For over a decade now, technology tools have been advocated to assist student understanding of statistical concepts. We have designed and used applets that simulate sampling and randomization tests as a means for introducing students to concepts of statistical inference. In this talk we present the results of our investigation on the impact of using applets for this purpose with tertiary students. The foci of our investigation include appreciating the reasoning process behind statistical significance, understanding what a p-value is, and recognizing factors that affect p-values. We present the results of small classroom experiments designed to help inform our curricular materials and manner of teaching.
