There are diverse ways to construct instructional activities that teachers can use to foster their students' development of mathematical thinking. It is argued that the use of computational tools offers teachers the possibility of designing and exploring mathematical tasks from distinct perspectives that might lead their students to the…

Making sure law enforcement officers are current with their professional training has always been a top priority of police departments whether they must protect a city or a college campus. However, as training has expanded with many new certification categories, tracking all of these for each officer has grown more complex. This has prompted many…

This study evaluated a PowerPoint home safety (PPHS) presentation in enhancing awareness, knowledge and behavior change among senior center attendees in southern Illinois. Twelve centers were utilized as data collection sites in a pretest-posttest control group design. Through stratified randomization, centers were placed into categories (high,…

This article presents a randomized experiment evaluating a computer-assisted tutoring program. The software program, Alphie's Alley, provides reading tutors with assessment and planning tools and performance support. It provides students with animated presentations and engaging activities. In a yearlong study involving 25 schools using the Success…

Managing the design and production of online courses is challenging. Insufficient instructional design and inefficient management often lead to issues such as poor course quality and course delivery delays. In an effort to facilitate, streamline, and improve the overall design and production of online courses, this article discusses how we…

This study focuses on student development with Calibrated Peer Review (CPR)[TM], a web-based tool created to promote writing and critical thinking skills. Research questions focus on whether or not students showed improvement in writing and reviewing competency with repeated use of CPR in a senior-level biology course and whether the difference…

The convenient format, delivery, and accessibility of information offered by podcasting has made it a hot new trend. One of its limitations in educational applications, however, is its implementation primarily as a push technology--one that simply feeds users information. Podcasts tend to focus listeners inward and rarely encourage human…

Today's college students, the Net generation, have woven technology into their everyday repertoire of communication and connection tools. They use the Internet, e-mail, instant messaging, blogs, and social networking Web sites like Facebook and MySpace at higher rates than individuals from any other generation. Student affairs professionals,…

Does speed provide a "model for" rate of change in other contexts? Does JavaMathWorlds (JMW), animated simulation software, assist in the development of the "model for" rate of change? This project investigates the transference of understandings of rate gained in a motion context to a non-motion context. Students were 27 14-15 year old students at…

Intermolecular forces play an important role in many aspects of chemistry ranging from inorganic to biological chemistry. These forces dictate molecular conformation, species aggregation (including self-assembly), trends in solubility and boiling points, adsorption characteristics, viscosity, phase changes, surface tension, capillary action, vapor…

This study analyzes and describes the links between the curriculum policies of one urban school district in the US and an intervention by the economics firm Standard & Poor's (S&P). It characterizes the languages and values introduced to the district leadership by S&P as ideologically neoliberal. This school-level case study that makes…

Multiuser virtual environments (MUVEs) are quickly gaining importance as tools for foreign language instruction by promoting collaboration and social presence in a lifelike 3-D environment. One of the largest and fastest growing of these MUVEs is Linden Lab's "Second Life" (SL). With an international membership of over 9,000,000 residents, SL is…

A key challenge of effective teaching is assessing and monitoring the extent to which students have assimilated the material they were taught. Concept mapping is a methodology designed to model what students have learned. In effect, it seeks to produce graphical representations (called concept maps) of the concepts that are important to a given…

This article examines three important facets of the incorporation of new technologies into educational practice, focusing on emergent usages of the mathematical tools of computer algebra and dynamic geometry. First, it illustrates the interpretative flexibility of these tools, highlighting important differences in ways of conceptualizing and…

Research on teachers' (personal) theories and beliefs and their (practical) knowledge derived from experience, whether held implicitly or stated explicitly as their personal practical theories (PPTs), indicates that such beliefs can influence teachers' classroom practices and, therefore, the opportunities that their students have for learning.…
