There is a growing body of research recognizing the relationship between learner strategy use and learning proficiency. The need for life-long learners with advanced learning skills and the ability to self-regulate has motivated this deeper exploration of the ways to enhance learner strategy use towards more self-regulated and skilful learners. This study therefore sets out to assess the significance of interventions reinforced with prompts while supporting cognitive and metacognitive strategy use by learners. An intervention with four learning assignments enhanced with prompts for the treatment group was applied in a sample of 56 undergraduates. The findings confirmed the significance of prompts when supporting learner strategy use. Besides, this study strengthens the idea that metacognitive strategy use has to be supported in combination with cognitive strategies.
