Findings:
This questionnaire was distributed to junior three students, and 30 questionnaires were distributed and 30 were recovered. The valid questionnaire is 100%. Questionnaires were distributed to 20 teachers, 20 questionnaires were distributed, 20 questionnaires were collected, and the effective questionnaire was 100%.
Through the investigation, the following problems were found:
1. When students answer questions, explain the idea of solving problems or describe the learning process, they make mistakes in using words and the language is inaccurate.
2. The students who spoke used too many languages to express complex topics, which were repetitive and some even out of order, making the expression chaotic.
3. In class, some students speak very actively. If they are allowed to speak, the language will be verbose, the answers will be vague, and the mathematical language will lack simplicity and simplification.
4. In class, most students can fully express simple questions or knowledge acquisition process. Once the process is complex or comprehensive, more students will have incomplete and intermittent language when expressing their thoughts, and they cannot fully express what they think, get, experience and express incompletely.
In the future teaching, we should pay attention to the following points:
1. We should always pay attention to the language expressed by students in class, correct mistakes at any time, and ensure the accuracy of students' language.
2. Guide students to think positively and evaluate each other. Through positive evaluation, students can experience the happiness of success and improve their enthusiasm for expression. Through this conscious training, students will gradually speak in an orderly way, which also reflects the order of his thinking, and students' thinking ability will be developed.
3. Strengthen guidance, pay attention to students' language expression, and the language should not be wordy, short and powerful, so as to cultivate students' conciseness in mathematics language.
4. Ask students to think before speaking when expressing mathematical language, and express it in complete sentences.
