Conceptions of ecological processes such as the flow of energy and cycling of matter in an ecosystem are increasingly important understandings in a rapidly changing world. This study utilizes a p-prims, or knowledge in pieces, lens to examine understandings and disconnections in students' conceptualizations of energy flow and matter cycling…

This research targets children's informal strategies and knowledge of fractions by examining their ability to create, interpret, and connect representations in doing and communicating mathematics when solving fractions tasks. Our research group followed a constant comparative method to analyze clinical interviews of children in grades 2-6 solving…

The majority of research concerning student veterans has been conducted at the university level, with minimum analysis performed at the level where the vast majority of returning veterans attend school: the community college. While some research has discussed what services colleges and universities should offer returning veterans, little research…

This dissertation is about the stories of African American male undergraduate students who have experienced success in mathematics. Bandura's (1997) social cognitive theory and Tillman's (2000) culturally sensitive research approach which promotes qualitative methods, recognizes ethnicity, and positions culture as central to the research were…

This phenomenological study of the lived experience of leadership emergence was initiated to answer the question, "Where does leadership come from?" Leadership emergence was explored as the result of a nexus of contextual and structural influences. In response to these questions, a sample of leaders from a metropolitan area in a…

This article extends the literature on teachers' career paths by attending to the experiences of educators when they were students in secondary classrooms. Grounded in the perspective that biography is central to teaching, we investigate undergraduate pre-service teachers' educational experiences, views on teaching and learning, and professional…

This study examined teachers' and students' initial conceptions of computer-based models--Flash and NetLogo models--and documented how teachers and students reconciled notions of multiple representations featuring macroscopic, submicroscopic and symbolic representations prior to actual intervention in eight high school chemistry…

As the USA experiences rapid growth of nontraditional adult students in higher education, educators and institutions will increasingly need to look beyond the traditional youth-centric educational models to better address adult learning needs. To date, no research has been conducted examining the learning experiences of adult students enrolled in…

This study addresses the problem of mathematics teachers' resistance to problem-solving models that align with constructivist perspectives because they feel pressure to utilize more teaching approaches that focus on preparing students for high-stakes tests. The purpose of this qualitative study was to explain how ninth grade mathematics students…

The author studied a public junior high school identified as successfully implementing authentic instruction. Such instruction emphasizes higher order thinking, deep knowledge, substantive conversation, and value beyond school. To determine in what ways higher order thinking was fostered both for students with and without disabilities, the author…

This study explored what cognitive resources (i.e., units of knowledge necessary to learn) first-semester organic chemistry students used to make decisions about acid strength and how those resources guided the prediction, explanation and justification of trends in acid strength. We were specifically interested in the identifying and…

By 2010, all children at Key Stage 2 in England will be entitled to learn primary foreign languages (PFL); indeed PFL is now set to become part of the core primary curriculum. This policy is not uncontroversial. A number of studies have established the high levels of motivation that can be engendered among younger learners of modern foreign…

This purpose of this study was to identify how adult ELL community college students perceive their experience in the development of academic literacy, specifically academic writing, and to explore their perceptions of the factors, attitudes, and experiences that have facilitated their development of that level of academic literacy. To address this…

Does speed provide a "model for" rate of change in other contexts? Does JavaMathWorlds (JMW), animated simulation software, assist in the development of the "model for" rate of change? This project investigates the transference of understandings of rate gained in a motion context to a non-motion context. Students were 27 14-15 year old students at…

Federal and state policies have long sought to address the social inequities faced by limited English proficient (LEP) students through the improvement of English language acquisition. English language acquisition policy has focused on access to resources, qualified teachers, and instructional methodologies (e.g. pedagogy) that create a learning…
