Open-ended learning environments ( OELEs

Meaningful discussion that facilitates reflective thinking can be initiated when learners raise thoughtful questions or provide critical feedback; however, generating effective questions requires a certain level of domain knowledge and metacognitive skills of the question-askers. We propose a peer-questioning scaffolding framework intended to facilitate metacognition and learning through scaffolding effective peer-questioning in online discussion. This framework assumes that novice students who lack domain and metacognitive knowledge can be scaffolded to generate meaningful interactions at an early stage of learning and the resulting peer-generated adaptive questions can facilitate learners' metacognition. Thus, this study investigated the effects of providing online scaffolding for generating adaptive questions to peers during online small group discussion. A field experimental time-series control-group design was employed as a mixed model for the research design. Thirty-nine college students from an online introductory class on turfgrass management participated in the study. The findings revealed that the scaffolds were useful to increase the frequency of student questioning behavior during online discussion. For some students, the online guidance reportedly served as ''a starting point'' to generate questions when they had difficulty asking questions. However, the guidance did not improve the quality of questions and thus learning outcomes. The interview data indicated that peer-generated adaptive questions served a critical role in facilitating learner's reflection and knowledge reconstruction. Further study should focus on the quality improvement of peer-generated questions while considering adaptive and dynamic forms of scaffolding and intermediate factors such as prior knowledge, metacognition, task complexity, and scaffolding type.

The purpose of this study was to investigate the process used by learners to seek, locate, and integrate information resources for use in a project-based environment. Four cases (n=9) were analyzed from an introductory educational technology course during a unit on telecommunications. Participants were asked to generate projects for integrating the Internet into the curriculum. Within this project-based context, learners searched for ir~ormation resources that would accompany their project ideas. Three major findings related to use of hypermedia systems during project-based learning are discussed: (a) progressing from &ta-driven to goal-driven approaches was critical to developing coherent project ideas; (b) consolidation of information resources with project methods and rationales was challenging for learners, often resulting in topic "dr~s" or idea simpt~ication; and (c) metacognitive, domain, and system knowledge appeared critical to achieving coherence in project development. Implications related to the role of instructional scaffolding in encouraging goal-driven and metacognitive processing during open-ended learning are considered.
