The following action research provides an overview of student's perceptions of the incorporation of Web 2.0 technologies into in-tandem language learning activities. American and Brazilian college students were partnered in order to work in-tandem through pre-determined language activities using Web 2.0 technologies to learn a second language, prior to studying abroad. Findings indicated both advantages and pitfalls of incorporating Web 2.0 technologies from a learner-centered perspective. Implications for program change included clear directives and protocols for text-based communications between peers and providing back-up options for students when technologies fail to work or are unavailable.
