Developing an Aggregate Metric of Teaching Practice for Use in Mediator Analysis
Lazarev, Valeriy; Newman, Denis; Grossman, Pam
Society for Research on Educational Effectiveness
Efficacy studies of educational programs often involve mediator analyses aimed at testing empirically appropriate theories of action. In particular, in the studies of professional teacher development programs, the intervention targets presumably teacher performance while the ultimate outcome is the student achievement measured by a standardized test. The main objective of this study is to develop a methodology for creating an optimal aggregate teacher performance metric from domain scores for use as mediators in the analyses of student outcomes. The authors use one particular observation rubric, PLATO, to answer the question of how an aggregate teacher performance metric can be constructed from domain scores that would be best aligned with a selected measure of student achievement. The preliminary analysis determined that only three out of six domains of PLATO used in the study were significantly associated with the value-added measure of student achievement. Of the three significant domains, two had linear relationship with the value added. For the only domain with non-linear relationship, log transformation appeared to be sufficient to linearize the relationship. A figure is appended.
