Career centers in higher education must create environments that serve the needs of students and alumni. Alumni not only are a served population, but also are beneficial to student career development, and serve dual purposes as clients and volunteers. One program frequently offered by career centers that engages alumni volunteers is an alumni mock…

If we want mathematics education to be valuable to everybody, including those who do not pursue mathematics-related careers, we need to use mathematics as a training ground for certain ways of thinking. This dissertation focuses on one aspect of mathematical thinking, namely theory building. It has three parts -- unpacking what constitutes theory…

In multisite experiments, we can quantify treatment effect variation with the cross-site treatment effect variance. However, there is no standard method for estimating cross-site treatment effect variance in multisite regression discontinuity designs (RDD). This research rectifies this gap in the literature by systematically exploring and…

This Educational Leadership Portfolio (ELP) reviews the state of online learning at the University of Delaware (UD). UD lacks the sufficient infrastructure and resources to support online learning, despite its steady growth in online enrollments over the past decade. This growth was punctuated with a spike in online enrollments due to the pivot to…

The mission of high school career and technical education (CTE) programs is to prepare high school graduates for a career. This study provides insight into the educational practices that support students with the skills necessary for workplace success, as not all CTE program graduates are prepared for the workplace with industry-ready skills. The…

Background: Researchers are often interested in testing the effectiveness of an intervention on multiple outcomes, for multiple subgroups, at multiple points in time, or across multiple treatment groups. The resulting multiplicity of statistical hypothesis tests can lead to spurious findings of effects. Multiple testing procedures (MTPs)…

Education researchers frequently have to choose between statistical models for their data, and in many cases the candidate models or parameters can be listed in a sequence, m=1,...,M, from less preferable choices to more. For instance, in choosing a bandwidth for regression discontinuity designs, researchers would favor the largest possible…

Although using specific guidelines to structure course participation in online courses can boost learner engagement, research suggests that learners' overreliance on these standards can lead to superficial participation. As a result, alternative methods for participation assessment, such as ungrading or self-assessment, are increasingly being…

Most of the prior research concerning instructional design (ID) education has taken place in the context of introductory courses. However, teaching advanced ID students differs from teaching novices because advanced students are capable of independent action, but also still need some targeted instruction to develop their own design skills and…

Virtual reality (VR) technology is playing a crucial role in the changing paradigm of education. In many cases, however, VR technology is not being taught because of the lack of relevant educational content at middle and high school levels. This study investigates the effect of design education using VR-based coding on students' competence and…

As the number of online courses increase in higher education, many higher education institutions outsource online course development to an Online Program Management (OPM) provider because of a lack of budget, staff, and technology. Current research indicates that OPM providers often do not have instructional design (ID) services tailored to a…

This study explored the research question: How can project-based inquiry (PBI) in STEM teaching be designed, planned, and implemented in two preschool settings? A case study was conducted, using a collaborative action research approach. This research was conducted with 11 teachers and 300 children from 11 classes at two preschools in Taiwan. The…

This article discusses some implications of working supportively with art and design students who manage mental health conditions in a postgraduate environment in a New Zealand University. The paper begins with a discussion of contesting research that considers relationships between highly creative thinkers and certain mental health conditions. It…

Multi-User Virtual Environments (MUVEs) provide a rich and immersive context for introducing inquiry-based and Problem-Based Learning (PBL) into science classrooms. MUVES can have a significant effect on learning outcomes, however, illuminating how particular design features interact with those outcomes is an important area of investigation for…

The aim of this pre-experimental study is to evaluate the acquisition level of counting skills of a 3-year-old classroom made up of 14 children through a specific instructional design. To this end, an instructional proposal to improve these mathematical skills was designed. Before and after the intervention, we measured the students' level…
