Online learning is one of the newest efforts of mainstream healthcare education. It has been cited as providing both an efficient and effective alternative learning medium. This study explored the acceptance of an online orientation program by new healthcare employees and identified several critical factors affecting online learning outcomes. The study applied triangulation methods including surveys, interviews, and test scores. Data were captured from 154 questionnaires (with a response rate of 78.2%) with related test scores and 13 participant interviews. The results showed that new healthcare employees were positive toward the computer-based learning program. "Perceived ease of use" and "perceived usefulness" were the major variables predicting technology acceptance, whereas "learner satisfaction" and "continued intention to use" were the major indices for the learning outcomes. Test scores, however, did not reveal any statistical impact. Additionally, human-computer interaction, instant feedback, and program content were commented on as factors affecting learning outcomes. Therefore, online learning is suitable for new healthcare employees, both in the orientation stage and as a follow-up learning method. The results of this study can help support the development of educational technology online programs.
