Describes the design of an instrument to measure the attitudes of teachers toward metrication, and reports on its reliability and validity. (GA)

Two instructional approaches and a control group were used in this study. Metric instruction in a college introductory physical science course was divided between: a) Approach A in which volume instruction followed that of length and area; b) Approach B in which volume was stressed but area was not introduced; and Approach C, the control (no…

Investigated secondary mathematics and science majors' understandings of metric relationships and abilities to apply metrics to everyday problems. Differences between groups on the measures were not significant. Both groups understood metric relationships reasonably well, but neither could apply the relationships to everyday situations. (CP)

Seventh-grade students (n=397) were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measuring. Identical metric instruction was used with the exception of activities in estimation for the treatment group. The treatment group retained…

Based on Hovland's four-part statement, "who says what to whom with what effect," opinions were surveyed from preservice elementary teachers (N=139) and mathematics educators (N=45) to establish characteristics of metric educators (who) and content (what) of persuasive communication useful in influencing attitudes of preservice teachers…
