A number of studies have investigated the impact of expansion methods on results in examination tasks, but the control of academic ability has been an issue. The purpose of this study was to eliminate the influence of academic ability as much as possible and to investigate the influence of the method of expansion on the results. We measured the answer time and the number of correct answers using three types of question formats: original, layout change enlargement and simple expansion, using numerical tasks for 37 sighted people. As a result, the answer time was significantly shorter in the order of original, simple expansion, and layout change enlargement. There was no significant difference in the number of correct answers between the expansion methods. The original has the fewest pages and the smallest paper among the three types of expansions. If the number of pages is small, the number of operations for turning pages is reduced, and if the paper is small, the movement distance of the line of sight can be shortened. If the number of pages is large, such as in the case of layout change enlargement, it is expected that it will take time to find side lines and to confirm the range of side lines. For future research, we would like to collect data not only for sighted people but also for visually impaired people and compare it with this data in order to study a fair testing environment.
