Research On Speech Act In Teacher-Student Interaction In High-quality Mathematics Courses Of High School Based On IFIAS

As the representative of higher teaching level,high quality class has a demonstration and leading role in teaching.Speech act interaction is the most important way in teaching activities,accounting for about 80%of teaching behaviors,and can be clearly expressed and objectively recorded.It is an effective way to promote the professional development of young teachers and consolidate the basic skills of young teachers in controlling the classroom,and it has certain guiding significance for young teachers to study the common characteristics of the speech act interaction between teachers and students in high-quality class with the teaching video case as the research model.From the perspective of the heterogeneity of the same course,this study used the general class video analysis software to conduct IFIAS coding statistics on 9 high-quality courses of "one teacher with one excellent course and one lesson with one teacher".Firstly,the interactive characteristics of speech acts between teachers and students in concept class,principle class and exercise class are analyzed and compared respectively from five dimensions:teaching mode,teaching style,teachers and students' emotion,teachers and students' speech structure,and teachers and students'question-and-answer;Then the overall summary and analysis of the 9 high-quality lessons;Finally,the differences in the interaction characteristics of speech acts between teachers and students in excellent courses are discussed from the perspectives of gender,the level of excellent courses and the type of topics.Overall,the samples of the high quality classes in verbal interaction between teachers and students all have distinguishing feature each,with the following characteristics:(1)The teacher has a good verbal structure and gives students more time to share,communicate and think;As for emotional characteristics of teachers and students,teachers are good at using positive interaction to mobilize students' emotions,and the classroom atmosphere is harmonious;In terms of teaching style and characteristics,teachers are inclined to direct control,good at adopting students'opinions,and will positively feedback students' emotions.(2)The characteristics of questions and answers between teachers and students are poor.Teachers are not good at asking questions and students are reluctant to express their opinions in class.The teaching mode is poor,and the teacher's classroom innovation is not enough or more limited to the question-and-answer training inquiry mode.(3)From the perspective of gender differences between male and female teachers,female teachers have a looser classroom structure and are more amiable.They are more apt to adopt students' views and give students more blank time.Male teachers are more inclined to let students discuss with their peers in their respective roles,and are more likely to ask open questions,so the teacher-student relationship is more diversified.(4)From the perspective of the difference in the level of excellent courses,excellent teachers'questions are more focused,whose words are more concise and easy to understand,and their answers are standard.It is easier for students to answer the questions,and excellent teachers are more inclined to innovative inquiry teaching mode.(5)From the perspective of class types,teachers have better control over concept class,use more computer technology,and pay more attention to cultivating students' sense of cooperation.The innovation of this research is as follows:(1)The general class video analysis software is used to code the interaction characteristics of speech acts between teachers and students in high-quality mathematics class;(2)Qualitative analysis is used to conduct multiple case studies on the interaction between teachers and students in the same class and in different classes;(3)Analyze and summarize the interaction characteristics of speech acts between teachers and students in high-quality classes,providiy guidance for the classroom speech acts interaction of young teachers.The disadvantages are as follows:(1)Small sample size;(2)Under the same subject,there are fewer courses containing ministerial excellence,provincial excellence and municipal excellence,which makes the sample have a certain locality;(3)The coding and data processing process has a certain subjectivity;(4)Some factors of the interaction of speech acts between teachers and students are neglected,such as region,age,and evaluation criteria of excellent courses;(5)Any study of speech interaction behavior without teaching content has a certain situational nature.
