What is mathematics? What does it mean to be a mathematician? What should students understand about the nature of mathematical knowledge and inquiry? Research in the field of mathematics education has found that students often have naive views about the nature of mathematics. Some believe that mathematics is a body of unchanging knowledge, a…

Many important real-world decision-making problems involve group interactions among individuals with purely informational interactions. Such situations arise for example in jury deliberations, expert committees, medical diagnoses, etc. We model the purely informational interactions of group members, where they receive private information and act…

When a new student comes to play an educational game, how can we determine what content to give them such that they learn as much as possible? When a frustrated customer calls in to a helpline, how can we determine what to say to best assist them? When an ill patient comes in to the clinic, how do we determine what tests to run and treatments to…

Most decision analysis techniques are not taught at higher education institutions. Leaders, project managers and procurement agents in industry have strong technical knowledge, and it is crucial for them to apply this knowledge at the right time to make critical decisions. There are uncertainties, problems, and risks involved in business…

In this collective instrumental case study, the focus was on understanding the issue of Intercultural Competence within Saudi academic migrants. The purpose of this study was to determine how Saudi academic migrants gain intercultural competence through the development of attitudes, knowledge, and skills, as defined by Deardorff's (2006) process…

The purpose of this heuristic case study, also informed through the tradition of critical systems theory was to explore elementary principals' "voices" in instructional decisions made by central office administrators at a large suburban school district in a Midwestern State. Six elementary principals were interviewed for this study.…

Objective: A series of four studies explored the heuristic value of a method of grouping students in counseling by the severity of symptoms across eight domains. Method: Participants were over 50,000 college students in counseling, assessed with the CCAPS-62 and -34 as part of routine clinical care. Latent Profile Analysis was used to group…

The past two decades have shown an unexpected effectiveness of "Web-scale" data in natural language processing. Even the simplest models, when paired with unprecedented amounts of unstructured and unlabeled Web data, have been shown to outperform sophisticated ones. It has been argued that the effectiveness of Web-scale data has…

The basis for evaluating projects in an organizational IT project portfolio includes complexity factors, arguments/criteria, and procedures, with various implications. The purpose of this research was to develop a conceptual framework for IT project proposal evaluation. The research involved using a heuristic roadmap and the mind-mapping method to…

The purpose of this heuristic study was to explore the ways in which spirituality informed and impacted educators' own experience of learning as a transformative inner encounter. It inquired into the experience of learning from a spiritual perspective in order to determine the extent to which transformative learning could be described as a…

Though research in emerging technologies is vital to fulfilling their incredible potential for educational applications, it is often fraught with analytic challenges related to large datasets. This thesis explores these challenges in researching multiuser virtual environments (MUVEs). In a MUVE, users assume a persona and traverse a virtual space…

The purpose of this study was to develop an instructional theory for using a class wiki to support collaborative learning in higher education. Although wikis have been identified in theory as one of the most powerful emerging technologies to support collaborative learning, challenges have been revealed in a number of studies regarding student…

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…

This dissertation reports on a study investigating the identity of first-year university students as writers. The longitudinal project explored how students from educationally disadvantaged backgrounds construct their identities as undergraduates and as academic writers in their first year. The research was qualitative and interpretative, and used…

This dissertation addresses theory and practice of evaluation and assessment in university student affairs, by applying logic modeling/program theory to a case study. I intend to add knowledge to ongoing dialogue among evaluation scholars and practitioners on student affairs program planning and improvement as integral considerations that serve…
