Research On The Design And Recording Strategies Of Middle School Mathematics Micro-lecture

"Internet + Mathematics Education" has become a hot topic in the current study of education in mathematics,and the technology of mathematics education has become a good tool to reform the education in traditional mathematics.General High School Mathematics Curriculum Standard(2017 editions)requires "focusing on the deep integration of information technology and mathematics courses and improving the effectiveness of teaching”.Perhaps mathematics micro-lecture is one of the best tools for improving traditional teaching and meeting the curriculum standards.Although micro-lecture is relatively common,the good and the bad are intermingled.Therefore,how to design and optimize mathematics micro-lecture has become an urgent issue to be studied.This thesis probes into the aspects of theory and practice.In theoretical research,through the combination of experience summary and theoretical speculation,firstly,the relevant literature on micro-lecture concepts,research on the overview of the present status of micro-lecture,relevant research on micro-lecture application and current research on micro-lecture design and recording are collated.Secondly,the basic theory of designing the middle school mathematics micro-lecture is discussed.Furthermore,the strategies of micro-lecture teaching design and micro-lecture recording are discussed emphatically.Among them,the strategies of micro-lecture teaching design can be divided into six parts: student analysis,knowledge analysis,design goal,design pattern,design method and design scheme.The strategies of micro-lecture recording are also divided into six parts: language strategy,explanation strategy,questioning strategy,feedback strategy,presentation strategy,and editing strategy.Finally,the micro class of mathematics concept,mathematics theorem,mathematics formula,and mathematics problem-solving are discussed in detail based on Freidenthal's educational thoughts,mathematics' multi-representation learning theory,and Pollyanna's mathematical problem-solving ideas.In practical research,through the combination of action research and investigation research,firstly,different theories and strategies were applied to design different types of micro-lecture,and questionnaires and case interviews were conducted to analyze the impact of mathematics micro-lecture on students' mathematics learning.Subsequently,further investigations were conducted for middle school students,normal school students,and first-line experts to compare and analyze the value of mathematical micro-course design strategies.The research results demonstrate that mathematics micro-lecture based on strategy design has a positive impact on the students' knowledge understanding,emotional attitudes,and learning methods.There are significant differences between the original and optimized versions of the micro lessons,of which the optimized version one is dominant.Hence,the majority of first-line teachers have a positive attitude towards micro-lecture.
