A test of mental arithmetic skills was developed and normed for children in grades one to six. Statistical techniques were used to predict the probability correct for each item and to rank order the items. Students in a given grade took only one level of the test and inferences were made of their performance on those tests which they did not take.…

College Level Examination Program (CLEP) Tests were normed on a national basis, administering the test to nationwide samples of subjects. Norms appear in the booklet, CLEP Scores: Interpretation and Use, and consist of the test score means for groups of students receiving grades of A, B, C, D, and F in the relevant course, the proportion of…

Referring to several examples, the author argues that more time should be spent developing statistical concepts such as randomness and independence before developing mathematical models for statistical computations. (SD)

Analyzing the effects of tilting a probability board can be an effective method of introducing a discussion of models in a probability class. (SD)

Describes the electronic circuitry which can be used to demonstrate the buildups of Poisson distributions with very high precision. Analysis of the data obtained is included in the paper. (CP)

Activities involving rolling dice and recording results in diverse ways introduce children to a variety of basic mathematical concepts. Several games and activities are described. (SD)

The purpose of this paper is to present problems (and solutions) from the areas of marketing, population planning, system reliability, and mathematics to show how a computer simulation can be used as a problem-solving strategy in probability. Examples using BASIC and two methods of generating random numbers are given. (Author/MP)

This monthly column contains teaching suggestions on: using codes to convey information, flow proofs in geometry, and volleyball and probability. (MP)

An alternative approach to the widespread dissemination of birth control information and devices among adolescents, involves group or individual counseling for those females who are most susceptible to unplanned pregnancies. An inferential strategy is presented for identifying, according to defined groups, unmarried adolescents who appear…

Three activities involving children with the probability concepts of random selections and sample size are provided. (JT)

The existence of internationally increasing interest in early probability theory training is presented along with the conclusion that Australia is behind other countries in this area. (MN)

Features and tools to outline and shape the long-term learning process for ratio are presented, with examples. Ratio-anticipating activity and creating visual models and schemes are stressed, with the basis for a theory of teaching and learning ratio presented. (MNS)

A discussion of the classic probability hat check problem. The paper shows how the hat check problem can be viewed as a problem about enumerating certain members of the symmetric group of permutations on n symbols, with an ensuing generalization. (PK)

Provides mathematical activities in reproducible formats appropriate for students in grades 7-12. The objective is to practice using area models in analyzing compound situations and calculating the expected value or long-term average. (PK)
