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 i? The experimental group completed the physical post-test significantly faster than the control group. → Giles Westerfield 2015
q2 i? There was no significant difference between groups in the number of errors made during the physical post-test. → Giles Westerfield 2015 (2)
Evidence¶
Giles Westerfield 2015¶
Giles Westerfield, Antonija Mitrovic & Mark Billinghurst. (2015). Intelligent Augmented Reality Training for Motherboard Assembly. Int J Artif Intell Educ 25:157–172. https://doi.org/10.1007/s40593-014-0032-x
q2 · i? · causal · r2
In the physical post-test, participants reassembled the five components without tutor help. The experimental group's mean completion time was 56.56 s (SD 11.31) versus 81.13 s (SD 21.11); participants "completed the physical task significantly faster than their peers (t(14) = 2.9, p<.0 2)".
"There was no significant difference on the number of errors made, but the experimental group participants completed the physical task significantly faster than their peers (t(14) = 2.9, p<.0 2)."
Giles Westerfield 2015 (2)¶
Giles Westerfield, Antonija Mitrovic & Mark Billinghurst. (2015). Intelligent Augmented Reality Training for Motherboard Assembly. Int J Artif Intell Educ 25:157–172. https://doi.org/10.1007/s40593-014-0032-x
q2 · i? · causal · r1
Error counts in the physical post-test were 0.50 (SD 0.93) for the experimental and 1.00 (SD 0.93) for the control group; the article reports "no significant difference on the number of errors made". Equivalence was not tested.
"The errors generally fit into two categories: failing to match a name with the correct component, or incorrectly performing an installation procedure. There was no significant difference on the number of errors made"
Discussion¶
Related Claims¶
- Intelligent AR tutoring produces significantly higher post-test performance than non-intelligent AR training for motherboard assembly — related
- BKT students completed posttest problems significantly faster than Control students, with DRL showing marginal advantages in time and solution optimality — a broader claim this one bears on
- Participants rated both AR tutors positively, with no significant between-group differences in questionnaire ratings — related
- Post-experimental questionnaire ratings favoured MT-ITS numerically but the differences between conditions were not significant — related
