At the same time, if educational intervention research were
decreasing in quantity but increasing in quality, then the decline
would not necessarily be a bad thing. Unfortunately, our findings
revealed that selected intervention research “quality” indicators
might also be decreasing. For example, in the four educational
psychology journals in 1995, 26% of the interventions lasted more
than 1 day, but by 2004, less than 16% lasted more than 1 day.
Moreover, interventions involving school-age children have not
increased. Most critically from a scientific credibility standpoint,
the incidence of randomized intervention studies in the four educational
psychology journals decreased from 34% to 26% during
that same time period.
