The interfacing of various spectrometers with analog output to a personal computer running Microsoft Excel in the Windows environment is described. This low cost data acquisition solution is a useful replacement of a chart recorder for various UV-visible and infrared scanning spectrophotometers.

The inability of computer users who are visually impaired to access graphical user interfaces (GUIs) has led researchers to propose approaches for adapting GUIs to auditory interfaces, with the goal of providing access for visually impaired people. This article outlines the issues involved in nonvisual access to graphical user interfaces, reviews…

A simple Vernier software and Technology LabPro unit was used to interface a computer with a Durrum model 110 stopped-flow apparatus using the iron (III)--thiocyanate reaction. The software can readily be used to retrieve that data from the stopped-flow apparatus using one probe to measure the voltage and a second probe to trigger the data…

Quality of e-learning systems is one of the important topics that the researchers are investigating in the last years. This paper refines the concept of quality of e-learning systems and proposes a new framework, called TICS (Technology, Interaction, Content, Services), which focuses on the most important aspects to be considered when designing or…

The Oklahoma Association of Teacher Educators 2009 Journal includes the following four peer reviewed articles: (1) The Changing Role of Grandparents (Fred D. Hammond, III, Terry E. Spigner, Charolette Myles-Nixon, and Pauline Holloway); (2) Pedagogical Agent Instructional Design Challenges (Jon Martens); (3) Differences in Relatedness across…

Conversational technologies such as email, chat rooms, and blogs have made the transition from novel communication technologies to powerful tools for learning. Currently virtual worlds are undergoing the same transition. We argue that the next wave of innovation is at the level of the computer interface, and that mixed-reality environments offer…

Computer-based communication has tremendous potential to support older adults. But if people are to use such systems autonomously, it is necessary to move beyond current interfaces and systems and develop devices that fit into the environment of the user. Using a Grounded Theory approach, three focus groups were held and, subsequently, 9 older…

This paper compares several interface evaluation methods applied in the case of a computer based learning (CBL) environment, during a longitudinal study performed in three European countries, Greece, Germany, and Holland, and within the framework of an EC funded Leonardo da Vinci program. The paper firstly considers the particularities of the CBL…

The World Wide Web has changed the way people interact. It has also become an important equalizer of information access for many social sectors. However, for many people, including some sign language users, Web accessing can be difficult. For some, it not only presents another barrier to overcome but has left them without cultural equality. The…

Modern computing systems exploit graphical user interfaces for interaction with users; as a result, introductory computer science courses must begin to teach the principles underlying such interfaces. This paper presents an approach to graphical user interface (GUI) implementation that is simple enough for beginning students to understand, yet…

Open source online learning environments have emerged and developed over the past 10 years. In this paper we will analyze the underlying philosophy and features of MOODLE based on the theoretical framework developed by Hannafin and Land (2000). Psychological, pedagogical, technological, cultural, and pragmatic foundations comprise the framework…

This paper discusses findings and data analysis issues that resulted from a case usability test. The case usability test was conducted as part of a redesign project that aimed to update the existing home page of Indiana University Bloomington. The home page contained links to the Web sites that various institutions in the university had already…

This paper describes the impact that technological change over the past few decades has had on a number of key interfaces to the library catalog, including the user, resource, abstract/index, and union catalog interfaces. Areas of focus for future development are then highlighted, including: (1) reassessing data requirements and conventions in…

Grid computing allows large groups of computers (either in a lab, or remote and connected only by the Internet) to extend extra processing power to each individual computer to work on components of a complex request. Grid middleware, recognizing priorities set by systems administrators, allows the grid to identify and use this power without…

Discusses database interfaces and explains that collaboration is an important aspect of searching online information retrieval systems that requires explicit computerized support. Collaboration in physical and in digital libraries is discussed and an example of a system that supports collaboration between browsers, ARIADNE, is described. (105…
