The relationships between social participatory roles and cognitive engagement levels in online discussions

Understanding the relationship between social interaction patterns and cognitive engagement levels has critical implications on collaborative learning theory, pedagogy, and technology. This study used a multi-method approach to examine the relationship between students' social participatory roles and cognitive engagement levels within asynchronous online discussions. Results showed that students' social participatory role was a critical indicator of cognitive engagement level. Socially active students made more cognitive contributions to knowledge inquiry and knowledge construction. But there were exceptions: after taking leadership roles (i.e., discussion designers and facilitators), some students moved from peripheral participation to active participation. Second, there was a progressive development process: individual students' deep-level knowledge inquiry could trigger peer interaction, which could further advance group knowledge construction. Third, students had a tendency to keeping social-cognitive engagement patterns throughout discussions. Based on the result, this study proposed implications for collaborative learning theory, pedagogy support, and tool development.

Regulating surface wrinkles using light

Regulating existing micro and nano wrinkle structures into desired configurations is urgently necessary yet remains challenging, especially modulating wrinkle direction and location on demand. In this work, we propose a novel light-controlled strategy for surface wrinkles, which can dynamically and precisely regulate all basic characteristics of wrinkles, including wavelength, amplitude, direction and location (λ, A, θ and L_c), and arbitrarily tune wrinkle topographies in two dimensions (2D). By considering the bidirectional Poisson''s effect and soft boundary conditions, a modified theoretical model depicting the relation between stress distributions and the basic characteristics was developed to reveal the mechanical mechanism of the regulation strategy. Furthermore, the resulting 2D ordered wrinkles can be used as a dynamic optical grating and a smart template to reversibly regulate the morphology of various functional materials. This study will pave the way for wrinkle regulation and guide fabrication technology for functional wrinkled surfaces.
