This article presents a hybrid methodological technique that fuses elements of experimental design with qualitative strategies to explore mediated communication. Called the "qualitative experiment," this strategy uses focus groups and in-depth interviews "within" randomized stimulus conditions typically associated with…

This study was designed to examine the effect of Swedish Knife Model on students' understanding of digestive system. A simple experimental design (pretest-treatment-posttest) was used in the study and internal comparison of the results of the one group was made. The sample consisted of 40 7th grade Turkish students whose ages range from 13 to 15.…

In spite of the growing popularity of virtual worlds for gaming, recreation, and education, few studies have explored the efficacy of 3D immersive virtual worlds in post-secondary instruction; even fewer discuss the ability of virtual worlds to help young adults develop creative thinking. This study investigated the effect of virtual world…

As part of our investigations into the development of representational competence, we report results from a study in which we elicited sixteen graduate students' expressed mental models of commonly-used terms for describing organic reactions--functional group, nucleophile/electrophile, acid/base--and for diagrams of transformations and their…

We investigate the role of external inscriptions, particularly those of a spatial or visual nature, in the solution of probability word problems. We define a taxonomy of external visual representations used in probability problem solving that includes "pictures," "spatial reorganization of the given information," "outcome listings," "contingency…

Rutz presents samples of artist Steve Mumford's paintings from the Iraq war zone alongside photos or other war images and asks readers to examine notions of journalism, photojournalism, and the practices of representing war.

The sampling (probability) distribution for the sum of dice is presented graphically as a compelling demonstration of the Central Limit Theorem.

An emphasis on visual rhetoric can be incorporated into a variety of classrooms. This article illustrates teaching visual rhetoric to first-year composition students via interpretation and analysis through a trip to a local art museum for the first essay assignment and through an exploration of photography for the second essay assignment. In the…

Delving into the life and legacy of Henry VIII is both complex and captivating. People seem compelled to learn more abut his critical contributions and controversial conduct that range from the significant to the scandalous. Reflecting on the history of the world would be incomplete without investigating the events and escapades associated with…

Phylogenetic trees, such as the "Tree of Life," are commonly found in biology textbooks and are often used in teaching. Because students often struggle to understand these diagrams, I developed a simple, inexpensive classroom model. Made of pipe cleaners, it is easily manipulated to rotate branches, compare topologies, map complete lineages,…

Visual formative assessments (VFAs) allow more free more time for direct instruction. VFA's guide students in using simple images to demonstrate the essential learnings within a unit to themselves and the teacher. VFAs are powerful because they engage students to coalesce their understanding into a concise visual image. (Contains 2 figures.)

Recent studies exploring the effects of instructional animations on learning compared to static graphics have yielded mixed results. Few studies have explored their effectiveness in portraying procedural-motor information. Opportunities exist within an applied (manufacturing) context for instructional animations to be used to facilitate build…

Instead of the traditional set of slides, the visual aids of a presentation can now be graphic organisers (concept maps, knowledge maps, mind maps) on an infinite canvas. Constructing graphic organisers has a beneficial impact on learning, but this topic has not been studied in the context of giving a presentation. The present study examined this…

The changes of learning environments and the advancement of learning theories have increasingly demanded for feedback that can describe learning progress trajectories. Effective assessment should be able to evaluate how learners acquire knowledge and develop problem solving skills. Additionally, it should identify what issues these learners have…

Until now, studies have not looked at the importance of managing and reducing academic transition times in inclusion classrooms. In the present study, researchers examine the impact of teacher-approved, environmental modifications in the context of an inclusion class. The methodology used was a single-subject, multiple baseline design across four…
