In this paper we designed a STEM outreach program with a modular tissue engineering education tool (we refer to as "modular cyclic-stretch device") to engage high school students in STEM hands-on activities. Using simple machines such as gears and rotating cams, students were able to build a custom device to apply cyclic stretch to…

Analogy is a powerful learning mechanism for children to learn novel, abstract concepts from only limited input, yet also requires cognitive supports. My dissertation sought to propose and examine number lines as a mathematical schema of the number system to facilitate both the development of rational number understanding and analogical reasoning.…

Amidst academic societies and agencies that accredit computing education there is a growing enthusiasm to reexamine the efficacy of the traditional model of curricular description that focused on areas of knowledge. The knowledge model informed the architecture and design of programs of teaching and learning in post-secondary, degree-granting…

The purpose of this study was to investigate the technological and pedagogical constructs underlying Turkish preservice teachers' behavioral intentions to use interactive whiteboard based on UTAUT model and TPACK using three structural equation models; technological framework, pedagogical framework, and integrated model. Within this scope,…

This article examines the term "whiteness," providing a historical review for context. It uncovers whiteness using educational theory that identifies three aspects of curriculum--explicit, implicit, and null. A particularly unexamined biblical interpretation itself illustrates the explicit curriculum. Visual images that permeate the…

One distinguishing feature in terms of national curriculum revisions is the emphasis on invention education in the subject of technology. This study investigates how South Korean middle school students perceive inventors. A manufactured tool for testing and a checklist for evaluating images of inventors were created to assess drawings of 115 8th…

Mother tongue education is accomplished with four basic language skills. These skills are listening, speaking, reading and writing skills. One of the basic skills that increase the vocabulary of the individual is the reading skill. Understanding and comprehension are important in this skill. Understanding of reading is a complicated process. There…

Introductory electricity is a difficult topic for most lower secondary students, especially the development of an adequate conceptualisation of voltage is seen as a major obstacle. A few instructional concepts concerning the teaching and learning of physics have been proven helpful when it comes to constructing conceptual knowledge. For example,…

Visual representations are prevalent in STEM instruction. To benefit from visuals, students need representational competencies that enable them to see meaningful information. Most research has focused on explicit conceptual representational competencies, but implicit perceptual competencies might also allow students to efficiently see meaningful…

Practices, positioned through a sociomaterial lens make visible everyday work, often challenging our understanding of practices in consequence. Artists, and the world of contemporary art offer interesting contexts to explore practices through a sociomaterial lens and render visible everyday work important in the accomplishment of art. As such,…

Increasing interconnectedness of people and goods enhances the complexity of geographical problems. For students to understand geography, systems thinking--and in this context, the use of causal diagrams--is a promising approach. A quasi-experimental design is used in which the systems thinking ability of students working with causal diagrams is…

A prelecture video can be made more engaging with a lightboard. With this method, an instructor presents material in a video while directly facing the camera and writing on a transparent screen in front of them. We present instructions for constructing an inexpensive removable desktop lightboard that can be stored as smaller pieces. We share tips…

Construction of visual material to enhance audience understanding of an oral presentation is an important skill in educational and professional settings. Many first-year undergraduates may not be familiar with the basic principles of effective slide design to increase audience understanding. However, faculty face time pressures to train students…

A major goal of education is to help students retain as much meaningful information as possible for long periods of time. The learning process by which students acquire new knowledge and behaviors is closely related to memory, which is the core of cognition. In a previous study, we developed virtual reality visualization model (VRVM) that can be…

All mathematics is comprised of three elements: symbols, nominalizations, and images, and the combination of these three elements determine the mathematical meaning. However, adolescents may not be aware of these three elements. When asked to describe mathematical language, they will often name equations and images, two of the three elements. Over…
