Today's economic situation demands that learning organizations become more diligent in their business dealings to reduce cost and increase bottom line for survival. While there are many champions and proponents claiming that game-based learning (GBL) is sure to improve learning, researchers have, thus far, been unable to (re)produce concrete,…

Scientifically literate citizens need to understand how scientists evaluate competing explanations. Likewise, students must learn to critically evaluate the quality of scientific knowledge and weigh alternative explanations. Regrettably, high school graduates often are not critically evaluative about scientific topics. To help remedy that, this…

This study investigated pre-service teachers' perception of and technology competency in creating and using e-picture books in their future classrooms. Participants were 114 pre-service teachers in a required Early Childhood Education undergraduate course at a mid-western university in the United States. As part of the course assignments,…

Using a single-subject reversal design, this study evaluated the use of a compare-contrast strategy on the ability of students with autism spectrum disorder to comprehend science text. Three middle school students with high-functioning autism and their teacher participated in this study. A content analysis comparing the number of meaning units in…

Background: The research on diagrammatic representations highlights their importance for the teaching and learning of mathematics. However, the empirical evidence to support their use in the classroom is mixed and somewhat lacking. Purpose: The aim of this study was to develop the use of diagrammatic representations of mathematical concepts in…

The DVD, a key component of the "Autism in the Schoolhouse" initiative, is designed to provide general education teachers with strategies for supporting their middle and high school students with autism. It was produced by the Organization for Autism Research (OAR) in collaboration with Fairfax County (VA) Public Schools, and made possible by…

"Solving the Unknown with Algebra" is a new math program aligned with the National Council of Teachers of Mathematics (NCTM) standards and designed to help students practice pre-algebra skills including using formulas, solving for unknowns, and manipulating equations. Developed by The Actuarial Foundation with Scholastic, this program provides…

This paper explores how students, as multimodal storytellers, can weave powerful narratives blending modes, genres, artefacts and literary conventions to represent the real and imagined in their lives. Part of a larger ethnographic case study of student writing in a middle years class for immigrant students learning English as an additional…

This dissertation explores fifth and eighth grade students' interpretations of three kinds of mathematical representations: number lines, the Cartesian plane, and graphs of linear functions. Two studies were conducted. In Study 1, I administered the paper-and-pencil Linear Representations Assessment (LRA) to examine students'…

Even as higher education institutions offer more distance education courses, the attrition rate in these courses remains higher than face-to-face courses. One of the most cited reason by students who drop out of distance education classes is the lack of social interaction. Educational technology researchers have studied this problem from a sense…

Visual texts, such as photographs, paintings, film, political cartoons, maps, charts, and graphs are important resources used for a variety of purposes in the history classroom. Aligning instructional use of visual texts to key developmental skills within the area of historical thinking should be a central concern to teachers of historical…

The purpose of the present study was to examine how the use of V-diagrams one of the learning techniques used in laboratory studies in experiments conducted regarding the 10th grade lesson unit of "waves" influenced students' achievements. In the study, a quasi-experimental design with a pretest and posttest control group was used. The…

The software industry needs well-trained software designers and one important aspect of software design is the ability to model software designs visually and understand what visual models represent. However, previous research indicates that software design is a difficult task to many students. This article reports empirical findings from a…

The study challenged the current practices in cognitive load measurement involving complex problem solving by manipulating the presence of pictures in multiple rule-based problem-solving situations and examining the cognitive load resulting from both off-line and online measures associated with complex problem solving. Forty-eight participants…

The International Science and Engineering Visualization Challenge, recently established by the National Science Foundation (NSF), is an alleged attempt at public outreach. The NSF encourages scientists to submit visualizations that would appeal to non-expert audiences by displaying their work in an annual "special feature" in "Science" magazine,…
