In this dissertation we examine several issues related to the retention of under-represented minority students in physics and science. In the first section, we show that in calculus-based introductory physics courses, the gender gap on the FCI is diminished through the use of interactive techniques, but in lower-level introductory courses, the gap…

How do you dynamically customize the programming language available in a context within an existing system, without changing the underlying system? This dissertation introduces a language design approach that addresses this problem. The basic idea is to structure programs as systems of multiple interacting levels of abstraction, where all of the…

Presently, research is questioning the value of homework, especially at the elementary level. One reason homework is considered important is that it allows for the opportunity to practice and reinforce skills. Currently, elementary students in the United States are assigned homework in mathematics three or more times a week. Since homework…

Using a multiple-gating procedure, 5 research sites (3 elementary and 2 middle schools) were identified as implementing a Response to Intervention (RTI) framework. This study uses a multiple case study design to describe the RTI implementation in reading at these 5 sites. Findings suggest that the sites studied are utilizing a hybrid model (a…

In this dissertation, I present my attempts at designing an elementary mathematics methods course to support prospective teachers in developing an understanding of how to teach all students in learning powerful mathematics. To do this, I introduced them to teaching mathematics for equity and social justice by discussing ways to support students'…

This study's purpose was to explore effectiveness of alternate format in-service delivery for what teachers needed to know to effectively teach their students with Autism Spectrum Disorder/High Functioning Autism/Asperger Syndrome (ASD/HFA/AS) in the general education setting. The study's research questions included: Did participants learn…

This study sought to determine the degree to which a body of successful supervision attributes actually exists in practice. Specifically, this investigation sought to determine: (1) To what extent are the twelve dimensions of supervisory practice from the 1989 ASCD Study currently being practiced among selected instructional leaders in two…

The purpose of this study was to gather teacher and student perceptions of the educational benefits that emerge from providing diverse learning environments for students attending an inter-district magnet school. Research Questions were (1) In what ways do teachers and students report that the magnet school offers an ethnically diverse learning…

This program evaluation study examined the relationship between Problem Solving/Response to Intervention (PS/RtI) training and technical assistance and educator and implementation outcomes following the first year of a 3-year project. Educators from 40 pilot schools in eight districts participating in the study received ongoing professional…

This study examined teachers' positioning of English language learners (ELLs) and instructional strategies to support them within the Problem Solving Cycle professional development program. Using a communities of practice lens (Wenger, 2000) and building on literature related to supporting ELLs in mathematics, Mathematics Knowledge for Teaching…

A schema-based instruction allows students to approach a mathematics problem by focusing on the underlying semantic or problem structure, thus facilitating conceptual understanding and adequate skills. The purpose of this study was to examine the effectiveness of schema-based intervention on the mathematical word problem solving skills of middle…

Problem solving can be thought of in two phases: the first phase is problem formulation and the second solution development. Problem formulation is the process of identifying a problem or opportunity in a situation. Problem Formulation Ability, or PFA, is the ability to perform this process. This research investigated a method to assess PFA and…

The purpose of this study was to assess algebra and geometric prerequisites skills as incorporated into the Applied Calculus Optimization Problem (ACOP) solution. The difficulties that students encounter in applying algebraic and geometric prerequisites at the early stages of the ACOP solution were identified. The study analyzes errors related to…

This study explores social interaction and mathematics performance, especially regarding how bilingual Latino/a students' positioning and participation evolved as they interacted with others in mathematics problem solving. Historically, Latinas/os have faced segregation in different ways that affect the quality of their social interactions…

"Fortune" magazine's articulation of productivity during the period 1969 to 1972 was a skillfully crafted work of propaganda that mixed public perception about (a) the younger generation, (b) issues about the growing rate of inflation, (c) shifting employment sectors, (d) increasing nominal wages, and (e) declining rate of profit.…
