When a course designed around cooperative, problem-centered instruction attracts learners with a wide range of experience in the topic, should learners be grouped heterogeneously or homogeneously in terms of their relative expertise? In this study, learners were randomly distributed between the two types of groups; learning gains, satisfaction,…

The success of an intervention depends not only upon its theoretical soundness, but also on proper implementation that reflects the guidelines derived from its theoretical conception. Debates surrounding the effectiveness of problem-based learning (PBL) have focused on its theoretical conception and students' learning outcomes, but implementation…

This study examines middle school students' learning and motivation as they engaged in a new media enriched problem-based learning (PBL) environment for middle school science. Using a mixed-method design with both quantitative and qualitative data, we investigated the effect of a new media environment on sixth graders' science learning, their…

This paper focuses on theory and research issues associated with the use of hypermedia technologies in education. It is proposed that viewing hypermedia technologies as an enabling infrastructure for tools to support learning--in particular learning in problem-based pedagogical environments involving cases--has particular promise. After…

In this paper we describe the criteria of "Technology I, II, and III," which some instructional theorists have proposed to describe the differences between a formulaic and a reflective approach to solving educational problems. In a recent study, we applied these criteria to find evidence of a "technological gravity" that pulls practitioners away…

A critical step in problem-based learning (PBL) units occurs when groups present their solution to the central problem. This is challenging for middle school students because it involves the creation of an evidence-based argument (Krajcik et al., "Journal of the Learning Sciences" 7:313-350, 1998). Using a mixed method design, this study…

Problem-based learning (PBL) is an instructional approach in which students in small groups engage in an authentic, ill-structured problem, and must (1) define, generate and pursue learning issues to understand the problem, (2) develop a possible solution, (3) provide evidence to support their solution, and (4) present their solution and the…

This article presents a quasi-experimental study comparing the impact of two technology-related teacher professional development (TTPD) designs, aimed at helping junior high school science and mathematics teachers design online activities using the rapidly growing set of online learning resources available on the Internet. The first TTPD design…

This paper reports on a design-based research (DBR) process for designing, implementing, and refining a problem-based learning (PBL) course on educational digital video (DV) use and production at the University of Lapland's Faculty of Education. The study focuses on the students' learning processes and outcomes from the viewpoint of meaningful…

Teachers' implementation of a problem-based learning (PBL) program was examined to determine both how they assessed student learning and their reasons for these assessment practices. Ten 6th grade science teachers used Alien Rescue, a computer-based PBL module, with their students for approximately three weeks. Interviews, observations, and…

Recent research has touted the benefits of learner-centered instruction, problem-based learning, and a focus on complex learning. Instructors often struggle to put these goals into practice as well as to measure the effectiveness of these new teaching strategies in terms of mastery of course objectives. Enter the course evaluation, often a…

This study investigated the effect of well- vs. ill-structured problem types on: (a) group interactional activity, (b) evolution of group participation inequities, (c) group discussion quality, and (d) group performance in a synchronous, computer-supported collaborative learning (CSCL) environment. Participants were 60 11th-grade science students…

Discusses the increased emphasis on problem solving and problem-based learning in instructional design and the need for new methods for task analysis and models for designing instruction. Defines the rationale and means for analyzing, organizing, and presenting stories to support problem solving by case-based reasoning. (Author/LRW)

We present a conceptual framework for scaffolding ill-structured problem-solving processes using question prompts and peer interactions. We first examine the characteristics and processes of ill-structured problem solving, namely, problem representation, generating solutions, making justifications, and monitoring and evaluation. Then, we analyze…

Problem-based learning (PBL) is apprenticeship for real-life problem solving, helping students acquire the knowledge and skills required in the workplace. Although the acquisition of knowledge and skills makes it possible for performance to occur, without self-efficacy the performance may not even be attempted. I examined how student…
