Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction. 相似文献

This paper has two objectives: to explicate the sociotechnical conditions that facilitate critique on social media platforms (specifically: Tumblr); and to operationalize a “working theory” from Foucault’s conceptualization of critique. We analyze resistant practices observed (in ethnographic study) in a Not Safe For Work (NSFW) community on Tumblr, arguing that the potential for critique arises there at the intersection of platform architecture and use cultures. Specifically, we show how critique emerges from shared practices of ethics, most visibly enacted through what we call voluntary vulnerability and paying it forward. This potential for critique is arguably at risk with Tumblr’s recent NSFW ban. 相似文献

In the years since Michael Brown’s death, the hashtag #HandsUpDontShoot has been criticized for supposedly misrepresenting forensic evidence as framed by the Department of Justice. However, an expressive pull has kept alive both the hashtag and the sentiment behind it. The images of #HandsUpDontShoot are compelling in that they offer a glimpse into lived experiences that are often dismissed, ignored, or refuted. In this essay, I trace the aesthetic features of the #HandsUpDontShoot images, which foreground shocking juxtapositions between nonviolent protesters and militarized police forces, to the hashtag’s historical analogue: antilynching photography. Antilynching photography often utilized the aesthetic techniques of remediation, recontextualization, and juxtaposition—aesthetic features used prominently in today’s digital and remix cultures. By noting #HandsUpDontShoot’s use of these same techniques, I illuminate the ways in which Twitter’s connective affordances shape the viewer’s encounter with the images to engender ethical witnessing by affectively linking Brown’s death to shared material experiences of racial minorities. Such encounters propel witnesses beyond distanced objectification and toward an embodied reckoning of those experiences. 相似文献

This study examined the influence of spending time outdoors on young children’s physical and socioemotional development. We observed preschoolers’ activities in two naturally provisioned outdoor environments over the course of one year. Eleven preschoolers were videotaped continuously for 16 days at a local river and 9 days at a creek adjacent to the school. In addition to the quantitative analyses of children’s behaviors, a case study of three children’s experiences over the course of the year was conducted. Both the river and the creek settings encouraged a multitude of physical and play behaviors with similar types of affordances, including flat surfaces for running, rocks for climbing and jumping off, and water for exploration and play, but the wilder environment (river) afforded more risk and personal challenges. Observations of children’s motor activities, play and responses to challenging environmental features supported the importance of accumulated experience and social context for the development of confidence in the face of risk, individual exploration and positive social support and engagement with peers. 相似文献

Across the articles in this special issue, there is a clear and important focus on how people learn through mobility, which allows them to move across contexts as they learn. This commentary considers ways mobile technologies can support learning with a focus on understanding the affordances to of the mobile technologies develop new learning practices that could not be accomplished without this technology. With this in mind, we return to the definition of mobile learning that suggests mobile learning is learning across multiple contexts, through social interaction, using personal electronic devices that can immediately capture information about, or provide information to the user. To explore how to implement this definition in truly powerful ways, we suggest explicitly unpacking this into its four component parts, so that we can explore and discuss the unique affordances of mobile learning: (1) multiple contexts, (2) social interactions, (3) content interactions, and (4), capturing information and providing information to users in real-time. We further suggest a 5th element, which is the synergies among these different dimensions. We conclude with the challenges in doing research in mobile learning environments and the need to understand both how and what people learn in such environments. 相似文献

Abstract In two experiments we examined changes in the perception of action possibilities as a function of exertion. In Experiment 1, participants repeatedly climbed on a climbing wall in a series of trials that progressively increased in number to 10 trials, resulting in increased exertion. Before and during climbing, the participants judged their maximum reaching height and perceived exertion. On a separate day, participants climbed another 10 trials while performing actual maximum reaches. Higher perceived exertion was associated with decreases in perceived maximum reach while the actual reaches did not decrease. However, the perceptual changes occurred early during task execution when the participants were not yet fatigued. When exertion set in, neither perceived nor actual maximum reaching appeared to be affected. In Experiment 2, we included exhaustion trials. The findings replicated the early changes in perception observed in Experiment 1, which may be explained by hands-on experience with the task. Furthermore, while climbing to exhaustion, perceptual judgements largely changed in keeping with changes in the actual maximum reach. Thus, there appeared to be a functional relationship between participants' actual action capabilities, rather than their state of physical fatigue per se, and perceived action possibilities. 相似文献

Abstract Affordances mean opportunities for action. These affordances are important for sports performance and relevant to the abilities developed by skilled athletes. In racquet sports such as badminton, different players prefer widely different string tension because it is believed to provide opportunities for effective strokes. The current study examined whether badminton players can perceive the affordance of string tension for power strokes and whether the perception of affordance itself changed as a function of skill level. The results showed that string tension constrained the striking performance of both novice and recreational players, but not of expert players. When perceptual capability was assessed, perceptual mode did not affect perception of the optimal string tension. Skilled players successfully perceived the affordance of string tension, but only experts were concerned about saving energy. Our findings demonstrated that perception of the affordance of string tension in badminton was determined by action abilities. Furthermore, experts could adjust the action to maintain a superior level of performance based on the perception of affordance. 相似文献

It is commonly understood that teachers in secondary school should develop throughout their career in order to stay as an essential factor in student learning. Schools can offer opportunities to link teachers’ professional learning to their school practice with a positive impact on teachers’ motivation to learn and the effectiveness of their learning. In this field study, teachers, school leaders, policy-makers, educational consultants and educational scholars were asked for their perceptions of conditions for teacher learning in school and of interventions in school to enhance teacher professional learning. These conditions and interventions were understood as affordances in schools that enable and support teacher professional learning. The main affordance in school these stakeholders mentioned was an open, but critical way in which teachers share their practices, collaborate and reflect upon their teaching practice. Collaborative practices seem to stimulate many interventions of teacher professional learning in school. Two implications of this finding are discussed. First, we suggest that the maximum teaching time should be reduced, team teaching should be more implemented or classes should be scheduled in such a way that teachers can meet. Second, distributed leadership approaches match with our findings about the role of school leaders in teacher professional learning. 相似文献

Laboratory instruction is critical to the understanding of biology and is a central piece of biological sciences instruction. Although much investigation has focused on the content of biology laboratory exercises, we contend that understanding the extent to which the laboratory materials can aid or limit experimental investigation is of equal importance. In this study, therefore, we investigate the role of timing and availability of laboratory equipment in the context of two different laboratory exercises. We use both case study and an experimental approach to investigate how laboratory materials guide the planning, context, creativity, and timing of ideas shared among students. Our data support the notion that providing students with laboratory equipment before students plan and consider different experimental approaches can constrain students' ideas and encourage tool‐focused solutions to experimental design tasks. © 2011 Wiley Periodicals, Inc.
