Metacognitive training is an emerging cognitive intervention for children with fetal alcohol spectrum disorder (FASD) that teaches children to think about their thinking and use strategies to improve learning and regulation. We investigated how children with FASD acquired metacognitive strategies during a computerized intervention delivered in a school setting. The number, type, and process of strategy acquisition were recorded for seven children with FASD during the intervention. As an indication of strategy learning, we recorded prompted and spontaneous strategy use over time. Children with FASD were found to use a total of 26 different metacognitive strategies, with eight strategies used spontaneously by all participants. Participants demonstrated a significant decrease in the number of different prompted strategies and a significant increase in the number of spontaneous strategies used over the course of the intervention. Implications for the use of a metacognitive approach for students with FASD are discussed, emphasizing the value of a strength-based approach.
