A Comparison of an Individual Laboratory Method with a Group Teacher -Demonstration Method in Teaching Measurement and Estimation in Metric Units to Preservice Elementary Teachers.
Pigford, Valma Darleen
Two methods of instructing preservice elementary teachers in the metric system are compared in this study. In the laboratory method 28 subjects handled equipment and participated in measurement and estimation activities. The 29 subjects in the lecture demonstration group met as a class and individually recorded results of the same activities performed by the lecturer. All students covered four units dealing with length, weight, capacity, and temperature. Tasks within units were directed to four objectives: selecting appropriate units, reading instruments, converting between units, and estimating quantitative properties of familiar objects. Student progress was measured by pretest, posttest, and retention test, each consisting of 31 multiple-choice and 5 short-response items. All materials were experimenter developed. Covariate analyses and t-tests were used in data analysis; an alpha level of .05 was specified. No differences between groups were discovered on either the posttest or the retention test. Within groups all differences among pretest, posttest and retention test scores were shown to be significant. On the basis of these results the author recommends that the lecture demonstration method be used in situations where cost-effectiveness is a consideration. (SD)
