The aim of this research involves the re-arrangement of the definition of the educational multimedia, its well-suited contents and applications, and the quantitive measurement of the efficiency of learning with multimedia. The followings are the achievments of this research.(1) Survey of Advanced Usage of MultiMedia in the United StatesThe successfully-used examples of multimedia education and the techniques to improve educational efficiency are surveyed in the United States, as an advanced nation of multimedia education.(2) Learning Efficiency Measurement using CD-ROM-Based DictionaryThe electronic dictionary (CD-ROM-based dictionary) and the conventional dictionary are compared in terms of the learning efficiency, when learning the English words with them.(3) Presentation and Learning Efficiency of 3-Dimensional DisplayThe relationship between the floating height of character and the readability are investigated, when 3-D display is used for character presentation.(4) Presentation Efficiency by using HDTVThe advantage of HDTV display is investigated in comparison with the conventional NTSC display, in terms of the learners' recognition time when the mental-rotation task is given to learners via each display. As a result, the recognition time with HDTV presented smaller value than with NTSC with meaningful significance, especially when the presented figures are complicated.Finally, all the above results are generalized to obtain the information on the learning efficiency of multimedia education.
