Research on Interface Design Strategies of Online Course Video Based on Cognitive Load

Abstract

With the deepening of digital education and information technology, the gradual rise of distance education and Massive Open Online Courses has further promoted the sharing of teaching resources and the fairness of education, However, due to the lack of design strategy guidance, Many online course video interface design is unreasonable, which increases the cognitive load of learners, affects the learning efficiency of learners, and then leads to a high dropout rate. Based on cognitive load theory, this paper analyzes the current situation of online course video interface design in Open Education in our country by using literature analysis and questionnaire survey; Through case study, the design elements of online course video interface are sorted out, and the design elements related to cognitive load are selected from three aspects: intrinsic cognitive load, extrinsic cognitive load and effective cognitive load; In the end, This paper puts forward the design strategy of online course video interface based on cognitive load, and creates the design template of online course video interface, which can be flexibly applied in the design of online course video interface, and proposes solutions to improve the quality of online course from the perspective of design.
