This chapter 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 chapter is to illustrate strategies for designing…

Hypothesis development is a complex cognitive activity, but one that is critical as a means of reducing uncertainty during ill-structured problem solving. In this study, we examined the effect of metacognitive scaffolds in strengthening hypothesis development. We also examined the influence of hypothesis development on young adolescents'…

This study investigated whether using multimedia-based instructional material in a problem-based social studies simulation enhances student learning about world issues, increases interest in social studies, and generates positive attitudes toward the instruction. The GlobalEd Project, a Web-based international negotiation simulation embedded in…

GeoThentic, an online teaching and learning environment, focuses on engaging teachers and learners in solving real-world geography problems through use of geospatial technologies. The design of GeoThentic is grounded on the technology, pedagogy, and content knowledge (TPACK) framework as a metacognitive tool. This paper describes how the TPACK…

The momentum gathering behind authentic learning/critical skills raises fundamental issues concerning teaching and learning. This article discusses some of the more general arguments surrounding authentic learning with particular reference to an in-depth evaluation of its impact on schools in one part of Great Britain. It then moves on to describe…

In this paper a multimedia project was incorporated into a problem-based learning environment to examine how learning in multimedia could be enhanced through the use of problem-based learning. Students in a second year course in the Faculty of Creative Multimedia (FCM) were assigned the problem-based multimedia project, they worked in groups,…

The objective of this project was to develop a way of producing instructional materials such that once an acceptable design had been achieved, hypermedia documents could be easily generated with no additional programming or design effort. The project was undertaken to support a case-based instructional curriculum in medical education. Southern…

This study examined whether the inquiry-based problem solving model supports sustained exploration of a multimedia database. This model contains five steps: (1) analyze the discrepant event from which a problem question is generated; (2) generate questions; (3) gather data; (4) analyze information; and (5) evaluate self. A group of 24 seventh…

Examines the role of the tutor in the problem-based learning (PBL) curriculum at the University of Queensland (Australia) dental school, discussing changes in this role across the four years in which PBL is used. Explores different varieties of PBL, as well as group learning, tutor-free groups, the reflective role of tutors, and desirable tutor…

Interactive multimedia (IMM) and problem-based learning (PBL) are both promoted in response to the current need to offer authentic and effective professional education. An emphasis on collaborative work in PBL contexts may have discouraged the application of IMM, more commonly designed for individual use. This paper describes preliminary…

In its use of complex, real-world problems to introduce concepts and motivate learning in an active and cooperative learning environment, problem-based learning is a powerful alternative to the passive lecture in introductory college science. Use of technology and multimedia instruction, focus on large classes, and use of interdisciplinary…
