Abstract In this dissertation study, I examined the extent to which a relational network of teachers, administrators, two-way immersion (TWI) experts and mentors promote productive communities of practice (CoP). In a conventional instruction, teachers are often isolated in their classrooms, and a private practice culture prevails. In 2012, the Two-Way Immersion Network for Catholic Schools (TWIN-CS) was launched in an effort to support school reform by engaging school leaders and teachers to collectively learn toward implementing TWI models in their schools. Using the framework of communities of practice (Wenger, 1999), I employed a case study design (Yin, 2009) to explore a national network of Catholic elementary school educators. Data sources included qualitative data featuring semi-structured interviews and quantitative source from a relational network survey. Qualitative results revealed that organizational features of TWIN-CS are critical in promoting participants’ learning to implement TWI. In particular, participants discussed the annual TWIN Summer Academy and bi-monthly webinars to be instrumental for their learning. Many participants also shared that an expansion of CoPs beyond TWIN-CS further prompted productive learning. However, the qualitative evidence also showed a lack of clear internal and external network structures and role definition, and sustaining connection beyond the Summer Academy and webinars were perceived as a great challenge. Quantitative results suggest that TWIN-CS has a core-and-periphery network structure with the Boston College design team at the innermost core, with visibly dense ties connecting to and from them. Most teachers, on the other hand, occupy the most peripheral positions in this network. Survey evidence also showed that participants generally perceived a much stronger learning relationship within schools and showed less certainty on cross-network relationships. In terms of learning characteristics, majority of the respondents viewed knowledge sharing, trust, and advice-oriented dimensions “strongly” but perceived a lack of data-driven learning for both within school and cross-network. I conclude this study with a discussion of implications for future research and practice.
