In order to systematically grasp the research hotspots and evolution of technology affordances at home and abroad, and clarify the characteristics and development direction of technology affordances research in China, we use CiteSpace software to visualize and analyze the research literature on technology affordances at home and abroad. The research results of technology affordances at home and abroad are increasing, and the number of scholars who have researched technology affordances is large, but the cooperation among authors is generally scattered;among foreign research on technology affordances, information technology, knowledge technology, artificial intelligence, digital technology and web 2.0 are the hot spots of research;among domestic research on technology affordances, the connotation of technology affordances, social media, interaction design and user purchase are the hotspots;there are differences in the research frontiers of technology affordances research at home and abroad, but they all focus on the field of social media.展开更多

Adopting a narrative research, this paper discusses eight excellent EFL student teachers＇ perception of affordances for learning to teaching beyond the classroom based on the theories of affordance and niche.

By social learning space we refer to a facility in which students come together in order to learn with and from each other in a non- formal setting. To explore the social learning dynamic in this environment, we carried out a longitudinal ethnographic inquiry. Data came primarily from interviews with learners and administrators, supported by participant-observations. A thematic analysis of the data, informed by ecological and community of practice perspectives, pointed to the emergence of a community of learners and revealed how closely the affordances were connected with the emergent community. In this paper we report on the findings related to the affordances which gave rise to language learning opportunities, the relationship of these affordances to the conditions which supported the development of a community of learners, and the role of learner autonomy in regard to these two interrelated phenomena.展开更多
