The recent popularity of benchtop (BT) NMR systems has prompted its applications in undergraduate laboratories around the world. Owing to their low maintenance cost, due to the lack of a superconducting magnetic core, and simple operation, these BT NMR systems can fulfill many of the learning objectives outlined in the undergraduate organic…

Students experience many difficulties learning the fundamental relationships in Newtonian mechanics, partly due to preexisting mental models that originate from their everyday lives. These preconceptions often persist even after instruction in mechanics and lead to a supposed incompatibility between physics lessons in school and personal…

A new procedure for performing quantitative measurements in teaching optics is presented. Application of the procedure to accurately measure the rate of change of the variable refractive index of a water-denatured alcohol mixture is described. The procedure can also be usefully exploited for measuring the constant refractive index of distilled…

In an effective e-learning game, the learner's enjoyment acts as a catalyst to encourage his/her learning initiative. Therefore, the availability of a scale that effectively measures the enjoyment offered by e-learning games assist the game designer to understanding the strength and flaw of the game efficiently from the learner's points of view.…

Inexpensive video analysis technology now enables students to make precise measurements of an object's position at incremental times during its motion. Such capability now allows users to "examine", rather than simply "assume", energy conservation in a variety of situations commonly discussed in introductory physics courses. This article describes…

This paper presents an exploratory study about the development of a structural and measurement model for the technological acceptance (TAM) of a web-based educational tool. The aim consists of measuring not only the use of this tool, but also the external variables with a significant influence in its use for planning future improvements. The tool,…

The level of learners' expertise has been used as a metric and diagnostic mechanism of instruction. This metric influences mental effort directly according to the applications of cognitive load theory. Cognitive efficiency, an optimal measurement technique of expertise, was developed by Kalyuga and Sweller to replace instructional efficiency in…

Audit trail analysis can provide valuable insights to researchers and evaluators interested in comparing and contrasting designers' expectations of use and students' actual patterns of use of educational technology environments (ETEs). Sequence analysis techniques are particularly effective but have been neglected to some extent because of real…

Discusses software metrics and describes a study of graduate students in Hong Kong that evaluated the relevance of using software metrics as a means of assessing students' performance in programing. The use of four basic metrics to measure programing skill, complexity, programing style, and programing efficiency using Pascal is examined. (13…

This article presents a survey of computer-based tracking in CALL and the uses to which the analysis of tracking data can be put to address questions in CALL in particular and second language acquisition (SLA) in general. Adopting both quantitative and qualitative methods, researchers have found that students often use software in unexpected ways,…

By order of the Civil Service Commission of Belgium, Didascalia, the University of Antwerp developed an adaptive system for evaluating second-language proficiency. A computer model based on probability and information theory was developed; the first module of the ATLAS test currently assesses approximately 15,000 civil servants yearly. (one…

Describes the formative evaluation of a multimedia computer system that provides remedial support for university students learning concepts concerning the structure and function of the human brain and describes usability studies of the system using the Software Usability Measurement Inventory (SUMI). Analysis of SUMI items and the student…

Some specific computer-based tools for collecting and examining audit trails, i.e., data that describe a learner's path through a computer-based instruction (CBI) lesson, are detailed. Data analysis and measurement issues related to audit trails are also discussed. A particular set of embedded computer-based tools currently being used at San Diego…

Describes the development of a computer-based learning strategy to assist with the teaching of foreign language business correspondence in a variety of business courses. The article describes the result as a mixture of commercially available software supported by materials designed specifically for the students' needs. (four references) (Author/CK)

Discusses a conference centering around the added value of technologies in language learning. Topics include the necessity of networks, added value analysis for "a priori" specification and "a posteriori" assessment, funding, textbooks, user expectation, assessment methods, integration into other learning systems, and an action plan.
