Subclaims¶

q2 i? Forum messages more often contained social statements and regulative comments than anchored-discussion messages. → van der Pol 2006 q2 i? Forum messages averaged 57 words versus 38 in anchored discussion, with significantly more messages in the anchored condition largely compensating. → van der Pol 2006 (2)

Evidence¶

van der Pol 2006¶

van der Pol, J., Admiraal, W., & Simons, P.R.J. (2006). The affordance of anchored discussion for the collaborative processing of academic texts. International Journal of Computer-Supported Collaborative Learning, 1(3), 339–357. https://doi.org/10.1007/s11412-006-9657-6

q2 · i? · causal · r2

Protocol coding of social and regulative comments across the 36 discussions (Table 5: social comments 42% vs 2%; regulative comments 25% vs 4%). The forum resembled email structure with introductory and closing parts.

"Messages in this condition also more often contain social statements, t(13.82) = 4.46, p = <0.01, and regulative comments, t(14.49) = 3.91, p < 0.01, as can be seen in Table 5."

q2 · i? · causal · r2

Message-length analysis over the complete collection of messages (n = 1,342). Forum messages averaged 57 words versus 38; a significantly larger number of messages per discussion in the anchored condition (t(28.49) = j2.13, p = 0.04) almost completely compensated.

"messages in the forum discussion have an average length of 57 words (see Table 6), whereas their counterparts in the system for anchored discussion, on average, consist of 38 words, t(635.51) 2= 14.17, p < 0.001."
