Anabolic steroids or more precisely anabolic androgenic steroids (AAS) are a class of synthetic drugs that are designed to mimic the effects of the hormone testosterone. Testosterone is derived in the body from cholesterol, and like other steroid hormones, testosterone has its main effect on tissues. Testosterone enters a body cell and attaches to a receptor which crosses into the cell nucleus where it activates the synthesis of protein.

The Great Homework debate

It can accidentally conflate the bad effects connected to a behavioral or learning problem with the bad effects of the retention. I asked Andrew how a parent should factor in her research when deciding whether to hold a student back. My study is short not a parents how-to guide on retention, she replied by email, explaining that holding a child back is a very personal decision. The most important thing is to address your childs underlying academic problems, whether youre holding him back or passing him on to the next grade. She explained her study is aimed at education policy officials who are deciding whether to have high-stakes tests that determine who moves on and who is held back. My study is an argument about how a very expensive policy, grade retention, may actually undermine our shared goals of ensuring even child gets a quality education, she replied. I would argue that my study is evidence that we might take funds used for an expensive and likely deleterious policy and use them for earlier, pre-school interventions and supplemental services to help get a student up to speed.

The term steroids normally are associated with reference to a class of drugs that are used to treat a variety of medical conditions. Steroids have several uses for medical purposes, such as maintaining sexual characteristics in males following surgery for removal of testes following testicular cancer, in adolescent males suffering with malfunction of the pituitary gland, and following surgery and cancer for that involves loss of muscle tissue.

How much you buy andrews conclusions depends business on how similar you think her paired children are. If there were a characteristic that prompted a parent to hold back one child that his statistical partner doesnt have, then the analysis isnt clean. Her control group (the promoted partner) isnt otherwise identical to the treatment group (the retained child). Andrews data sets didnt list every behavioral problem and learning disability, so she couldnt control for Attention Deficit Hyperactivity disorder (adhd) and other many other conditions. Its quite possible that some of the held-back children had behavior issues or a mild learning disability and the promoted partner child didnt. Years later, when Andrew found that the held-back child didnt graduate from high school, its possible that factors related to the students behavior or learning issues — being placed in an alternative academic track, for example — impeded his academic career and not the psychological scarring. I dont want to suggest that adhd makes it hard to graduate from high school, but i am trying to explain how Andrews research can fall into the same trap that the early research on retention fell into.

Andrew acknowledges that held-back students often show a short-term boost in their grades and test thesis scores, but she believes this boost disappears after just a few years. A sociologist by training, Andrew hypothesizes that being held back is so psychologically scarring that many students fail to regain their confidence in the long-term. In her paper Andrews argues that being held back is a one of the biggest negative events of a childs life. In surveys, students rank being retained in grade second only to a parents death in seriousness in some cases, Andrews wrote. At first blush, the data seem to defy common sense. (Data have a way of doing that!) Kids, especially boys with fall birthdays, are commonly held back in kindergarten as they get another year to mature. I have a hard time believing that theyre 60 percent less likely to graduate from high school than the kid who stayed with his class and moved on to first grade. Unfortunately, andrew wasnt able to test whether kindergarten retention was less scarring than say, fourth grade retention. But by email she explained that the majority of the students were held back in the earliest grades, confirming that she found even held-back kindergarteners less likely to graduate from high school.

Home environment, gender and race were factored in, too. In other words, Andrew matched the held-back students with students who were equally at risk for being held back, but werent. Related story: India data show test scores rise when students are automatically promoted to the next grade. Then Andrew looked at whether these matched students eventually graduated from high school. And thats where she found that the held-back children were 60 percent less likely to have graduated from high school than their matched partners who stayed on grade level. Andrew went one further to see if she could reproduce the results in a different way. Using the 1979 data survey, which included sibling information, she compared children who were held back with their siblings who werent held back. Again, she found the same result. Even in the same family, held-back kids were 60 percent less likely to graduate high school than their brothers and sisters.

Educational evaluation and Policy Analysis,. So a growing consensus was emerging in the research community that holding a kid back in younger grades isnt harmful and sometimes helpful if accompanied by support services, such as summer school, tutoring and advising. And now resume Andrews paper — contradicting the new consensus — lands. Its a quantitatively rigorous study finding harmful effects for younger children. She looked at more than 37,000 children across the United States from two older multi-year surveys (.

Nlsy 1979 and, nels 1988 ) and found that about 10 percent had been held back at school, most of them during the 1980s. The surveys included details of the family characteristics of the children. That allowed Andrew to create 6,500 matched pairs of students, where the retained and non-retained students had similar backgrounds. Their mothers had attained the same level of education and their families had the same household income. The students had scored the same on a pre-school cognitive test. (In laymans terms, they started school with similar IQs). The matched students also had similar behavioral problems, as reported on the surveys.

Brian Jacob and, lars Lefgren studied students in Chicago, where the decision to hold a student back was based on a test score. . The researchers were able to compare the experience of students who scored just below the threshold for passing with the experience of students who scored just above the threshold. Because of test measurement errors, these students were effectively testing at the same level — academically identical. But half were held back and half were promoted. . In a 2009 paper, jacob and Lefgren found that the harmful effects of retention largely melted away when comparing these two groups of students.


Students held back in older grades still suffered a bit, but there was no decrease in high school graduation for students whod been held back young. (Jacob, Brian., and Lars Lefgren. The Effect of Grade retention on High School Completion. American Economic journal: Applied Economics, 1(3 33-58. four years later in 2013, a rand study looking at New York citys experiment with ending social promotion came to a similar conclusion — retention isnt harmful.  It also found that the kids who repeated fifth grade were better off than kids who just squeaked by and passed the test and moved on to sixth grade.

Or was it his ongoing struggle with attention deficit disorder? If he had been promoted, would his academic career turned out differently? These early studies dont say. Even as the low quality research kept showing that holding kids back was bad, a growing chorus of presentation critics urged schools to end social promotion, the practice of passing failing students onto the next grade. Hechinger Report colleague molly callister wrote here, 15 states and the district of Columbia have adopted policies requiring third-grade reading proficiency before a student can move to fourth grade. . Two big cities, Chicago and New York city, undertook ambitious experiments in ending social promotion. Those urban experiments attracted sophisticated researchers.

These studies didnt compare the held-back kids with the kids who were also failing, but were promoted nonetheless. Related story: Why los Angeles sends failing students on to the next grade. This article also appeared here. In data analysis terms, this early research conflated the bad effects being held diary back with the bad effects of the underlying issue that led a school (or a parent) to hold the child back in the first place. Consider a child who has trouble paying attention, cant read by the end of fourth grade and is held back. Say, this child continues to get bad grades, tests poorly and eventually drops out of high school. Did the stigma of repeating fourth grade cause the child to become demoralized and to perform worse at school?

Career, by notre dame sociologist, megan Andrew, published Sept. 26, 2014, in the journal. Social Forces is an empirically solid analysis that adds more weight to those who say retention — what education wonks call repeating a grade — is ultimately harmful. Andrew mined two large data sets in a way no researcher has done before and concludes that kids who repeat a year between kindergarten and fifth grade are 60 percent less likely to graduate high school than kids with similar backgrounds, and even 60 percent less likely. Before i discuss Andrews paper in more detail, its helpful to understand some history. Most early research overstated how harmful it is to be held back a grade. It tended to point out that the struggling kids who repeat a grade dont fare as well as kids who stay with their class, most of whom are not struggling. But thats shoddy research.
