A method for generating 3x3 magic squares is developed. A series of questions relating to these magic squares is posed. An invesitgation using matrix methods is suggested with some questions for consideration. (LS)

This bibliography lists books and articles discussing graphic aspects of human communication. References have been selected for their relevance to the design of self-instructional texts for the adult learner; for the most part, research on younger children, on non-text media, and on non-educational texts is not included. Items are organized into…

Developing learning-teaching procedures is only possible if one knows the internal processes to be formed. Two 'psycho-logical' models and activity algorithms for foreign language teaching are discussed. Construction of such operational models for grammatical action has a high diagnostic value for research and development in FL teaching. See FL…

The learning machine described in this paper acquires concepts representable as conjunctive forms of the predicate calculus and behaviors representable as productions (antecedent-consequent pairs of such conjunctive forms): these concepts and behavior rules are inferred from sequentially presented pairs of examples by an algorithm that is probably…

The training requirements analysis model (TRAMOD) described in this report represents an important portion of the larger effort called the Digital Avionics Information System (DAIS) Life Cycle Cost (LCC) Study. TRAMOD is the second of three models that comprise an LCC impact modeling system for use in the early stages of system development. As…

The major advantage of sequential classification, a technique for automatically classifying documents into previously selected categories, is that the entire document need not be processed before it is classified. This method assumes the availability of a priori categories, a selection of keywords representative of these categories, and the a…

Three different methods of teaching fraction computation were compared using community college student scores on measures of fraction computation, fraction understanding, and attitude towards mathematics. One method used conventional algorithms; the second, a control for the effect of using a calculator, used conventional algorithms and…

Computer graphics systems typically produce a single, machine-like character font. At most, these systems enable the user to (1) alter the aspect ratio (height-to-width ratio) of the characters, (2) specify a transformation matrix to slant the characters, and (3) define a virtual pen table to change the lineweight of the plotted characters.…

PRELIMINARY DATA FROM FIVE LECTURES UTILIZING PROGRAMED TEXTS AND FEEDBACK TO VERIFY KNOWLEDGE OF THE SUBJECT, DEMONSTRATE THE SUPERIORITY OF PROGRAMED INSTRUCTION FOR VOLUME OF MATERIAL ASSIMILATED AND TEACHING ALGORITHMS. THIS ARTICLE WAS TRANSLATED FROM "VESTNIK VYSSHEV SHKOLY," MOSCOW, VOLUME 21, NUMBER 7, 1963, AND IS AVAILABLE FROM…

Two factor analysis algorithms, previously described by P. Horst, have been programed for use on the General Electric Time-Sharing Computer System. The first of these, Principal Components Analysis (PCA), uses the Basic Structure Successive Factor Method With Residual Matrices algorithm to obtain the principal component vectors of a correlation…

As part of an introductory computer programming course, students were assigned seven programs selected to expose them to the varied applications of BASIC. Three additional programs were selected by the students themselves from other courses or from topics in the text which had not been covered in class. The topic which seemed to arouse the…

This study, part of an instructional development project, explores the effects of three different representations of functional algorithms in an introductory chemistry laboratory. Intact classes were randomly assigned to a flowchart, list, or standard prose representation of the procedures (algorithms). At the completion of 11 laboratory sessions,…

Commonality analysis is an attempt to understand the relative predictive power of the regressor variables, both individually and in combination. The squared multiple correlation is broken up into elements assigned to each individual regressor and to each possible combination of regressors. The elements have the property that the appropriate sums…

This study investigated the effects of the nature of the algorithm, reinforcement, and level of problem difficulty on the ability of fourth graders to solve addition problems as measured by the number of problems correctly solved and the number of columns attempted. Subjects were selected for high scores on a test of basic addition facts; only…

Intended to be used in conjunction with a traditional curriculum, this book demonstrates the use of the computer, especially the on-line, interactive type of computer, to solve a variety of problems studied in secondary school mathematics. Each chapter presents several problems, and each problem introduces one or two concepts that must be…
