This dissertation contains findings from two research projects. The first research area focused on assessing engineering students problem solving skills. Problem solving related to two material and energy balance topics--vapor liquid equilibrium and reacting systems with recycle - were examined first followed by a more holistic analysis across two…

The aims of university System Dynamics (SD) programs include the mastery of systems thinking skills, modeling skills, and/or application to solving real-world, dynamic, complex problems. Existing research has articulated learning sequences of what learners should know and be able to do, and when. It is called the competence development framework…

This study explores how children from two to nine years of age develop Computational Thinking (CT) skills. The term "CT" denotes a set of cognitive processes that are useful for framing and solving problems using computers and other information processing agents. Acquisition of CT skills is traditionally associated with learning to code…

This dissertation comprises two articles. In the first article, I review and synthesize literature on how prospective teachers (PTs) might evaluate students' mathematical thinking as manifested in written work. After defining evaluation, I argue that evaluating students' thinking in productive ways is both necessary and desirable within the…

Prior Learning Assessment (PLA) is a term for various methods by which universities accredit student experiential learning. One such method is the academic portfolio, a written reflective process in which students demonstrate that their personal or professional learning fulfills university outcomes. Proponents of academic portfolios claim that…

There is little empirical research related to how elementary students develop computational thinking (CT) and how students apply CT in problem-solving. To address this gap in knowledge, this study made use of learning trajectories (LTs; hypothesized learning goals, progressions, and activities) in CT concept areas such as sequence, repetition,…

Inquiry-oriented teaching is a specific form of active learning gaining popularity in teaching communities. The goal of inquiry-oriented classes is to help students in gaining a conceptual understanding of the material. My research focus is to gauge students' performance and conceptual understanding in inquiry-oriented linear algebra classes. This…

Traditional teacher education programs focus on pedagogy and, to a lesser extent, assessments of knowledge (Siedlecki, 2012). Pedagogy and assessments should be fundamental components of any secondary teacher's curriculum planning (Knight, Shum, & Littleton, 2014). This study sought to consider the possible effects of three pedagogical…

This case study examined competence in two third-grade classrooms where teachers centered children's mathematical thinking in instructional decision-making. Offering a synthesis of sociocultural characterizations of competence, and drawing from a variety of data sources including classroom video, student work and assessments, and teacher…

Within the confines of this study, the researcher investigated Project Lead the Way (PLTW) Engineering curriculum goals within Missouri high schools. The study measured Missouri PLTW teachers' perceptions of various elements of the curriculum as well as state and national PLTW End of Course student assessment data to determine if a relationship…

With the adoption of the National Common Core State Standards in Mathematics (CCSSM) in many states and the lack of understanding and strategies to implement the new standards by classroom teachers, implementing effective professional development is vital. The focus of this qualitative case study was to provide insight into elementary school…

In the engineering profession, one of the most critical skills to possess is accurate and efficient problem solving. Thus, engineering educators should strive to help students develop skills needed to become competent problem solvers. In order to measure the development of skills, it is necessary to assess student performance, identify any…

Researchers have suggested that teachers use a specialized type of knowledge specifically attributed to the work of teaching. One aspect of this specific type of knowledge is the ability to analyze children's work. With continued emphasis on a teacher's ability to analyze their students' thought processes, teacher candidates will need to develop…

Many schools have adopted programming designed to promote students' behavioral aptitude. A specific type of programming with this focus is School Wide Positive Behavior Supports (SWPBS), which combines positive behavior techniques with a system wide problem solving model. Aspects of this model are still being developed in the research…

Mathematics, in general, and algebra courses, in particular, have been categorized as "gatekeepers" for higher education, better jobs, and even citizenship. For many low-income and working adults, community college is the institution where they choose to develop their mathematics understanding so they can pursue their dreams.…
