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.
q3 i2 The pictorial group significantly outperformed the verbal group on both the immediate posttest (d = .50) and the four-week delayed posttest (d = .40), despite a significant coding-by-time interaction reflecting score decline. → Lee 2017
Evidence¶
Lee 2017¶
Lee, Sunjung. (2017). Raising EFL learners' awareness of L2 lexical errors and correct usage: A dual coding approach. English Teaching, 72(2), 29-50. https://doi.org/10.15858/engtea.72.2.201706.29
q3 · i2 · causal · r2
Follow-up mean comparisons after a significant coding × time interaction, F(1,132) = 4.80, p = .030, ηp² = .04, showed the pictorial advantage held at both intervals; delayed means fell to 7.48 (pictorial) and 5.74 (verbal) of 25, with "t(133) = 2.33, p = .021, d = .40".
"On the immediate test, there was a significant mean difference between the pictorial and verbal group, t(133) = 2.90, p = .004, d = .50. On the delayed test, there was a significant mean difference between the pictorial and verbal group, t(133) = 2.33, p = .021, d = .40."
Discussion¶
Learner Variables¶
- Vocabulary — outcome: instruction changes it
Related Claims¶
- Dual coding elucidation raises adolescent EFL learners' awareness of lexical errors and correct usage more than verbal-only elucidation — related
- Learning style (visual-verbal) shows no significant correlation with the effectiveness of pictorial elucidation for adolescent EFL learners — related
- Adolescent EFL learners perceive cartoon-based pictorial elucidation as helpful for accurate vocabulary use and engagement — related
- Multimedia glosses improve EFL students' vocabulary retention two weeks after treatment relative to no glosses — related
- Vocabulary knowledge gained from eight encounters persisted over two weeks, with no significant immediate-to-delayed test differences — related
- The self-study-before-discussion advantage persisted at one-week delayed tests, with lecture-condition scores declining over time while self-study-condition scores remained stable — related
