SMI-based Media Portfolio Research

In this paper,the BaiCiZhan is taken as the research object,and eye movement and EEG stimulation experiments are designed respectively.Based on the behavioral analysis,eye movement analysis and ERP(event related potential)analysis of learning process,we found the differences of learning effect and learning process between high score group and low score group in three media combinations.Results confirm the rationality of double encoding theory from three aspects.The eye movement experiment data analysis results show that from the learning effect,the high score group in the three ways the correct rate is higher than the low score group and the reaction time is shorter than the low score;the correct rate of image memory are higher than the rate of correct word memory mode.From the learning effect,high and low groups there are two emphases in three ways:word meaning and area,especially in words way,the subjects pay little attention to the region,especially in the image memory mode;on the whole,high score group is more stable than the low score group.In the way of image memory,high score group can pay more attention to the word area and the meaning area,while the low group is easy to be attracted by the image part.The ERP component of old words recognition process is analyzed,and results show that the old/new effect of graphical presentation is more obvious than the word presentation,results provide the theoretical support to improve the effect of educational assistance software.
