Better Teachers and Methods DO Make a Difference…
...at least when it comes to teaching reading. This is from an interesting study out of Florida State University that looked at reading achievement using identical twins who had different teachers. The abstract from the report (here) states:
"Children's reading achievement is influenced by genetics as well as by family and school environments. The importance of teacher quality as a specific school environmental influence on reading achievement is unknown. We studied first- and second-grade students in Florida from schools representing diverse environments. Comparison of monozygotic and dizygotic twins, differentiating genetic similarities of 100% and 50%, provided an estimate of genetic variance in reading achievement. Teacher quality was measured by how much reading gain the non-twin classmates achieved. The magnitude of genetic variance associated with twins' oral reading fluency increased as the quality of their teacher increased. In circumstances where the teachers are all excellent, the variability in student reading achievement may appear to be largely due to genetics. However, poor teaching impedes the ability of children to reach their potential."
A further article on this topic (here) quotes lead researcher Jeanette Taylor: "When instruction is less effective, then children's learning potential is not optimized and genetic differences are left unrealized." The article continues as follows.
"The researchers found that good instruction promoted stronger reading development. Without it, children were less likely to reach the potential conferred by their genes. 'When teacher quality is very low, genetic variance is constricted, whereas, when teacher quality is very high, genetic variance blooms,' they report. While teacher quality appears to be an important contributor, other classroom factors, such as classmates and resources, might also influence reading ability, the researchers noted."
With teacher quality gaining increasing attention in U.S. political circles, the study highlights the potential for education to moderate the genetic effects on early reading. "'Putting high-quality teachers in the classroom will not eliminate variability among students nor guarantee equally high achievement from all children, but ignoring teachers as a salient contributor to the classroom environment represents a missed opportunity to promote children's potential in school and their success in life,' the researchers concluded."
