Teaching undergraduates the basic properties of an estimator can be difficult. Most definitions are easy enough to comprehend, but difficulties often lie in gaining a "good feel" for these properties and why one property might be more desired as compared to another property. Simulations which involve visualization of these properties can…

The purpose of this study is to reveal the opinions of the teacher candidates about mind mapping technique used in Geography education of undergraduate program. In this study, the qualitative research techniques were used. The study group consists of 55 teacher candidates. The teacher candidates have been asked for their opinions about the process…

This article describes how Paul Duncum teaches elements of realististic-style imagery. The elements he teaches are framing, angles of view, lighting, depth of field, and body language. He stresses how each of these elements contributes to meaning, and shows how they apply equally to old master paintings and today's digital photography.

Comparison learning is a promising approach for learning complex real-life visual tasks. When medical students study radiological appearances of diseases, comparison of images showing diseases with images showing no abnormalities could help them learn to discriminate relevant, disease-related information. Medical students studied 12 diseases on…

To create rich learning experiences, it is important to engage students from the very beginning of a course and lay the foundation for constructing a community of active learners. The activities described here using "organism cards" connect students' previous knowledge to course goals and address key themes in biology while initiating…

A molecular orbital (MO) diagram, especially its frontier orbitals, explains the bonding and reactivity for a chemical compound. It is therefore important for students to learn how to construct one. The traditional methods used to derive these diagrams rely on linear algebra techniques to combine ligand orbitals into symmetry-adapted linear…

This study investigated how enriching visualizations with arrows indicating the motion of objects may help in conveying dynamic information: Multiple static-simultaneous visualizations with motion-indicating arrows were compared with either multiple visualizations without arrows or a single visualization with arrows. Seventy-one students were…

The increasing visuality of our culture was observed in 1994 by Mitchell, who coined the term "pictorial turn" to describe the interest in the visual taking place in culture and discourse (Mitchell, 1994). Since then, this process has increased further, particularly in all the areas of digital/new media. This chapter will consider this…

A within-subject ABAB reversal design was utilized to investigate the effects of graphic feedback and goal setting on employee closing task completion. Goal setting was contingent upon baseline performance and graphic feedback was posted weekly. It was found that goal setting and graphic feedback improved employee closing task completion.…

Research has established that students often consider the delivery of instructor feedback to be a face-threatening event. To minimize the potential negative effects of feedback, verbal and nonverbal face-threat mitigation (FTM) strategies are utilized by instructors. Advances in digital feedback systems, like online documents and learning…

The topic of tangible drawings for individuals who are blind is an important one to the field of visual impairment. However, it has not been addressed so far in a literature review. In this article, the authors review the selected literature on tactile picture naming and provide a quantitative look at this literature by presenting results related…

Martin Gardner wrote about a coin-flipping trick, performed by a blindfolded magician. The paper analyses this trick, and compares it with a similar trick using three cups flipped in pairs. Several different methods of analysis are discussed, including a graphical analysis of the state space and a representation in terms of a matrix. These methods…

This paper reports on a study that introduces and applies the "K[subscript 5]Connected Cognition Diagram" as a lens to explore video data showing teachers' interactions related to the partitioning of regions by axes in a three-dimensional geometric space. The study considers "semiotic bundles" (Arzarello, 2006), introduces "semiotic connections,"…

We conducted two experiments to address questions over whether 9-month-old infants believe that objects depicted in realistic photographs can be picked up. In Experiment 1, we presented 9-month-old infants with realistic color photographs of objects, colored outlines of objects, abstract colored "blobs," and blank pages. Infants most commonly…

This article will demonstrate that practice-led photographic research offers an example of dialogical encounter. Through recourse to an outline of my own practice and the experience of completing a practice-led doctoral thesis, the article will account for photographic practice and interdisciplinary research in terms of dialogism. This will…
