Examining the Design of Media Rich Cognitive Tools as Scaffolds in a Multimedia Problem-Based Learning Environment

Learner acquisition of problem-solving skills is an important education goal, especially as those skills relate to complex problems. Solving complex problems, however, proves to be especially challenging for young learners. Problem-based learning (PBL) is an effective instructional approach that promotes the development of problem-solving skills. When complex, student-centered learning environments such as PBL are implemented, the inclusion of embedded scaffolds can boost motivation and facilitate learning. Technology-based scaffolds within these environments are often called cognitive tools: instruments that can enhance the cognitive powers of learners during their thinking, problem solving, and learning. This paper examines the various cognitive tools embedded in a multimedia enriched PBL environment for middle school science known as Alien Rescue and shares the research findings of the use of these cognitive tools in assisting young learners ’ problem solving. The goal of this paper is to illustrate strategies for designing media rich cognitive tools to support learning
