Students' perceptions of engineering have been documented through studies involving interviews, surveys, and word associations that take a direct approach to asking students about various aspects of their understanding of engineering. Research on perceptions of engineering rarely focuses on how students would portray engineering to others.…

Interactive display systems give users flexibility to tailor their visual displays to different tasks and situations. However, in order for such flexibility to be beneficial, users need to understand how to tailor displays to different tasks (to possess "metarepresentational competence"). Recent research suggests that people may desire…

Visual literacy, the ability to interpret and create external representations (ERs), is essential to success in biochemistry. Studies have been conducted that describe students' abilities to use and interpret specific types of ERs. However, a framework for describing ERs derived through a naturalistic inquiry of biochemistry classrooms has not…

Imagine high school students glued to computer screens--not playing video games but applying their mathematical knowledge of functions to the design of three-dimensional sculptures. Imagine these students engaging in rich discourse as they transform functions of their choosing to design unique creations. Now, imagine these students using…

We present a new approach for the organization of schools, which we call the flexible scheduling paradigm (FSP). FSP improves student learning by dynamically redeploying teachers and other pedagogical resources to provide students with customized learning conditions over shorter time periods called "mini-terms" instead of semesters or years. By…

The goal of this action research is to increase student awareness of context clues, with an emphasis on student use of visual cues in making predictions. Visual cues in the classroom were used to differentiate according to the needs of student demographics (Herrera, Perez, & Escamilla, 2010). The purpose of this intervention was to improve…

This monograph offers an overview of the current research work carried out in Croatia and the surrounding countries, and specifically an interesting insight in teaching and learning issues in these countries. The authors discuss the need of the general population for becoming good problem-solvers in society of today, which is characterised by…

This article analyses educational modelling with the IMS-LD specification from the perspective of knowledge-based learning environments. An extension of the MOT visual language covers a wider variety of rule formats to provide control of the flow of activities in a multi-actor process-based scenario. The visual scenarios are executed by an…

The research investigated whether a Latent Semantic Analysis (LSA)-based approach to image retrieval can map pixel intensity into a smaller concept space with good accuracy and reasonable computational cost. From a large set of M computed tomography (CT) images, a retrieval query found all images for a particular patient based on semantic…

One can tell quite a lot about what goes on in a classroom or a school even if one visits after everyone has gone home. Just by looking at the walls--or, more precisely, what's on the walls--it's possible to get a feel for the educational priorities, the attitudes about children, even the assumptions about human nature of the people in charge. In…

The role of mental representations in mathematics and computer science (for teaching or research) is often downplayed or even completely ignored. Using an ongoing work on the subject, we argue for a more systematic study and use of mental representations, to get an intuition of mathematical concepts, and also to understand and build proofs. We…

The circular flow of income diagram is a simplified representation of the functioning of a free-market economic system. It illustrates how businesses interact with the other economic participants within the key macroeconomic markets that coordinate the flow of income through the national economy. Therefore, it can provide students of business with…

Motor overflow refers to involuntary movement or muscle activity coinciding with voluntary movement. We examined whether 16 young adults (18-30 years) and 16 older adults (50-80 years) could voluntarily inhibit overflow. Participants performed a finger pressing task, exerting 50% of their maximal force. Overflow was concurrently recorded in the…

The anatomy of the pelvis is complex, multilayered, and its three-dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three-dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using…

In this article, the author describes a lesson inspired by the book, "Who Will Tuck Me in Tonight?" by Carol Roth. The author used this lesson to teach her primary students how to use a ruler to make straight lines and how to use lines and shapes to draw animals. She also used the lesson to teach them about crayon resist. (Contains 1 online…
