Multidimensional analysis of learner satisfaction (paired sample t-test, bonferroni correction).

Dimension	Pre-test Mean (SD)	Post-test Mean (SD)	Effect size (r)	95%CI	t-value
Accuracy	3.2 (0.8)	4.2 (0.6)	0.68**	[0.82,1.18]	12.37
Richness	3.0 (1.1)	3.9 (0.7)	0.61*	[0.65,1.13]	9.84
Targeting	3.0 (0.9)	4.1 (0.5)	0.73**	[0.91,1.29]	14.25
Understandability	3.5 (0.7)	4.3 (0.6)	0.64*	[0.71,1.27]	10.92

Based on a 7-point Likert scale (1 = extremely dissatisfied, 7 = extremely satisfied); pre- and post-intervention comparisons for the same learners (n = 760); *p < 0.05, **p < 0.01, ***p < 0.001.
