Idle, Marion – Mathematics in School, 1979
The importance of place value is discussed. Examples illustrating place value in addition and subtraction are given. (MK)
Descriptors: Addition, Algorithms, Elementary Education, Elementary School Mathematics
Jamski, William D. – MATYC Journal, 1979
This study of seventh graders investigated the use of the calculator in learning conversion algorithms among fractions, decimals, and percents. The calculator was successful with some topics but not with others. (MP)

McKillip, William D.; Aviv, Cherie Adler – Arithmetic Teacher, 1979
An approach is suggested to the use of sets of practice exercises that is more like the actual use of computation by adults and may be more effective in attaining accuracy and speed. (MP)

Zelnio, Robert N.; And Others – American Journal of Pharmaceutical Education, 1977
The development of a simple computer algorithm designed for use by the individual educator or researcher in maintaining and searching reprint files is reported. Called BIBLIO, the system is inexpensive and easy to operate and maintain without sacrificing flexibility and utility. (LBH)

Savoy, Jacques – Information Processing & Management, 1997
Discussion of evaluation methodology in information retrieval focuses on the average precision over a set of fixed recall values in an effort to evaluate the retrieval effectiveness of a search algorithm. Highlights include a review of traditional evaluation methodology with examples; and a statistical inference methodology called bootstrap.…

Langenbucher, James W.; And Others – Journal of Consulting and Clinical Psychology, 1996
Six alternately weighted algorithms for diagnosing alcohol dependency in accordance with the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) based on statistical, unit, rational and random criterion weighting systems, were used to predict an array of concurrent validators and six-month drinking outcomes in a regional clinical…

Johnson, Andrew; Fotouhi, Farshad – Information Systems, 1996
Discussion of hypermedia systems focuses on a comparison of two types of adaptive algorithm (genetic algorithm and neural network) in clustering hypermedia documents. These clusters allow the user to index into the nodes to find needed information more quickly, since clustering is "personalized" based on the user's paths rather than…

Baeza-Yates, Ricardo; And Others – Information Systems, 1996
Discusses indexes for text databases and presents an efficient implementation of an index for text searching called PAT array, or suffix array, where the database is stored on secondary storage devices such as magnetic or optical disks. Additional hierarchical index structures and searching algorithms are proposed that improve searching time, and…

Armstrong, R. D.; And Others – Applied Psychological Measurement, 1996
When the network-flow algorithm (NFA) and the average growth approximation algorithm (AGAA) were used for automated test assembly with American College Test and Armed Services Vocational Aptitude Battery item banks, results indicate that reasonable error in item parameters is not harmful for test assembly using NFA or AGAA. (SLD)

Chen, Hsinchun; Chau, Michael – Annual Review of Information Science and Technology (ARIST), 2004
Presents an overview of machine learning research and reviews methods used for evaluating machine learning systems. Ways that machine-learning algorithms were used in traditional information retrieval systems in the "pre-Web" era are described, and the field of Web mining and how machine learning has been used in different Web mining…

Krieger, Carla R. – Journal of Chemical Education, 1997
Describes the use of Moe's Mall, a locational device designed to be used by learners, as a simple algorithm for solving mole-based exercises efficiently and accurately using dimensional analysis. (DDR)
Descriptors: Algorithms, Chemistry, Cognitive Structures, Educational Practices
Garfield, Eugene; Pudovkin, A. I.; Istomin, V. S. – Proceedings of the ASIST Annual Meeting, 2002
Discussion of mapping and visualizing in scholarly literature focuses on the development of software called HistCite for generating chronological maps of collections, where all cited references for source documents are captured, using scientific literature as an example. Generates tables of the most-cited works to help searchers identify the most…

Vazquez-Abad, Jesus; LaFleur, Marc – Computers and Education, 1990
Reviews criticisms of the use of drill and practice programs in educational computing and describes potentials for its use in instruction. Topics discussed include guidelines for developing computer-based drill and practice; scripted training courseware; item format design; item bank design; and a performance-responsive algorithm for item…

Jones, Leslie P.; And Others – Journal of the American Society for Information Science, 1990
Describes two computer programs--INDEX and INDEXD--that use statistical information about repeated phrases in documents to automatically index documents at the conceptual level. Sample output of the programs is provided, and plans to combine this method with linguistic and artificial intelligence techniques to provide a general conceptual…

Bell, D. A.; And Others – Journal of the American Society for Information Science, 1990
Investigates the value of applying principles derived from simulated annealing to clustering tuples in database design, and compares this technique with a graph-collapsing clustering method. It is concluded that, while the new method does give superior results, the expense involved in algorithm run time is prohibitive. (24 references) (CLB)
