Thesis (Ph.D.)--Michigan State University, 2004.

It is desirable for many measurement applications, particularly in education, to have developmental scales that span wide developmental levels for the purpose of modeling growth. Many test companies provide such scales and claim they are adequate for growth modeling. However, scales spanning wide grade ranges also span wide content ranges. This shift in the constructs being measured from grade to grade jeopardizes the validity of inferences and interpretations made from growth models based upon developmental scales. It is shown how observed growth trajectories, the magnitude of effects on growth, and the ability to detect statistically significant effects on growth are affected by construct shift. It is shown how construct shift may cause distorted results in educational experiments, quasi-experiments, correlational studies, and accountability analyses. These distortions may be understatement or overstatement of effects on initial status or growth, detection of an effect when there is none, failure to detect a true effect, attribution of effects on initial status to effects on growth, attribution of effects on growth to effects on initial status, identification of highly effective teachers as ineffective simply because their students achievement is outside the range of achievement measured well by a given grade-level test, and the attribution of prior teacher effects to current teachers. Therefore, theories and policies based upon studies of growth that use developmental scale scores are likely to be invalid because of distorted conclusions about the shape of growth trajectories, about the effects of interventions on growth, about the effects of environmental variables on growth, or about educator effectiveness in eliciting growth.
