(STANFORD, Calif.) -- Students lucky enough to have a particularly good English teacher might boost their grade in other courses as well. Susanna Loeb, a professor at Stanford Graduate School of Education, and other researchers examined the records of 700,000 New York City third through eighth grade students over a seven-year period and discovered that youngsters performed better in math when they were also taught by good language arts instructors.
Interestingly, the reverse wasn’t nearly as impressive -- that is, students with exceptional math teachers only showed short-term improvement on grades in English courses.
Ben Master, a Stanford doctoral student in education who also worked on the study, remarked, “Great teachers are ultimately those with both short- and long-term effects on student achievement.”
Therefore, the researchers said that schools need to put more emphasis on a teacher’s long-term value to students rather than judging them solely on short-term test scores.
