Man Lei,Jane Medwell 서울대학교 교육연구소 2021 Asia Pacific Education Review Vol.22 No.2
In March 2020, universities in China transitioned to online education in response to the COVID-19 pandemic and intensified the focus on collaboration in online learning. However, little is known about the impact of undertaking online collaborative learning (OCL) on student teachers’ views about the process and about their own teaching and learning. This qualitative study examined 18 student teachers’ views about their experience of OCL and the way it affected them as learners and future teachers. The participants reported that OCL helped them develop varied views of learning and had a positive effect on their views about the future use of OCL. They saw their personal experience of OCL as an important aspect of their development as teachers. These findings highlight ways that online learning can shape the views and professionalism of student teachers. Future teacher training programs can provide OCL as a teaching experience at an early stage to help transform student teachers’ self-understanding from that of a student to that of a teacher. The findings of this study further reveal that online collaborative teacher training offers student teachers an opportunity to collaborate, discuss, and reflect on their professional development as teachers. This encourages teacher educators to reconsider how new forms of practice and teaching theories can be woven together more effectively in post-COVID teacher training.

External irradiation effect on the growth and evolution of in-flame soot species
Wang, C.,Chan, Q.N.,Kook, S.,Hawkes, E.R.,Lee, J.,Medwell, P.R. Pergamon Press ; Elsevier Science Ltd 2016 Carbon Vol.102 No.-
<P>External irradiation-soot species interaction is a subject that is of great interest due to its existing and future use in research diagnostics, nanomaterial synthesis and energy generation applications. An assessment of the influence of broadband radiation (ultraviolet to infrared wavelengths) on the evolution of soot species within a laminar ethylene-air flame is therefore performed to improve the fundamental understanding of the interaction process. Radiation at an average flux value of 120 kW/m(2) is provided by a solid-state plasma light to the lower region of the flame. Soot samples are collected thermophoretically at flame positions that are close to and downstream from the irradiation location, to assess the effect of external irradiation on the evolution of in-flame soot species. The soot samples are imaged using normal-resolution and high-resolution transmission electron microscopes and the images obtained are analyzed. The application of an external irradiation source is found to increase the soot loading of the flame, and have a pronounced impact on the soot morphology, and influence the in-flame soot growth processes/mechanisms. The effects are also found to persist downstream from the irradiation location. The effects are mainly attributed to the coupling of the broadband irradiation with the soot precursors, for the configurations used. (C) 2016 Elsevier Ltd. All rights reserved.</P>
