Influence of Instructors' Body Language on Students' Learning Outcome in Micro Lectures

Abstract

Teacher's body language has been widely used in micro lecture. Researchers began to pay attention to the influence of teacher's body language on students' learning effect and cognitive load, but there was no unified research conclusion. For this reason, three groups of video (group A including sign language, head movements and expressions, group including head movements and expressions only, and group C no body language group) were set up for the micro lecture of declarative knowledge type to investigate the influence of teachers' body language on learning effect and cognitive load. The experimental results showed that the teacher's body language has a significant influence on the students' learning effect in the micro lecture of declarative knowledge, but has no significant influence on the cognitive load. Attention should be paid to the application of body language in the production of micro lecture of declarative knowledge type.
