| The teacher's classroom presentation behavior is a bridge between the teaching content and the students.It is a key factor for students to understand and obtain the teaching content,which affects the classroom teaching effect and teaching quality.However,in the classroom teaching process,there are still some problems in teachers' presenting behavior,such as single presenting behavior and uncoordinated presenting behavior.Therefore,in order to gain a deeper understanding of the teacher's classroom presentation behavior,this study takes the teacher's classroom presentation behavior as the research content,compares the similarities and differences between the pre-vocational,novice and expert teachers' classroom presentation behaviors.And then based on the research conclusions and reasons,puts forward suggestions and strategies for pre-service teachers and novice teachers to improve classroom presentation behavior.In this study,teachers' classroom presentations were divided into narrative presentations,blackboard presentations,audio-visual presentations and action presentations.According to the relevant classroom observation scale and division dimension,the "Primary School Teacher Presentation Behavior Observation Scale" is compiled.First of all,this study uses the classroom observation method to collect data,and organizes the classroom observations and cases;secondly,through the comparative research method to analyze the data and cases,and then draws conclusions;thirdly,based on the conclusions and classroom observations,analyze the reasons,and puts forward suggestions for pre-service and novice teachers.This study used Spss to analyze the data and combine it with classroom observations to draw conclusions.Among them,the similarities are manifested in the following two aspects: First,in the board presentation,pre-service,novice and expert teachers can flexibly use the board presentation to achieve their own teaching purposes.Second,in the audio-visual presentations,pre-service,novice and expert teachers use slide presentation content and use audio-assisted teaching less.The differences are manifested in the following three aspects: First,there are significant differences in pre-service,novice and expert teachers in narrative presentation,and pre-service teachers are significantly lower than novice teachers and expert teachers.Second,in terms of blackboard presentation,thefrequency of writing errors for novice teachers is higher than that of pre-service teachers and expert teachers.Third,in terms of action presentation,there are significant differences between pre-service,novice and expert teachers,and pre-service teachers are significantly lower than novice teachers.Finally,in order to help pre-service and novice teachers improve their classroom presentation behavior and teaching efficiency,this study proposes relevant strategies to pre-service and novice teachers according to the dimensions of choosing classroom presentation behavior and using classroom presentation behavior.Specifically,pre-service teachers and novice teachers should learn the theory of classroom presentation,construct subject knowledge system,discover and form teaching style,so as to scientifically select classroom presentation behavior.In addition,they should also strengthen the training of specific presentation methods,rationally coordinate various presentation methods,so as to rationally use classroom presentation behavior. |
