The Influence Of Prior Knowledge And Illustration Types On College Students' Cognitive Load And Reading Performance

In the learning process,the main source of student information is textbooks.In previous textbooks,the proportion of texts and texts is quite large.In recent years,the proportion of illustrations in texts has increased,especially in the reading of scientific texts.The reading of scientific texts involves complex cognitive processes.It is necessary to integrate illustrations and textual information in order to better understand the content of the articles.In the reading process,cognitive load has a very important impact on the understanding of the text.Different reading materials will lead to different cognitive load.Different cognitive load will affect the understanding of the text.Prior knowledge and illustration materials are two very important factors that affect cognitive load.This paper discusses the influence of different prior knowledge and illustration types on cognitive load and reading performance.In this study,30 psychology majors and 30 non-psychology undergraduates at Northeast Normal University were selected as subjects,and 2(with prior knowledge: yeso)× 3(inset type: no illustrations\modified illustrations\illustrative illustrations)Two-factor experimental design between subjects,examining the impact of internal cognitive load and external cognitive load on text reading in colleges.turn out:(1)Subjects with prior knowledge have significantly higher reading performance than those without prior knowledge,and those with prior knowledge have lower cognitive load;(2)For subjects with prior knowledge,the lowest cognitive reading score was highest for reading illustrative illustrations,and the cognitive load and reading scores for reading modified illustrations and reading non-illustrated examples were not.Significant differences;(3)For subjects who do not have prior knowledge,there are differences in the cognitive load and reading scores at the three levels of the illustration type,among which the cognitive load under the condition of the explanatory illustration group is the lowest reading.The results were the highest.The cognitive load of the modified graph group had the lowest reading scores,and the highest reading score of the cognitive load was the second with no illustration group.
