Discussed are the use of probability simulations in a mathematics classroom. Computer simulations using regular dice and special dice are described. Sample programs used to generate 100 rolls of a pair of dice in BASIC and Logo languages are provided. (YP)

This paper studies whether equating results can be improved if the variable that accounts for all systematic differences between equating populations is identified and used as an anchor in anchor test design or as a variable on which to match equating samples. The sample invariant properties of four anchor test equating methods (Tucker and Levine…

Multiple comparison procedures for controlling familywise Type I error and the false discovery rate are described and compared, including the traditional Bonferroni correction, a sequential (step-up) Bonferroni procedure (Hochberg, 1988), and a sequential false discovery rate procedure proposed by Benjamini and Hochberg (1995). Motivation for…

R. C. Blair (1991) developed tables of critical values for the generalized "t" and generalized rank sum tests that do not suffer inflation of Type I error. This study evaluated the critical values generated by Blair for situations in which sample size varies more than a maximum of a factor of two. The accuracy of the values was explored…

Describes a game in which players role-play students, teachers, superintendents, school board members, or parents as they explore the complexities and alternatives of the accountability issue. (BD)

A report on the second stage of a project in which applied computer simulation to better understand the variables affecting student performance in an elementary classroom is assessed. (Author)

THIS IS A FACTUAL CASE STUDY OF SOCIAL CHANGE IN A LARGE SUBURBAN SCHOOL DISTRICT EXPERIENCING CONFLICT BETWEEN THE SCHOOL BOARD, THE ADMINISTRATIVE OFFICER OF THE SCHOOL SYSTEM, AND THE GENERAL PUBLIC DURING A PERIOD OF RAPID POPULATION GROWTH. THE STUDY TRACES THE HISTORY OF VARIOUS PROBLEMS ARISING FROM RAPID POPULATION GROWTH AND THE…

The relation of games to life in general is discussed, with the suggestion that games constitute an excursion or "time out" from goal-directed activities in life, in which an alternative set of rules are established for a delimited period. A game thus constitutes a short-term parallel to life in general. As such, it acts, for children, as a device…

Techniques for automatic recognition of isolated words are investigated, and a computer simulation of a word recognition system is effected. Considered in detail are data acquisition and digitizing, word detection, amplitude and time normalization, short-time spectral estimation including spectral windowing, spectral envelope approximation,…
