The purpose of this study is to analyze the relationship between the grade performance of 128 students in an introductory micro-economics course and the average number of hours per week these students report spending on the Internet. The literature review offers a "priori" arguments supporting both positive and negative relationships.…

For more than one hundred years teachers have paddled beside the great ocean of mathematical adventure. Between them they have taught millions of young people. A few have dived in and kept swimming, some have lingered on the shore playing in pools, but most have dipped their toes in and run like heck in the other direction never to return. There…

What can Mali, an impoverished, land-locked West African nation, teach educators about mobile technology? Little to nothing, one might think. Yet in Mali, as in much of sub-Saharan Africa, teachers and students are increasingly using mobile technologies for learning and teaching. While educators in the United States have debated whether, why, and…

Collaborative inquiry learning is one of the most challenging and exciting ventures for today's schools. It aims at bringing a new and promising culture of teaching and learning into the classroom where students in groups engage in self-regulated learning activities supported by the teacher. It is expected that this way of learning fosters…

Experiments with an electric motor provide good opportunity to demonstrate some basic laws of electricity and magnetism. The aim of the experiments with a low-power dc motor is to show how the motor approaches its steady rotation and how its torque, mechanical power and efficiency depend on the rotation velocity. The tight relationship between the…

Blogs, short for Weblogs, began to show up in the late 1990s, based on online discussion boards centered on threaded topics. Currently, a blog typically refers to a Web site in which an individual posts entries and then allows for commentary from the readers. If scholars look to some educational theory, both novice and experienced bloggers can use…

Although there is strong evidence that massively multiplayer online games (MMOGs) constitute environments of social interactions and effective learning, we currently lack the tools for investigating the effectiveness of the social networks emerging as well as the cognitive aspects and knowledge acquisition such environments involve. Within this…

Students appear to be able to see number relationships and patterns but have difficulty recognizing the visual properties of shapes, especially if the shapes are in different positions. Their difficulty in the visual and spatial realm is often linked to a lack of drawing experience and possibly undeveloped fine-motor skills. The author, as a…

This study provides a national picture of the time American 6- to 12-year-olds spent playing video games, using the computer, and watching TV at home in 1997 and 2003, and the association of early use with their achievement and behavior as adolescents. Girls benefited from computer use more than boys, and Black children benefited more than White…

The use of e-portfolio systems in higher education has not grown as anticipated by early adopters when the potential benefits first became apparent, yet the promise remains. The vision of a flexible tool that meets multiple goals--serving as a showcase for student work, promoting self-reflection, supporting assessment and accreditation efforts,…

We present results of a literature review pilot study (326 papers) regarding the use of Computer Algebra Systems (CAS) in tertiary mathematics education. Several themes that have emerged from the review are discussed: diverse uses of CAS, benefits to student learning, issues of integration and mathematics learning, common and innovative usage of…

When we use technology to teach mathematics, we hope to focus on the mathematics, restricting the computer software systems to providing support for our pedagogy. It is a matter of common experience, however, that students can become distracted or frustrated by the quirks of the particular software system being used. Here, experience using the…

The methods that we teach students for computing with units of measurement are often not consistent with the practice of professionals. For professionals, the vast majority of computations with quantities of measure are performed within programs on electronic computers, for which an accounting for the units occurs only once, in the design of the…

Today's parents and their children use electronic gadgets and gizmos at such a prodigious rate that they are changing the way people live. Cell phones are ubiquitous. Kids constantly text, email, instant message, and send photos from their phones as well as their computers. The Internet, without a doubt, has a tremendous impact on modern family…

Geographically related queries form nearly one-fifth of all queries submitted to the Excite search engine and the most frequently occurring terms are names of places. This paper focuses on digital libraries and extends the basic services of existing library management systems to include new ones that are dedicated to geographic information…
