This work presents a convenient framework for developing interactive chemical education software to facilitate the integration of macroscopic, microscopic, and symbolic dimensions of chemical concepts--specifically, via the development of software for gel permeation chromatography. The instructional role of the software was evaluated in a study…

Conventional lecture approaches view the process as a teacher-led method of imparting knowledge ("presentation" lecture), whereas modern theories suggest that the teaching methods employed should aim to inspire the student to learn rather than simply provide them with knowledge ("performance" lecture). The aim of the current…

This paper examines the educational impact of the implementation of the tutorial activity "Changes in Energy and Momentum" from "The Tutorials in Introductory Physics" in five different instructional settings. These settings include (1) a completely computer-based learning environment and (2) use of cooperative learning groups with varying levels…

The rapid development of computer graphics technology has made possible an easy integration of dynamic visualizations into computer-based learning environments. This study examines the relative effectiveness of dynamic visualizations, compared either to sequentially or simultaneously presented static visualizations. Moreover, the degree of realism…

Virtual worlds are an emerging technology in computer-assisted learning. Due to the novelty of these new learning spaces, little research has been done on the use or the effects on students learning foreign languages. This research looks at how the use of the virtual world Second Life affects the motivation of students in an undergraduate Spanish…

This paper explores a new approach to engage students in authoring educational content. This approach was implemented in AnnotEx (Example Annotator) system, which allows students to annotate computer programming examples with line-by-line explanations and review annotations produced by their peers. A controlled study of AnnotEx presented in this…

Peer collaboration is a pedagogical method currently used to facilitate learning in classrooms. Similarly, computer-learning environments (CLEs) are often used to promote student learning in science classrooms, in particular. However, students often have difficulty utilizing these environments effectively. Does peer collaboration help students…

Constructing a representation in which students express their domain understanding can help them improve their knowledge. Many different representational formats can be used to express one's domain understanding (e.g., concept maps, textual summaries, mathematical equations). The format can direct students' attention to specific aspects of the…

Grounded in a constructionist paradigm, this study examined elementary school teachers' learning while creating technology-rich instructional materials. Sixteen teachers at an elementary school were interviewed about their experience. Using the components of Technological Pedagogical and Content Knowledge as an analytical framework, inductive…

This paper introduces an approach to analyzing temporal patterns of knowledge construction (KC) in online discussions, including consequences of role assignments. The paper illustrates the power of this approach for illuminating collaborative processes using data from a semester-long series of discussions in which 21 university students were…

Virtual learning environments constitute current information systems' category for electronically supported training and development in (higher) education(al) and vocational training settings. Frequently expected advantages of using virtual learning environments refer, for instance, to the efficiency, individuality, ubiquity, timeliness and…

"WebGrader" is an online instrument developed to evaluate and assess oral competency in the basic course. It is the result of a 15-year study, using Morreale and Hackman's (1994) work as a general model, and "The Competent Speaker" speech rating criteria in particular (Morreale, Moore, Taylor, Surges-Tatum, & Hulbert-Johnson, 1990; Morreale,…

The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and…

This article reviews the literature of multimedia glosses in computer assisted language learning (CALL) and their effects on L2 vocabulary acquisition during the past seventeen years. Several studies have touched on this area to examine the potential of multimedia in a CALL environment in aiding L2 vocabulary acquisition. In this review, the…

For decades foreign and second language teachers have taken advantage of the technology development and ensuing possibilities to use e-learning facilities for language training. Since the 1980s, the use of computer assisted language learning (CALL), Internet, web 2.0, and various kinds of e-learning technology has been developed and researched…
