	abstract = {This study explores teacher educators{\textquoteright} (TEs{\textquoteright}) activity as they support mathematics and science teacher collaboration in co-designing and jointly implementing tasks. We view TEs{\textquoteright} activity through the lens of Activity Theory and expansive learning and draw evidence from data generated within the mascil project that linked mathematics and science teaching with workplace situations through inquiry-based teaching. We focus on five TEs{\textquoteright} actions and goals, use data from their professional development sessions with teachers and from the TEs{\textquoteright} interactions during their own meetings, and highlight the illuminating case of one teacher educator. We trace evidence indicating paths of actions followed by each Teacher Educator and look for indications of their professional learning. Our analysis reveals generic and content-focused actions. All TEs faced different kinds of contradictions and had difficulties handling them. In terms of professional learning, all TEs adapted their prior teacher education practices and appreciated the critical role of epistemological differences between the two disciplines.},
