Problem-driven Information Technology Teaching Micro-video Design And Application Research

In the context of the vigorous development of educational informatization,micro video,as a short video resource in line with the characteristics of information fragmentation,has gradually evolved into an important auxiliary tool for teachers' teaching and students' learning,leading the upsurge of "micro video" in the field of education.There are many problems that can not be ignored in the development process of micro video,which has experienced three stages before gradually becoming mature.Through combing the relevant literature of micro video and problem driving,this study believes that it can be started from two aspects: micro video design and the combination of micro video and problem driving.At present,most of the micro video forms in China are still classroom recorded clips for the purpose of knowledge transfer.In addition to being able to watch them repeatedly at any time,they are not different from traditional classroom teaching in essence,and do not give full play to the value of micro video teaching.According to the national requirements for the cultivation of new talents,teaching in the form of micro video is still lack of students' problem awareness and ability training.Although in recent years,scholars began to pay attention to the design and development of micro video based on problem driven and achieved some results,the research in this area is still not mature enough.Therefore,this study focuses on problem driven.Taking the information technology course of Grade 7 as an example,this paper studies the design and application of classroom teaching micro video with different problem difficulties.This study combs and summarizes the relevant literature at home and abroad to further clarify the importance of problem driven teaching micro video to students' learning.Using the methods of questionnaire survey and educational experiment,based on constructivism theory,recent development zone theory,bloom goal classification theory and micro learning theory,this paper deeply analyzes the use effect of problem driven micro video in the field of information technology teaching,and selects the seventh grade students of a middle school in Tianjin as the experimental research object,Explore the use of problem driven micro video in teaching and its role in promoting students' problem awareness,thinking,interest level and achievement at different knowledge levels.The results show that the problem driven micro video is helpful to develop students' problem awareness and critical thinking,improve students' enthusiasm and initiative,and improve students with different knowledge levels.At the same time,this study also provides a theoretical reference for the application of problem driven micro video in information technology teaching.
