Abstract: Online education is a popular paradigm for promoting continuing education for adult learners. However, only a handful of studies have addressed usability issues in the online education environment. Particularly, few studies have integrated the multifaceted usability evaluation into the lifecycle of developing such an environment. This paper will show the integration of usability evaluation into the development process of an online education center. Multifaceted usability evaluation methods were applied at four different stages of the MU Extension web portal’s development. These methods were heuristic evaluation, focus group interview and survey, think-aloud interviewing, and multiple-user simultaneous testing. The results of usability studies at each stage enhanced the development team’s understanding of users’ difficulties, needs, and wants, which served to guide web developers’ subsequent decisions.
