This study focused on exploring Chilean pre-service English teachers' perceptions regarding the use of structured cooperative groups to learn about Australian historical events and geographical information in the virtual world of Second Life and face-to-face.Currently, there is a dearth of research in the area of pre-service teachers' perceptions in the use of a cooperative approach to learning in these two types of environments.Additionally, it was important to understand if cooperative learning helps to improve preservice teachers' preparation, regardless of the type of environment in which it is implemented.A case study methodology with two case studies, each incorporating two embedded units of analysis, was used to have an in-depth look at the use of cooperation for teaching and learning in Second Life and face-to-face. The cases of Mr "R" and Mr "J" and their respective teachers in each environment were analyzed. Qualitative information gathered from interviews and focus groups showed that both case study participants perceived the use of a cooperative approach to learning as highly beneficial to not only improve their learning but also develop their social skills. Similarly, both teachers, Miss "A" and Miss "V", also reflected on the benefits of cooperation for improving their teaching practices.Qualitative data claims were backed up by quantitative information obtained from a Cooperative Learning Questionnaire and the achievement test. An ANOVA questionnaire analysis showed that there were no significant differences in cooperation perception in both types of environments. This means that cooperation is perceived similarly regardless of the context in which it is used. Additionally, an ANCOVA analysis was conducted for test results which showed that even though the virtual group performed significantly better the second time, the face-to face group also improved its performance the second time. This means that a cooperative approach to learning had a positive significant impact on both types of environments.Based on the results of this study, the development of a framework to assist establishing cooperative group work in virtual environments is proposed. The framework combines Salmon's (2011) five-stage model, the elements that a structured cooperative group must comprehend (Gillies, 2007), Hannafin, Land andOliver (1983) and Roehler and Cantlon's (1997) scaffolding components. The proposed framework stands as a helpful element towards effectively implementing cooperative learning in virtual environments and making virtual environments even more effective when used in a learning experience.ii In summary, this study helped to explore Chilean pre-service English teachers' perceptions of the use of a cooperative approach to learn about Australia. It also contributed to create a holistic picture of the benefits that working under a cooperative approach entails, regardless of the context. Further, the use of a virtual world such as Second Life proved that cooperative learning can be fostered by the visu...
