Analysis And Rethinking On The Teaching Characteristics Of The Optimal Lessons Competition In The High School Information Technology Course

With the promulgation of the new curriculum standards for high school information technology,high school information technology curriculum teaching has entered a new era.In September 2019,the China Educational Technology Association hosted the "Sixth National High School Information Technology Quality Class Exhibition and Exchange Activity",which is also a national class competition based on the concept of the new curriculum standard.This research mainly observes and analyzes the 47 high-quality lesson examples selected in the sixth national high school information technology quality lesson exhibition and exchange activities.The 47 high-quality lesson examples are analyzed by using the observation method and content analysis method combined with the NVivo11 qualitative analysis tool.In-depth analysis of the teaching design plan,lecture video,teaching courseware and teaching video of the "Quality Class Contest",and summarized the teaching characteristics of the "Quality Class Contest" case.The main contents of this research are as follows:First,research and design.Including the construction of the analysis framework of teaching characteristics of high school information technology high-quality course competition cases and the design of various dimensional observation tables.Second,the lesson analysis.Use NVivo11 software to import,create nodes,observe coding,and visualize data analysis of 47 high-quality lesson teaching design plans,lecture videos,teaching courseware and teaching videos.Third,summarize and think.Based on the analysis of the lesson examples,the author summarizes the teaching characteristics of the high school information technology quality course competition cases from the three aspects of teaching content,teaching behavior,teaching resource tools and environment.The specific performance is as follows:Characteristics of teaching content: teaching content can reflect the characteristics of the times;teaching content can be closely linked to the core literacy of the subject;teaching content can be closely linked to the actual situation of students.Characteristics of teaching behavior: teachers can attach importance to the cultivation of students’ autonomous learning ability,and are good at guiding students to think and solve problems actively;teachers can use teaching media and resource tools to optimize classroom teaching and promote students’ knowledge construction;students can use information technology tools to integrate learning resources.Carry out project learning and exchange learning results.Characteristics of teaching resource tools and environmental application:teachers can proficiently use the informationized teaching environment to demonstrate teaching and conduct teaching interaction;the use of teaching resource tools gradually changes from rich to novel;the use of teaching resource tools is diverse and can be effectively integrated into all aspects of classroom teaching.At the same time,the author puts forward relevant teaching suggestions for the above characteristics: In terms of teaching content,it is recommended that teachers focus on the core literacy of information technology,compare,select,and process the content of various versions of teaching materials,and set reasonable teaching goals based on the selected teaching content.In terms of teaching behavior,it is recommended that teachers create learning situations that are in line with the actual life of students,carry out project learning,guide students to discover and ask questions,encourage students to use information technology to solve problems independently,and form diverse learning outcomes;pay attention to teachers’ own teaching wisdom development of.In terms of teaching resource tools and environmental applications,it is recommended that teachers increase their sensitivity to new technologies and new media,and guide students to be resource builders.
