Abstract:
Measurement issues that arise in a two-stage teacher evaluation for an outstanding faculty award are addressed. A teacher evaluation inventory with ten Likert-type items was developed. Thirty college teachers were rated by 293 students on the new inventory. The facet Rasch technique was applied to analyze the test data, and the items fit the Rasch models fairly well. The separation reliability for the teachers is.98, indicating that the items together with these students can differentiate the teachers extremely well. A cut score was set to.80 logits so that only those teachers with efficacy estimates above that level are eligible to apply for the award. A short version containing only half of the items was also developed.
