Homework reading for textbook

 From a teacher's perspective, the examples provided emphasize the role of examining how textbooks connect students to mathematics, their peers, teachers, and the world. At the same time, textbooks have a certain structure, and the form of language and images in textbooks influence students' mathematical understanding. Also, considering the students in the class, if there are ELL students in the class, then the textbook is a good resource for them to learn some specialized mathematical language. Teachers may use other words to explain specific definitions in order to make it easier for students to understand, so it is easier for students to associate those easy-to-understand words with specialized mathematical vocabulary.

From my own point of view as a student, I would not use the textbook too much, but it is a good resource for me to prepare and review. I would use the examples in the textbook to preview what we were going to learn and to review if I forgot them afterward. Through reading this article I have found that indeed when I see specific language in a textbook I will recall a specific situation that it introduces.

Perceptions of textbook use and role change:

Regardless of how updated textbooks are, textbooks are a resource that can be referred to for maths learning. Textbooks are constantly evolving, the applications to the real world may change, the variety of examples may change, and there will be plenty of additional information and hands-on activities afterwards. What I have learned through my short practicum is that my SA will choose examples from different versions of textbooks to present through knowledge of the students' classes. I also think that textbooks are a resource for us and we can use them flexibly.
