Instructional strategies in science that fail to identify students' initial understanding of scientific concepts may leave students' flawed ideas unchanged, thus affecting their ability to synthesize, differentiate, and connect to new information in science. The purpose of this quantitative study was to examine the relationship between concept…

The purpose of this research was to examine the patterns and themes of litigation in Americans with Disabilities Act (ADA) disability discrimination cases charged under the theory of disparate impact. Specifically, this study used Computer Assisted Legal Research (CALR) to identify and review all U.S. Appellate Court ADA disparate impact cases as…

This dissertation examines linguistic spatial frame of reference (FoR) usage across three cohorts, detailing the lexical and structural realization of particular spatial FoR classes within each linguistic community, as well as which linguistic and nonlinguistic factors are predictors of spatial FoR class usage. This study was designed to determine…

The purpose of this methodological study is to explore how well a process called "concept mapping" (Trochim, 1989) can articulate the theory which underlies a social program. Articulation of a program's theory is a key step in completing a sound theory based evaluation (Weiss, 1997a). In this study, concept mapping is used to…

Although young children are major audiences of science museums, limited evidence exists documenting changes in children's knowledge in these settings due in part to the limited number of valid and reliable assessment tools available for use with this population. The purposes of this study were to develop and validate a concept mapping assessment…

The purpose of this study was to explore perceptions of teachers who participated in professional learning communities, and the relationship of that participation to collaboration and co-teaching. Semi-structured interviews were employed to understand the perceptions of high school teachers who actively participated in PLCs with the goal of…

The purpose of this study was to assess the effects of node-link mapping on students' meaningful learning and conceptual change in a 1-semester introductory life-science course. This study used node-link mapping to integrate and apply the National Research Council's (NRC, 2005) three principles of human learning: engaging students' prior…

Diverse types of intimate committed relationships, namely cohabiting same-sex and opposite-sex partnerships, are increasingly prevalent in the United States (Bumpass & Lu, 2000; Garber, 2005; U.S. Census Bureau, 2000). Given the rise in the number of individuals participating in intimate committed relationships outside of the marital context,…

There are many perceptions of what should be taught in the social studies classroom. With the expansive amount of information that must be transferred to students, the job of the social studies teacher is becoming more challenging. To assist with this issue, there are numerous instructional strategies that can be employed such as anticipation…

Analogies are ubiquitous during instruction in science classrooms, yet research about the effectiveness of using analogies has produced mixed results. An aspect seldom studied is a model of instruction when using analogies. The few existing models for instruction with analogies have not often been examined quantitatively. The Teaching With…

Abundant research and literature suggest the unreflective use of PowerPoint (PPT)-type presentations to deliver core content in higher education classes may have a negative effect on student learning (Driessnack, 2005; Kinchin et al. 2008; Maxwell, 2007). Many students rely heavily on downloadable notes from electronic delivery to the exclusion of…

The role of Israel in the identity of North American Jews is of concern and interest to community leaders, philosophers of Jewish education, and most important, practitioners in the field. Although there is an awareness of the need to help emerging Jewish educators grapple with the complex questions surrounding Israel engagement, little research…

This qualitative study examines first-year college students' online search habits in order to identify patterns in millennials' mental models of information retrieval. The study employed a combination of modified contextual inquiry and concept mapping methodologies to elicit students' mental models. The researcher confirmed previously observed…

A universal problem to our society is the dramatic increase in the number of security threats, risks, and vulnerabilities to our nation's computer systems, data, and infrastructure. Our future success depends upon the problem-solving and thinking abilities of professionals entering the Information Assurance and Security (IAS) field. These…
