The Models and Modeling Perspectives (MMP) has evolved out of research that began 26 years ago. MMP researchers use Model Eliciting Activities (MEAs) to elicit students' mental models. In this study MMP was used as the conceptual framework to investigate the nature of students' models of curve fitting in a problem-solving environment consisting of…

The purpose of this research was to investigate student conceptions of the topic of asymptotes of rational functions and to understand the connections that students developed between the closely related notions of asymptotes, continuity, and limits. The participants of the study were university students taking Calculus 2 and were mostly freshmen. …

In 2005, over 100,000 e-Learning courses were offered in over half of all U.S. postsecondary education institutions with nearly 90% of all community colleges and four year institutions offering online education. Streaming video is commonplace across the internet offering seamless video and sound anywhere connectivity is available effectively…

In the past two decades, research on learning has focused on understanding how students think and how that thinking becomes more sophisticated over time. Some researchers have verified sufficient consistency and robustness in their findings relating to these constructs, which they have articulated in the form of learning trajectories. While an…

This innovative resource describes how teachers can help students employ "literacy tools" across the curriculum to foster learning. The authors demonstrate how literacy tools such as narratives, question-asking, spoken-word poetry, drama, writing, digital communication, images, and video encourage critical inquiry in the 5-12 classroom. The book…

The limitations of home Internet connections make Personal Videoconferencing (PV) interaction vulnerable to network trouble. This dissertation explores how novice couples collaboratively manage PV network trouble so as to carry on their conversation. It is found that transmission/reception and their perturbations are material frames for…

The purpose of this study was to examine, using a modified visual cliff apparatus, possible perceptual differences at crawling age between infants born preterm and infants born at term without documented visual or motor impairments. Sixteen infants born at term and 16 born preterm were encouraged to crawl to their caregivers on a modified visual…

A large number of teachers and tutors of English as a Second Language (ESL) lack professional-level preparation. The Basic Training and Resources for Teaching English to Speakers of Other Languages (BTRTESOL) program is being developed to prepare untrained, novice, volunteer ESL teachers to be more successful. In contrast with previous programs…

The Young Adult Library Services Association (YALSA), a division of the American Library Association (ALA), announced its 2010 annual lists of Fabulous Films for Young Adults and Amazing Audiobooks for Young Adults ages 12 to 18. This article presents the list of titles that were released in January 2010 during the ALA Midwinter Meeting in Boston,…

We created a series of videos for an online introductory astronomy course at the Pennsylvania State University in part to address the lack of personal presence in online courses. Based on surveys administered to the students during the semester, we found that these videos were effective in creating an instructor presence within the online course.…

In this article, we trace learning across the digital video production process through case studies with four youth media arts organizations (YMAOs) across the United States. We hypothesize that what these organizations share is a series of key moments throughout the production process in which youth must articulate the relationship between the…

In this article, the author talks about telepresence, a combination of real-time video, audio, and interactive technologies that gives people in distributed locations a collaborative experience that's as close to being in the same room as current technology allows. In a culture that's still adjusting to iPhone-size screen displays and choppy cell…

ADHD in adulthood is a valid, prevalent, distressing, and interfering condition. Although medications help treat this disorder, there are often residual symptoms after medication treatment, and, for some patients, they are contraindicated. Compared to other disorders, such as mood and anxiety disorders, there are few resources available for…

Focusing on expanding technical capabilities and new collaborative possibilities, we address 4 challenges for scientists who collect and use video records to conduct research in and on complex learning environments: (a) Selection: How can researchers be systematic in deciding which elements of a complex environment or extensive video corpus to…

For some time now, questions have been asked about the impact of television and video materials on the cognitive and social development of preschoolers and older children. More recently, these same questions have been asked in relation to the extensive exposure to these media that infants and toddlers are currently experiencing. To answer these…
