Subclaims¶

q2 i? The correlation between number of messages written and average length of notes was not statistically significant (p = 0.21); equivalence was not tested. → Murat Oztok 2012

Evidence¶

Murat Oztok 2012¶

Murat Oztok, Daniel Zingaro, Clare Brett, Jim Hewitt. (2012). Exploring Asynchronous and Synchronous Tool use in Online Courses. Preprint submitted to Computers & Education. https://doi.org/10.1016/j.compedu.2012.08.007

q2 · i? · associational · r2

Correlational analysis of logs from all 222 students in nine dual-mode courses, relating messages written to average note length. The quote reports "no significant correlation ( p = 0.21)"; no effect size is printed for this null finding.

"we found a highly significant positive correlation between number of messages written and number of notes written (r = 0.6,p = 0), but no significant correlation ( p = 0.21) between number of messages written and average length of notes"

Discussion¶

Related Claims¶

• 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
• Frequent private-message writers show a lower note scan rate, scanning fewer opened notes (r = −.18) — related
• Synchronous private messages are shorter, easier to read, and use fewer academic words than asynchronous notes in dual-mode online courses — related
• Students write shorter notes as online class size increases — related
