Finding What Works in the Classroom 2.24.11

Teachers want to know what works in the classroom to facilitate student learning and to achieve growth in their learning. The research-based document,What Works in Classroom Instruction by Robert Marzano, Barbara Gaddy, and Ceri Dean (,  is a good resource which explains the research behind classroom strategies and their effect. The effect sizes of various strategies range from .59 to 1.61. An effect size of 1.0 is roughly equivalent to one year’s growth in achievement. Please refer to the above article for a table of strategies and effect sizes.

Strategies that were found to strongly affect student achievement include homework and practice, setting goals and providing feedback, non-linguistic representation, summarizing and note-taking, identifying similarities and differences, cooperative learning, reinforcing effort and providing recognition, generating and testing hypotheses, and activating prior knowledge. The two highest effect sizes fell in the strategies of summarizing and note-taking and identifying similarities and differences. This site has helpful information about using these strategies.

Part of my job as the Target® 2011 Iditarod Teacher on the Trail™ is giving presentations to students in Alaska schools. I started those today.  The presentation gives students a chance to learn aboutsome  similarities and differences of Alaska and North Carolina. Letting students use a Venn diagram, Thinking Maps (double bubble or bubble maps) or write about the differences and similarities of the two states would be methods to carry out a strategy with a high effect size.

The Iditarod Race is a tool to use to create a lesson on note-taking and summarizing or on identifying similarities and differences. Perhaps your area has a sport or race which could be compared and contrasted with the Iditarod, or watch Iditarod Insider video clips to practice taking notes and then organizing those notes into categories. Maybe those categories could be more easily remembered by using non-linguistic representation, another strategy which can positively affect student learning.
