To investigate the effects that experiences of programming have on parents' concerns about programming education in primary schools, a survey was carried out before and after a programming seminar for children and their parents. Participation in the programming seminar seemed to boost parents' expectations and decrease their anxieties about introducing programming education to primary schools. Findings also suggest that parents' attitudes and confidence in involvement in supplementary instruction at home improved. Since the survey is ongoing, the number of participants in this study was limited. It is necessary to carry out a statistical analysis with more participants.
