Subclaims¶

q3 i? Mean scanning rates differed significantly between small classes (n=77) and large classes (n=168) for notes containing more than 350 words (p<0.05), but not for shorter notes. → Hewitt 2007

q3 · i? · associational · r1

Independent samples t-test comparing scanning rates (reading speeds of 8.0 wps or faster, computed from time-stamped log data) between the 10 largest and 10 smallest of the 28 courses. The article reports significant differences (p<0.05) only for notes over 350 words; no significant differences were found for shorter notes.

"An independent samples t-test found statistically significant differences (p < 0.05) between the mean scanning rates of students in small classes (n=77) and those in large classes (n=168) for notes containing more than 350 words. No significant differences in scanning rates were found between small classes and large classes for notes containing fewer than 350 words."

• Frequent private-message writers show a lower note scan rate, scanning fewer opened notes (r = −.18) — related
• Students who write more synchronous messages spend more time online (r = .61) — related
• Students who write more synchronous messages also write more asynchronous notes and read more notes (r = .60 and r = .36) — related
• Students in larger online classes open a smaller percentage of their peers' notes — related
