Abstract
This study focused on development of evaluation methods and investigation of effectiveness of an ICT teachers' training seminar to promote other teachers' use of ICT in their own schools. We designed a teacher-training seminar to help ICT teachers encourage other teachers' use of ICT and developed evaluation methods of the training seminar. The evaluation methods were based on Kirkpatrick's model of levels 1 through 3. The evaluation results of the training seminar are as follows. Self-evaluation as the reaction level by the participants of the training seminar shows that they could get a sense of satisfaction, be motivated, and acquire concrete methods to promote ICT. By comparing the promotion activities before and after the training with self-evaluation two month after the training, it was found that the teacher training seminar worked well for the participants to maintain motivation at the high level and they still felt the usefulness of their strategies for promoting ICT use. In conclusion, our evaluation methods were able to show effectiveness of teachers' in-service training seminar.
