Good teachers help students to realise their genetic potential at reading

Genetic studies suggest that genes have a big influence on a child’s reading ability. Twins, for example, tend to share similar reading skills regardless of whether they share the same teacher. On the other hand, other studies have found that the quality of teaching that a child receives also has a big impact on their fluency with the written word. How can we make sense of these apparently conflicting results? Which is more important for a child’s ability to read: the genes they inherit from their parents, or the quality of the teaching they receive? According to a new study, the answer, perhaps unsurprisingly, is both. Genes do have a strong effect on a child’s reading ability, but good teaching is vital for helping them to realise that potential. In classes with poor teachers, all the kids suffer regardless of the innate abilities bestowed by their genes. In classes with ...
