1. Textbook writing time: It takes a long time to write and modify the textbook, and the content of the math exam will be adjusted according to the actual situation. When compiling textbooks, the problem of including parameters is not common, and it is not considered as an important content, so it is not included in the senior one math book.
2. Ability training and assessment requirements: The purpose of the examination is to assess what knowledge and skills students have mastered and encourage students to use what they have learned to solve practical problems. Although the questions with parameters are not introduced in the initial stage, the introduction of such questions can promote students' creative thinking and flexible use of knowledge.
3. Comprehensive Application and Outward Bound Training: The math test will involve different levels and types of questions, and test students' ability to understand and apply knowledge. Questions with parameters can help students combine what they have learned with the actual situation and cultivate their ability to solve problems in complex environments.
