Wang, S., & Vasquez, C. (2012). Web 2.0 and Second Language Learning: What Does the Research Tell Us? CALICO Journal, 29(3), 412–430.
The authors found that much research on Web 2.0 technology and language learning is not clearly grounded in theory and that a number of studies suffer from a set of common methodological limitations. The analysis in the review focuses on 29 empirical studies from 2005-2010. The authors also cite previous reviews of research in earlier periods from 1990-2005. The authors have aimed to include all of the recent relevant literature on using Web 2.0 technologies in L2 learning. The study points to the need for well-constructed empirical research projects. Among others, their suggestions include projects that don’t look only at technologies, but also at students’ progress and specific language learning outcomes. They also suggest the need for research on how proficiency and/or intercultural competence are affected by using Web 2.0 tools.
