Currently the challenges in e-Learning are converging the learning content from various sources and managing them within e-learning practices. Data mining learning algorithms can be used and the contents can be converged based on the Metadata of the objects. Ensemble methods use multiple learning algorithms and it can be used to converge the…

The growth in the availability of longitudinal data--data collected over time on the same individuals--as part of program evaluations has opened up exciting possibilities for evaluators to ask more nuanced questions about how individuals' outcomes change over time. However, in order to leverage longitudinal data to glean these important insights,…

The interpretation of single-case data requires systematic visual analysis across and within conditions. Graphs are a vital component for analyzing and communicating single-case design data and a necessary tool for applied researchers and practitioners. Several articles have been published with task analyses for graphing data with the new versions…

Learning environments aim to deliver efficacious instruction, but rarely take into consideration the motivational factors involved in the learning process. However, motivational aspects like engagement play an important role in effective learning-engaged learners gain more. E-Learning systems could be improved by tracking students' disengagement…

This article presents key steps in the design and analysis of a computer based problem-solving assessment featuring interactive tasks. The purpose of the assessment is to support targeted instruction for students by diagnosing strengths and weaknesses at different stages of problem-solving. The first focus of this article is the task piloting…

Presents a detailed analysis of courseware design activities based upon the use of conceptual data models for content elaboration. Highlights include discussions of computerized training systems, authoring languages and authoring systems, and the distinction between processing and data. (Author/LRW)

The use of modern technology in education has reached a turning point. Equipment found in schools is increasing, and computer-assisted instruction has been shown to achieve positive results. Learning to use computer utilities and databases should be given high priority. (MD)

Describes a computer program designed to enable undergraduate students to apply computer skills for data acquisition and processing in experimental chemistry. An example is given that examines the absorption spectra of conjugated molecules such as carbocyanine dyes, and the free electron model is explained. (six references) (LRW)

Describes the use of the Apple Macintosh and MULTIPLAN spreadsheet to record and analyze test data. Provides step-by-step instructions on data entry, item difficulty and discrimination calculations, test reliability, score distribution, and graphing of distributions. (JM)

Demonstrates how a spreadsheet program can do calculations, freeing students to question, analyze data and learn science. Notes several popular spreadsheet programs. Gives an example using Lotus 1-2-3 spreadsheets for a sampling experiment in Biology. Shows other examples of spreadsheet use in laboratory activities. (CW)

Description of a validated computer assisted instruction (CAI) program (The Addition Tutorial) illustrates how four critical components for instruction--learning principles application to instructional design; sufficient database; adequate motivational system; and delivery system which provides teacher learning environment control--might be…

Describes eight applications of the use of computers in teaching chemistry. Includes discussions of audio frequency measurements of heat capacity ratios, quantum mechanics, ab initio calculations, problem solving using spreadsheets, simplex optimization, faradaic impedance diagrams, and the recording and tabulation of student laboratory data. (TW)

Explains human interactive analysis as an architecture for using computer interactive technologies in the analysis of complex work environments. A project at the Naval Training Systems Center that used video-audio data to develop a multimedia database is described; the analysis and management of data are discussed; and decision processes are…

Describes traditional evaluation methods educators use for proposed administrative computer systems. Points out the need for an emphasis on portability as an important evaluation criteria. Discusses future trends in hardware and software costs and their effect on providing computer services to educational institutions. (TW)

The article describes the production process and contents of a two-hour videotape illustrating microcomputer applications with severely physically disabled adults in a long-term residential hospital in British Columbia. Software, special adaptive technology, and a program to train physically disabled adults to work in the microcomputer industry…
