Begolli, Kreshnik Nasi; Dai, Ting; McGinn, Kelly M.; Booth, Julie L. – Instructional Science: An International Journal of the Learning Sciences, 2021
Proportional reasoning failures seem to constitute most errors in probabilistic reasoning, yet there is little empirical evidence about its role for attaining probabilistic knowledge and how to effectively intervene with students who have less proportional reasoning skills. We examined the contributions of students' proportional reasoning skill…

Barbieri, Christina A.; Miller-Cotto, Dana; Booth, Julie L. – Journal of the Learning Sciences, 2019
The current study examined the effectiveness of self-explanation prompts, visual signaling cues, and a combination of the two features on middle school students' (N = 202) algebra learning. Also explored were the differential effects of features for students with faulty conceptual knowledge (evidenced by a higher prevalence of making errors during…
