Abstract

This research investigates the preference for a graphical method (structured flowcharts) or for a verbal method (pseudocode) when learning short, relatively complex algorithms. The research summarizes the data from 6 replications using 193 students of data structures and 16 data structures classes. A preference for flowcharts was hypothesized under eight conditions. All eight conditions produced large differences which were statistically significant, p
