Construction And Implementation Of The "Staged Think-alouds" Activity In High School Physics

The teaching of exercises is the main way of knowledge application and the important link of the students' scientific thinking ability training.However,there is still a phenomenon that teachers give few opportunities to communicate and interact with students.In the teaching of exercises,with the “Think-Alouds” activity carried out,the implicit thinking is made explicit by the students' "saying",and the students' scientific thinking ability can be improved.At present,there is a lack of pertinence in the research of content and process of the“Think-Alouds”activity in academic circles.Therefore,this paper attempts to construct the training method of the activity by dividing into stages in the process,into levels in the content.This paper explores current condition and existing problems in the implementation of“Think-Alouds” activity from the perspectives of students and teachers by means of questionnaire survey and interview.Aiming at the problems in the investigation and combining with the actual situation of students.This paper constructs the activity flow of“staged Think-Aloulds” activity to primary stage,intermediate stage and advanced stage,and expounds the teaching objectives and operational principles of different stage.Combined with the teaching practice of educational practice,gives the relevant teaching cases and records in different stages,and organizes the experimental class and the control class to carry out the experimental research through the method of experimental research.After a semester of practice of “ staged Think-Alouds” activity,it is found that “ staged Think-Alouds” activity improves the enthusiasm of students to participate in classroom teaching,makes students' ability of analysis and expression progress well,and improves students' scientific thinking ability to a certain extent.By comparing and analyzing the students' physical achievement by the way of pre-test and post-test,“ staged Think-Alouds”activity also has a positive effect on the students' academic achievement.
