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…

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…

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 paper explores how teachers with different teaching styles conceptualized and implemented a multimedia-supported problem-based inquiry (PBI) unit. We focus on how the teachers supported student thinking and examine underlying belief, knowledge, and dispositional factors that may account for differences in the teachers' practices. We…

Discussion of student-centered learning focuses on the use of scaffolds. Describes types of scaffolds embedded into a hypermedia database used by eleventh graders in a history class, and examines the types of scaffolds that were most successful at assisting students with information gathering and with assisting with group self-regulation.…

Discussion of the Big Six information skills model focuses on a case study that examines the effect of Big6 on a class of eighth-grade students doing research on the African-American Civil Rights movement. Topics include information problem solving; metacognition; scaffolding; and Big6 as a metacognitive scaffold. (Author/LRW)

The purpose of this research study was to determine whether a specific information problem-solving skills model was an effective metacognitive scaffold for students solving information-based problems. Specifically, 35 eighth grade students in two intact classes were asked to write newspaper articles that summarized the events surrounding the Selma…

This paper explores whether a scaffolded, multimedia learning environment might mitigate obstacles that dissuade teachers from implementing problem-based practices. We present a longitudinal analysis of one expository-oriented teacher's experience with such an environment and examine underlying belief, knowledge, and dispositional factors that may…

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.…
