Research On The Characteristics Of High School Information Technology Teaching Based On Video Lesson Analysis

With the gradual deepening of the integration of information technology and teaching,using technology to promote the professional development of teachers is increasingly favored by education researchers.Observing and analyzing the classroom teaching videos can not only help teachers to learn and reflect on their own,but also improve the professional quality of teachers.The information technology course in the high school stage is of special significance to the learner's information literacy training.Therefore,the observation and analysis of the high school information technology course can not only help students develop their information technology literacy and ability,but also help teachers improve their technical literacy.This study takes advantage of the Nvivo software and uses the existing classroom observation framework and video coding analysis method to carry out the following main work on the excellent high school information technology course on the "One Teacher,One Excellent Class" which is a classroom teaching resource website:First,the research and design of high school information technology video class teaching features.The author mainly carried out two work,which is the construction of the teaching analysis framework of the high school information technology course and the design of the dimension observation table.Second,the analysis of the characteristics of high school information technology video class teaching.The author uses Nvivo software to analyze the macroscopic and micro level of 30 classroom recorded samples.The macro level refers to the analysis and classification of video teaching examples by S-T analysis.The micro level refers to the use of Nvivo software to analyze the teaching content,teaching behavior and teaching media of video lesson.Third,the research summary.In this section,the researcher summarizes the data results,and draw a summary of the teaching characteristics of the high school information technology course.This study takes the classroom recording of 30 high-quality high school information technology courses on the website of “One Teacher and One Excellent Course” as the research object,and uses Nvivo software to encode the design,countnodes and analyse data of 30 research objects,and finally came to the following conclusions:The teaching mode of high school information technology video lessons is diverse,and the choice of teaching mode is related to the teaching content.The use of teaching media is reasonable,and the types and uses of teaching media vary.The behavior of teachers and students in the classroom is reasonable,reflecting the student-oriented teaching philosophy,but the students are lack of innovation in the use of media technology.Teachers are good at grasping the rhythm of the classroom.The number of knowledge points taught in each class are more reasonable,but less knowledge is expanded.
