| Abstract: | 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. |
