Although writing learning journals is a powerful learning tool, instructional support is needed to overcome deficits in the use of self-regulated learning strategies. In a 2 x 2 experimental design with high-school students (N = 70), we analysed the effects of two modes of instruction (namely, informed prompting and learning-journal example) along with prompts. Informed prompting that provided background information on the prompted strategies enhanced learning in the training and transfer session. A learning-journal example that modelled the application of the strategies primarily fostered the strategy used in the training session and learning in the transfer session. Theoretically, the results provide support for the self-regulation view of writing-to-learn. (Contains 1 figure and 2 tables.)
