the same region.
2. The overall difficulty of version B is higher than that of version A, and it is more suitable for science students.
3. The editing of version A and version B is different, resulting in different contents.
4. There are two pictures, which are a comparative study of the required statistical contents of version A and version B of the new curriculum standard textbook for senior high school mathematics.
Version a:
Version b:

A summary of comparative analysis of statistical contents in two editions of textbooks;
The two versions of 1 were written from different perspectives:
The first edition of the textbook advocates the teaching method of "problem situation", which allows students to learn and discover knowledge in thinking, greatly changing the previous "indoctrination" teaching method. In the compilation of teaching materials, we should pay more attention to the psychological characteristics and cognitive characteristics of high school students, and pay attention to the interest and affinity of teaching materials.
2. Statistical differences in content structure.
Generally speaking, the A version of the textbook advocates active and inquiry learning methods in both content and form, which is also the embodiment of the new curriculum concept.
In the setting of each class, the problem situation set in the "inquiry" is introduced into the classroom, so as to give full play to the initiative of students and make the learning process of students a "re-creation" process under the guidance of teachers. At the same time, the design of statistical content of version A takes into account the cognitive characteristics of senior high school students.
On the other hand, the B version of the textbook pays attention to the integration of information technology and mathematics curriculum, which is another embodiment of the new curriculum concept. In this part of statistics, the integration with information technology is particularly obvious. Data are collected and analyzed by computer, and sample mean, sample standard deviation, regression equation and so on are calculated by function calculator.
3. Differences in the expression of statistical content.
Version A pays more attention to the coherence between contents, and the presentation of contents is more organized and clear. Introduce the topic into the problem situation-"inquiry", and explain the statistical methods and ideas with more cases in real life.
The textbook version B pays more attention to the connection with other knowledge such as algorithms, which is the embodiment of the new curriculum's understanding of the concept of "double bases" advancing with the times.
The content of algorithm has been added to the senior high school mathematics curriculum, and the basic knowledge of data processing and statistics has been taken as the new basic knowledge and skills of mathematics, all of which meet the needs of the development of the information age. Paying attention to algorithm teaching is also the biggest feature of the B version of the textbook.
