| The rapid development and popularization of computer technology have new requirements for students' information literacy and higher requirements for teachers' teaching ideas.This research is based on the research background of "relying on information technology to create an information-based teaching environment,promote the reform of teaching ideas,teaching models and teaching contents,promote the in-depth and wide application of information technology in daily teaching,and meet the needs of cultivating high-quality talents in the information age" proposed by the Ministry of education in the "13th five year plan of educational informatization".Based on the requirements of cultivating students' core quality of physics discipline put forward in the physics curriculum standard of ordinary high school(2017),combined with the current situation of a large number of information technology assisted physics teaching in the information age,the question of "how to improve the effective combination of physics teaching and 'information' and cultivate talents to adapt to the information age" was taken as the starting point for research.In the use of information teaching aids,two problems have been found: : on the one hand,professional programming modeling software requires teachers and students to have a certain code programming foundation,which is difficult to popularize.On the other hand,students do not know why the simulation experiment products made directly using these software are presented in this way,which is difficult to be convinced.Scratch has the advantages of simple operation and strong interaction.It can not only visualize the abstract model,but also let students experience the process of establishing the model.Therefore,discussing the applicability of scratch software and physical model construction teaching and exploring the application strategy of scratch software assisted physical model construction teaching has certain practical significance.This paper is divided into the following four parts:1.The first and second chapters demonstrate the feasibility of applying scratch to physical modeling teaching from three aspects: the relationship between model construction ability and computational thinking ability,the implementation steps of physical modeling teaching and many advantages of applying scratch to physical modeling teaching.2.In the third chapter,combined with physics teaching in middle school,the author studies the application scope and application strategy of scratch,and gives the teaching steps of physical modeling suitable for scratch software.3.The fourth chapter is to understand the level of physical modeling ability and computational thinking ability of the research object through the investigation method,and whether the students have the knowledge base to carry out the physical modeling teaching of scratch,so as to carry out the appropriate teaching design according to the students' existing knowledge and ability level.At the same time,through horizontal comparison,explore the relationship between model construction ability and computational thinking ability.4.The fifth and sixth chapters use the action research method and take the section of "the law of projectile motion" as an example to carry out the physical modeling teaching practice of applying scratch,and test the teaching effect of this teaching practice from the students' adaptability to scratch and the achievement of teaching objectives through questionnaires and test questions,so as to test the effectiveness of the application of scratch in physics classroom.The results show that the physical model teaching combined with scratch software can help students improve their model construction ability,which is mainly reflected in improving students' learning interest,improving students' modeling consciousness and improving students' understanding of physical concepts and laws. |
