Research On The Application Of Micro Courses In Information Science And Technology Courses In Junior High Schools

The "Curriculum Standards of Information Science and Technology for Compulsory Education" released by the Ministry of Education in 2022 proposes that information science and technology should focus on developing digital resources of various media types.Teachers should select teaching resources according to local conditions,make reasonable use of digital resources,optimize the structure of teaching content,and focus on improving students’ core literacy.In current information science and technology teaching,the content of textbooks has not been updated synchronously,and teachers have insufficient understanding of the new curriculum standards,resulting in poor achievement of students’ academic quality.As a type of digital resources,micro courses are increasingly being applied in curriculum teaching due to their short and concise advantages.The main research topic of this study is how to apply micro courses to optimize teaching content,improve students’ learning effectiveness,and improve their academic quality in junior high school information science and technology curriculum teaching.The main work of this study is as follows:(1)Theoretical research on micro courses.By reviewing literature and materials,relevant concepts such as micro courses were clarified,and constructivist learning theory,cognitive load theory,and audiovisual education theory were elaborated as theoretical foundations,providing theoretical support for the application of micro courses in information science and technology teaching in junior high schools.(2)Develop a survey questionnaire to investigate the information science and technology learning situation of junior high school students and their views on micro courses.Combined with interview data with teachers,analyze the current situation of information science and technology teaching in junior high school and explore the problems existing in current information science and technology teaching.(3)Propose corresponding application strategies for micro courses in information science and technology curriculum teaching in response to the problems existing in junior high school information science and technology teaching.(4)Based on the proposed micro course application strategy,design two teaching cases with different contents to test the effectiveness of micro courses in information science and technology course teaching through comparative analysis of students’ learning effectiveness and academic quality achievement.The following conclusions were drawn through research:(1)Through questionnaire surveys and interviews,it was found that there are problems in junior high school information science and technology teaching,such as the need to update teaching content,enrich interdisciplinary content in teaching,and difficulty in meeting the requirements of the new curriculum standards for academic quality.(2)Based on the problems in junior high school information science and technology teaching,this paper proposes reference strategies for the application of micro courses in junior high school information science and technology teaching from three aspects:teaching content,interdisciplinary themes,and academic quality.These strategies mainly include enriching course resources and optimizing teaching content through micro courses;Reasonably selecting micro courses and implementing interdisciplinary themed teaching;Flexible use of micro courses to meet academic quality requirements,etc.(3)Based on the proposed application strategies,two teaching case designs were completed.After specific implementation,it was found that students’ learning outcomes and academic quality were improved,verifying the integration of micro courses and junior high school information science and technology curriculum teaching and the effectiveness of application strategies.
