Describes a game used in precalculus that builds interest and confidence in the uses of inverse functions. The game is preceded by a worksheet that enables students to discover that f(x) and f-1(x) are mirror images of the line y=x. (DDR)

Four experiments involving 440 college students in the Philippines and United States examined the effects of symbolic knowledge and problem-information context on translating relational statements into mathematical equations. Results indicate that symbolic knowledge is not always easily accessible in contexts that differ from ordinary…

The ability of students to sort cards based on surface features and deep patterns is investigated. The effect of the presence of variables and what makes a pattern difficult or easy for students to recognize are discussed. Study revealed that students are unsuccessful at making connections between expressions, sentences, and sequences which share…

This article is concerned with an average student's understanding of the notion of function. It presents an analysis of a dialogue held with Kasia, a sixteen-years-old pupil of a general academic secondary school. The conversation concentrates on a non-standard problem--a functional equation. The theoretical framework used here is the PROCEPT…

In early algebra students often struggle with equation solving. Modeled on Streefland's studies of students' own productions a prototype pre-algebra learning strand was designed which takes students' informal (arithmetical) strategies as a starting point for solving equations. In order to make available the skills and tools needed for manipulating…

We present a summary of a study carried out with students of the first year of Bachillerato (the first of two pre-university non-obligatory secondary education courses in Spain) to determine and analyse some of their errors and difficulties in learning inequalities with the aim of improving the teaching-learning process of this topic. The study…

Children appear to interpret the "equals" sign as an operator ("adds up to") not a relational ("the same as") symbol--e.g., viewing equations like 13 = 7 + 6 or 8 = 8 as senseless. This study, a natural experiment, examined the effects of long-term instruction emphasizing a relational definition of "equals."…

This publication is designed to acquaint both mathematics teachers and reading specialists with some of the skills students need to read mathematics effectively and to provide sample activities that may be used as a part of mathematics instruction to help students develop these skills. Topics covered include: Specialized Vocabulary and Symbols,…

In a synthesis of literature on reading in mathematics, it was noted that there is a broad basis of research in this area on which to base instruction of definite reading skills important in arithmetic achievement. It was stressed that the vocabulary of arithmetic texts runs at readability levels higher than the performance levels of students in…

This experiment investigated the significance of spontaneous occurrence of number symbols in the drawings of 86 (23 male pairs and 20 female pairs) kindergarten children. A comparison was made of first grade achievement on the Piaget Number Concept Test of students who used alphabetic and numeric symbols in the Draw-a-Classroom Test in…

Offers practical tips on teaching secondary mathematics topics. The ideas are classroom-tested approaches that offer new slants on familiar subjects. The topics discussed include the interpretation of mathematical symbolism in concrete terms, ellipses, and vectors. (PK)

College students were asked to write equations using one of two sets of notational systems. Results indicate that the use of more explicit notation did not help problem-solving performance. (Author/PK)

Measure Up is a research and development project that uses findings from Davydov (1975) and others to introduce mathematics through measurement and algebra in grades 1-3. This paper illustrates the use of generalized diagrams and symbols in solving word problems for a group of 10 children selected from a grade 3 Measure Up classroom. Students use…

Seventh-grade students were tested to uncover arithmetic errors. Answers and intermediate steps were analyzed and models to represent students' behavior were developed. Certain errors were common across students. Others were tied to the format of the test item. Some superficial understandings of mathematical concepts were exposed. (Author/DC)
