After briefly describing current educational research, the author then lists research-based recommendations to improve teacher performance evaluation. Offered are a list of steps to take in teacher evaluation, a sample list of evaluation criteria and a response mode, criteria for lesson analysis, a preobservation conference checklist, two approaches to classroom observation, recommendations regarding planning for the observation, and tips on the conduct of the appraisal interview. The author offers recommendations for writing the evaluation report, based not on research but on his own experiences. Finally, recommendations for setting job improvement targets are given. Companion documents list teacher evaluation performance areas, criteria, descriptors, and response modes used in the project. (Author/JM)
