The study investigates the role of teacher experience with student change and their enthusiasm as antecedent factors that predict their continuance intention to integrate technology in the classroom. The Partial Least Squares technique was applied to analyze data from 157 teachers in Bangladesh participating in an international development program. The proposed model showed eight significant hypotheses. The variables of teachers’ effort regulation, efficacy on technology integration, teaching enthusiasm, and impact on students significantly influenced continuance intention to integrate technology in the classroom. These factors should be considered when teacher training in international development programs is designed to secure the longer-term effectiveness of aid for education in developing countries. From the finding, we suggest a sustainable framework in the education sector for the effectiveness of international development aid.
