The present study has explored how pairs of students deployed digital tools (spelling software) as resources in spontaneously occurring corrections of spelling errors. Drawing on the sociocultural theory of learning and ethnomethodological (Conversation Analytic) insights into social interaction, it has identified a range of consistent practices…

The use of PowerPoint slides has become an almost ubiquitous practice in university classrooms, however little research has examined whether the timing of lecture slide availability to students (either before or after lecture) affects classroom behaviour or exam performance. Using a 2 (slide availability condition) x 2 (course type)…

This article describes a new approach to teaching bioinformatics using "Arabidopsis" genetic sequences. Several open-ended and inquiry-based laboratory exercises have been designed to help students grasp key concepts and gain practical skills in bioinformatics, using "Arabidopsis" leucine-rich repeat receptor-like kinase (LRR…

Purpose: This paper aims to investigate the organizational commitment of teachers in India and Iran. It is an attempt to understand how these perceptions vary by demographic variables such as age and subject taught by teachers. Design/methodology/approach: Data were collected from 721 high school teachers in Bangalore (India) and Sanandaj (Iran).…

As music making and technology grow more entwined, it is important for teachers to become familiar with available hardware, software, Web apps, yMIDI, sequencing, sampling and other emerging products. If music students in today's digital world wish to make a career out of doing what they love--whether as performers or conductors, composers or…

Few laboratory procedures describe the use of circular dichroism (CD) at the undergraduate level. To increase the number of laboratory exercises using CD, a thermal denaturation study of myoglobin using CD is described to assess protein stability. Values obtained from a more classic linear data analysis approach are consistent with data analyzed…

This article details the many benefits of educators' use of digital camera technology and provides an activity in which students practice taking portrait shots of classmates, manipulate the resulting images, and add language arts practice by interviewing their subjects to produce a photo-illustrated Word document. This activity gives…

Information systems strategy is an increasingly important component of overall business strategy in small and medium-sized enterprises (SMEs). The need for readily available and consistent management information, drawn from integrated systems based on sound and upgradeable technologies, has led many senior company managers to review the business…

In this article, I discuss research on the use of technology to support the writing of students with learning disabilities. Struggling writers can benefit from a wide range of computer applications for writing. Word processing, spelling checkers, word prediction, and speech recognition offer support for transcription and revision. Word processing…

This article describes the usefulness of Web analytics for understanding the users of an academic library Web site. Using a case study, the analysis describes how Web analytics can answer questions about Web site user behavior, including when visitors come, the duration of the visit, how they get there, the technology they use, and the most…

The "Cognitive Tutor[R] Algebra I" curriculum, published by Carnegie Learning, is an approach that combines algebra textbooks with interactive software. The software is developed around an artificial intelligence model that identifies strengths and weaknesses in each individual student's mastery of mathematical concepts. It then…

Enterprise resource planning software does what school leaders have always wanted their computer systems to do: It sees all. By integrating every IT application an organization has--from purchasing and inventory control to payroll--ERPs create a single unified system. Not only does this give IT managers a holistic view to what is happening in the…

Growth curve modeling has become a mainstay in the study of development. In this article we review some of the flexibility provided by this technique for describing and testing hypotheses about: (1) intraindividual change across multiple occasions of measurement, and (2) interindividual differences in intraindividual change. Through empirical…

In this article, the author describes his experiments with Steiner's Porism using the drawing/animation program "Cinderella" and discusses insights into this theorem gleaned from the manipulation of his animation. (Contains 2 notes.)

Mathematical string sculptures constitute an extremely beautiful realm of mathematical crafts. This snapshot begins with a description of a marvelous (and no longer manufactured) toy called Space Spider, which provided a framework with which children could experiment with string sculptures. Using a computer-controlled laser cutter to create frames…
