At the University of Nebraska-Lincoln, the Instructional Staff Development Program, Component VI, Developing/Modifying Student Affective Behaviors focuses upon some affective behaviors that promote and are considered vital to the inquiry process. Through teachers trained in the development of affective behaviors, this program has achieved changes in student attitudes as measured both by attitude inventories and by direct observations. Teachers and students increased their use of affective behaviors. Teachers asked more affective questions and spent more time building on student ideas after instruction. Teacher talk decreased to only 14.3% of the total interaction with approximately 7% of that in the category of positive reinforcement. (Author)
