The Influence Of Characterization Of Variable Sample On Cognitive Load And Transfer For Sixth Grade Student

Worked example learning, which catches the eyes of lots of researchers,is a hot topic of transfer learning.Worked example call make students obtain the cognitive skills easily,and reduce the cognitive load of novice.The effectiveness of the worked sample learning had been generally confirmed.However,the learning from worked example has shortage,because students often have problem-solving difficulties when they are encountered with questions,which are slightly different from worked example.This is because worked example Can not provide the skills for students to solve more problems.In this study,we design different forms of sample, the different variations sample combination of the with different external representation of the sample whether it helps students to master problem-solving skills, reduce the cognitive load of students, and to transfer the proceeds to the relevant problem-solving skills problem-solving in the field of.This study consists of two parts:the first experiment with different variations of the surface characteristics of the combination of the external representation of primary school students to learn the number of sample transfer of learning effect and the impact of cognitive load; second part discusses the structure of variation and combination of different external representation sample the number of pupils learning and transfer of learning effect of cognitive load.In this study, the following conclusions:Conclusion 1:Variation of surface features three levels, each group was tested in the past migration obviously better than much of the CG; Variation in the sample's surface features,the event type variation of the sample group were tested for cognitive load variation of the sample group was higher than time properties.events, attributes the cognitive load variation of the sample group was higher than the corresponding variation of the sample object group.Conclusion 2:the external representation in the sample, the sample group in the corresponding object, no characterization of the recent migration of the sample group is better than formula sample text sample groups combined line graph representation, far transfer effect should be considered good style in writing Examples of Combinatorial characterization of sample line chart group. Type of variation in the event sample group, no characterization of the sample group was better than in recent migration formula writing sample group and sample line graph representation group, but the effect on migration in the far, the best text formula sample group; the external representation in the sample, the three experimental groups was consistent analysis of variance.No representation is the highest cognitive load groups,the text representation formula set minimum cognitive load, line graph representation groups the highest cognitive load.Conclusion 3:The structure of variation in the sample, the sample group and the variation rules of the parallel variation of the sample group of rules is far better than recent migration migration effect, rules mosaic variation near the sample group migration is far better than the CG. The structure of variation in the sample,the variation of the three levels of cognitive load in the four categories measured,there was significant difference in title,which rules embedded sample group cognitive load than the sample group of parallel rule cognitive load, parallel to the sample group of rules than the rules of cognitive load variation of the sample's cognitive load.Conclusion 4:Text formula characterized the migration of the sample group scored higher than the migration of non-characterized sample group results,the text representation formula sample group scored higher than the migration of the sample line graph characterization of the migration group results, no characterization of the sample group score higher than the line graph representation migration sample group migration results; line graph characterization of the sample group of cognitive load than text formula sample group cognitive load, no characterization of group sample group characterized by cognitive load than text formula sample group cognitive load。...
