The use of counting for subtraction was investigated. Counting for subtraction is related to counting-on for addition and to four skills: the ability to use the subtrahend cardinality to gain entry into the count sequence, the ability to use the minuend cardinality to gain entry into the count sequence, the ability to use the count sequence to…

These modules view aspects of computer use in the problem-solving process, and introduce techniques and ideas that are applicable to other modes of problem solving. The first unit looks at algorithms, flowchart language, and problem-solving steps that apply this knowledge. The second unit describes ways in which computer iteration may be used…

A study of 130 undergraduate students enrolled in a course on auiovisual techniques sought to determine whether heuristic or algorithmic computer-based problem solving training would be differentially effective for students varying in cognitive complexity as measured by the Educational Set Scale (ESS). The interaction was investigated between one…

THE INVESTIGATION IS CONCERNED WITH THE DEVELOPMENT OF AUTOMATIC INDEXING, ABSTRACTING, AND EXTRACTING SYSTEMS. BASIC INVESTIGATIONS IN ENGLISH MORPHOLOGY, PHONETICS, AND SYNTAX ARE PURSUED AS NECESSARY MEANS TO THIS END. IN THE FIRST SECTION THE THEORY AND DESIGN OF THE "SENTENCE DICTIONARY" EXPERIMENT IN AUTOMATIC EXTRACTION IS OUTLINED. SOME OF…

The 31 papers in this collection represent approximately 35 percent of the manuscripts which were submitted for consideration to the Research and Theory Division of the Association for Educational Communications and Technology (AECT) for presentation at the 1980 AECT convention. All papers were subjected to a blind reviewing process and the ones…

About 25 children in each of grades 3, 5, 7, 9, and 11 were tested in their ability to solve linear syllogisms, such as: John is taller than Mary. Mary is taller than Pete. Who is tallest--John, Mary, or Pete? Response latencies and error rates decreased across grade levels and sessions. Component latencies also generally decreased with increasing…

CYBERNETICS, OR "THE ART OF ENSURING THE EFFICIENCY OF ACTIONS," MUST BE A TOOL SUPPORTING PEDAGOGY, THE EDUCATIONAL PHENOMENON, THAT IS DETERMINED BY COMMUNIST PARTY POLICY. ALTHOUGH ANALOGIES BETWEEN MEN AND MACHINES DERIVE FROM THE CONCEPTS OF A SYSTEM (A CONFIGURATION OF STABLE ELEMENTS), INFORMATION (A PROBABILITY SCIENCE),…

This pamphlet contains five reports on different aspects of the Oakleaf Small Computer Project. The major objective of the project was to individualize elementary mathematics instruction by using a fully-integrated system of computer-assisted instruction, evaluation, and class management. The curriculum used was based on IPI Mathematics. The…

This report describes the algorithm and materials developed at the Research Institute of Logopedics and Phoniatrics (University of Tokyo) for use in testing the abilities of Japanese students in the pronunciation and hearing of English monosyllabic words. The report begins with a description of the method employed for selecting the words to be…

Three specific contributions to the field of information retrieval are presented. The first two describe the establishment of an adaptive, interactive man-machine dialogue that produces a form of unsolicited librarian-like assistance for the user in his selection of index terms to characterize an indexing function. The data set upon which the…

The ESY Analysis Aids are a collection of materials and procedures related to and organized for use in making decisions concerning year-round school program alternatives. They are restricted largely to procedures dealing with the budgetary impact of school calendar manipulation, but can be used as a guide in monitoring progress in an ESY…

The contention is made that group performance data are useful in the construction and interpretation of criterion-referenced tests. The Mastery Learning Test Model, which was developed for analyzing criterion-referenced test data, is described. An estimate of the proportion of students in an instructional group having achieved the referent…

Describes origami, the oriental art of paper folding as an activity to teach upper elementary students concepts and skills in geometry involving polygons, angles, measurement, symmetry, and congruence. (PK)

Summarizes a simple design algorithm which identifies nested loops of equations which must be solved by trial-and-error methods. The algorithm is designed to minimize such loops, provides guidance to the selection of variables, and delineates the order in which systems of equations are to be solved. Examples are included. (TW)

Investigates techniques for automatic classification of book material focusing on: computer-based surrogation of monographic material, book surrogate clustering on basis of content association, evaluation of resultant classifications. Test collection (250 books) is described with surrogation by means of back-of-the-book index, table of contents,…
