What’s The Evidence on School Devices and Software Improving Student Learning?


The historical record is rich in evidence that research findings have played a subordinate role in making educational policy. Often, policy choices were (and are) political decisions. There was no research, for example, that found establishing tax-supported public schools in the early 19th century was better than educating youth through private academies. No studies persuaded late-19th century educators to import the kindergarten into public schools. Ditto for bringing computers into schools a century later.
So it is hardly surprising, then, that many others, including myself, have been skeptical of the popular idea that evidence-based policymaking and evidence-based instruction can drive teaching practice. Those doubts have grown larger when one notes what has occurred in clinical medicine with its frequent U-turns in evidence-based “best practices.”
Consider, for example, how new studies have often reversed prior “evidence-based” medical procedures.
*Hormone therapy for post-menopausal women to reduce heart attacks wasfound to be more harmful than no intervention at all.
*Getting a PSA test to determine whether the prostate gland showed signs of cancer for men over the age of 50 was “best practice” until 2012 when advisory panels of doctors recommended that no one under 55 should be tested and those older  might be tested if they had family histories of prostate cancer.
And then there are new studies that recommend women to have annual mammograms, not at age  50 as recommended for decades, but at age 40. Or research syntheses (sometimes called “meta-analyses”) that showed anti-
