David:

We add our indigenous knowledge to the content to make it more relevant to the students as we have a lot of indigenous practices that were passed down from our ancestors. In addition, the TPACK (technological, pedagogical, and content knowledge) model tends to overlook Context (i.e., it should be TPACCK) as our teachers face constraints in their classrooms (e.g., limited resources) so that we adapt models accordingly. I hope this answers your question.

We use analysis and discussion of classroom situations. In some cases they are real situations , transcribed or video-taped; in other cases we prefabricate that situations intended to highlight the difficulties of student learning, proper selection of examples or the use of certain strategy or teaching resource.
