The development of a simple computer algorithm designed for use by the individual educator or researcher in maintaining and searching reprint files is reported. Called BIBLIO, the system is inexpensive and easy to operate and maintain without sacrificing flexibility and utility. (LBH)

Demonstrates that the number of kilometers of highway in the U.S. tends to grow exponentially and discusses what can be done to modify this growth. (MLH)

Describes an interactive computer-assisted linear least-squares curve-fitting program that allows students to generate basic tables, plots, and fits to their data. (MLH)

Presents a summary of the studies done by the Edinburgh Centre for Mathematical Education (ECME) on the use of practical activities in secondary schools. Argues that teachers may remain doubtful about the benefits of practical activities until they try them for themselves. (ASK)

Considers the random sum SN+X1+X2+...+XN with a stopping rule N=min((n: SN absorbing Markov chain. (AIM)

Reports on the performance and strategies of children working in one of three gender pairs (girls, boys, or boy/girl) on Geo-Logo tasks. The case studies presented reveal that the children showed a high level of engagement and learning in the Geo-Logo environment. Activities include the Turtle Paths curriculum unit, Missing Measures, and 200…

Discusses reasons why practical work is used only sporadically in lower secondary school math classes. Presents results of a comparative study between Greece and Scotland, focusing on culture as a differentiating factor of students' performance. (AIM)

Presents two problems posed to kindergarten children to challenge and to encourage discourse among the students working in small groups of 8 to 10 children. Results showed various levels of understanding and demonstrated various approaches which serve to give the teacher insight into the level of understanding of the class and the possible need to…

Suggests guided discovery techniques to help students find the rule by which an arrival sequence of consecutively numbered school buses is considered a "success," and presents arguments by Honsberger for a formula to calculate the number of successful patterns for a given number of buses. (SEW)

Describes a technique that uses a helium neon laser, a steel rule, a wooden rule, and a piece of paper to measure the diameter of a hair using the diffraction of light. Details on technique, mathematics, and sources of error are provided. (DDR)

Presents an activity illustrating the role that technology can play in modeling real-world problem situations and making connections across the curriculum. Includes using a graphical model to answer the questions. Lists related programs for TI-82 and TI-92 graphing calculators. (ASK)

Reviews M.B. DeBevoise's "Conversations on Mind, Matter, and Mathematics," (a book of translated conversations between Jean-Pierre Changeux and Alain Connes), which explores the question of whether a machine could reproduce the activity of the human brain. Explains how mathematics might be able to mediate between mind and matter. (DDR)

Presents activity pages containing world population data for students to use to predict future population figures and Consumer Price Index (CPI) data to track changes in the costs of the goods. Includes answer key. (KHR)

Explains an application of mathematical modeling within a school setting as well as progressive use of graphing calculators in mathematical modeling. Analyzes students' performances in the process of problem-solving using the problem of baton-passing in relay races. Discusses students' use of their mathematical knowledge and ideas when they used…

Focuses on vocabulary as one aspect of language that is necessary for overall mathematics achievement. Identifies potential vocabulary problems and provides instructional strategies to promote vocabulary development. (KHR)
