All active students, 157 in total, in an English Education Study Program in South Sumatra, Indonesia were taken in as the subjects of the study. The data were collected using Attitude toward Internet Use in Language Learning Questionnaire and students’ cumulative GPA.

Furthermore, the results of the Pearson correlation indicated that there was a significant fair positive association between pre-service teachers’ attitude toward internet use in learning and academic achievement, (r(157) = .443, p = .001).
