- PublicationEmbargoBreaking the silence: Understanding teachers’ use of silence in classrooms
Silence in classrooms is an undervalued and understudied phenomenon. There is limited research on how teachers behave and think during teachers’ silence in lessons. There are also methodological constraints due to the lack of teacher’s talk during silence. This study used eye-tracking technology to visualize the noticing patterns of two science teachers during silence lasting more than three seconds. Using video data recorded from cameras and eye trackers, we examined each silent event and interpreted teachers’ perceptions and interpretations with consideration of eye fixations, actions of students and teachers during the silence, and teachers’ actions immediately after they broke the silence. We further examined expert-novice differences in teachers’ use of silence. Four categories of teachers’ silence were identified: silence for (1) preparing the classroom for learning; (2) teaching, questioning, and facilitating learning; (3) reflecting and thinking, and (4) behavioural management. Expert-novice differences were identified, especially in the teachers’ use of silence for approaches to teaching, reflection, and behavioural management. The novel contribution of this paper lies in the characterization of silences as observed in actual classroom settings as well as the methodological innovation in using eye trackers and video to overcome the constraints of lack of talk data during silence.

To this end, we review research works in artificial intelligence (AI) and immersive technologies which have been applied to facilitate STEM learning. Through a systematic literature search, we identified 82 papers and analyzed them for three aspects—(1) types of emerging technologies used, (2) science education goals, and (3) implementation value. Our findings indicate that augmented reality and natural language processing are common technologies used to enhance students’ learning experiences. These technologies helped students build conceptual understanding as well as epistemic practices in science. On the other hand, mixed reality and computer vision were the least popular technologies, which may be indicative of the low maturity of these technologies. Of all the science education goals, social aspects were the least commonly tackled through emerging technologies. Moreover, 58.9% of technological applications transformed science teaching and learning through automated ways of providing individualized feedback to students involved in argumentation and reasoning activities. Finally, based on our findings, we derive three research agenda that we believe would further the eventual implementation of emerging technologies in schools.

Using cogenerative dialogues to create a safe environment to address emotional conflicts in a project-based learning science internship. In her paper, she presented how cogenerative dialogues can be used to create an emotionally safe environment for conflict resolutions in a project-based science internship program. She examined the emotions during the cogenerative dialogues using the polyvagal theory. Here, we continue the discussion by raising alternative perspectives to view the events, particularly the “Lucy incident” that was described. We suggest the use of emotional regulation strategies such as situation selection, situation modification, attention deployment, cognitive change and response modulation as a means to enhance the way cogenerative dialogues could be carried out. The main argument on this commentary is that strong emotions cannot be dismissed if cogenerative dialogues are used as a means to resolve conflicts. Rather, participants in cogenerative dialogues need to apply specific emotional regulation strategies so that they can contribute and participate in cogenerative dialogues more constructively.
