Describe value-added models (VAMs) and discuss the costs and benefits of using them to measure teacher impact on student performance? What are some alternative approaches to using VAMs and how can they be effectively employed? How are teachers evaluated in your district (or a district you know well)? To what extent does the evaluation system in this district seem effective to you? What are the best indicators of teacher effectiveness in your experience? How can these indicators be measured? Other than teacher effectiveness, what influences student achievement? To what extent can these influences be accounted for so that teacher effectiveness is measurable? Why might teacher effectiveness differ from class to class as well as from year to year or from test to test? What kind of performance assessments could teachers use to document their effectiveness? How would these be “scored”? What might be the role of a coach or mentor in terms of a teacher evaluation system? What might be the role of professional development?
