Abstract
In this study, we interviewed five elementary school teachers about the use of Information Communications Technology (ICT) by teachers and students in the classroom. The school under study had a 1-to-1 tablet PC in each classroom. Interviews were analyzed using the Technological Pedagogical Content Knowledge (TPACK) framework. The results found that, of the 615 pieces of data, it was found that 394 Technological Pedagogical Knowledge (TPK) was most frequently discussed in the results. Technological Knowledge, TPK, and Technological Content Knowledge were further classified as either “conventional teaching tools” or “1-to-1” depending on the object of knowledge, and we created categories in each type of knowledge. The following two points were revealed through the results. 1) Past experience about teachers’ knowledge and skills are important to consider when planning to use tablet PCs. 2) The influence in the shift about ICT use from teachers to students was observed in TK and TCK.
