In her piece, The Missing Link in School Reform, she writes that many so-called reformers argue for increasing human capital — factors such as teacher experience, subject knowledge, and pedagogical skills — in schools. “The power of teacher human capital, the value of outsiders, and the centrality of the principal in instructional practice—form the implicit or explicit core of many reform efforts today.” These beliefs are not research-based, however.
The positive effects of social capital have been demonstrated by empirical research. What’s social capital? Leana says that social capital
resides in the relationships among teachers. In response to the question ‘Why are some teachers better than others?’ a human capital perspective would answer that some teachers are just better trained, more gifted, or more motivated. A social capital perspective would answer the same question by looking not just at what a teacher knows, but also where she gets that knowledge. If she has a problem with a particular student, where does the teacher go for information and advice? Who does she use to sound out her own ideas or assumptions about teaching? Who does she confide in about the gaps in her understanding of her subject knowledge?
In a study of more than 1,200 kindergarten through fifth grade teachers in New York City Leana and her co-workers found the following.
Students showed higher gains in math achievement when their teachers reported frequent conversations with their peers that centered on math, and when there was a feeling of trust or closeness among teachers. In other words, teacher social capital was a significant predictor of student achievement gains above and beyond teacher experience or ability in the classroom.
Linette Branham, CEA’s director of policy and professional practice, says that CEA has been advocating for years for professional learning for teachers that fits this model.
“When teachers work together with their colleagues to look at student learning data, use it to determine student learning needs, and then determine their own learning needs based on what students need, they design programs that really help improve instruction. That’s social capital at its finest.”
Professional development training that CEA carried out for local associations last year is based on this collaborative approach.
“It’s great to see more research supporting the importance of social capital,” said Branham. “We hope this research draws more attention to the importance of teacher collaboration around student instruction.”
