Subclaims¶

q2 i? Inexperienced trainees benefitted from textual explanations integrated into circuit diagrams, while more experienced trainees performed significantly better with a diagram-only format, so the split-attention effect for novices was replaced by the redundancy effect for experts. → Kalyuga 2003 q2 i? Integrating explanatory notes into primary text assisted low language-competence learners but retarded learning for more knowledgeable learners because the redundant notes were difficult to ignore. → Kalyuga 2003 (2)

q2 i? The article cites reviewed evidence that instructional manipulations effective for novices, including integrated formats, can be counter-productive for more experienced learners, as illustrated by electrical trades trainees for whom a diagram-only version outperformed integrated and split-source versions after training. → Ginns 2006

q2 · i? · review · r2

The review attributes this to Kalyuga et al. (1998): in experiments with electrical trainees, novices needed integrated text but more experienced trainees did significantly better with diagrams alone and reported lower mental effort, so "The split-attention effect for novices was replaced by the redundancy effect for experts."

"Kalyuga, Chandler, and Sweller (1998) found that inexperienced electrical trainees benefitted from textual explanations integrated into the diagrams of electrical circuits (to reduce split attention). They were not able to comprehend a diagram-only format. However, more experienced trainees performed significantly better with the electrical circuit diagram-only format."

q2 · i? · review · r2

The review reports, citing Yeung, Jin, and Sweller (1998), a textual study showing that integrated explanatory notes helped low language-competence learners but "retarded learning for more knowledgeable learners."

"Integrating explanatory notes into the primary text assisted learners with low levels of language competence. The same format retarded learning for more knowledgeable learners because the integrated notes, although redundant, were difficult to ignore when integrated into the primary text."

q2 · i? · quant-synthesis · r2

The discussion cites Kalyuga et al. (1998), reported in the article as finding that after domain training, the diagram-only version outperformed integrated and split-source versions — a redundancy effect limiting the generalisability of integration benefits to novices. This is a cited study narrated in the discussion, not re-analysed in the meta-analysis.

"Following training to increase expertise in the specific domain, those who studied a diagram-only version of the materials outperformed those in the other conditions, indicating that a redundancy effect – that is, more experienced students could rely on their schemas to comprehend and learn from the diagrammatic materials"

Related Claims¶

• The learning benefit of increasing integration is substantially larger for high element interactivity (complex) materials than for low element interactivity materials — the general claim this finding bears on, with the studies behind it

• Split-attention worked examples lose their advantage over conventional practice, while integrated formats restore it — related
• Split Attention Effect Degrades Learning — the general claim this finding bears on, with the studies behind it

• Embedded explanatory notes improved Shakespearean text comprehension for novice readers but reversed for experts — possibly the same claim (merge candidate)
• The expertise reversal effect reflects the strength of experts' knowledge base resisting redundant external information, and a motivation-related form is predicted — a broader claim this one bears on
• Split-attention and redundancy effects occur for high element interactivity material but disappear for low element interactivity material — related
• The review reports that worked examples benefit inexperienced learners but become redundant with increased experience, when problem solving proves superior — related
• The review reports that the modality effect reverses with expertise: audio-visual presentations helped inexperienced learners, but after further training a diagram-only condition showed a substantial advantage — related
• Step-linked visual grounding externalizes spatial reasoning: synchronized diagrams that reveal auxiliary lines step by step reduce split-attention effort — related
• Redundancy effect: when one source of information is intelligible in isolation, physically integrating it with another source fails to help and eliminating the redundant source facilitates learning — related
