Research On The Optimization Design Of Theorem Micro-course Based On 5E Teaching Mode

The ?Standards on Senior High School Mathematics Curriculum(2017 Edition)?pointed out “The teachers should lay emphasis on the deep integration of information technology and mathematics curriculum to realize the effect that was difficult to be achieved by traditional teaching means.”As the product of the mathematics curriculum deeply integrated by information technology,the research theme on mathematics micro-courses' design and application corresponded to the requirements of the era development and met the actual demands of current mathematics education with relatively strong application value for decision maker,researcher and practitioner,and the optimized design on micro-course,itself,could be called as superiorly educational resource or product,which had unique application value in improving high school mathematics education.As an important constituent of high school mathematics education,the theorem education provided soil for cultivating students' logical reasoning,visual imagination,mathematical abstraction and other core attainments by relying on its rigorous and precise mathematics thought.In actual educating process,the achievements sourced from micro-courses were rich but the quality was not so good at all times.So how to utilize the reasonable principles and strategies to optimize the micro-course was an issue that educational researcher should take care of.Based on the above considerations,this paper had optimized the theorem micro-course based on the following teaching design principles under the guidance of 5E teaching mode,including the setting strategy and information packaging principle,spatial proximity principle,time approaching principle,consistency principle,dual channel principle,redundancy principle and other principles during educating process,and analyzed the optimization effect of the theorem micro-course by educating experiment,questionnaire survey,student interview as well asevaluation of first-line teacher,in order to provide certain theoretical and practical reference for the research and education practice in the field of mathematics education technology optimization.In theory,this paper collected related research results at both home and abroad and also defined the involved core concepts by combing related literature.Based on actual demands and implementation significance of high school theorem micro-course optimization,this paper summarized and generalized the educating design principle and setting strategy of the high school theorem micro-course optimization during teaching process according to theoretical speculation and experience.In practice,the optimization of the mathematics theorem of some high school mathematics is optimized,and the optimization effect of the high school theorem micro-course is evaluated through teaching experiments.And supplemental questionnaire,student interview and first-line teacher evaluation were also conducted,in order to discuss the effect of students' understanding on mathematics learning,problem solving,emotional attitude,study style as well as thought improvement by the optimized theorem micro-course.Research results showed,the optimized high school theorem micro-course by the way of applying educating design principle and the setting strategy during teaching process was helpful to improve students' memory and understanding level of the knowledge,the ability to solve problem and thinking level,and additionally helpful to improve students' learning interest and change their learning styles.However,a longer period of time for the long-term process of improving such thinking level,changing learning style and developing learning interest was also needed to accumulate,therefore,it was necessary to consistently insist on,constantly adjust and continuously optimize the educating plan.At the same time,it was needed to pay attention on giving students more time to think and control the geometric occurrence points during micro-course design process,so as to avoid weakening students' independent thinking ability and developing lazy thinking habits.
