Kidder, F. Richard – Arithmetic Teacher, 1980
The author promotes an earlier introduction of decimals than is currently standard practice in most elementary mathematics programs. Suggested activities and related skills are reviewed. (MP)
Descriptors: Algorithms, Decimal Fractions, Elementary Education, Elementary School Mathematics

Mason, Diana S.; Shell, Duane F.; Crawley, Frank E. – Journal of Research in Science Teaching, 1997
Identifies and describes the differences in the problem-solving methods used by faculty teaching introductory chemistry and students enrolled in an introductory chemistry course. Results indicate that students correctly solve algorithmic-mode problems more frequently. Contains 33 references. (DDR)
Descriptors: Algorithms, Chemistry, Concept Formation, Higher Education

Mareschal, Denis; Shultz, Thomas R. – Cognitive Development, 1996
Presents a computational framework for modeling cognitive development that provides a language paradigm with which to compare and contrast different facets of children's knowledge. Describes the generative connectionist algorithm "cascade-correlation," the successful use of the algorithm to model cognitive development in various…
Descriptors: Algorithms, Children, Cognitive Development, Cognitive Measurement

Vanden Bosch, Peter – Mathematics Teacher, 1997
Presents a scenario in which two people solve a programming problem by discussing various number sequences and functions. The problem is redefined as one related to number theory and operations research. (DDR)
Descriptors: Algorithms, Computer Uses in Education, Educational Strategies, Functions (Mathematics)

Cruthirds, John; Dodd, Fred – Mathematics and Computer Education, 1997
Provides pathological examples for which graphing calculators sometimes give surprising, misleading, or incorrect results. Investigates some of the more interesting of these examples encountered while using the TI-85 in a variety of undergraduate courses including calculus and matrix theory. (DDR)
Descriptors: Algorithms, Calculators, Calculus, College Curriculum

Newton, Tyre A. – American Mathematical Monthly, 1990
Presented is a method where a quadratic equation is solved and from its roots the eigenvalues and corresponding eigenvectors are determined immediately. Included are the proposition, the procedure, and comments. (KR)
Descriptors: Algebra, Algorithms, College Mathematics, Equations (Mathematics)

Graham, Ron; Yao, Frances – American Mathematical Monthly, 1990
Described is computational geometry which used concepts and results from classical geometry, topology, combinatorics, as well as standard algorithmic techniques such as sorting and searching, graph manipulations, and linear programing. Also included are special techniques and paradigms. (KR)
Descriptors: Algorithms, College Mathematics, Geometric Concepts, Geometry

Boero, Paolo; And Others – For the Learning of Mathematics, 1989
Investigates children's behaviors and conceptual achievements in the transition from informal calculation strategies to a written division algorithm. Describes five different strategies observed in the solution of division problems. Discusses the implications of the children's behavior. (YP)
Descriptors: Algorithms, Computation, Division, Elementary Education

Nicholls, R. L.; Teter, W. D. – Engineering Design Graphics Journal, 1988
Described is a computer algorithm for obtaining the coordinates of vertices, chord factors, and dihedral angles for plotting orthographic and axonometric projections, and for tabulating chord lengths and dihedral angles. (Author)
Descriptors: Algorithms, College Science, Computer Graphics, Computer Software

Kim, Seock-Ho; And Others – Applied Psychological Measurement, 1994
Type I error rates of F. M. Lord's chi square test for differential item functioning were investigated using Monte Carlo simulations with marginal maximum likelihood estimation and marginal Bayesian estimation algorithms. Lord's chi square did not provide useful Type I error control for the three-parameter logistic model at these sample sizes.…

Arcavi, Abraham; Bruckheimer, Maxim – College Mathematics Journal, 1991
Presents the algorithm to approximate square roots as reproduced from the 1579 edition of an algebra book by Rafael Bombelli. The sequence of activities illustrates that the process of understanding an original source of mathematics, first at the algorithmic level and then with respect to its mathematical validity in modern terms, can be an…

Lazinger, Susan S. – Information Technology and Libraries, 1994
Describes the history and development of the algorithm that was used to produce a union list of monographs for ALEPH (Automated Library Expandable Program Hebrew University), Israel's research library network. The literature on merging online records is reviewed, case studies are examined, and problems with matching and merging online…
Descriptors: Academic Libraries, Algorithms, Bibliographic Records, Case Studies

Albert, James H. – Journal of Educational Statistics, 1992
Estimating item parameters from a two-parameter normal ogive model is considered using Gibbs sampling to simulate draws from the joint posterior distribution of ability and item parameters. The method gives marginal posterior density estimates for any parameter of interest, as illustrated using data from a 33-item mathematics placement…
Descriptors: Algorithms, Bayesian Statistics, Equations (Mathematics), Estimation (Mathematics)

Rada, Roy; And Others – Computers and Education, 1993
Discussion of collaborative learning focuses on the MUCH (Many Using and Creating Hypermedia) System, developed at the University of Liverpool (England) for designing and implementing collaborative learning systems. Examples of applications of the MUCH System for nursing education and for computer science education are described, including the use…

Hiebert, James; Wearne, Diana – American Educational Research Journal, 1993
Classrooms that used different instructional approaches to mathematics were observed, contrasting instruction that aimed to promote conceptual understanding rather than algorithmic skill with more conventional instruction. Results with 6 second-grade classrooms (135 students) suggest that relationships between teaching and learning are a function…
