The present study examines the relationship between alternation behavior and performance, and in addition, the effects of reinforcement configuration and relevant dimension upon the use of alternation strategies in probability learning. Also investigated is the hypothesis that children's errors at terminal levels of performance in a two-choice…

Campbell (l969) argued for the interrupted time-series experiment as a useful methodology for testing intervention effects in the social sciences. The validity of the statistical hypothesis testing of time-series, is, however, dependent upon the proper identification of the underlying stochastic nature of the data. Several types of model…

This sixth unit in the SMSG junior high mathematics series is a student text covering the following topics: permutations and selections; probability; similar triangles and variation; non-metric geometry; volumes and surface areas; the sphere; and unsolved problems in mathematics. (DT)

Socio-political forecasting, a new dimension to university planning that can provide universities time to prepare for the impact of social and political changes, is examined. The four elements in the process are scenarios of the future, the probability/diffusion matrix, the profile of significant value-system changes, and integration and…

Examines a statistical model in which the users of an online system continually update their estimated probability of success, and quit or continue the search according to the expected utility of each action. The implications for search strategies are discussed. (Author/EM)

This essay illustrates a technique for reducing the risks of capital investment decisions involving considerable sums for advanced technologies by considering its application to a problem that arises frequently in selection of automated library systems. Incomplete information, using available information, selecting a system, and consultants are…

Describes probabilistic document retrieval systems as a sequential learning process, in which the system learns the parameters of probability distributions describing the frequencies of feature occurrences in relevant and nonrelevant documents. Several techniques for estimating the parameters of distributions are described and the results of tests…

This article considers various kinds of probability and non-probability samples in both experimental and survey studies. Throughout, how a sample is chosen is stressed. Size alone is not the determining consideration in sample selection. Good samples do not occur by accident; they are the result of a careful design. (Author/JAZ)

Evaluations of special education interventions are different from research on medical interventions. Educational evaluations would be more useful if they applied an actuarial, or probability approach. Information should be collected over time and using various measures, thus increasing the available data. (GDC)

Confirms that in cloze testing, it is unnecessary to use standard size spaces and reveals a high correlation between synonymic scoring and verbatim scoring. Indicates also that a specific probability concepts test is comprehensible and readable by the great majority of students for whom it was devised. (FL)

A coin tossing game and a dice rolling game are explained for use in teaching probability concepts. (DT)

A glyph--short for hieroglyphic--is a form of picture writing that conveys information. This book uses 10 glyphs to teach math concepts that are linked to the new NCTM Standards. There are four key parts to each glyph: (1) a legend (or survey questions); (2) directions for the teacher that tell students what to draw, color, or write based on…

This book offers ideas to enrich instruction and help teachers explore the intrinsic beauty of math. Through dozens of examples from arithmetic, algebra, geometry, and probability, the symmetries, patterns, processes, paradoxes, and surprises that have facilitated generations of great thinkers are revealed. Activities include: (1) The Beauty in…

The materials and ideas in this document are intended to be used by teachers in schools in order to bring adults and children together to experience good mathematics. It features an evening of hands-on mathematics scheduled for one night a week for four weeks. Students and adults come together to share mathematics activities, solve problems, and…
