Second Life (SL) is a three dimension virtual world imagined and created by its users. To explore various facets of language learning within SL, faculty members of an American university and a Chinese university took an evaluation research approach to search for appropriate ways to integrate SL into an EFL (English as a Foreign Language) program. This paper reports a part of the research efforts with a focus on the Chinese students' perspectives of an EFL Program in SL. Specifically included in this paper are (a) the Chinese students' perceived technology readiness to use SL for EFL learning, (b) their perceptions of SL, and (c) the EFL Program implemented in SL. The paper reviews related literature and theoretical support, describes the study's context and its implementation procedures, and discusses the evaluation results and implications. Finally, the paper shares with the audience some considerations for integrating SL into an EFL program.

As PBL has gained popularity across disciplines, its move from small medical-school inquiry groups into large-class undergraduate inquiry has led to an increasing need to understand the elements of successful PBL implementations in large classrooms. In this study, we investigated how PBL was appropriated among students to develop historical thinking skills in a 96-person introductory undergraduate history survey course. The video analysis demonstrated that it was initially challenging for students to appropriate the routines and norms of PBL, but instructor interaction with both the students and representational tools in a large classroom provided multiple co-occurring and dynamic supports. This synergistic scaffolding structured around representational tools was instrumental in a semester-long intervention in which we supported student learning of historical thinking skills by encouraging appropriation of the activities that govern PBL.
