Research On The Influence Of Working Memory Capacity And Mouse Cue When Learning Software Skills From Instructional Videos

With the development of network multimedia technology,learning materials have become more diverse and have various characteristics.This study uses software operation skills learning videos as learning materials to explore the impact of working memory capacity and mouse cues.In order to explore this issue,two rounds of experiments were conducted in this study.Experiment 1 mainly studied the working memory capacity and two mouse types(normal type and "highlighted" type).According to the results of Experiment 1,three mouse types(no mouse,mouse,mouse and wireframe)were designed,and Experiment 2 was carried out by using eye tracking technology.Experiment 1:in order to verify the influence of working memory and mouse cue on self-learning results when learning software skills from a screen-captured video,two videos with same instructional content while different mouse types were designed,one with standard mouse shape,and the other with a high-lightened mouse shape.114 undergraduates participated in a working memory test called three-back experimental paradigm,and 44 students with test score falling into either the highest group or the lowest group were selected to watch one of the two screen-captured videos randomly,and then to finish retaining test,transferring test,and several cognitive load assessments.The results indicated that: first,self-learning results were significantly influenced by working memory.The higher the working memory,the better the self-learning performance,as well as the lower the intrinsic cognitive load and the extrinsic cognitive load.But the germane cognitive load was not influenced by working memory.Second,self-learning results,such as self-learning performance,germane cognitive load and extrinsic cognitive load were not significantly influenced by the type of mouse cue,except for the intrinsic cognitive load.Experiment 2 is to test the influence of mouse and wireframe cues on the self-learningeffect of software operation skills teaching videos.Three kinds of videos with the same teaching content and different mouse shape are designed: no mouse,normal mouse,mouse plus wire frame.According to the previous knowledge test,33 subjects were selected to enter the formal experiment.Participants were randomly assigned to the experimental group to learn the video of the corresponding group and record the eye movement data of the subjects.When the study is completed,the participants complete the retaining and migration test.The study found that the cue effect was significant in the learning effect,the score of the wireframe cue group was the highest,and the difference of the mouse cues was not significant.From the eye movement data,there were significant differences in the average gaze time of the three mouse cues.Through the above two experiments,it can be concluded that the working memory capacity can affect the learner's learning effect and cognitive load;in the operation skill learning,the simple change of the mouse can not reach the extent of affecting the learning effect,but it can affect the cognitive load and attention to some extent;the mouse to add wireframe cues can improve the learner's learning effect,and at the same time play a good attention guide;learners with different learning effects have differences in information processing.
