The Impacts Of Agent-Based Multimedia On Retention And Transfer Of The Middle School Students

Nowadays, with the rapid development of worldwide information technology, the multimedia technique is more and more permeating in the teaching field In this article, based on the cognitive psychology thoughts and theory, the author investigated whether guidance and reflection would facilitate science learning in an interactive multimedia game.In the first part, the author raised the limited of the existing research by interpreting the implication of multimedia, multimedia teaching and the theory of multimedia teaching, reviewing the national and international related research.The second part was experimental research. Through the self-made interactive multimedia courseware for 350 students for the pre-test screening, learning, tests and data collected, their achievements and accomplishments results were analyzed to verify the assumptions. The conclusions were:First, In the Agent-based interactive multimedia environment, self-explaining could help the low learning achievement group, but could not improve the retention of the high learning achievement significantly. Therefore, in interactive multimedia learning, it is unnecessary to require the high achievement students to reflect when they want to solve some problems through retention; However, when they want to solve some problems through transfer, in order to improve students'achievements, they can require all students to reflect.Second, in the multimedia teaching, too much information could enhance the cognitive load. Too many words or illustrations and animation information might guide learners overloading, it would impede learning. The learning achievement of different learners should adopt different ways of guidance. In the condition of reflection, the high learning achievement students who only provide written guidance can achieve the desired learning, However, more animation guidance will help the high learning achievement group without reflection, the low learning achievement group need more words guidance than the high.At last, the future views were discussed.
