A Study On Science Teaching Design In Primary School Based On TPACK Theory

Since the 21st century,with the continuous integration of information technologies and education,information technologies have been being used in elementary and middle schools in classroom teaching.For the science subjects,the use of information technology has changed the traditional teaching model,making the learning of scientific knowledge rich and colorful,and improving the teaching effect.However,unable to effective integration between information technology and science courses is still a general problem.To date,in the field of science classroom teaching research,investigations on the integration of information technology and science courses are relatively small.TPACK theory explains the connection between teaching technology,teaching method and teaching content,and how to effectively integrate information technology with course teaching.The introduction of TPACK can effectively solve the problems in the integration process,which provides new ideas for elementary science teachers to effectively integrate information technology and science courses.Therefore,how to design science classroom teaching in primary school based on TPACK theory will be particularly important.This article first summarizes the current research status of the TPACK theory at home and abroad,and then attempts to construct a design model for primary school science teaching based on the TPACK theory.Furthermore,a lesson on "Ubiquitous Energy" is selected as a specific science teaching design example.The implementation of the science class has achieved very good teaching results.The paper is divided into the following six parts:The first part :Expounds the research background of the paper,summarizes the domestic and foreign research status about TPACK,and discusses the research content,research method,research purpose and significance,and research ideas in detail.The second part:Explains the theoretical basis and related concepts of the thesis,mainly including TPACK theory,constructivist theory,project-based learning theory and learning by doing theory.The third part: A primary school science teaching design model is constructed based on the TPACK theory,and then the element analysis stage,the integration stage,the teaching case design stage,the implementation stage and the evaluation stage of the model are interpreted in detail.Finally,the principles of teaching design based on the model are expounded,including the principles of integrity,student-centered,situational and technical mapping.The fourth part: A specific teaching case design of "Ubiquitous Energy" is carried out based on the science teaching design model and teaching design principles above.including: basic element analysis of teaching,integration stage analysis,specific teaching case design and teaching evaluation design.The fifth part: The concrete science teaching design based on TPACK theory is implemented and evaluated from teachers,students and myself.The sixth part:Summarizes and prospects this research.Through the above research,it is found that: Firstly,TPACK theory provides a new idea for primary school science teaching design,and plays a guiding role in the integrated technology of primary school science teaching design.Secondly,the design model of primary school science teaching based on TPACK theory plays a positive role in improving the teaching effect of primary school science course,and the model is operable and effective.
