Discussion of educational software focuses on a model of educational software that was derived from a case study of two elementary school teachers participating in a software design process. Considers human-computer interface, interaction, software browsing strategies, and implications for teacher training. (Author/LRW)

Describes an experimental system designed to organize and provide access to Web documents using a faceted pre-coordinate indexing system based on the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan.

Many varieties of data acquisition systems are now available for science classrooms. Most systems consist of a range of sensors--typically called probeware--connected to an interface unit usually described as a datalogger due to its capacity to record data from these sensors. Although some systems operate independently, most units connect to a…

Probeware is increasingly being implemented in science classrooms because it is less expensive than it used to be and improvements in hardware and software have made it more accessible to students and teachers. Many probes or sensors can now simply be connected to a computer, calculator, or other handheld device, and will immediately begin to…

The Nielsen/Net report Ratings 2000, reported that in 2002, online usage at work jumped 17 percent year-over-year, driven by female office workers. Nearly 46 million American office workers logged onto the Web, the highest peak since January 2000. It was also predicted that the number of students using the Internet was expected to reach 13.5…

This article proposes three guidelines for mobile technology design that address the needs and goals of teachers who are considered mainstream with regard to technology use. Devices should be easy to learn and use, focused on the curriculum, and instruction-friendly. Only if the three guidelines are followed by hardware and software developers…

Computer interfaced electrostatic charge sensors allow both qualitative and quantitative measurements of electrostatic charge but are quite sensitive to charges accumulating on modern synthetic materials. They need to be used with care so that students can correctly interpret their measurements. This paper describes the operation of the sensors,…

This paper reports on an ongoing work in designing and developing a personalised search tool for teachers' online searching using Google search engine (repository) for the implementation and testing of the first research prototype.

As new users from the non-technical community are attracted to multimedia (MM) computing, it becomes necessary to design a convenient and easy-to-understand logical structure that facilitates data transfer from the MM data repository to MM applications. A recently introduced layered formalism, which describes MM applications in terms of the data…

This paper describes the design of a synchronous World Wide Web-based distance education environment developed at the Telematics Laboratory of Computer Engineer and Informatics Department (CEID) and Computer Technology Institute (Greece); the environment uses telematics services to conduct lessons over computer networks, simulating a traditional…

This paper describes technical and educational issues related to the development of SIMMPATICO, a multimedia tool for the teaching of Portuguese as a foreign language. The first section presents an overview of the motivation for the project. Package organization is discussed in the second section, including the linguistic approach and its…

This paper reports on a study aiming to develop a metadata model for e-learning coordination based on semantic web languages. A survey of e-learning modes are done initially in order to identify content such as phases, activities, data schema, rules and relations, etc. relevant for a coordination model. In this respect, the study looks into the…

Demonstrates a method of measuring the acceleration due to gravity. Provides an illustration of the apparatus and the data analysis. Suggests four different variations of this experiment. (YP)

Electronics Engineering Technology majors in the Industrial and Engineering Technology department at Central Michigan University have developed many real-world projects that represent the type of problem-solving projects encouraged by industry. Two projects that can be used by other educators as freestanding projects or as the core for further…

Digital library systems focus principally on the reader: the consumer of the material that constitutes the library. In contrast, this paper describes an interface that makes it easy for people to build their own library collections. Collections may be built and served locally from the user's own Web server, or (given appropriate permissions)…
