Fig. 2 Pattern of cluster variable mean values for the three faculty types demonstrating strong differences in reported behavior between groups; data were combined across all three survey years (2004, 2009, and 2012). The blue line represents education-focused faculty, the red line represents geoscience research–focused faculty, and the green line represents teaching faculty. Error bars represent 95% confidence interval (table S8).
Fig. 4 RTOP scores obtained from observations of faculty who had (i) neither participated in a Cutting Edge workshop nor used the website, (ii) used the website only, or (iii) both used the website and participated in a Cutting Edge workshop. The full range of scores for each group is indicated by a thin vertical line. The interquartile range (approximately 50% of scores) is represented with a box with a horizontal line delineating the median. *Bonferroni post hoc tests from an analysis of variance (ANOVA) test (F = 22.6; P < 0.001) indicate a significant difference in mean RTOP scores between group 3 [those who use the Cutting Edge website and attend workshops (M = 48.2, SD = 16.2)] and the other two groups [group 1 (M = 33.1, SD = 13.6); P < 0.001; group 2 (M = 37.2, SD = 13.1); P < 0.001].
