Research On The Application Of Educational Short Videos In The Dual-line Teaching Of Junior Middle School Information Science And Technology Course

With the national focus on digital literacy of citizens and the widespread promotion of digitization in education,there is an increasing emphasis on Information Science and Technology courses(ICT courses)whose main objective is to develop digital literacy among students.By organically combining online and offline learning,dual-line teaching has changed the traditional teaching mode and improved students’ digital literacy,which is currently a hot topic in education reform.As a new digital learning tool,educational short videos can be integrated into dual-line learning to improve teaching efficiency.Therefore,based on the relevant theories,this paper constructs a dua-line teaching model for ICT courses based on educational short videos,which is based on the research and analysis of the feasibility of implementing educational short videos in ICT courses,and verifies the feasibility and effectiveness of the model to improve students’ ICT core literacy,improve the teaching quality of ICT classes,and improve the teaching effectiveness of ICT classes.First of all,by reviewing and reading in detail domestic and foreign “short video”,“educational short video”,“ICT courses”,“dual-line teaching”,to thoroughly and accurately understand the latest research results and development of educational short videos and dual-line teaching in junior middle school ICT courses,to clearly define the concept,reference the design and implementation of the educational short videos by other researchers,establish a solid theoretical foundation for the application of the educational short videos research to dual-line teaching in the junior middle school ICT courses,and provide research on which to build on the ideas in this paper.Secondly,to understand the current situation,problems and analysis of causes related to the use of short videos in ICT courses in junior middle school classrooms.Before constructing a dual-line teaching model for the use of short videos in ICT courses for junior middle school students,the current situation of the use of short videos in ICT courses for junior middle school students,the analysis of problems and causes will be investigated through questionnaires and interviews,and the data of the survey results will be statistically analyzed in order to prepare for the subsequent construction and practical implementation of the teaching model and to provide a direct basis for problem solving..Once again,a dual-line learning model based on educational short videos is being reconstructed for junior middle school ICT courses.By analyzing the constructability of the model and following the principles of instructional model design,using previous research on educational short videos and dual-line teaching,and linking the instructional objectives of a junior middle school ICT courses to the core curriculum,a dual-line teaching model based on educational short videos is constructed and applied to a junior middle school ICT courses,and a comprehensive explanation of the model is presented in three instructional sessions before.Finally,the feasibility and effectiveness of the model was tested.Two experimental classes and one control class with a comparable level of secondary education in grade 8were selected to conduct a quasi-experimental study and design instructional experiments.Based on the data analysis of the experimental results,it was demonstrated that the dual-line teaching model developed in this paper,which is based on educational short videos for ICT courses in junior middle school,can improve the teaching effectiveness of ICT courses teaching,facilitate the cultivation of students’ core ICT knowledge,and contribute to the improvement of students’ digital literacy..
