Subclaims¶

q2 i? Adding key frames to dynamic visualizations of first aid procedures produced better posttest performance than dynamic visualizations or key frames alone. → Spanjers 2010 q2 i? Revealing key frames sequentially led to better posttest performance than presenting them all at once, and presenting twice as many frames had a negative effect that tended to disappear when presented sequentially. → Spanjers 2010 (2)

Evidence¶

Spanjers, I. A. E., van Gog, T., & van Merriënboer, J. J. G. (2010). A Theoretical Analysis of How Segmentation of Dynamic Visualizations Optimizes Students' Learning. Educational Psychology Review. https://doi.org/10.1007/s10648-010-9135-6

q2 · i? · review · r3

The review reports Arguel and Jamet's (2009) experiment 1 comparing dynamic visualizations with key frames, without key frames, and key frames alone for first aid learning; the combined condition had better posttest performance. No effect size is printed.

"The addition of the key frames to the dynamic visualization may have served as a cue of the underlying structure of the shown procedures, and this condition had better posttest performance than the other conditions."

q2 · i? · review · r2

The review reports Arguel and Jamet's (2009) experiment 2 on timing of key frame presentation; sequential revelation led to better posttest performance than presenting all frames at the start. No effect size is printed.

"In their second experiment, Arguel and Jamet ( 2009) showed that revealing the key frames sequentia lly (after which they remained visible) led to better posttest performance than prese nting them at once at the beginning of the dynamic visualization."
