This study examined students' accuracy of measurement estimation for linear distances, different units of measure, task context, and the relationship between accuracy estimation and logical thinking. Middle school students completed a series of tasks that included estimating the length of various objects in different contexts and completed a test…

SI units of work, force, and energy are identified. (BB)

Describes a 45-minute module to instruct elementary school teachers in teaching the metric system. (CS)

A step-by-step procedure for converting a secondhand platform balance to the metric system is outlined for use as a student project. (MP)

A graphical representation is used to construct a line one centimetre in length. (MP)

Describes several studies that challenge conventional wisdom regarding the teaching and learning of nonstandard and standard unit, rulers, and measurement sense. Discusses the educational implications of their results. (Author/CCM)

This study was conducted to determine whether or not elementary teachers are prepared to teach the metric system. The data show that scholars are neither well equipped nor staffed for the teaching of the metric system. (MP)

The metric unit for almost any physical quantity is shown to be defined in terms of one or more of nine elemental units raised to various powers. (MP)

This activity, for grades 7-12, requires students to lay out an arena for training horses. To do this the students compute the sum of metric linear measures, compute the circumference of circles and semi-circles, and use the Pythagorean Theorem. (BB)

Explores the topics and issues that filled this journal during its history. Discusses formally published articles on the prospect of adopting the metric system. (ASK)
