Abstract
For the purpose of improvement of an instruction for spreadsheet skills acquisition, I developed the multimedia teaching materials and used them in class. I requested the students who enrolled in the class to take the third and the second grade of the spreadsheet certificate examination by JAPAN TESTING ASSOCIATION to motivate them. The materials are the movie files which include the captured movies showing correct answers of the training tests for the examination on a PC screen with narration, photos and text boxes. In the class the students self-learned the materials and asked their questions to the instructor individually. As a result, the ratio of the successful applicants for the certification examination increased from the conventional data around 80% to 96.1% with the third grade and from the conventional data around 40% to 77.1% with the second grade. In the class the numbers of student's questions asked were decreased so much and the time of the exercise period was remarkably shortened. Furthermore, all the students replied that the teaching materials were very effective or effective to the questionnaire that I carried out after finishing this course.
