This study used an explanatory mixed methods research design to examine the scaffolding strategies of middle school teachers during a design problem-based learning (PBL) unit. Both quantitative and qualitative techniques were used in data collection and analysis, and the findings were integrated for interpretation. Our analysis of classroom…

Case-based reasoning posits that learners can use their prior experience to solve new problems. This theory is cited to explain the benefits of problem-based learning (PBL), especially as it relates to knowledge structure development. However, critics argue that learners lack the relevant knowledge structures to simultaneously learn new content…

This study investigates the effect of "preactional self-regulation" on the quality of problem solving. The experimental study was realized in a problem-based self-regulated learning environment. Data of 78 participants on externalized mental models, re-representing the problem solutions, were collected. A computer-based analysis tool was…

The professional expertise of educational leaders has been defined through the lens of problem-solving processes. Problem-based learning has therefore become an increasingly popular instructional approach in principal preparatory programs. As such, this study represents an initial attempt to explore learning from success (i.e., success-based…

This meta-analysis investigated the influence of assessment on the reported effects of problem-based learning (PBL) by applying Sugrue's (1995) model of cognitive components of problem solving. Three levels of the knowledge structure that can be targeted by assessment of problem solving are used as the main independent variables: (a) understanding…

Lends support to the idea that the quality of the cases used in problem-based learning affects the nature of student learning in this context. Outlines seven principles adapted from research on learning and cognition that can help guide case design. Contains 22 references. (DDR)
