Personalized learning, which has the potential to raise student achievement, requires understanding the competencies of students. Visualizations can help provide this understanding. Jeon et al. (2021) presented a latent space model that creates interaction maps visualizing response patterns from item response data. My dissertation proposes…

A major concern of online learning is the absence of face-to-face student-instructor interaction and student-to-student interaction, leading researchers to examine practical approaches to keep students engaged in the online learning environment. Synchronous methods have become a growing opportunity for student engagement in the online environment.…

With the advancement of technology, more and more degree programs are available in the form of online education. Despite its top ranking in online bachelor's degree programs, Pennsylvania State University's World Campus presents a variety of challenges and opportunities related to students' experiences, feelings, and operation as a…

Mathematics classrooms have reflected little change over the past century, consisting of the learning of inert, disjoint procedures with few connections between mathematics concepts and students' everyday experiences. However, problem posing, that is, the reformatting of existing problems and the generation of new ones, has been promoted by the…

In the modern information age, the quantity and complexity of spatiotemporal data is increasing both rapidly and continuously. Sensor systems with multiple feeds that gather multidimensional spatiotemporal data will result in information clusters and overload, as well as a high cognitive load for users of these systems. To meet future…

This study examined the factors that have an effect on student scores on the Florida End-of-Course (EOC) Assessment in four secondary Algebra 1 classrooms using interactive whiteboard tools (IWTs). Four teachers and 335 students were observed in one public suburban school in central Florida during the second half of the spring term. Hierarchical…

The purchase of 21st-century technologies for each middle school teacher in my school system coinciding with a historic lack of significant professional development in technology integration provided the impetus for the study. To address the problem, professional development focused on helping teachers use student response systems and mobile…

A quasi-experimental research study was conducted to investigate the performance of English learners (ELs) on mathematics assessments when using interactive whiteboard (IWB)-based instruction as compared to text-based instruction. A sample of 47 seventh-and eighth-grade EL students from ABC Middle School (name has been changed) was included in…
