The Case Development And Application Of Geometer’s Sketchpad In Middle School Physics Course

Physics is the foundation of the natural sciences,telling us where to go in the future,it has created a ladder to open up the future,with a sense of orientation and source.Informationization is a great trend of world economic and social development at present.Information technology with multimedia and network technology as the core has become a creative tool to expand human capabilities.In physics teaching,how to combine traditional teaching media with new multimedia computer technology is a hot issue that teachers pay close attention to.As a teaching software promoted by the National computer Education Research Center in primary and middle schools,the practicability of geometric drawing board is self-evident.Based on the efforts to improve the core literacy of physics,the thesis is based on the "vigorously promoting the universal application of information technology in the teaching process" stipulated by the Ministry of Education in the outline of basic Education Curriculum Reform(trial)in 2001.To promote the integration of information technology and subject curricula,with a view to "encouraging the rational use of information technology in physics teaching" in 2011 by the Ministry of Education in the Physics Curriculum Standard for compulsory Education,In 2017,the Ministry of Education pointed out in the General High School Physics Curriculum Standard,"through the integration of diverse teaching methods and information technology" as a guide.Using the methods of literature analysis,interview,case study and so on,aiming at the case development and application of geometry drawing board in middle school physics course,the following five problems are discussed emphatically: the first part is the introduction part.This paper mainly describes the research background,purpose and significance of the paper,as well as the status quo of domestic research.The research methods,technical routes and innovations are described in detail.The innovation of this paper lies in the close combination of geometry drawing board and teaching material.On the level of how to use geometry drawing board to make courseware,this paper makes concrete analysis and demonstration through typical teaching design cases.Deeply excavating how to set up the physical model matching with teaching in order to help students to set up cognitive structure and to promote the establishment of logical system of physics discipline;In the second part,according to the cognitive learning theory of modern pedagogy and psychology,the emergence and development,function and operationalcharacteristics of geometric sketchpad are clarified by combing the relevant theories of the integration of geometric sketchpad and physics curriculum.The construction of learning theory and the transfer theory of cognitive structure reveal the consistency and feasibility of case development and application of geometry drawing board in middle school physics curriculum.The third part expounds the concrete application of geometric drawing board in creating physical situation,breaking through fixed thinking and dynamic physical problems.The fourth part reveals how to organically combine and develop the concrete cases through geometry drawing board in middle school physics course,and the fifth part gives the concrete teaching suggestions,as well as the reflection and prospect of this research.
