ABSTRACT

Amplified by a global political climate of fear, oppression, and increased nationalism, this article examines how U.S. secondary students in a digital media elective course used multimodal composition, and video production in particular, as a nexus of ‘participatory politics.’ By partnering theories of multiliterate expression with youth civic engagement, it offers new understandings into how urban youth use digital media production to leverage school-based social action. Refracted through a mediated discourse analysis lens, and with a particular focus on sound as a modal resource for design, findings suggest that youth used media production and semiotic sense-making to simultaneously enliven community action as well as shield students from personal histories of trauma. By engaging in the process of digital media production, as this article suggests, students cultivated new core practices of civic interaction and local engagement by amplifying injustice.  相似文献

The parent–adolescent relationship is important for adolescents’ emotion regulation (ER), yet little is known regarding the neural patterns of dyadic ER that occur during parent–adolescent interactions. A novel measure that can be used to examine such patterns is cross-brain connectivity (CBC)—concurrent and time-lagged connectivity between two individuals’ brain regions. This study sought to provide evidence of CBC and explore associations between CBC, parenting, and adolescent internalizing symptoms. Thirty-five adolescents (mean age = 15 years, 69% female, 72% Non-Hispanic White, 17% Black, 11% Hispanic or Latino) and one biological parent (94% female) completed an fMRI hyperscanning conflict discussion task. Results revealed CBC between emotion-related brain regions. Exploratory analyses indicated CBC is associated with parenting and adolescent depressive symptoms.  相似文献

Many online videos feature an instructor on the screen to improve learners' engagement; however, the influence of this design on learners' cognitive load is underexplored. This study investigates the effects of instructor presence on learners' processing of information using both subjective and psychophysiological measures of cognitive load. Sixty university students watched a statistics instructional video either with or without instructor presence, while the spontaneous electrical activity of their brain was recorded using electroencephalography (EEG). At the conclusion of the video, they also self‐reported overall load, intrinsic load, extraneous load, and germane load they experienced during the video. Learning from the video was assessed via tests of retention and transfer. Results suggested the instructor‐present video improved learners' ability to transfer information and was associated with a lower self‐reported intrinsic and extraneous load. Event‐related changes in theta band activity also indicated lower cognitive load with instructor‐present video.  相似文献

The purpose of this research was to design and test a model of classroom technology integration in the context of K-12 schools. The proposed multilevel path analysis model includes teacher, contextual, and school related variables on a teacher’s use of technology and confidence and comfort using technology as mediators of classroom technology integration. Data were collected from 1235 K-12 teachers, who were located in 336 schools in 41 districts across the state of Florida. The results suggest that a teacher’s experience with technology significantly influenced his or her classroom technology integration. Access to technology in classrooms and the availability of quality technology support were related to classroom technology integration. In addition, how frequently a teacher uses technology and his or her confidence and comfort using technology were mediators for classroom technology integration. These results provide preliminary evidence that the proposed model is both useful and relevant in explaining classroom technology integration in K-12 schools.  相似文献

This study was situated within a year-long, statewide technology integration initiative designed to support technology integration within science, technology, engineering, and math classrooms. It examined the elements used in student artifacts in an attempt to investigate trends in digital artifact creation. Among several conclusions, this examination highlighted areas of significant improvement in student use of technology, such as an increase in the creation of PowerPoint presentations and the inclusion of multimedia elements. The study also highlighted areas for improvement, such as the low cognitive demand for content in the majority of the artifacts.  相似文献

Middle-level students have unique emotional and academic needs. As a result, it is important for middle-level educators to realize these needs when creating a caring and engaging classroom climate that results in successful student achievement. This article describes the Caring Community Teaching Model (CCTM), which is a synthesis of affective teaching as well as learning practices tailored to meet the unique needs of middle-grade students. The CCTM is designed as a program with a two-function approach to enhance student engagement: (1) caring relationships and (2) instructional strategies. The authors describe the theoretical framework that underpins the CCTM as well as the emerging literature that creates its needs. Additionally, the CCTM is highlighted through the lens of a case example in which the authors provide concrete examples of CCTM being used in a middle-level classroom.  相似文献

This article reviews content analysis studies aimed to assess critical thinking in computer-mediated communication. It also discusses theories and content analysis models that encourage critical thinking skills in asynchronous learning environments and reviews theories and factors that may foster critical thinking skills and new knowledge construction.  相似文献
