Research On The Design Of Micro-video Teaching Resources Of Information Technology Course In Secondary School Based On Multimedia Learning Theory

In recent years,micro-video teaching resources have been favored by teachers and students in the front-line for their refined content,diverse forms,and repeatable viewing characteristics,and have been widely used in secondary school information technology classroom teaching.Due to the complex structure of information technology courses in secondary schools,many operational learning contents,and loose correlation between course knowledge points,it is difficult for learners to grasp the knowledge content of the course during the classroom time,and learners need to retrospect and review knowledge after class.In order to help students break through the dilemma of information technology learning,this study introduces micro-video teaching resources into information technology teaching in secondary school.From the perspective of Mayer’s multimedia cognitive learning theory,focusing on the key points,difficulties and doubts in the process of information technology teaching,combined with the characteristics of micro-video teaching resources,this study research how to optimize the selection and organization of various media elements in the design of micro-video teaching content,In order to give full play to the best effect of micro-video content structure elements,and achieve the purpose of improving the teaching effect of information technology course.This research adopts literature research method,survey research method,experimental research method and other methods.Firstly,starting from the current situation of the application of micro-video teaching resources,it investigates the current situation of students’ self-learning in secondary school information technology courses,and analyzes the preference and relationship between secondary school students’ use of micro-videos.Then,according to the characteristics of secondary school information technology learners,guided by Meyer’s multimedia cognitive learning theory,this paper puts forward the micro-video design mode and operation process of secondary school information technology course from the aspects of micro-video teaching analysis,microvideo information element presentation,micro-video content design and so on.Finally,the specific operation process and mode are applied to the teaching practice of information technology classroom in secondary school,which further verifies the effectiveness and practicability of the teaching application of micro video design mode and operation process based on multimedia learning theory.The main conclusions of this study are as follows:Firstly,this research explains the basic theory of multimedia learning based on the presentation of teaching content information of micro video resources.Firstly,this study explains the basic theories of multimedia learning,such as the channel system of human expression and processing of knowledge,the learning principle of multimedia learning,and the transformation between related images in the process of multimedia learning.Secondly,this research investigates and analyzes the application status of micro video resources in information technology courses in secondary school and the learning needs of micro-video teaching resources.With the help of questionnaire survey,this study analyzes the current situation of the design and development of micro-video teaching resources in secondary school information technology course from the two aspects of secondary school students’ autonomous learning of information technology course and the use of microvideo,combined with the interview with secondary school information technology teachers,and defines the role and significance of multimedia learning theory to improve the teaching effect of secondary school information technology course.Thirdly,this research explores and constructs the design model and operable process of micro video teaching resources of information technology course in secondary school based on multimedia learning theory.Based on the analysis of secondary school students’ cognitive psychological characteristics and secondary school information technology content,combined with multimedia learning theory,film and television directing theory,this study puts forward the basic design process of micro-video based on micro-video teaching analysis,media presentation form selection and micro-video content design,and then explains each step in detail,it also discusses how to use multimedia learning theory to design micro-video teaching resources.Fourth,this research carried out the case design and experimental demonstration of micro video teaching resources,which provided a practical basis for the research on the design and application effect of micro-video teaching resources in the teaching of information technology course in secondary school.The teaching experiment in this research adopts the quasi-experimental research method.Firstly,the appropriate classes are selected as the experimental group and the control group,and then different microvideo teaching resources are used to conduct teaching experiments in the classroom teaching of the experimental group and the control group.Finally,with the help of student work evaluation form,student evaluation questionnaire and peer evaluation,the data of the experimental group and the control group are compared and analyzed.The data analysis results show that the micro-video teaching resources based on multimedia learning theory can effectively improve the learning effect and cultivate students’ self-learning ability.
