Featured in Graduate Studies
Increasingly, we are finding teachers and school leaders using Exemplars as part of their research in graduate courses, or as part of their theses. Our goal is to feature as many of these as we possibly can.
If you are using Exemplars as part of a graduate course as a thesis, please let us know.
In summarizing her findings, Dr. Judy Devens-Seligman, Principal at Wing Lane Elementary School in Valinda, CA, writes:
As a result of the classroom exposure to mathematics problem solving, students who participated in this study appeared to have broadened their knowledge about problem-solving strategies. For the teachers and students who made up the comparison groups, there was recognition that problem solving emphasizes and develops a different type of thinking than most textbook lessons and follow-up problems.
With increased exposure to problem solving, students who participated in the treatment group learned the value of knowing more than one way to approach a problem, they developed their own preferences for the way they liked to work on difficult problems, they learned ways to communicate their thinking to peers, and in many instances to evaluate what they did and didn't understand about the mathematics inherent to the problem.
Ben Hartman, a teacher at Cedar Elementary in Gwinnett County, Georgia, was concerned about performance in problem solving at his school. He asked if using Exemplars on an almost weekly basis between October and March would improve student performance the Georgia Criterion-Referenced Competency Tests (CRTC) and on Exemplars problems.
Ben found that growth on the CRCT was substantial. Before using Exemplars, nearly 20% of students did not meet the Georgia standards. After problem solving, all students met the standard. Before using Exemplars only 6% of students exceeded the standard, afterward more than one-third (37%), exceeded the standard.
Kathy Spruiell was a math specialist and instructional math coach in 75 classrooms at Simonton Elementary in Gwinnett County, Georgia. Her experience led her to wonder if using a meta-cognitive approach and peer reflection would lead to improved performance in problem solving in a first-grade classroom.
Kathy used Exemplars problems to teach students to use meta-cognitive and peer-reflection approaches as well as for pre- and post-assessments. To gain pre-test scores, an average was taken of students' Exemplars solutions to problems already solved. Post-test scores came from Exemplars solutions students completed after using these approaches.
In reviewing her data, Kathy commented, "I was actually surprised at the gains the students were able to make in a relatively short amount of time."
Steve Weiss was formerly a fourth-grade teacher at the Palmer Lake Elementary School in Palmer Lake, Colorado. As part of his MAT program in Integrated Natural Sciences at Colorado College, Steve conducted an Action Research Project on the effect of using science notebooks (journals) and formative assessment to improve student performance.
Steve used Exemplars as both his means of instruction as well as his instrument for the pre- and post-assessments. He found that in the beginning his students were very challenged, but that formative and peer assessment and using science notebooks led to significant improvement in performance.
