Students come to their high school physics classroom with experiences and knowledge that can be used to help explain physics concepts, but those experiences may not fully align with the scientifically accepted science concept. When there is a misalignment between a student's prior knowledge and the scientifically accepted concept a misconception…

Extant literature lacks an explanation of the thought processes used by secondary school science teachers to interpret students' scientific models that are comprised of drawing activities. In this exploratory study, a constructivist grounded theory (CGT) was developed to generate an interpretive understanding. The CGT was generated from…

Measurement is an important concept in school mathematics (Clements, 2003). There are several studies and empirical evidence on students' thinking about geometrical measurement of length, area, and volume (e.g., Barrett et al., 2017; Battista, 2007, 2012; Eames, 2014; Lehrer, Jenkins, & Osana, 1998; Miller, 2013; Outhred & Mitchelmore,…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

The most recent science education reform, the Next Generation Science Standards (NRC, 2012) set forth a new and ambitious agenda for science education. These standards go beyond all of the previous versions and combine three dimensions: disciplinary core ideas, science practices and crosscutting concepts. They call on teachers to recognizing and…

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students' ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type…

The Next Generation Science Standards propose a multidimensional model of science learning, comprised of Core Disciplinary Ideas, Science and Engineering Practices, and Crosscutting Concepts (NGSS Lead States, 2013). Accordingly, there is a need for student assessment aligned with the new standards. Creating assessments that validly and reliably…

Although a large part the Physics Education Research (PER) literature investigates students' conceptual understanding in physics, these investigations focus on qualitative, conceptual reasoning. Even in modeling expert problem solving, attention to conceptual understanding means a focus on initial qualitative analysis of the problem; the equations…

The purpose of this study was to investigate the instructional effectiveness of animated signals among learners with high and low prior knowledge. Each of the two treatments was presented with animated instruction either with signals or without signals on the content of how an airplane achieves lift. Subjects were eighty-seven undergraduate…

This study examined the relationships among visuospatial ability, motivation to learn science, and learner conceptions of force across commonly measured demographics with university undergraduates with the aim of examining the support for an evolved sense of force and motion. Demographic variables of interest included age, ethnicity, and gender,…

This dissertation explored beliefs about learning from multiple related visual representations in science, and compared beliefs to learning outcomes. Three research questions were explored: 1) What beliefs do pre-service teachers, non-educators and children have about learning from visual representations? 2) What format of presenting those…

This thesis explores the role of multiple representations in introductory physics students' problem solving performance through several investigations. Representations can help students focus on the conceptual aspects of physics and play a major role in effective problem solving. Diagrammatic representations can play a particularly important role…

This research used an evidenced-based experimental 2 x 2 factorial design General Linear Model with Repeated Measures Analysis of Covariance (RMANCOVA). For this analysis, time served as the within-subjects factor while treatment group (i.e., static and signaling, dynamic and signaling, static without signaling, and dynamic without signaling)…

Research examining animation use for student learning has been conducted in the last two decades across a multitude of instructional environments and content areas. The extensive construction and implementation of animations in learning resulted from the availability of powerful computing systems and the perceived advantages the novel medium…

Much research in educational technology has focused mainly on how the technology supports student learning. Research on what teachers need to know in order to appropriately incorporate technology into their teaching has been limited because of the lack of theoretical grounding for understanding teachers' cognitive process of technology integration…
