In this paper, we present a short description of CoNeTo, a web-based collaborative application that facilitates the communication and negotiation of students' learning activities and inferences about their knowledge states, skill levels, and aptitudes as part of the next-tell EU project (www.next-tell-eu) that is developing methods and tools for technology enhanced formative assessment and pedagogical decision-making. System description, use cases, and an annotated screenshot of CoNeTo are presented. The paper concludes with an outline of future work on the research and development of CoNeTo.
