q2 i1 Number of synchronous messages written correlates negatively with note scan rate while reading others' notes (r = −0.18, p = 0.007). → 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 · i1 · associational · r1

Correlational log analysis over all 222 students in the nine courses, using the scan-rate metric defined as reading at eight words-per-second or more. The quote reports "r = −0.18,p = 0.007", so heavier message writers scan less.

"In considering scan rate, we find a significant negative correlation between number of messages written and scan rate while reading other students’ notes ( r = −0.18,p = 0.007)."

Discussion¶

Related Claims¶

• Students who write more synchronous messages also write more asynchronous notes and read more notes (r = .60 and r = .36) — related
• Students who write more synchronous messages spend more time online (r = .61) — related
• No significant correlation between number of messages written and average length of notes written — related
• Students in large online classes scan lengthy notes (over 350 words) more frequently than students in small classes — related
