Study On The Design And Evaluation Of Micro-course Of Problem Solving

The rapid development of information technology has changed the way people learn and acquire knowledge,the development mode of explosive development of information that the cyber source is fragmented,so in order to reduce the cognitive load of learning must explore new content delivery and learning mode,which can promote students' learning and sharing of learning resources.As a new learning form,micro course can satisfy learners' learning requirements of fragmentation.Therefore,it has been vigorously promoted and supported after its advent.The development of micro class has also experienced the stage of resource composition,teaching process and network course,and now it has been basically mature.But it is undeniable that also appeared in the development of micro course many problems can not be ignored,based on the research of the micro class status and practical application,through comparative analysis of the existing problems that the micro class can through micro class design and micro teaching evaluation research.On the design of micro lesson,the design and development of the form of micro course is still teaching teaching mode similar to formal classroom based,but can leave the classroom after watching,and other aspects of classroom teaching immediate difference is small,it can not really realize the value and significance of micro lesson.In addition,in terms of teaching methods,it is basically knowledge imparting,neglecting to cultivate students' problem consciousness and develop students' ability to solve problems.In twenty-first Century,especially after the presentation of the core literacy of Chinese students,our education and training strategy is obviously adjusted to train problem-solving ability and innovative talents.From the research literature of micro lesson,although in recent years,the design of problem solving related micro lesson has gradually entered the eyes of scholars.However,the research on this aspect is still in its infancy,and it is not mature enough.In the evaluation of micro class aspect,in the micro class as a teaching resource perspective to construct micro class evaluation index system has been relatively complete,especially with the various types of micro class competition related evaluation index system in practice has been further improved and perfected.However,the micro class also belongs to the category of the curriculum.In the past evaluation,there is not too much research on the evaluation of the micro class in this category.Micro class as teaching resources can be the premise of learners use love must be recognized on the requirements of its quality,micro class and ordinary class curriculum teachingas the only teaching well to get recognition of learners,so in the micro teaching in the course of evaluation is an important link,and the teaching design and micro the course is closely related.Professor Li Jia Hou put forward the "expert review of the micro lesson resources of cloud education platform for intelligent education" : "the teaching design and teaching evaluation of micro lesson should be parallel and cannot be separated".The research on this aspect has already begun to arouse the attention of the researchers,but there is still a need for further research.In view of the above problems,the author starts with the idea of "asking questions,analyzing and putting forward ideas Design--designing application cases--teaching evaluation of relevant teaching cases".Firstly,the related literatures at home and abroad are studied,and the problems existing in the development of micro lesson are put forward.And put forward the solution of the design of the problem solving class micro class.On the basis of the clear solution,the design model and the teaching design model of the problem solving class micro class are put forward.On this basis,the mathematics stage of junior high school is taken as an example to design two micro classes in three grades and carry out the corresponding education experiments.Finally,through the data collected and the effectiveness of the micro class teaching effect,the design of the problem solving class micro class is evaluated and summarized from the perspective of teachers,students and designers.This study concludes that the problem solving class micro class is helpful to the improvement of students' ability to solve problems.In the aspect of teaching evaluation,teachers and students are evaluated through questionnaires,test results and interviews.Through the analysis of relevant data,the researcher carried out a comprehensive teaching evaluation of the problem solving micro class from the perspective of the designer.The problem solving micro class teaching and micro lecture as a whole have been highly evaluated and recognized.
