Science Students Benefit from Teachers' Research Experience

When high school and middle school science teachers engage in extracurricular research work, their students benefit. That's the result of a new study published in Science last week by researchers at Columbia University. In addition, they found that such extracurricular research work can also bring economic benefits to schools and communities.

The research, funded in part by the National Science Foundation, focused on middle school and high school teachers in New York, who engaged in a program called the Columbia University Summer Research Program for Secondary School Science Teachers (CUSRP). The research team, led by Samuel C. Silverstein, evaluated the performance of their students over the course of several years following the completion of the program. They found a definite, statistically significant benefit for the students of the teachers who participated in the program, but only after a delay of a couple years.

This delay, Silverstein said, may explain why similar benefits have not been reported from other science teacher summer research programs: Evaluations of the results were too short-term.

As Silverstein explained in an interview with the NSF: "Science work experience programs for teachers or research experience programs for teachers are rarely funded for a significant period of time.... Secondly, the funders rarely provide the kind of support that is necessary in order for these programs to do the kind of evaluation--in depth evaluation--that's necessary to find out what's going on. And third, it takes several years for a teacher who learns new teaching techniques and who learns to use new equipment and new devices in the classroom to actually implement that in the classroom and implement it successfully." (This interview can be viewed on NSF's press site here.)

He said many such programs may have been more successful than previously thought; there just wasn't the proper evaluation to determine the actual, longer-term success of the programs.

"You'll notice in the Science paper," he said, "that the data only become statistically significant in the third and fourth years after teachers complete the program. Now we see incremental differences in the first and second year after entering the program, and the third and fourth years after entering the program are where the statistically significant outcome data are found."

In the case of the CUSRP (a two-year program), the researchers looked at New York State Science Regents Examination results for students of teachers who participated in the program and compared them with the results for students whose teachers did not participate. Prior to entry in the program, students of CUSRP teachers performed lower than students of non-CUSRP teachers. But three years after the program, there was a greater than 10-point difference in pass rates between the two groups--61 percent for students of CUSRP teachers versus 50.2 percent for students of non-CUSRP teachers. (Data included 7,259 students of CSURP students and 36,101 students of non-CUSRP students from 1994 to 2005.)

 

Silverstein pointed out that the benefits did not arise from specific knowledge gained by participating teachers but rather by the "generic things about dong science" that the teachers picked up in their experiences, "about the importance of doing hands-on science, about the importance of understanding the technologies of science so that you can actually ask yourself, 'Gee, if I had to solve that question or problem, what technologies would I use? How would I prove that?' It has to be that they learned a new way of responding to students."

The researchers also explored the economic benefits of the program and estimated that for every dollar spent on the program by sponsors, the New York Department of Education receives back $1.14 within four years through a combination of "increased teacher retention and decreased need for students to repeat coursework," according to NSF. Further, economic benefits may also be realized through increased graduation rates.
