Education Myths: Part I
Things have been kind of quiet around here lately, and so we thought that over the next few days we'd treat you to a few excerpts from Jay P. Greene's Education Myths: What special-interest groups want YOU to BELIEVE about our SCHOOLS - AND WHY IT ISN'T SO. (This book is available for borrowing from our lending library.)
Today's myth is dubbed "The Myth of Helplessness" - the transformation of difficulties caused by social problems into excuses for inaction. Dr. Greene points out that the plausibility of this myth can easily be tested by looking to see if there are any schools or school districts that have managed to overcome their students' desperate social problems. If even one school has succeeded with low-income students, then this is proof that schools are not helpless in the face of their students' disadvantages. It turns out that, while no school is able to completely overcome its students' problems, some schools are coming tantalizingly close. Schools are definitely not helpless.
The following excerpt discusses the author's research into variations in the effectiveness of the different US states (pp. 44-45).
"Jay Greene and Greg Forster of the Manhattan Institute performed a simple analysis to test the evidence on this question. First, they developed a systematic method for measuring levels of advantages and disadvantages in the student population. They combined measurements of sixteen social factors that researchers agree affect student outcomes, such as poverty, family structure, health, and students who don't speak English well. They call their combined measurement the Teachability Index, since it measures the overall 'teachability' of the student population. Then they tested its validity by examining its statistical relationship with student outcomes; they found that the Teachability Index is a reliable predictor of student outcomes, indicating that it does in fact measure students' teachability.
"Armed with this tool, they compared each state's student characteristics to its level of academic achievement. Specifically, they used each state's Teachability Index score to predict the level of achievement its students would be expected to reach given their level of disadvantages, and then compared each state's actual achievement to its predicted achievement. They found a large degree of variation in how well the school systems in the vairous states overcome student disadvantages....
"Greene and Forster's finding suggest that student achievement depends on more than just the levels of advantages and disadvantages that students face. This would naturally prompt us to ask what factors other than student advantages might produce higher educational outcomes. If we examine the evidence, we find that a number of school strategies have been shown to raise student achievement, even among particularly disadvantaged student populations."
