Teaching English language learners, referred to as emergent multilingual students here, is a complex endeavor including ESL and bilingual teachers, content teachers, and paraeducators, among others, for example special education teachers and reading specialists, to name a few. As a result, the Illinois State Board of Education's (ISBE) guidance for the development of ESL and bilingual education stresses that "intentional and consistent collaboration between all teachers and school personnel serving English learners is a vital component to all effective English learner programs" (ISBE, 2016b). To achieve this level of concerted collaboration within ESL education, ISBE's guidance suggests that educators utilize technology to remove barriers to collaboration and to increase the potential to crowdsource expertise. A 2016 report titled "The Collaboration Imperative" (ISBE, 2016a), written by ESL and bilingual education experts to advise the Illinois State Superintendent of Education, singles out ineffective collaboration among teachers and other stakeholders as a significant challenge to educating emergent multilingual students. To increase the effectiveness of instruction for emergent multilingual students, the ISBE report recommends the creation of digital communities of practice to increase quality collaboration at the district level. This paper provides an example of tools that can be used to increase not only collaboration but also the effectiveness of the role of paraeducators in educating emergent multilingual students. It begins with a brief review of pertinent literature and the theoretical context of activity theory, which serves as the basis for the authors' work. The authors then share their experience providing professional development in a secondary school. They describe their extensive engagement in the context, which enabled them to deeply reflect on their own experiences providing professional development and prompted the development of digital learning tools for ESL educator collaboration. Finally, the newly developed digital tools are detailed, and example scenarios demonstrate how they could be used.
