Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i2 In a two-week field experiment with two DokuWiki groups, DDR participants engaged in many more discussions (d = 1.68) and made fewer edits (d = 0.51) than BRD participants. → Heimbuch 2018
Evidence¶
Heimbuch 2018¶
Heimbuch, S., Ollesch, L., & Bodemer, D. (2018). Comparing effects of two collaboration scripts on learning activities for wiki-based environments. University of Duisburg-Essen. https://doi.org/10.1007/s11412-018-9283-0
q2 · i2 · causal · r2
Main-study two-group field experiment with DokuWiki (N = 69 completing all stages); Welch's t-tests on wiki log metrics: edits BRD M = 12.47 vs DDR M = 7.43, t(63.09) = 2.11, p = .019, d = 0.51; discussions BRD M = 0.28 vs DDR M = 13.87, t(36.45) = 7.48, p < .001, d = 1.68.
"Regarding the wiki contributions, students in the DDR group participated much more frequently in talk page discussions and edited less to the wiki articles than students in the BRD group (cf. Table 6)."
Discussion¶
Related Claims¶
- Wikipedia's bold-edit collaboration script led to lower article quality than a discussion-first alternative script — related
- In the main study, BRD articles were longer, but DDR articles had a lower relative error rate, and article length correlated positively with errors
- In the main study, learning gains from pre-test to post-test were not directly influenced by the collaboration script, though all students improved significantly over time — related
- In the pre-study, dyads using the DDR script were far more likely to integrate their partner's evidence into their answers on the main topic question — related
- In the main study, NCC, metacognitive strategies, and intrinsic motivation moderated contribution frequency but showed no significant conditional effects on learning gains — related
- In the main study, wiki contribution frequency indirectly mediated the effect of script on post-test learning, while the direct script effect was not significant — related
