Describes the Belief Function Model for automatic indexing and ranking of documents which is based on a controlled vocabulary and on term frequencies in each document. Belief Function Theory is explained, and the Belief Function Model is compared to the Standard Vector Space Model. (17 references) (LRW)

Administration of the Conflict Tactics Scales to 1,997 mothers found that risk factors included the mother's age at time of birth of the abused child, size of family, and minority group status. However, there was not a significant relationship when mother's age was measured at time of abuse. (Author/JDD)

Describes a study to determine middle school children's representational strategies to form part-whole or part-part relationships for relational numbers such as proportions, ratios, or fractions. Quantitative and qualitative analysis revealed that children prefer a part-part representation to solve relational quantity problems. (15 references)…

Described is a strategy that allows students to experiment with probability without applying formulas to solve problems. Students are able to intuitively develop concepts of probability before formal definitions and properties. Sample problems are included along with BASIC programs for some of the problems. (KR)

The actuarial profession is described to provide secondary school mathematics teachers insights into how actuaries use mathematics in solving real life problems. Examples are provided involving compound interest, the probability of dying, and inflation with computer modeling. (MDH)

Presents research findings related to students' intuitive ideas about the concepts of chance to inform teachers how students form their concepts of probability and statistics. Discusses adolescents' conceptions of uncertainty, judgmental heuristics in making estimates of event likelihood, the conjunction fallacy, the outcome approach, attempts to…

Discusses a problem involving probability and uncertainty that students can investigate experimentally or theoretically and transforms the problem to a two-player game so that students can be introduced to some fundamental concepts of decision making. Includes computer programs used to analyze the problems. (MKR)

Inference is considered for the marginal distribution of "X" when ("X", "Y") has a truncated bivariate normal distribution. The "Y" variable is truncated, but only the "X" values are observed. A sample of 87 Otis test scores is shown to be well described by this model. (SLD)

Details the use of the game Yahtzee with modified rules to help students understand the extreme improbability of obtaining complex structures by chance in the process of evolution. Includes a discussion of probability calculations. (DDR)

Discusses information retrieval systems and the need to have them adapt to user needs, integrate information in any format, reveal patterns and trends in information, and answer questions. Topics include statistics and probability; natural language processing; intelligent agents; concept mapping; machine-aided indexing; text mining; filtering;…

Presents a game in which if player is playing a match of this game with an opponent, at each step in the game he has to decide whether to continue or to stop. Helps students to develop a strategy for making such a decision based on the expected gain and related probabilities. (Author/ASK)

Presents an activity on probability and area in which students try to decide which door to buy. (ASK)

Discusses the performance of Malaysian secondary school students on a probability concepts test covering various intuitive and taught probability concepts. Describes the establishment of a probability concepts hierarchy and considers probability understanding in relation to independent variables. Boys, Form Six students, and students with a higher…

An investigation of the use of probabilistic methodologies for identifying cheaters on classroom multiple-choice examinations concludes that imperfections in the detection techniques, coupled with legal issues, necessarily limit the applicability and utility of these strategies. (Author)

Presents an instrument designed as a profile of teacher achievement and teacher needs with regard to the probability and statistics strands in the mathematics curriculum. Discusses uses for the instrument and further development possibilities. (MM)
