The mathematics class using the tablet PCs: Why do not Japanese Teachers use them?

In this paper, we will consider about the reason of using Tablet PCs. Japanese teachers do not use Tablet PCs so much. The reason is the research question. Japanese Government is supporting financially for teachers to use the projectors and computers in the classroom. Recently, teachers using Tablet PCs are increasing, but there are teachers who do not use Tablet PCs, too. In the 1^st step, several studies were considered. And we checked its educational possibility and expectation of Tablet PCs. For example, in early childhood showed that teaching with Tablet PCs contributed significantly to the development of children's mathematical ability. In the 2^nd step, we analyzed the mathematics class using Tablet PCs about the percentage of the elementary school 5^th grade in Japan. We analysed carefully about understandings of children and instructions of teacher. In the 3^rd step, as the case study, we considered whether instruction by Tablet PCs was proper in detail and we argued the result based on several studies. In this paper, at the end, we pointed out 2 points. First, children's understanding deepens by Tablet PCs. Next, there is little contribution to bring the flexibility and creativity up.
