Presented in this report are the results of the feasibility testing of selected micro-teaching and video recording feedback techniques in a laboratory setting designed to simulate vocational teacher education. Volunteer teachers were selected and randomly assigned to three treatment groups in a repeated measurement design to compare the relative…

A latent trait model is described that is appropriate for use with tests that measure more than one dimension, and its application to both real and simulated test data is demonstrated. Procedures for estimating the parameters of the model are presented. The research objectives are to determine whether the two-parameter logistic model more…
