The Effect of Different Feedback Strategy on Learning Outcome inMicro-video Course Learning

ABSTRACT

The outbreak of COVID-19 promotes the development of online learning. Micro-video course has become the mainstream learning resource of online learning because of its concise theme, strong pertinence and vivid content. However, there are few researches on feedback strategy of micro-video course in basic education. Based on the principles of multi-media design and ADDIE instructional design model, a micro-video course of robot knowledge was designed in this study. Different feedback strategies(i.e., descriptive feedback (DF), evaluative feedback (EF), suggestive feedback(SF), guiding feedback (GF)) were embedded in the micro-video course. The effects of four feedback strategies on students' learning outcome, cognitive load, and learning motivation were explored through experiment. The results provide some suggestions for the production of basic education micro-video course. © 2022 IEEE.
