A well-constructed just qualified candidate (JQC) description is needed to arrive at a reasonable passing score for licensure tests. Traditionally, such descriptions consist of a list of knowledge and skill statements without sufficient context to internalize its intended meaning, allowing the standard-setting panelists to make idiosyncratic…

The interpretation of medical images is a primary task for radiologists. Besides two-dimensional (2D) images, current imaging technologies allow for volumetric display of medical images. Whereas current radiology practice increasingly uses volumetric images, the majority of studies on medical image interpretation is conducted on 2D images. The…

We propose that there exists mathematical knowledge for teaching (MKT) specific to visual representations (VRs), abbreviated MKT-VR. We define a VR as a graphic creation, such as a diagram or drawing, which illustrates quantities and shows quantitative relationships or which illustrates geometric properties of figures and shows geometric…

Within the broad area of whole number operations, understanding and solving word problems continues to be an important area of inquiry. In the present study we draw on the framework of representational fluency to examine conceptual and procedural understandings that are exhibited by a group of Malaysian seven-year-olds as they attempted to solve…

Findings are presented from an analysis of how six future middle-grade teachers reasoned with strip diagrams and a variable parts perspective on proportional relationships to develop and explain equations in two variables. One equation was for two quantities varying together and one was for a line through the origin in a coordinate plane. Both…

The importance of plants is not as clearly understood as that of animals. This lack of attention is called "plant blindness" and is considered one of the most important problems in biology education. Textbooks do not put much emphasis on plants and, therefore, they may contribute to plant blindness. In this research, ten textbooks used…

This study was conducted to examine the effects of modality across gender on undergraduate student achievement when learning Algebra concepts. Cognitive Load Theory (CLT) and Cognitive Theory of Multimedia Learning (CTML) provided a framework for this study to describe in depth the concept of the modality principle. Participants were undergraduate…

This qualitative study explores how middle school students in the Western United States participated in a curricular unit that focused on action for socioenvironmental sustainability. Using inductive coding and building on prior research, I examined actions that students took during this sustainability unit and how students talked about action…

Using electronic tablets to present flash cards for teaching skills is becoming common among practitioners. However, no published study compared the effectiveness of the electronic tablet-based flash cards to paper flash cards for teaching receptive labeling skills. The purpose of this study was to compare the efficacy of the iPad-based and paper…

Background: Recent evidence suggests PechaKucha--a presentation style utilizing simplified visuals, narration, and rigid time constraints--may promote various learning outcomes and instructor goals better than traditional PowerPoint presentations. Objective: The purpose of this study was to test the effectiveness of students' PechaKucha compared…

The vast extent to which quantitative prerequisites vary among post-secondary geoscience programs often presents a challenge for educators and students alike in courses for which math and physics are foundational. This study discusses the design of GEOAppS, a suite of educational numerical models, and its application toward lowering the…

The likelihood of teaching a student with autism spectrum disorder (ASD) has steadily increased over the past two decades. However, the practical information about working with students with ASD has not increased at a similar rate. Teachers may therefore be unaware of simple modifications they can make to their classrooms to meet the needs of…

The purpose of the study was to compare the effectiveness and efficiency of animated and non-animated mobile social story maps using the mobile learning environment that the authors developed. An application using the story map method based on social stories was developed. Mobile social story map was presented with animated and non-animated…

Thesis defense presentation slides (TDPS) are a significant and unique genre in the final ritual of master's students' learning journey. However, few studies have explored this genre, especially its rhetorical structure, so students have scant knowledge of it. This study investigates the moves and steps of this genre focusing on their Introduction…

In the early nineteenth century, the ideas of reform pedagogues gave rise to a didactic turn towards the visual that criticised an exclusive textual mediation of knowledge through books and lectures. To raise educational effectualness, teachers came under increasing pressure to incorporate high-profile media technologies into their lessons. Yet,…
