"Creation of storytelling" using PowerPoint was conducted so as to raise computer literacy and to foster the students' self-understanding. They were required to draw a figure using Excel and stick it on a report. They were expected to write their reports using Word. The pre and post literacy in functions of the software of three kinds was investigated to know the computer literacy which was able to be developed by "creating the storytelling". As a result, the pre literacy in functions of PowerPoint was lower than those of Word and Excel. After this practice, the post literacy in the functions of PowerPoint significantly became higher. This paper will report that students became able to utilize the functions of PowerPoint as same as those of Word and Excel. Principal component analysis will be conducted for elongation in the literacy of PowerPoint. Cluster analysis will be conducted using the principal component score as a variable. As the results, students will be divided into four groups: the group whose elongation in the general literacy of PowerPoint is higher, the group whose elongation in literacy related to an animation is higher, the group whose elongation in the overall literacy of PowerPoint is third, and the group whose elongation in the skill of PowerPoint and Excel is lowest.
