Five models which perform search tasks of the Data Base Access and Search Environment (DBASE) are presented and used for comparison with subject search performance--unconstrained (rule-based, decision theoretic) and constrained (optimal rule-based, rule-based, probabilistic rule-based). Previous experiments and the modeling approach are briefly…

Brief articles on a linguistic approach to learning mathematics vocabulary, designing cross-figure puzzles, an activity with probability, and a problem with an erroneous solution are included in this section. (MNS)

A lesson for a sixth grade class that came out of an article in a Sunday newspaper is described. The instruction centered around an experiment in probability that was seen to provide an opportunity to add to pupil intuitive understanding of some basic notions. The lesson was viewed as worthwhile. (Author/MP)

Three probability problems designed to challenge students are presented: Liars and Diamonds, Heads Wins, and Random Walks. Other statistic problems are suggested that could involve computer simulations. (MNS)

Until recently, norms of experimental reasoning have lacked systematic theoretical development. Thus, it has been easy for psychologists like Tversky and Kahneman to misclassify certain human reasoning processes as being Pascalian and invalid, rather than as being Baconian and valid. (CP)

Some activities designed around the Monte Carlo method of solving probability problems are described. The instructional applications of this method involve physical models or simple BASIC computer programs. (MP)

Several BASIC computer programs designed to illustrate concepts in probability are presented. The programs are geared for the Apple II computer, but most samples are adaptable to other systems. (MP)

Four learning activities designed to teach some basic concepts of probability through experiential learning are presented. Worksheets designed for duplication are included. Two of the ideas are geared towards grades 1 through 5; the others are designed for grades 4 through 8. (MP)

Macready and Dayton introduced two probabilistic models for mastery assessment based on an idealistic all-or-none conception of mastery. Alternatively, an application of latent trait theory to mastery testing is proposed (a three parameter logistic model) as a more plausible model for test theory. (Author/CTM)

Provides details of a course that introduces chemical engineering students to a variety of spreadsheet applications. The course is taken concurrently with stoichiometry and introduces statistical analysis, probability, reliability, and quality control. (DDR)

Presents a framework for assessing probabilistic thinking based on validated data obtained from eight third grade children who served as case studies. Major constructs were sample space, probability of an event, probability comparisons, and conditional probability. Levels of thinking appear to agree with the levels of cognitive functioning…

Describes how probability is treated in the National Council of Teachers of Mathematics' (NCTM) "Principles and Standards of School Mathematics". (YDS)

The Core-Plus Mathematics Project (CPMP) is a four-year program emphasizing mathematical modeling, featuring full use of graphing calculators, building on the theme of mathematics as sense-making, and involving investigations of real-life contexts that lead to reinventing important mathematics. (MKR)

Presents examples to illustrate how conditional probability statements can be used to introduce conditional probabilities, how early applications can be found in sports data, and how conditional probability can be related to data collection and presentation in two-way tables. (MKR)

Uses probability models in problem-solving activities based on an episode of the television show "Gunsmoke." (MKR)
