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). Engaging in these practices in authentic ways…

This applied dissertation was designed to provide perceptual teacher data as well as summative testing data to educational leaders concerning the effects of implementing Investigations in Number, Data, and Space® (Investigations) in three Title I elementary school settings, two Title I schools, and one non-Title I school. Data collected during…

This investigation examined the transition from a spiral science curriculum to a field-focus science curriculum in middle school. A spiral science curriculum focuses on a small part of each field of science during each middle school year, more of a general science concept. In contrast to that, the base of a field-focus curriculum is that each…

Motivation is an important topic of concern for teachers. A review of motivation research, though, revealed that students have been the focus of motivation research. When teachers have been included in studies, researchers have asked teachers to evaluate specific students, compared teacher and student perception of the same phenomena, or asked…

Achievement goal theory is considered to be a well-researched field. However, this research has been primarily through surveys, and not enough attention has been paid to the cognitive aspects of how children perceive goals. Additionally, the mastery-avoidance construct is relatively new to the achievement goal literature, with little research to…

The purpose of this mixed methods study was to investigate urban middle school teachers' descriptions of their competency in the current National Education Technology Standards for Teachers (NETS-T). The study also investigated how urban middle school teachers currently use technology to support their teaching and student learning. Research…

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…

School safety is a very important issue for school staff, parents, and students. When school safety is lacking, students suffer in emotional, academic, and social areas. One recent intervention middle schools are examining is the student uniform policy. In some cases, school uniforms have been shown to have a profound effect on school safety,…

School effectiveness and instructional leadership research over the past thirty years have largely concluded that principal effects on student achievement are small and indirect; it has been assumed that principal effect is important, but mediated through other school factors. To the contrary, this experimental study found that one-on-one…

Virtual reality (VR) is increasingly used to acquaint geoscience novices with some of the observation, data gathering, and problem solving done in actual field situations by geoscientists. VR environments in a variety of forms are used to prepare students for doing geologic fieldwork, as well as to provide proxies for such experience when…

One of the educational reform methods sanctioned under No Child Left Behind legislation is the development of charter schools (King, 2007). While many studies have focused on comparing the student academic achievement rates of charter schools to traditional public schools, little empirical research exists comparing student academic achievement…

This study investigated the attitudes of administrators about differences and similarities between middle and high school teachers. The research question that guided the study was, "Do attitudes about what makes an effective educator differ between building administrators at the middle and high school levels?" A formal, sequential, mixed-methods…

\The purpose of this study was to investigate population invariance of the true-score linking functions with respect to the ability subgroups (i.e., average-achieving students, low-achieving students, and students with learning disabilities). The mean/mean linking functions for five alternate forms of a curriculum-based math problem solving…

Classroom teachers draw upon a variety of discourses to understand and make decisions about the students they teach. This case study investigation explored the discourses at work in inclusion classrooms, with particular attention paid to the way in which discourses may impact the problem of overrepresentation in special education. Frameworks that…

Students' scientific investigations have been identified in national standards and related reform documents as a critical component of students' learning experiences in school, yet it is not easy to implement them in science classrooms. Could science demonstrations help science teachers put this recommendation into practice? While demonstrations…
