Abstract
Recently, the use of ICT is recommended for public school education. Teachers are thus required
to develop their teaching skills in response to this trend. The purpose of this study is to clarify the
use of ICT model in simultaneous learning which is based on theory of planned behavior diagram by
Ajzen. This theory enables us to show the factor affecting teachers’ behavior. I investigated 183 home
economics teachers who use ICT by conducting a questionnaire study and analyzing the data by
covariance structural models. The results showed that intentions to use ICT was most strongly affected
by the attitude toward using ICT. Furthermore, it showed that the attitude toward using ICT and
subjective norm on using ICT were positively related with each other. However, the perceived use of ICT
did not influence the other factors. It is useful for the teachers to increase their willingness to use ICT
in simultaneous learning. In addition, the subjective norm on using ICT can be effective in increasing
attitude toward using ICT. It is important for teachers to have the sense of mission and responsibility in
using ICT.
