1, version A and version B are distinguished by "region", but the same region uses a version of the textbook.
2, version B is more difficult, mainly for science students. B version pays attention to the exercise of skills and thinking, and has strong logical thinking, so it is more difficult than A version, and some problems can only be solved after careful thinking, which is more ingenious and concise. Version B pays attention to being more practical, and the questions are more open and novel.
3. The editors of version A and version B are different. The biggest difference is the difference in cultivating mathematical thinking and mathematical ability, so some contents are different.
4. The arrangement of class capacity is slightly different, which may lead to a slightly different learning order, and the emphasis and details of each chapter are different; The following two pictures are a comparative study of the necessary statistical contents of version A and version B of the new curriculum standard textbook for senior high school mathematics.
Version a:
Version b:
In a word, version B is more difficult than version A and more suitable for science students.
Extended data:
For version A textbook, teachers all think it is an excellent textbook, and generally attach great importance to the teaching of statistics. As far as textbook B is concerned, teachers generally think that textbook B attaches great importance to the use of computers, which is also a big difference from other textbooks.
A teacher who once participated in the Liaoning Textbook Examination and Approval Committee said that the B version of textbooks is mainly introduced to relatively advanced areas, mainly reflected in the use of computers, and other textbooks may not be so distinctive.
Teachers in the trial area of version A textbook all think that the statistical content design in the textbook is "ok" or "very in place", and no other opinions are put forward.
For the textbook version B, some teachers with senior teaching experience think that statistics has not changed much from the perspective of knowledge. They think the most important thing is random sampling, and estimate the population with samples.
The content of the first section has already appeared in the previous college entrance examination, so there are many topics to do at ordinary times. The content of the second section is mainly to draw frequency histogram, and there are many exercises in this area at ordinary times.
The content of the third section has not appeared in the college entrance examination before, and I don't think it is very important. Many teachers only skim through this section when teaching. As far as the teaching situation of version B is concerned, teachers also take the college entrance examination as the premise and do not start with the essence of statistics.
