Another limitation of this study is the use of problems from only two mathematical
content areas for the measurement of affect, so a potential transfer to problems from
other mathematical content areas is an open issue.
Also, we do not know how sustainable such changes are and how easily they can be adopted in everyday teaching practice.
It likely depends on the frequency with which teachers apply such cooperation scripts and use modelling problems in their lessons.
Observing teaching practices in the classroom for a longer period after the intervention combined with a measurement of affect a few months later would be an important task for future research.
Another interesting question is how effective an “operative-strategic” teaching style can be when applied to other problem types. Further research studies are needed to answer all of these questions.
