Dewdney, A. K. – Scientific American, 1989
Discussed are three examples of computer graphics including biomorphs, Truchet tilings, and fractal popcorn. The graphics are shown and the basic algorithm using multiple iteration of a particular function or mathematical operation is described. An illustration of a snail shell created by computer graphics is presented. (YP)

Levine, Michael V.; Drasgow, Fritz – Psychometrika, 1988
Some examinees' test-taking behavior may be so idiosyncratic that their test scores are not comparable to those of more typical examinees. A new theoretical approach to appropriateness measurement is proposed that specifies a likelihood ratio test and an efficient computer algorithm for computing the test statistic. (TJH)

Steinberg, Heinz – For the Learning of Mathematics, 1989
The question is raised: What comes first: rules of calculation or the meaning of concepts? The pressures on the teacher to teach and simplify knowledge to algorithms are discussed. The relation between conceptual and procedural knowledge in school mathematics and consequences for the teacher's professional knowledge are considered. (DC)

Woodward, John – Focus on Learning Problems in Mathematics, 1995
Presents a historical review of technology-based computer program development and research in mathematics for special education. Discusses two themes: the consistent focus on mastering computational algorithms and the use of technology both as a teaching tool and as a means of guiding teacher behavior. Contains 81 references.

Savoy, Jacques – Information Processing and Management, 1994
Proposes a new learning algorithm to improve the retrieval effectiveness of the search system used in the hypertext environment using an extended Boolean model with links to improve the ranking of retrieved items. Highlights include the basic retrieval scheme, the learning scheme, and a review of basic probabilistic retrieval models. (Contains 32…

Clements, M. A.; Lean, G. A. – Mathematics Education Research Journal, 1994
Investigated the continuous fraction concepts of (n=59) students in grades four, five, and six. Students were confident and accurate when performing sharing tasks, but were much less successful on continuous quantity tasks involving formal fraction language and symbol manipulation fraction tasks. (14 references) (Author/MKR)

Towne, Douglas M.; And Others – Interactive Learning Environments, 1990
Explains the Intelligent Maintenance Training System that allows a nonprogramming subject matter expert to produce an interactive graphical model of a complex device for computer simulation. Previous simulation-based training systems are reviewed; simulation algorithms are described; and the student interface is discussed. (Contains 24…

Manatt, Richard P.; Price, Peter P. – Journal of Personnel Evaluation in Education, 1994
Implementation of a career ladder in the Cave Creek Unified School District (Arizona), with a five-factor teacher performance evaluation and accompanying placement algorithm successfully dispersed teachers across plan levels. After three years, there have been no teacher grievances filed, and teachers feel ownership and authority over the career…

Kouba, Vicky L.; Franklin, Kathy – Teaching Children Mathematics, 1995
Discusses mathematics education research on multiplication and division which implies that instruction should emphasize development of a sound conceptual basis for multiplication and division rather than memorization of tables and rules. Presents action research ideas. (10 references) (MKR)

Kamii, Constance; Warrington, Mary Ann – Hiroshima Journal of Mathematics Education, 1995
Describes an attempt to encourage fifth- and sixth-graders to invent their own ways of solving problems involving division with fractions. Emphasizes the importance of social interaction in Piaget's constructivism and explains why debate and verification are important for children's construction of logico-mathematical knowledge. (22 references)…

Frants, Valery I.; And Others – Journal of the American Society for Information Science, 1993
Discusses the design of multiversion information retrieval systems and provides a theoretical justification for the necessity of creating such systems to perform an optimal search for the user's information needs. Topics discussed include comparing query formulations; feedback algorithms; an experiment with a test collection; and the mechanism of…

Casey, Carl – Journal of Computer-Based Instruction, 1992
Discussion of transactions in computer-based instruction for ill-structured and visual domains focuses on two transactions developed for meteorology training that provide the capability to interact with video and graphic images at a very detailed level. Potential applications for the transactions are suggested, and early evaluation reports are…

Reise, Steven P.; Due, Allan M. – Applied Psychological Measurement, 1991
Previous person-fit research is extended through explication of an unexplored model for generating aberrant response patterns. The proposed model is then implemented to investigate the influence of test properties on the aberrancy detection power of a person-fit statistic. Difficulties of aberrancy detection are discussed.

Bockenholt, Ulf; Bockenholt, Ingo – Psychometrika, 1991
A reparameterization of a latent class model is presented to classify and scale nomial and ordered categorical choice data simultaneously. The model extension represents a nonhomogeneous population as a mixture of homogeneous subpopulations. Simulated data and data from a magazine preference survey of 347 college students illustrate the model.…

Kantor, Paul B. – Annual Review of Information Science and Technology (ARIST), 1994
Identifies current trends in the automation of indexing, of information retrieval, and of interaction between the system and the users. Topics discussed include location, navigation, and indexing; digital libraries; matching documents to queries; weight of concepts; query structure, including fuzzy sets; algorithms; stemming; clustering; users'…
