The Influence Of Redundant Information Presentation On Multimedia Learning

Nowadays with the rapid development of information technology, the application of multimedia in the teaching is more and more widespread and popular,, making its learning outcomes for students to achieve the best assistance. American psychologist Richard. E. Mayer conducted a study on multimedia learning system is proposed multimedia learning cognitive theory. Based on the principle of multi-media redundancy of Mayer, focusing on streamlining the on-screen text in varying degrees, in different forms of expression and the location of the impact of multimedia learning different rendering. Mayer’s " lightning formation "to be used as the experimental material, a middle school student to be tried as an experiment and the paper consists of two experiments in total。The purpose of the experiment is to investigate the subjects of a preference for four different levels of on-screen text to streamline and streamline the extent of four different screen text learning. Single factor levels were between four test experimental design, streamlined conditions for four different levels of on-screen text, were no text, keywords text, Summary Text, and Full Text.The second experiment is designed to examine in particular the extent to streamline the on-screen text, different forms of expression as well as on-screen text showing the location of the screen text for multimedia learning effects, namely, how to further improve learning outcomes screen text, and by the difficulty of subjective tests questionnaire study of learners in the learning process to the perceived cognitive load. A streamlined degree2(Summary Text Full Text) x2forms of expression (Consistent Expression, Similar Expression) x rendering position2(Separate Presentation, Combined Presentation) between experimental design was tested. The dependent variable test scores are kept and migration test scores.By experiment:1) Compared with no text and Keyword Text, Summary Text and Full Text of the learning effect is not ideal, but it is the learner’s preferred screen text presentation.2)For the Summary Text is concerned, a similar screen text is significantly better than the same screen text; For the Full Text is concerned, no significant difference between the two.3)Whether it is the Full Text or the Summary Text, the Combined Presentation effect of learning is presented in significantly better than Separate Presentation.4)Whether it is the Full Text or the Summary Text, change the screen text forms of expression have increased cognitive load of learners. And learners consider Separate Presentation is greater difficulty than the Combined Presentation.
