Under the auspices of the Best Evidence Encyclopedia, Bob Slavin and colleagues Cynthia Lake, Susan Davis, and Nancy Madden released an analysis of the research literature on methods for teaching students who are struggling to learn to read, “Effective Programs for Struggling Readers: A Best-Evidence Synthesis.” In the synthesis they report the results of their examination of nearly 100 studies that used randomized or well-matched control groups, lasted for at least 12 weeks, and employed trustworthy measures of outcomes. The results of their review, which include both effect sizes and narrative descriptions of the studies, provide valuable insight into effective methods for remediating reading problems.
Key Findings
Overall, 96 experimental-control comparisons met the inclusion criteria, of which 38 used random assignment to treatments. Effect sizes (experimental-control differences as a proportion of a standard deviation) were averaged across studies, weighting by sample size.

Multiple intelligences ain’t
Howard Gardner’s Frames of Mind: The Theory of Multiple Intelligences seems to occupy a special place in the pantheon of education memes. I was reminded of this when I read “Not Every Child Is Secretly a Genius” by Christopher Ferguson. Mr. Ferguson’s essay—it appears in the Chronicle of Higher Education, the news source of record for higher educators—politely explains that sustaining Multiple Intelligences (MI) theory is not a good idea.
Rational analyses of the MI evidence by Dan Willingham and Lynn Waterhouse have shown that there are problems with both the theory itself (e.g., most of the eight intelligences are highly correlated, meaning that they are likely measuring the same “thing” for the most part) and its application in education (e.g., methods based on MI do not lead to better outcomes).
Mr. Ferguson’s essay continues in that same tradition. He makes a strong case for his conclusion that “Gardner’s theory of multiple intelligences was a great idea and worth investigating. It’s just not panning out.”
