Hi Maha, wonder if writing in the guidebook “style” persuades their authors they are experts in the field? Or maybe they feel pressure to be opinionated in order to seem genuine? In 2008 I went from working in the construction trades to doing a data collection project on transitioning college teachers from face to face into online instruction. Being in the midst of change myself drew my attention to the effects of beginning something new for our instructors who were mostly in mid-career and very used to relying on themselves yet stripped of their confidence by all sorts of generalizations about technology.
In the end my research was thrown out for a more top-down program that told the instructors what to do but never allowed them to own the learning in their own selves. Six years later the college is stuck with no progress and frustrated teachers.
Because I was unqualified to to do academic research my results were, I guess, suspect and considered unusable. Alternately, since I only knew research from some minor journalism courses and by asking “dumb” questions, my data was at least fresh from the field.
As a generalization of my own I’d say the interest in new educational models come from wanting to shed some those people that think they know more than they do:-)
