Research On The Design And Practice Of Elementary School "Science" Micro-course Based On ADDIE Model

Education teaching in the context of interest rate has had a profound impact on the traditional education teaching field.As a new product of the information background,micro lesson has been highly valued by many experts and scholars.Although the micro-course is "micro",but the content is complete,it has also gained the favor of more and more learners and gradually entered into the daily curriculum teaching.micro class resources are not rich,micro class quality is also uneven,which has brought a lot of trouble to educators.Based on this,the design and practice of the purpose of this study is to explore the micro lesson in primary school science curriculum,the classical ADDIE model and primary school "science" micro class together closely,expecting to bring interested in engaging in this work colleagues to more thinking and enlightenment.In the early stage of this study,the literature research method was used to sort out the micro lesson and ADDIE model.it was found that there is relatively little research on the design and practice of ADDIE model and primary school "science" micro lesson.the preliminary analysis of the research work is carried out with the help of questionnaire survey and interview method,and its needs and feasibility are demonstrated.In the middle of the study,the design process of "science" microcourse in primary school under the ADDIE model and the five phase design principles should be followed.According to the design process and principles,the case of "science" microcourse in primary school was developed.In the later stage of the study,we applied micro lesson cases to primary school's "scientific" teaching practice,and applied the survey method,Z test method,and listened to the feedback of teachers,and carried out the evaluation of the application effect after class.Under the ADDIE model,primary school "science" micro lesson design can reflect every step in teaching,inspire students' interest in learning,and provide a new idea for how to achieve efficient teaching.
