Abstract: In this paper, an on-line laboratory is described in which students can test theoretical analyses of the run-time efficiency of common sorting algorithms. The laboratory contains an applet that allows students to select an algorithm with a type of data distribution and sample size and view the number of compares required to sort a particular instance of that selection. It provides worksheets for tabulating the results of a sequence of experiments and for entering qualitative and quantitative observations about the results. It also contains a second applet that directly measures the goodness of fit of recorded data with common functions such as cn2 and cn(lg(n)). The laboratory is intended to reinforce classroom learning activities and other homework assignments with a practical demonstration of the performance of a variety of sorting algorithms on different kinds of data sets. It is a singular on-line tool that complements other online learning tools such as animations of various s orting algorithms and visualizations of self-adjusting data structures. The laboratory has been used in algorithms courses taught by the author at Marist College and Vassar, and is available on-line for use by a more general audience. (More)
