The relationship between certain personality variables and the degree to which examines display certainty in their responses was investigated. (Author)

The focus of the present experiments was to examine the effect of adapting the context of a presentation to a student's background. The results showed familiarity of context to be an influential factor in learning quantitative material. (Author/PN)

"Capture" is a game that requires players to perform several computations on each turn and to choose an optimal move, thus promoting higher-order thinking and probability notions. Rules are given, playing is described, and extension activities are noted. (MNS)

The problem deals with calculating the probability that two or more students in a given class have the same birthday. A sample of an experiment that can be carried out by hand in a class is first noted. A program written in BASIC and a sample run is then presented. (MP)

Explored differences between factors related to occupational preference and occupational choice for college students. Results supported the model indicating occupational preference was primarily a function of pure attraction; occupational choice was a function of attraction, expectancy of attaining an occupation, and consideration of expected…

Details of an 18-lesson unit of instruction that has been used successfully with eighth-, ninth-, and tenth-grade classes are presented. Each lesson centers around individual computer programs written in Applesoft BASIC. Copies of two programs are provided, and ways to acquire the other 16 are noted. (MP)

A program designed to calculate pi using a Monte Carlo simulation based on "throwing darts" at a quarter circle of unit radius inscribed in a unit square is presented. (MP)

The history of probability from ancient times is presented. The relationship between the mathematical and experimental definitions of probability are detailed. (MP)

A recent recommendation by Holt (EJ 200 576) that coefficients resulting from estimating log-linear and similar models should not be interpreted is argued to be based on lack of clarity about the substantive and theoretical importance of the choice between dummy and effect coding for categorical variables. (Author/GDC)

Describes the use of relevance feedback to select additional search terms and discusses the extraction of these terms from a maximum spanning tree connecting all terms in the index term vocabulary; retrieval effectiveness for different spanning trees is shown to be similar. Eight references are included. (Author/BK)

The probability and statistics portion of an optional comprehensive mathematics sequence offered at the secondary level in New York public schools is presented. (MP)

Examines the relationship between probability learning and aging by studying the performance of 48 young and 48 old adults in a probability learning task which used different reinforcement procedures and material rewards. (CM)

A simple probability game was analyzed hierarchically in terms of the strategies that would lead most often to an efficient sequence of plays. A series of experiments showed there was no relationship between the use of first-order strategy and knowledge of the probability content of the game. (Author/GDC)

A sample lacking variance was judged less probable than a variable sample and a sample representing the upper half of the population was judged less likely than one representing both. As range and mean approached an ideal, samples appeared more probable. A hierarchical model of sample cues seems appropriate. (CPT)
