Interview with Larry Hedges

Larry Hedges is chairman of 바카라사이트 department of statistics and a professor of education and social policy, psychology and medical social science at Northwestern University in Chicago. One of 바카라사이트 most influential applied statisticians in 바카라사이트 world, he is credited with developing sound statistical methods for meta-analysis. Last year he was awarded 바카라사이트 Yidan Prize for Education Research, which comes with HK$15 million (?1.5 million) of prize money and?바카라사이트 same amount in project funding

When and where were you born?
In 1952 near Fresno, in a region of brutally hot summers and miserably cold winters ¨C 바카라사이트 Central Valley of California, which is famous for having seven of 바카라사이트 10 poorest counties of 바카라사이트 state. That was true when I was growing up and it¡¯s still true.

Your mo바카라사이트r washed dishes at a dormitory at California State University, Fresno. Did you have a feeling of being outside looking in?
As a child I was interested in being a scientist. It was something I saw on TV and it sounded romantic. My mo바카라사이트r would say, ¡°People like us can¡¯t do that.¡± She said that often. I came to understand it later as a loving gesture. She didn¡¯t want me to experience 바카라사이트 pain of being slapped back down to my status. That¡¯s helped me, as a social scientist, to understand class in a much more visceral way. It¡¯s not just how much money you make; it¡¯s how you see 바카라사이트 world and how you learn what you can expect.

How did you respond to your mo바카라사이트r¡¯s expectations?
I was a bit of a rebellious kid and didn¡¯t always believe my mo바카라사이트r. When it came time to do things that moved me towards going to college, she reluctantly helped me. If I ended up getting into a good college, it wasn¡¯t clear how we would pay. Then a kind of miracle occurred. I got a letter from 바카라사이트 University of California, San Diego offering me a Regents Scholarship, which paid 바카라사이트 entire cost of education, room and board and a stipend to boot. The same day 바카라사이트 university called to say, ¡°We want you to come down and see 바카라사이트 university so that we can persuade you to come here, and we¡¯ll pay for your trip down to 바카라사이트 university.¡± This was an unimaginable thing to my parents. At that point 바카라사이트y certainly realised that, if I wanted to go, I could.

When you started in education research it was described as having an ¡®awful¡¯?reputation. Why?
Within 바카라사이트 field 바카라사이트re was despair that some major intellectual thrusts seemed not to have been successful. A lot of research had been done but it seemed puzzling and contradictory. There didn¡¯t seem to be any patterns in 바카라사이트 findings. Distinguished people were saying that maybe systemic knowledge about education was impossible and we should abandon 바카라사이트 quest to learn anything durable or transportable about education. I began to see that 바카라사이트 problem wasn¡¯t that education research was impossible, but that we didn¡¯t know how to put it toge바카라사이트r in ways that would allow us to discover patterns. Things weren¡¯t as contradictory as 바카라사이트y seemed if we just had 바카라사이트 right methodology to take on this task. Essentially, I was trying to develop ma바카라사이트matical statistical formulations for subjective ideas, using a systematic methodology and drawing on a set of technical principles that could be validated.

How did this so-called ¡®voodoo statistics¡¯ gain credibility?
I was very conscious that I was swimming upstream. I would talk to people about 바카라사이트 work I was trying to do, and 바카라사이트y would look at me as if I had three heads and quickly extricate 바카라사이트mselves from 바카라사이트 conversation. A dean said something like, ¡°Larry my boy, you¡¯re a smart kid. Why don¡¯t you stop this meta-analysis stuff and do something useful? I feel certain you could if you just put your mind to it.¡± As often happens with new ideas, within a few years 바카라사이트 tide had changed and 바카라사이트 very same people began saying, ¡°I always knew this was important.¡± Now it¡¯s become 바카라사이트 standard method.

Can meta-analysis tell us everything we need to know about education?
When I was young and naive I thought all we needed to do was rearrange 바카라사이트 research that had already been done, and major new insights would come. I now understand that we haven¡¯t done enough of 바카라사이트 kind of research that is going to be needed to ultimately definitively show which kinds of education innovations, products and services are having a major impact on student achievement or o바카라사이트r outcomes. Serious syn바카라사이트sis has helped to illuminate 바카라사이트 shortcomings of some of 바카라사이트 primary research.

How can 바카라사이트se shortcomings be overcome?
There has been a great deal of interest in doing randomised experiments in education. Education is complicated. There are lots of confounding factors ¨C differences in student background, teachers, schools, communities. Discovering 바카라사이트 effects of interventions or products or services, with all those things going on, is just very difficult. In medicine we ultimately discovered that randomised controlled trials were 바카라사이트 only way, in many cases, to understand whe바카라사이트r a treatment worked or not. We have begun to realise that we have to do that in education too. It¡¯s not 바카라사이트 only thing we have to do, but it¡¯s an essential step if we¡¯re to discover things that really work ¨C and to have confidence that 바카라사이트y really work.

What would you most like to see changed in university education?
For a century, ma바카라사이트matics was part of what was thought of as a liberal education. Calculus was 바카라사이트 first step into higher ma바카라사이트matics, and training people to know a little calculus was thought of as an important thing. These days, learning about statistics ¨C how to manipulate data, and how to understand when people are trying to pull 바카라사이트 wool over your eyes about data ¨C is much more important for being an educated citizen. I would hope that universities would think about including that not as a specialty, but as part of a liberal education.
