The Production And Application Of Micro Courses Over Information Technology Curriculum In Junior High School Under The Background Of Blended Learning

The Ministry of Education's "Education Informatization(2.0)Action Plan"(2018)clearly pointed out that it is necessary to vigorously develop high-quality educational resources,realize the in-depth integration of informatization and education,and realize the deepening reform of education through informationization,thereby promoting the development of educational modernization pace.With the advent of the era of artificial intelligence,the content of information technology courses is constantly changing.How to make junior high school students learn new content of information technology and improve students' learning effects in a limited time,and better realize the teaching objectives of information technology subjects.It has attracted the attention of more and more scholars.In recent years,some scholars in the field of education and technology have proposed the theory of mixed learning.The so-called mixed learning is to combine face-to-face learning with online learning to open up the classroom and extracurricular links to promote the improvement of learning effects.As one of the compulsory courses in junior high school,the information technology course is a course that is constantly updated and changed with the development of the times.The information technology course is highly operational,the teaching content is mostly practical,and the content of Microlecture is short and refined.Strong personality,combined with the mixed learning mode,can solve the problem of repeated demonstrations of teachers in traditional information technology classroom teaching and difficult to take into account the learning of students at different levels.Therefore,the research and application of the Microlecture in the junior high school information technology course has certain practical significance on how to improve the quality of basic education,especially the effect of information technology classroom,and the research results can be extended to other countries.The discipline,thus achieving an overall improvement in the quality of basic education.This research takes the information technology classroom of the Fourth Middle School of Nanning as the research object,and uses the methods of literature data,experimental contrast,investigation and analysis,etc.,under the guidance of modern information technology theory such as mixed learning theory and constructivist theory,through the production of “ The Microlecture and the way to collect other high-quality “micro-curriculum” resources,carry out applied research in the classroom,so as to analyze the application effect and extract a new mode of classroom extracurricular teaching that can be promoted.The content of the research is divided into five parts.The first part analyzes the research background and the status quo of research at home and abroad,and summarizes the necessity of the design and production of junior high school information technology Microlecture under the background of mixed learning;the second part is the background of mixed learning.The theoretical basis of the Microlecture research is analyzed.The third part analyzes the subject characteristics and design requirements of the junior high school information technology course,and summarizes the feasibility,design principles and design elements of the Microlecture in the junior high school information technology classroom.And the Microlecture design process is summarized;the fourth part is based on the preliminary analysis of the "micro-class" case design,production and processing;the fifth part through the practical application of the Microlecture,the junior high school information technology classroom Use the Microlecture to assist the teaching and the areas that need improvement,and summarize the deficiencies.
