This issue contains papers from two different genres of CSCL research. First, we have chosen to present two papers that address important issues related to group formation, cognitive group awareness, and the automatization of approaches for improving students' learning processes and outcomes. These studies show clearly how learning can become more productive with computational support. The two other studies are part of the tradition that describes, categorizes, and analyzes important interactional details supported in or by computational tools. All four studies offer new insights into the genesis of specific design features for productive student learning. In some of the papers, the role of teachers is discussed. The teacher's role is important in CSCL studies as an interactional partner scaffolding students in their efforts to become more productive in their academic work.
Classroom discourse and automatic feedbackThe focus of the paper by Melanie Erkens, Daniel Bodemer, and Ulrich Hoppe is on how to scaffold teachers and students through automatic analysis and feedback. This paper grows out of the school of thought that the CSCL environment can enhance and regulate teaching and learning activities through orchestration and scaffolding (Dillenbourg and Jermann 2007;Fischer et al. 2013;Stegmann et al. 2016;Tchounikine 2016). In this paper, the authors analyze teachers' work, investigating how teachers need to appropriate new computational tools into their classroom routine. Classrooms are of course not fixed environments; the Intern. J. Comput.-Support. Collab. Learn (2016) 11:381-385
