“…For pre-implementation setup, we have considered the work of Guth & Rubin (2015), who suggest that collaborating teachers, in a first moment, should share details of the academic culture in their institutions (such as the number of hours per week, grading scheme, expectations in relation to class attendance, participation in class, in-class and out-of-class amount of work) and advise teachers to align objectives and avoid overloading students in order to give them enough time to engage in communication with their peers.
