Reported is a test of retention related to a weight, texture, and force experiment performed by a group of 120 first grade students who had been randomly grouped into three treatment strategies. The results of the retention task, accuracy test, an analysis of the strategies used on both posttests and retention tests, and some miscellaneous post hoc analyses are reported. One strategy in which the students were directed to arrange the objects with those of most value at the end of the row until all were in order, proved to be significantly more effective in training. The method used for the study is presented as well as some of the statistical data gathered in the study. (Author/EB)
