The article outlines a series of mathematical tasks for gifted students (aged 7-12 years), stressing the value of research and inservice education that is firmly teacher and classroom based. (Author/DB)

The focus is on how line graphs can be used to approximate solutions to rate problems and to suggest equations that offer exact algebraic solutions to the problem. Four problems requiring progressively greater graphing sophistication are presented plus four exercises. (MNS)

The goals and history of the Mathematical Olympiads for Elementary Schools are described. Teams, levels, and gender are discussed, as well as teacher training, administration, scoring, and awards. Sample problems are included. (MNS)

Presents questions and answers about various chemical topics such as the supply of fossil fuels, mercury contamination of water, and lead and nitrous oxides emissions from gasoline. (MLH)

This book helps teachers define good questions, offers tips on how to create their own good questions, and includes a wide variety of questions for use in the classroom. Each chapter of the book is organized by subject area and age group so that teachers can locate the topic their class is working on, then select probing, thought-provoking…

Describes an alternative method to algebraic procedures for solving problems involving the proportional composition of a mixture. (TS)

Results are reported from a study of the problem-solving abilities of Swedish children aged 12-13. Illustrative problems and conclusions are given to describe a method for defining and testing problem solving. (MNS)

Using a microcomputer to test high school mathematics students for areas of weakness can save teachers' time, eliminate paperwork, and make testing enjoyable for the students. Results are immediately accessible and in several forms. (Author/TG)

Considered are the main elements of computational chemistry problems and how these elements can be used to formulate the problems mathematically. Techniques that are useful in devising an appropriate solution are also considered. (Author/TG)

Two instructional strategies incorporating a microprocessor-based computer system are described. These are the use of the system to drive a television monitor, and the system's use in generating problem sets. (MP)

Presents questions and answers concerning chemical aspects of air pollutants and the metabolism of drugs and poisons. (MLH)

Presents a problem involving fractions for discussing and sharing of student responses to the problem at a later date. (KHR)

Possible ways of mechanization for counting using a binary system are discussed. Shows a binary representation of the numbers and geometric models having eight triples of lamps. Provides three problem sets. (YP)

The current study investigated the discreet task completion hypothesis presented by C. H. Skinner (2002) by investigating how the rate of interspersing affects performance on and preferences for academic assignments. Specifically, 70 sixth-, seventh-, and eighth-grade students were presented with four assignment pairs of multiplication problems.…
