The effects of the Psychological Sense of Community in on-line and face-to-face academic courses
Recent studies have shown that the Psychological Sense of Community (PSoC) felt by students plays a key role in affecting their performance, satisfaction and persistence in academic degree programs. Hence, the lower student performance and higher dropout rates suffered by on-line courses in comparison with their face-to-face counterparts are often traced back to lower levels of PSoC caused by the lack of physical interactions among students who learn at a distance. The aim of this work is to und
An Interactive, Multimedia Environment for Exploring Tonal Pitch Space
Because they depict relations among musical pitches, chords, and key, charts in Fred Lerdahls Tonal Pitch Space can be rendered more accurately and vividly with multimedia authoring software. My renderings enable a user to orient charts toward any specific key, trace any of numerous possible paths, determine the depth of embedding of any element in any tonal context, and compute distances between elements. Lerdahls analyses can be depicted more vividly by synchronizing graphic images with th
Disciplinary/ Interdiciplinary Virtual Design Studio
The purpose of initiating Virtual Architectural Design Studio is the provision of a highly interactive studio environment independent of time and place by broadening the horizons of todays Turkish traditional architectural design studios through collaborations among universities thanks to European Credit Transfer System_ ECTS credit system. The method developed in virtual design studio (SMTS in Turkish/VDS in English) can be considered a sample for future virtual design studios and diciplinary
This Land Is Your Land, This Land Is My Land
In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least affect on the environment.
How Should Our Gardens Grow?
In this lesson, students will learn about types of land use by humans and evaluate the ways land is used in their local community. They will also consider the environmental effects of the different types of land use. Students will assume the role of community planning engineers and will create a future plan for their community. (Note: Teachers will need to check out the following book from the local or school library: Durell, Ann, Craighead George, Jean, and Paterson, Katherine. The Big Book For
In this lesson, students are introduced to the types of renewable energy resources. They are involved in activities to help them understand the transformation of energy (solar, water and wind) into electricity. Students explore the different roles of engineers working in renewable energy fields.
Identifying Coordination Agents for Collaborative Telelearning
This paper deals with identifying roles for coordination agents in a future collaborative telelearning environment. The current practice of students participating in a net-based simulation marketing game on-campus, is studied with an eye on designing a future collaborative telelearning environment where this same net-based simulation game will be central. The work described in this paper is situated within the theoretical foundations of computer supported collaborative learning (CSCL). In partic
Enhancing a Web-Based Distance-Learning Curriculum with Dedicated Tools
The work presented in this paper aims at supporting students involved in a Web-based distance-learning curriculum. For such a purpose, the Saafir system proposes students with different tools that support them in their appropriation of this curriculum, e.g. visualization of the curriculum from different points of view or construction of individual projects by putting different items of the curriculum into relation. In order to allow using Saafir with already existing distance-learning Websites,
An approach to distance learning curriculum appropriation
The work presented aims at supporting distance learning students in their appropriation of a curriculum. We propose an approach that consists in helping students to construct individual projects. We dissociate different aspects (planning, evaluation and regulation) that can be useful for this purpose, propose a technological approach (epiphyte system, ontology-based model) and example of tools currently provided by the Saafir framework.
Internet Scout Project
The US Geological Survey Volcano Hazards Program website presents its objectives "to advance the scientific understanding of volcanic processes and to lessen the harmful impacts of volcanic activity." The public can explore information on volcano monitoring, warning schemes, and emergency planning. Students and educators can find out about the types, effects, location, and history of volcano hazards. The website offers recent online volcano reports and maps, volcano factsheets, videos, and a pho
Exploratory Test of an Automated Knowledge Elicitation and Organization Tool
his paper combines the contents of two papers that were presented at the ITS 98 conference one focusing on knowledge representation (Shute, 1998) and the other describing a knowledge elicitation tool (Shute, Torreano, & Willis, 1998). There are three main purposes of this paper. First, as a means to stress instructional and assessment implications of different knowledge types, we will briefly overview knowledge representations. Second, we describe a novel cognitive tool designed to aid in knowle

Flexibility in macro-scripts for computer-supported collaborative learning
In the field of computer-supported collaborative learning (CSCL), scripts are designed to support collaboration among distant learners or co-present learners whose interactions are (at least partially) mediated by a computer. The rationale of scripts is to structure collaborative learning processes in order to trigger group interactions that may be rare in free collaboration. Fixing the degree of coercion is a delicate design choice: too rigid scripts would spoil the richness of collaborative in
Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie

An important concern facing electronics designers is heat dissipation. Especially in laptop computers and server farms, overheating can be a major problem. ElectronicsCooling is a free, quarterly publication that provides "practical information to the reader that relates to cooling of today's electronics." Every article since the magazine's debut in 1995 can be viewed from this site. Common topics are packaging, thermal design, and technical data related to many types of electronics. Contributio

This site examines the mouth and its various purposes, different types of teeth and their functions, bacteria that live in the mouth, and the processes of tooth decay and oral disease. The site includes activities and a teachers guide, which are designed for use by elementary school teachers.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,Throughout the video the student holds on to an idea that continents drifted apart because they were pushed by ocean currents. This video provides an example of how the interviewer conforonted the student with her drawing to have her think whether her personal theory made sense. He asked her how ocean currents could cause drift if there was no ocean, as seen on her diagram of the large land mass. When she tries t
Internet Scout Project
This remarkable Web site contains descriptions and animations of nineteen different kinds of engines. Engine types include internal combustion, steam, and sterling engines, and each page shows how the piston, crankshaft, and other components move together to generate power. The animations demonstrate the processes of intake, compression, and exhaust. Some of the featured engines have more detailed descriptions than others, and oftentimes, a brief account of the engine's history is included. One
