Research On The Influence Of Graphic Sequence And Clues On Multimedia Learning Of Different Types Of Knowledge

Today,the research oin multimedia learning resources mainly focuses on the simultaneous presentation of graphics and texts.In practical applications,graphics and texts are sometimes limited by the properties of the rendering tools or the nature of the images themselves,resulting in text and images being presented only one after another.Taking the text sequence as the theme,the paper analyzes the status quo of domestic and foreign research,and finds that the influence of graphic sequence on learning effect is divided into two types:it is easier to understand the text after rendering the image first,and it is easier to understand when the text is presented first.According to the analysis of knowledge types in the past experimental materials,it is preliminary to judge the influence of graphic sequence on the learning effects of different types of knowledge.In addition,the review has found that the integration of graphic and textual information is not presented at the same time.In multimedia learning resources,clues,as a form of instructional designrhave important functions of guiding attentionlorganizing and integrating information.Therefore,the clues are added to the study of the sequence of pictures,thereby improving the multimedia learning effect under the sequence of pictures.This study designed two experiments in three experiments to explore the influence of graphic sequence and knowledge types and clues on multimedia learning.The first study explored the impact of graphic sequence and knowledge types on multiledia learning.The experiment used the graphic as the control group at the same time,using 3 factors(text sequence:first text,first image,and text)*2(knowledge type:declarative knowledge,procedural knowledge)design.The results show that the interaction between graphic sequence and knowledge type is significant.The declarative knowledge has good learning effect and low material difficulty in the text-picture order.The learner pays more attention to the picture and the degree of processing.The procedural knowledge is in the picture-text.In the order of learning,the learning effect is better,the material difficulty is low,the learner pays more attention to the text and the picture,and the processing time is more;but the graphic and group learning effect is still the highest.On the basis of the first study,the second study explores the influence of clues on the multimedia learning effects of different knowledge types under the graphical sequence,including Experiment 1 and Experiment 2.Experiment 1 explores the influence of clues on the multimedia learning effect of declarative knowledge under the text-picture sequelce.The results showed that the ligration scores,total scores,and material difficulty of the clue group were higher,and the total gaze time and total gaze times in the eye movement index were more.The experimental results show that in the text-picture sequence,the clue can promote the processing of the graphic infornation and improve the learning effect of the learner.Experiment 2 explores the influence of clues on the multimedia learning effects of procedural knowledge presented in graph-text order.The results showed that there was no significant difference in the academic scores,cognitive load,and various eye movement indicators and wireless cord groups in the clue group.Explain that in the order of graph-text,clues cannot improve the multimedia learning effect of procedural knowledge.The above experimental conclusions show that the multimedia learning of declarative knowledge is suitable for presenting the text after the text is presented first.The addition of the clue can improve the learning effect;the multimedia learning of the procedural knowledge is suitable for presenting the text after the image is presented first,and the clue has little effect.
