From the experimental results, it was found that both the DGBL group and the e-learning group revealed significantly higher self-efficacy of learning mathematics than the traditional instruction group. As self-efficacy refers to one’s belief or expectation in successfully completing some tasks or achieving some specific objectives , it is inferred that provision of practice and instant feedback using computer and information technologies (e.g., e-books, wireless networks, and multimedia) is able to encourage students to learn mathematics better. Although the students in the e-learning group did not show significantly higher learning motivation and achievement than the traditional instruction group at the time, their self-efficacy reveals the potential of making progress in learning mathematics in the future.
