It is widely believed that “excellent teachers improve student performance”, and past (PDF file) surveys show that teacher qualifications and classroom abilities can affect student performance by up to 30%. Had been. However, a study conducted by a research team at the University of New England that surveyed a total of 4533 twins concluded that the effect of teacher quality and class size on student performance was only about 2-3%.

“We wanted to know how the classroom environment affects students' performance,” said research team

Carly Little . Twins share all or half of their genes, plus many other factors, such as parents, where they live, and the school they attend, making it a good place to investigate the impact of the classroom environment on performance It can be said.

Past studies have shown that the influence of genes in the development of twin literacy is about 40-75%. The remaining tens of percent will depend on factors shared by the twins, such as their parents' educational values and socio-economic conditions, or factors that the twins do not share, such as the learning class.

Based on data of a total of 4533 twins living in the United States and Australia, the research team reads and writes twins from kindergarten to second grader (second grader of Japanese elementary school), third grader (third grader of Japanese elementary school), fifth grader We investigated the influence of the classroom environment on the reading, writing, and computing ability of twins at the stages of (5th graders in Japanese elementary school), 7th graders (1st graders in middle school in Japan), and 9th graders (3rd graders in middle school in Japan)

As a result of the analysis, it was found that even if the twins were studying in different classrooms or studying in the same classroom, there was little effect on the difference in grades. According to the research team, the effect of classroom differences on the difference in twin performance was about 2-3%. On the other hand, 60% of the differences in performance between the twin pairs were due to genetic influences, and the rest were due to other environmental factors including differences in the school itself.

Although this study did not show that teacher quality has a major impact on student performance, the theory that teacher quality has a great influence on students is widely accepted. In the United States, teachers are responsible for student performance based on the premise that teacher quality affects student performance. In addition, many people should recall a particular teacher as saying that “I was greatly influenced by the teacher at that time and changed my life,” Little said, “It ’s just a personal experience between the teacher and you. '

“Our data cannot detect the personal experience, but only the effects of the average classroom.” “Our research is a central area of literacy and computational skills, and teachers are fair to students. 'It suggests that we are educating,' Little said.
