Problem-based learning (PBL) can take many different shapes but has as a common denominator that it builds on the principles of collaborative, constructive, contextual, and self-directed learning. Systematic review approaches that aim to provide insight in what features make PBL work generally fall short, as they tend to disregard the influential…

The impact of the New Tech Network (NTN) design on several academic measures was tested on ninth graders in four schools in one state located in the Southeastern United States. Research questions explored the extent to which achievement test scores, dual credits earned, and dropout rates differed between ninth grade students in high fidelity NTN…

This study aims to explore the effects of argumentation with the concept map method during medical problem-based learning (PBL) on individual clinical reasoning. Individual clinical reasoning ability was assessed through problem-solving performance and arguments that students constructed during individual clinical reasoning processes. Toulmin's…

Project/problem-based learning (PBL) can provide an effective model for school reform when implemented with fidelity. In the report, "Rising Above the Gathering Storm," it was recommended that if the U.S. is to remain competitive in the 21st-century economy, there must be a serious effort to "enlarge the pipeline of students who are…

In an effort to address K-8 teacher confidence in STEM and increase basic genetics knowledge to a level consistent with its importance in society, we have developed, implemented, and evaluated a 7-day teacher professional development workshop. The overarching goal of our workshop is to facilitate the implementation of innovative DNA-based…

Teachers' problem-based learning knowledge, abilities, and attitudes are important factors in successful K--12 PBL implementations. This article describes the development and use of a free, online module entitled "Design a Problem-Based Learning Experience." The module production, aligned with theories of andragogy, was a partnership…

In the 1970s, Egon Bitner offered a critique of police academy training, signified by the ability to train compliant soldier-bureaucrats rather than competent practitioners. Over the years, subsequent training models have been implemented, evaluated, and modified in an attempt to exceed what has been deemed adequate training. This research…

This article describes two consecutive enactments of technology-oriented teacher professional development designs, aimed at helping teachers find high-quality online learning resources and use them in designing effective problem-based learning (PBL) activities for their students. To align with current professional development prescriptions, in the…

In this study we measured changes in science teachers' conceptual science understanding (content knowledge) and pedagogical content knowledge (PCK) while participating in a problem-based learning (PBL) model of professional development. Teachers participated in a two-week long workshop followed by nine monthly meetings during one academic year…
