Description¶
The article argues that teaching happens in series while methodology tests are typically done in parallel, implicitly assuming no interaction effects. Its replicated 2×2 serial trial found a replicable interaction effect, leading the authors to state that "parallel modes of testing, even in an RCT format, might mislead and that lessons plans in series should be considered for fuller testing".
Accounts¶
- Test lesson plans in series rather than in parallel, because serial designs expose interaction effects between teaching modes that parallel designs miss: The article argues that teaching happens in series while methodology tests are typically done in parallel, implicitly assuming no interaction effects.

(Buchan et al. (2020))
Claims¶
- Serially taught lesson combinations produce replicable positive interaction effects, with the two most effective schemes showing positive interaction terms [+M]
- The four schemes of work showed replicable significant heterogeneity in effectiveness, with the predicted-least-effective teacher-centred/non-human scheme among the most effective [+M]
