In 4 experiments, students received a lesson consisting of computer-based animation and narration or a lesson consisting of paper-based static diagrams and text. The lessons used the same words and graphics in the paper-based and computer-based versions to explain the process of lightning formation (Experiment 1), how a toilet tank works…

The authors' experiments with long-distance arts collaboration in a multiform environment began in July 2002. They consider a multiform environment to be an interactive environment where different audiences experience a shared event from different and mutually exclusive frames of reference. The Dynamic Media Project team members had extensive…

Practically since their availability, a succession of audiovisual recording devices (e.g., reel-to-reel, VCRs, PCs) has been used to capture language samples, and myriad playback and broadcast devices (e.g., phonographs, radios, televisions) have provided access to authentic speech samples. The espousal of audiolingual theory in the 1950s brought…

Current theories of learning emphasize the importance of learner-centered, active, authentic, environments for meaningful knowledge construction. From this perspective, computerized case-based learning systems afford practice fields for learners to build domain knowledge and problem-solving skills and to support contextualized transfer of…

Through numerical investigations, this paper studies examples of the forced Duffing type spring equation with [epsilon] negative. By performing trial-and-error numerical experiments, the existence is demonstrated of stability boundaries in the phase plane indicating initial conditions yielding bounded solutions. Subharmonic boundaries are…

The introduction of educational technology to school classes promises--through the students' active engagement with mathematical concepts--the creation of teaching and learning opportunities in mathematics. However, the way technological tools are used in the teaching practice as a means of human thought and action remains an unsettled matter as…

Most of the off-the-shelf mathematics programs used in middle schools across the United States have little or no rigorous evidence attesting to their effectiveness. The U.S. Department of Education analysis based on a review of studies undergirding 44 math programs used in grades 6-9, including some of the nation's most popular textbooks for those…

Graphic tips for using the Geometer's Sketchpad (GSP) are described. The methods to import an image into GSP, define a coordinate system, plot points and curve fit the function using a graphical calculator are demonstrated where the graphic features of GSP allow teachers to expand the use of the technology application beyond the classroom.

The benefits of integrating single crystal X-ray diffraction into the curricula of the disciplines of science such as chemistry, biology, biochemistry physics, and many more are addressed. The results showed that students were able to complete all report requirements with the aid of handouts and instructor inputs, and remote control of the…

"DaisyQuest" is a software bundle that offers computer-assisted instruction in phonological awareness, targeting children aged three to seven years (or preschool to second grade). The instructional activities, framed in a fairy tale involving a search for a friendly dragon named Daisy, teach children how to recognize words that rhyme;…

In this article we investigate the use of latent semantic analysis (LSA), critiquing systems, and knowledge building to support computer-based teaching of English composition. We have built and tested an English composition critiquing system that makes use of LSA to analyze student essays and compute feedback by comparing their essays with…

This study examines the effects of an online workbook and a paper workbook on L2 vocabulary acquisition. Participants consisted of 549 L2 learners of Spanish enrolled in a large language program at an American state university. The participants received 4 hours of classroom instruction per week and worked with an online or a paper workbook once a…

This essay examines three issues that emerge from the literature on computer-mediated instruction and from the experience of teaching online oral communication courses: (1) To what extent can online courses realize economies of scale to reduce cost and increase enrollment? (2) What productive potential does tracking and monitoring online…

Although the Web allows for flexible learning, research has found that online students tend to lack focus, willingness to participate, confidence, and discipline. This study thus attempts to promote Web-based self-regulated learning from the social cognitive perspective, which emphasizes the interactions among personal, behavioral, and…

This study investigated acquisition and transfer of the modeling ability of fifth graders in various domains. Teaching interventions concentrated on the topic of marine ecosystems either through a modeling-based approach or a worksheet-based approach. A quasi-experimental (pre-post comparison study) design was used. The control group (n = 17)…
