What is the role of teaching materials in teaching and how to make good use of them?

Reading textbooks can be said to be the basis and source of normal classroom teaching.

As we all know, no matter how good the textbook is, it can only provide an idea and a design scheme for teaching and learning according to the general situation, and it is impossible to fully adapt to every school, let alone every student in every class.

Generally speaking, reading materials mainly include the following four aspects:

First, the writing ideas of reading textbooks;

The second is to understand the arrangement intention of teaching content;

Third, the context of reading textbooks;

The fourth is to read the "moral" of the textbook.

How to use teaching materials effectively

The use of flexible teaching materials means that on the basis of truly understanding the teaching materials, respecting the prototype and examples of the teaching materials, and according to the learning situation of students in this class and the actual needs of students at different levels, teachers dig deep into the connotation of the teaching materials, appropriately supplement, expand and extend the teaching materials, and give full play to the functions of the teaching materials.

First of all, we should pay attention to lighting up the details of the textbook.

For example, teaching "A conical wheat pile with a bottom radius of 1.5 m and a height of 2 m, if the wheat weighs 700 kg per cubic meter, how much does this pile weigh?" When I asked questions, I caught the detail that "wheat weighs 700 kilograms per cubic meter", which lit up the students' thinking. Teaching experience tells us that students are easily confused about the learning content of this unit, especially the understanding of "bottom area, lateral area, surface area and volume". Teachers should not only let students deeply understand the connotation of concepts, but also pay attention to capturing teaching details.

Secondly, we should pay attention to supplementary teaching materials.

Teachers who have listened to or watched Dou Guimei's class will certainly feel the same way. She added three contents to the lesson "It's not worth visiting the garden": chalk words, body language and a related piece of music. Writing beautiful chalk words immediately won students' impression points and students' good feelings for the teacher; Proper body language can not only deepen students' understanding of the text, stimulate students' interest in learning, but also enliven the classroom atmosphere; Coupled with a nice piece of music, while relaxing and enjoying the art, the impression of words naturally deepens.
