So over the years, there have been periodic big fads in using OT for self-regulation, among other things. Like many other anecdotally-based treatments, it helps some children, not necessarily for the reasons promoted by its practitioners, but has negligible research foundation. BTW, not all practitioners who push unfounded interventions are shady; many are just poor consumers of research. The program I've referenced below has had some media attention in education circles; some variant of this is probably what your teachers are clamoring for. You'll notice that there has been exactly one peer-reviewed article (exploratory study with 7 experimental and 5 control students) regarding its actual effectiveness--and this is based on the list of research posted at the publisher's own website.
Summary of the sole peer-reviewed article:
