Microlecture Development And Application Research Of General Technology In High School

At the end of 2019,a sudden Covid-19 brought an unprecedented impact on education.The teaching activities of teachers and students in "homes",how to carry out distance teaching,innovate online teaching mode,and improve the digital level of teachers,have brought great challenges to education.In the past year,vigorously promoting education informatization has become the primary task of the education sector.During this period,information technology has become an important weapon for education and anti-epidemic.It has created an online learning environment,established a variety of network resource libraries,etc.to minimize the impact of the epidemic on teaching activities,and to be able to smoothly not be restricted by time and space.Carry out to maximize the realization of education equity.In such an environment,as a kind of "short,small,precise and fierce " digital learning resources,microlecture can meet the needs of learners to use mobile terminals for learning anytime and anywhere,and become a "good resource " for teachers and students.However,the quality of microlecture determines the teaching effect of microlecture,which is also a focus of many educators.Based on the core literacy of the subject,this research explores the development and application of microlecture in combination with specific subjects.General technology is a compulsory course for ordinary high school students.It is a course based on practice and focusing on creativity.It is also a basic component of quality education.Today,with the rapid development of education informatization,digital teaching resources on general technical courses on the network platform are relatively scarce.The purpose of this research is to design and develop microlecture for learning difficulties in general high school general technical courses,expand the general high school general technical curriculum digital teaching resource library,and apply it to teaching practice to solve problems caused by lack of teaching resources and insufficient hardware.Teaching problems,changing the status quo of unequal educational resources,and maximizing teaching benefits.The main body of the thesis has the following parts:The first part conducts research on the literature and resources of network microlecture,expounds the development status of microlecture at home and abroad,understands the current situation of domestic microlecture research and application based on general technical courses,and sorts out the application and characteristics of microlecture in general technical courses at home and abroad.The second part understands general high school general technical course teaching situation,through reading course standard,analyzes course content characteristic,course goal characteristic.Combining the actual teaching situation and the students’ academic conditions,we can find the learning difficulties in the general technology courses,the analyst students’ microlecture requirements on the learning difficulties of the general technology courses,and make breakthroughs in the learning difficulties of the "three views" and "control system".Strategies to provide ideas for the design and development of micro-courses for general technical learning difficulties.The third part sorts out the principles and standards of microlecture design and development,and designs the microlecture according to the learning difficulties proposed in this research;sorts out the tools and process of microlecture development,and takes the learning difficulties of "three-view reading" as an example Carry out microlecture development.The fourth part takes part of the students in Chongqing Fengdu High School as the practical objects,conducts the practical application research of microlecture,and reflects and summarizes the design and development effects and practical application effects of the microlecture through performance analysis and questionnaire survey.The fifth part is the summary and prospect of this research.Through research,it is found that targeted and high-quality microlecture design is the key to microlecture development,which can effectively improve teaching quality and provide the development of digital teaching resources for general technical courses in general high schools in Chongqing.
