Generally speaking, students have difficulty reporting out measurements and estimates of quantities used in the laboratory, and with handling the significant figures associated with them. When required to make calculation involving quantities with different numbers of significant figures, they have difficulty in assigning the corresponding digits…

An in-class activity is described that can be used not only to motivate hypothesis testing, but also to understand and compute the p-value and power in a statistical test. (Contains 3 figures.)

Statistics education is under review at all educational levels. Statistical concepts, as well as the use of statistical methods and techniques, can be taught in at least two contrasting ways. Specifically, (1) teaching can be theoretically and mathematically oriented, or (2) it can be less mathematically oriented being focused, instead, on…

A summary and comparison of the statistical analysis and results of the first three GUME research projects investigating foreign language teaching methods are presented in this report. The methods investigated are the habit-formation or implicit theory and the cognitive-code learning or explicit theory with either source-language or…

Eighth grade students, randomly assigned to three criterion performance levels, studied matrix algebra in three programed lessons. Student achievement, ability, time spent, and other measures were obtained; and minimal variance criterion performance levels, analogous to production isoquants, were attained. A Cobb-Douglas (log-linear) function was…
