This article is to report an action research conducted in two sections of a course called Second Language Acquisition and Development during the fall semester of 2011 and the spring semester of 2012. By focusing on a three-way blended learning (BL) environment--face-to-face (F2F), eLearning, and Second Life (SL, a virtual-world environment), this study attempts to explore students' experiences, perceptions, and reflections on multimedia technology and apply the findings to help improve a second language acquisition course. By conducting 36 interviews totally from two semesters (15 from the first semester and 21 from the second semester) as well as 30 course observations (20 F2F and 10 SL observations), the result of the study suggests students preferred the combination of F2F and eLearning. The study concludes that SL application needs to be reevaluated for a better BL instructional structure in terms of student's skills, training, high-standard hardware equipment, and design of virtual installation in order to effectively integrate it into the course of Second Language Acquisition and Development.
