Using multiple representations of a problem can reveal the relationship between complex concepts by expressing the same mathematical condition differently and can contribute to the meaningful learning of mathematical concepts. The purpose of this study is to assess the performances of mathematics teacher-candidates on trigonometry problems…

Each year the New York State Mathematics League (NYSML) and the Atlantic Region Mathematics League (ARML) hold mathematics competitions for secondary school students. This document contains the questions used from 1973 to 1985, and the ARML questions used from 1976 to 1985. For each competition listed the book provides: (1) power questions; (2)…

The third in a series of 3 articles, a study of 30 students was conducted to test the effect of restructuring a unit on trigonometric identities around microcomputer activities based on the themes of educational undercurrents identified in Part II. Experimental-group students scored significantly higher relating trigonometric functions to their…

Developed by the ABCs of Construction National Workplace Literacy Project, these seven workbooks are designed to enhance the basic skills of pipefitters. Reading and Solving Basic Pipefitting Problems #1 defines and uses eight basic terms pipefitters need to know, reviews steps a pipefitter must take to identify and solve a simple pipefitting…
