This study analyzed the instructional practices of more versus less effective U.S. History teachers identified by a multiple regression model. Using surveys, observations, and focus-group interviews, the study found that the most effective teachers had a more complete package of rigor, relevance, and relationship strategies than less effective teachers. Effective teachers had strong content knowledge, prepared their own materials, taught reading and note-taking skills, used time wisely, and connected history to themes across time. Relationships with students were of utmost importance to effective teachers. They gave frequent positive feedback and believed that all students could succeed. Effective teachers created an atmosphere of mutual respect, in which both teachers and students were enthusiastic. These results can be used to motivate teacher and school improvement efforts in a number of ways.
