Classes were carried out for beginner learners of Japanese to check the effect that the differences in slide presentation has on the learners' understanding and thinking processes. They were taught using two kinds of methods; one is by presenting the illustration in the slide gradually, the other is showing it all at once. The results of the questionnaire given to the learners suggested that it might promote the understanding and thinking of the learners in the case of the former in the relatively more difficult grammar section, while the latter promotes understanding and thinking in the relatively easier grammar section.
