We conducted a randomized experiment targeting 322 Japanese high school students to examine the impacts of a newly developed English-language learning program. The treated students were offered an opportunity to communicate for 25 minutes with English-speaking Filipino teachers via Skype several times a week over a 5-month period as an extracurricular activity. The results show that the Skype program increased the interest of the treated students in an international vocation and in foreign affairs. However, the students did not improve their English communication abilities, as measured by standardized tests, probably because of the program's low utilization rate. Further investigation showed that the utilization rate was particularly low among students demonstrating a tendency to procrastinate. These results suggest the importance of maintaining students’ motivation to keep using such information and communication technology-assisted learning programs if they are not already incorporated into the existing curriculum. Having procrastinators self-regulate may be especially crucial.
