The rapid development of educational information,"micro-classes" are widely used in middle school physics teaching,not only because micro-classes have short teaching time,small teaching capacity,strong pertinence of knowledge points,convenient use,etc.,but also because micro-class resources constitute a scene It can be used as a resource to assist middle school physics teaching by effectively applying micro-classes to physics teaching,which can improve students’ learning motivation."Education Informatization 2.0" also proposes to actively promote "Internet +education" to build a learning society in which everyone can learn,learn everywhere,and learn from time to time.As a digital teaching resource,micro-classes respond to the call of the times.Therefore,it has attracted the attention of teachers and students.The ARCS motivation model proposed by American psychologist John.M.keller focuses on students’ attention,relevance,self-confidence,and satisfaction in the learning process.This study introduces the ARCS motivation model as the theoretical basis for the design of micro-classes.Taking the "Joule’s Law" of junior high school physics as an example,the design of micro-classes based on this model and its application effects are studied.First,through the questionnaire survey method,the current situation of junior high school physics teachers’ design and application of micro-classes and the current situation of students’ learning motivation of physics micro-videos are investigated.After data analysis,combined with the literature research method,it is proposed to build a micro-class based on the ARCS motivation model.The basic principles of the course design model have constructed and optimized a micro-course design model based on ARCS motivation theory including front-end analysis,subject analysis and evaluation system,and designed four models based on attention,relevance,self-confidence and satisfaction.A micro-course design template for motivational strategies.Secondly,taking the content of junior high school physics-related courses as an example,the micro-class design based on the ARCS motivation model is made,and the pre-study,experimental and exercise micro-classes are made,and the experimental research method is used to conduct micro-class teaching experiments in middle schools.Thirdly,through the interview method,to understand the teacher’s evaluation of the optimized micro-class design model based on the ARCS motivation model,and get feedback.Finally,it investigates the learning motivation of students’ physics micro-videos again,analyzes and compares the improvement of students’ physics learning motivation,and compares and analyzes the results of students before and after learning micro-classes,and completes the evaluation of the learning effect of applying the micro-class model.Draw conclusions through relevant literature review,experimental teaching and data analysis:First,this study systematically sorts out the current status of micro-courses and ARCS motivation models at home and abroad,as well as the connotation,motivation design and research basis of micro-classes and ARCS motivation models.Second,research and analysis show that current teachers lack a certain theoretical understanding in the design of micro-classes.In terms of the production technology of micro-classes,they lack professional and systematic guidance.Students have low motivation to learn physics micro-classes.They are guided by the proposed model design principles.Next,the constructed and optimized design micro-class model and template based on the ARCS motivation model provide suggestions and guidance for teachers to design micro-classes.Third,after the teaching experiment of the micro-course design model based on the ARCS motivation model,the analysis shows that the micro-course design and teaching based on the ARCS motivation model significantly improve students ’ physics learning motivation and physical learning performance.Therefore,the ARCS motivation model The micro-class design model has certain theoretical and practical guiding significance for the design and production of middle school physics micro-classes. |
