This study examines the performance of dietitians-in-training on developing a diet plan for a diabetic patient either independently or after peer discussion. Participants (n?=?58) from an undergraduate program in food and nutrition were divided into two groups based on their prior knowledge before being randomly assigned into three conditions: (1) peer discussion with just-in-time information (JIT information), (2) peer discussion without JIT information), and (3) independent performers. The learners’ performance in the three conditions was analyzed. The results presented here describe the role of prior knowledge and JIT information across the conditions and the interaction of the two factors as well as the instructional implications of the findings. 相似文献

This study addressed the argument that online courses rarely use discussion strategies that are specifically designed and constructed for soliciting learners' cognitive presence and higher-order thinking. Prompted by this argument, the authors conducted a meta-analysis of the empirical studies that examined the effectiveness of discussion strategies in online learning. More specifically, the meta-analysis was to reveal whether learners perform better in a strategic discussion session than when they engage in a conventional online discussion and under what conditions the learners' differences in performance are greater or smaller. Furthermore, the investigation examined the extent to which the online discussion strategies that included instructional elements and the pedagogical recommended by the literature make a difference in learners' performance. 相似文献
