The use of computer-based automated assignment systems in economics has expanded significantly in recent years. The most widely used system is Aplia which was developed by Paul Romer in 2000. Aplia is a computer application designed to replace traditional paper-based assignments in economics. The main features of Aplia are: (1) interactive content…

Physics 30 is a 12th-grade science course for students in Alberta, Canada. This document is the final test for the course. Intended for administration during June 1989, it contains 49 multiple-choice questions and 4 written-response questions. Two-and-one-half hours are allowed for completing the test. No answer key is included since scoring is…

Presented are example activities which are typical of the topic focus and methods of approach evident in the Algebraic Thinking in Children (ATIC) project. This project is aimed at assisting children to ultimately make sense of formal algebra when it is presented. (CW)

In this paper we report some results of the analysis of released items of the Third International Mathematics and Science Study (TIMSS). This analysis is part of a research project in process related to Mexican high school curricula from an international perspective and, the mathematics students' performance in this school level. The results…

Reviews the types of math problems grade 7 and grade 9 students attempted in class, at home, and on examinations collected during the 1999-2000 school year. Indicates that students were exposed to a variety of problem types, but the level of contextualization was low as was the level of open-endedness of the questions. (Author/KHR)

Two related studies are reported about the (lack of) activation of real-world knowledge in elementary school students' understanding and solution of school arithmetic word problems. In the first study a set of word problems was collectively administered to 75 fifth-graders during a typical mathematics lesson. Half of the problems were standard…

Reviewed are 15 studies on cognitive style and problem solving in science education. The effects of problem context, problem type, and three kinds of cognitive style on subjects' abilities to encounter and solve problems are investigated. Three protocols of the subjects' encountering activities are provided. (YP)

Examines how the wording of statistical problems affects 11-12 year old children's answers. Ninety-six children were given statistical problems on two statistical concepts (base-rate and the law of large numbers). Indicates that the children had a high level of statistical intuition and knew when to reason statistically. (CMK)

The International Mathematics Tournament of the Towns is a mathematics competition for junior and senior high school students all over the world. The tournament began in 1980 in the former Soviet Union. Participants write contest papers locally, with emphasis on solving within a very generous time allowance a small number of interesting problems.…

Describes how informatics is being integrated into the Bulgarian schools' curriculum through the use of microcomputers, Logo, and appropriate software. A set of problems that could be used for introducing informatics is presented which is based on the programming notions of cycle, recursion, and coding. (LRW)

Mathematics 30 is a 12th-grade mathematics course for students in Alberta, Canada. This document is the alternate form for the final test for the course. Intended for administration during January 1989, it contains 45 multiple-choice questions, seven open-ended scannable questions, and three written-response questions. Two and one-half hours are…

Variation in syntactic difficulty in arithmetic problems is studied to determine its influence on students' ability to solve problems correctly. Findings in a study of elementary school students indicated syntactic difficulty affects problem solving ability, regardless of sex (f=fiche number). (MH)

Discusses three types of bridges to determine how best to model each one: (1) drawbridge; (2) balance bridge; and (3) bascule bridge. Describes four experiments with assumptions, analyses, interpretations, and validations. Provides several diagrams and pictures of the bridges, and typical data. (YP)

Mathematics 30 is a 12th-grade mathematics course for students in Alberta, Canada. This document is the final test for the course. Intended for administration during June 1989, it contains 45 multiple-choice questions, 7 open-ended machine scorable questions, and 3 written-response questions. Two-and-one-half hours are allowed for completing the…
