The authors investigated the effectiveness and impacts of process prompts on students’ learning and computer self-efficacy within the technology-enabled project-based learning (PBL) context in an undergraduate educational technology course. The participants were thirty-five prospective teachers enrolled in a Web-Based Instruction for English Language Teaching (ELT) course. Students’ interviews and reflections revealed that process prompts were important in facilitating problem-solving efforts. The surveys showed significant gains on students’ computer self-efficacy after the completion of technology-enabled PBL.
