I agree with what Gordon wrote about halo effects.

I think, Gordon, that your work puts the horse bback in front of the cart
where it belongs. If the goal of educational research is to improve the
effectiveness of what transpires in schools, why should we accept the
assumption that any improvement that results must be generatlized and
distant from the research site in space and time. Why not begin assessing
the quality of our research in terms of immediate impact which can
actually be traced directly to the work we've done.
I believe a great deal of the research that becomes influential due to our
penchant for assessing research in formal, decontextualized terms, would
be (rightly) revealed as doing more harm than good, an effect that might
be prevented if we applied different criteria.
