Abstract: This paper studies the impact of interactive environment on learning outcomes, and explores the effectiveness of learning outcomes in non-interactive teaching, interactive teaching and teaching environment with different levels of interaction through the channel effect produced by change of tester’s auditory and visual sensory combination. This paper designs a combined teaching test, analyzes the learning effect of learners by combining the combination of different visual and auditory channels with the teaching methods with different levels of interactivity. The experiment in this paper shows that the channel effect can promote learning in the interactive learning environment, and the learning environment with different levels of interaction can also have different effects on the channel effect. The interactive learning environment with a certain degree would promote learning, while the learning environment with higher interaction degree would have negative effects.

Key words: interactivity, channel effect, cognitive load theory, learning environment, effectiveness
