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…

Scaffolding is one of the critical features in a problem-based learning environment to address challenges associated with problem solving. While transfer of responsibility is considered as an ultimate goal in scaffolding that is adaptive and contingent, it is rarely studied and practiced. Thus, the purpose of this study was to inform a deeper…

The focus of this research project was to examine how problem- based learning (PBL) impacts students' interest and knowledge in computer science (CS) at the elementary level. By focusing on a problem that emphasizes social activism, we hypothesized that PBL CS could increase interest for students. We employed an iterative design-based research…

This article advances a continuing line of inquiry into an innovative teacher-support program intended to help in-service history teachers develop professional teaching knowledge for inquiry-based history instruction. Two prior iterations informed our design and use of professional development materials; they also informed the implementation…

For over a decade, we have collaborated with secondary school history teachers in an evolving line of inquiry that applies research-based propositions to the design and testing of a problem-based learning framework and a set of wise practices that represent a professional teaching knowledge base for implementing a particular model of instruction,…

This article advances a continuing line of inquiry into the potential of digital educative curriculum materials to support teachers' development of professional teaching knowledge. Instead of standalone levers of change, the educative curricula in this study were featured resources within a novel professional development approach. The qualitative,…

This paper reports on a design experiment of web-based curriculum materials explicitly created to help social studies teachers develop their professional teaching knowledge. Web-based social studies curriculum reform efforts, human-centered interface design, and investigations into educative curriculum materials are reviewed, as well as…

Inquiry-based history instruction is rare in most school settings, but particularly in classes of students who are perceived to be "low achieving." Students with low reading abilities or test scores typically receive instruction focused on rote recall of historical information. Teachers and students face great obstacles in inquiry based learning,…

The Persistent Issues in History Laboratory for Virtual Field Experience (PIH-LVFE) combines a database of video cases of authentic classroom practices with multiple resources and tools to enable pre-service social studies teachers to virtually observe teachers implementing problem-based learning activities. In this paper, we present the results…

This research extends a continuing line of inquiry investigating how multimedia resources might be joined with other support structures to effectively implement problem-based inquiry (PBI) activities in secondary history classrooms. Two history teachers with experience in PBI implemented a technology-supported problem-based civil rights unit in…

This study examines online messages in a discussion forum that a group of K-12 history teachers used to discuss curriculum implementations as part of their professional development. It has 3 main research foci. First, it focuses on identifying the types of assistances provided to the teachers in an online forum. Second, it examines teachers'…

Advances a line of research that investigates the potential of hypermedia resources and scaffolding for supporting problem-based social studies and developing critical reasoning. The line of inquiry consists of a series of generative design experiments that informs problem-based curriculum development. The experiments examined 11th grade U.S.…
