Research On The Micro-Lecture's Design And Application Of Mathematical Concept In Middle School Based On Articulate Storyline 3

Information technology has injected new vitality into the modern development of mathematics education in " Internet +" era.Micro-lecture is short and exquisite,which fits students' personalized learning.Therefore,micro-lecture has become the most concerned form in the development of digital mathematics teaching resources.At present,the number of micro-lecture of mathematical concept is small and unicast micro-lecture is the main part.However,students can't interact with the content through unicast micro-lecture.Therefore,this paper puts forward a series of ideas,principles and strategies of interactive micro-lecture design from the perspective of technological innovation and the interaction demand between students and learning content.In addition,this paper applies the example "inverse proportional function" to the students' independent learning,in order to provide certain theoretical and practical reference for the design and application of interactive micro-lecture.The following is the main work of this the research.In terms of theoretical research,this paper defines the relevant concepts,summarizes the relevant research on mathematical micro-lecture at home and abroad,and analyzes the main problems existing in the current design of mathematical microlecture.Secondly,it introduces the theoretical basis of designing mathematical concept interactive micro-lecture.Finally,it discusses the basic idea,principle and strategy of the design of the interactive micro-lecture of junior middle school mathematics concept.In the aspect of practical research,the interactive micro-lecture "inverse proportional function" is designed and compared with the unicast micro-lecture using recorded PPT.This paper examines the effectiveness of interactive micro-lecture in students' independent learning through experiments and surveys.The study results of students under three different independent learning strategies of mathematics textbook,unicast micro-lecture and interactive micro-lecture were compared and analyzed.Furthermore,questionnaire and interview were used to understand the influence of the use of micro-lecture on the learning process of students,so as to obtain the experimental results combining qualitative and quantitative methods.The results show that in the self-directed learning mode,interactive micro-lecture is more beneficial to the improvement of students' academic performance than textbooks.Although compared with unicast micro-lecture,there is no significant difference in students' performance when learning with interactive micro-lecture.Interactive micro-lecture has a more positive impact on students' understanding of mathematical concepts,learning methods and attitudes,and brings better learning experience.
