Data expansion:
First, the difference between the new textbook and the old textbook
1, integrating knowledge points:
Compared with the original textbook, the knowledge points and system of the new textbook are more concentrated, and the classification between modules is clear, which is convenient for students to understand and practice.
2, the difficulty distinction is obvious:
After the reform, the textbook defines the compulsory volumes 1 and 2 as basic exercises, so that students can complete the basic mathematics knowledge exercises in senior high school in the compulsory stage and help students complete the connection and transformation between junior high school and senior high school from the first year of senior high school. At the same time, the pressure of students gradually shifted to the elective part.
In the future teaching, senior one is likely to complete the compulsory study of one or two, and senior two will begin to take elective courses. In this way, from the second year of high school, the difficulty gradually increased.
3, pay attention to basic exercises and applications:
As can be seen from the textbook, the textbook writers attach importance to the examination of basic knowledge and the infiltration of mathematical culture. Each chapter is followed by similar practical application or related exploration of mathematical culture, which shows that the application ability of mathematical knowledge is a trend in the future.
Second, why change textbooks?
On the one hand, the content and form of PEP textbooks can't meet the needs of modern classroom teaching. With the development of economy and social progress, people's living standards are constantly improving, and the requirements for education are getting higher and higher. However, the textbooks currently used by People's Education Press can hardly meet people's requirements for modern classroom teaching.
For example, in the traditional classroom, teachers are often omniscient "experts", while students are obedient "containers". Such a classroom atmosphere is not conducive to students' thinking, solving problems and developing creativity.
On the other hand, there are a lot of mistakes and irrationalities in the textbook of PEP. In recent years, the relevant departments have audited the textbooks published by People's Education Publishing House and found that there are a lot of mistakes and irrationalities.
For example, many problems in history. Some historical events are untrue, the background of the times is inaccurate, the introduction of historical figures is not objective and fair enough, and the causal relationship between historical events is unilaterally ignored or distorted. This kind of problem not only affects students' correct understanding of history, but also misleads them.
Therefore, in order to enable students to adapt to the increasingly complex and changing society, the education department should speed up the reform of the teaching materials of People's Education Publishing House to make them more suitable for the actual situation of current classroom teaching and help students better adapt to the future society.
