A focus of reforms in standards, learning environments, teacher preparation programs and professional development is to support teachers' and students' engagement with scientific practices such as argumentation, modeling and generating explanations for real-world phenomena (NRC, 2011).

This dissertation investigates how discourse-pragmatics informs children's choice of referential forms. Three studies utilizing naturalistic data examine the role that six discourse-pragmatic features play in the acquisition of referential forms in a non-null subject language, English. The influence of child-directed speech on development is also…

This dissertation investigates several topics in the morphology, syntax and semantics of the Nez Perce verb and verbal clause. The first part of the dissertation focuses on the morphological segmentation of the Nez Perce verb and on the semantic description of the verb and clause. Chapter 1 provides a grammar sketch.

A growing body of literature has provided evidence of the contribution of various metalinguistic skills to children's English literacy development; however, most of the studies focused on reading outcomes while spelling outcomes have been under-researched. Further, very few studies have been conducted to investigate if the results based on native…

This dissertation proposes a new factor-analytic technique for detecting cheating on exams. Person-fit statistics have been developed to assess the extent to which examinees' response patterns are consistent with expectation, with expectation defined in the context of some model. Response patterns that are inconsistent with expectation are said to…

The purpose of this study was to examine the effects of performance-contingent rewards in a real-world setting, namely the sixth grade math classroom. This study is significant in that it represents a field study on the effects of rewards in the classroom. The purpose of this study was to investigate what effect, if any, the choice of a reward had…

I began this study with two assumptions. Assumption 1: Study quality matters. If the means by which researchers design, carry out, and report on their studies lack in rigor or transparency, theory and practice are likely to be misguided or at least decelerated. Assumption 2 is an implication of Assumption 1: Quality should be measured rather than…

One area of health promotion research rich with potential for both theoretical and empirical investigation is the "entertainment-education" (EE) strategy. Though a growing body of evidence points to the effectiveness of the EE strategy, further investigation is needed to explore the underlying cognitive and affective processes that make EE an…

When test forms are administered to examinee groups that differ in proficiency, equating procedures are used to disentangle group differences from form differences. This dissertation investigates the extent to which equating results are population invariant, the impact of group differences on equating results, the impact of group differences on…

Scope and Method of Study: The study investigated the relationship between performance on the Oklahoma State Testing Program (OSTP) for grades 3-7 and the EXPLORE in math and reading for 586 students. The EXPLORE test, a part of the ACT, is given in the eighth grade and provides college readiness benchmarks and a national percentile ranking (NPR)…

One of the educational reform methods sanctioned under No Child Left Behind legislation is the development of charter schools (King, 2007).
