1, which is the different solution of solid geometry in the second volume of Senior Two.

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.

2. The knowledge content of the same module, version A and version B are different.

For example, the classification of four prisms and the concepts of regular prisms and regular prisms are not only given in version B, but also used in exams, but not in version A..

Main differences:

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.

Extended data

There are the following differences in the structure presentation between the two editions of textbooks:

1, each section of the A version of the textbook leads to the content of this section through the questions set in "Inquiry". These exploratory questions cover the key points and difficulties of almost every section. Before setting these inquiry questions as formal content, let students study with questions and curiosity.

2. The first edition of the textbook has a column of "Reading and Thinking" in each section, and a reading material is either placed before or after the knowledge to be learned. In the chapter of statistics, there are three reading materials, covering politics, production, advanced mathematics and so on. Among them, interesting and practical, the latter two are further supplements to the statistical knowledge learned.

3. In part 2. 1, the textbook version A has added part 2. 1.4, which is similar to the curriculum standard that "data can be collected through experiments, reading materials, designing questionnaires, etc." Meet the requirements. One version of the textbook does not introduce data collection in detail as a separate part.

4. In the correlation between variables in Section 2.3, the first section of Version A gives the impression of the correlation between two variables through a large number of examples.

In the textbook version B, the correlation between two variables is introduced by comparing the examples of differences between the two variables. This section also introduces the concept of scatter plot, which is also a difference from the A version of the textbook.
