A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets. 相似文献

It is often difficult to transfer learning from one situation to another. Learning is more likely to be transferred if instruction is situated within a realistic context, using a problem‐centered instructional approach. However, it can be challenging to create problem‐centered instruction that authentically represents the needs and activities of the workplace and profession. This article describes the problems of practice approach––an iterative, guided process for developing problems for problem‐centered instruction. 相似文献

ABSTRACTThis article centres on a reunion held at the National Football Museum in 2018 of women football players active before 1993, particularly the England team for the unofficial Women's World Cup in 1971. After outlining the organisation of the tournament, the experience of the three youngest England players is articulated using oral history case studies. Finally the argument suggests that social strategies, such as reunions, enable a degree of reminiscence therapy and provide museum and archives with potential material, currently in the private domain, to build contemporary collections, provided that players are willing to gift or loan their items. 相似文献

Brian Griffiths (1927–2008) was a British mathematician and educator who served as a member of the founding editorial board
of Educational Studies in Mathematics. As a mathematician, Griffiths is remembered through his work on what continue to be known as ‘Griffiths-type’ topological
spaces. As a mathematics educator, his most profound contribution was, with Geoffrey Howson, in offering a conceptualisation
of the relationship between mathematics, society and curricula. 相似文献

AbstractTo be successful, junior faculty must properly manage their time in the face of expanding responsibilities. One such responsibility is supervising undergraduate research projects. Student research projects (either single or multi-student) can be undertaken as a full-time summer experience, or as a part-time academic year commitment. With many potential undergraduate research formats, and with different types of students, junior faculty may find challenges in forming their research group, establishing a structure that promotes student productivity, picking an appropriate project, or in effectively mentoring their students. This article draws from the authors’ experiences to help junior faculty navigate these complexities so that all parties reap the benefits of undergraduate research in interdisciplinary mathematical disciplines. 相似文献

The paper addresses the way in which participants in a qualitative study drew upon accounts of relationships and emotions in sharing their perceptions of assessment. By first exploring ideas about emotions and relationships in learning and assessment through the literature and subsequently discussing an interpretation of participant narratives, the author suggests that emotions and relationships surrounding past learning and assessment contexts can influence current perceptions of assessment and learning in powerful ways. The study also reveals how students value opportunities to express their beliefs, feelings and emotions during the assessment process. They also expect teachers to balance objectivity in assessment with empathy for those parts of themselves shared in the process. The conclusion is drawn that there are important implications for learning in the emotional response of students to assessment and in the nature of teaching and learning relationships that are worthy of further investigation. 相似文献

The authors used a pretest-posttest control group design with random assignment to evaluate whether early reading failure decreases children's motivation to practice reading. First, they investigated whether 60 first-grade children would report substantially different levels of interest in reading as a function of their relative success or failure in learning to read. Second, they evaluated whether increasing the word reading ability of 15 at-risk children would lead to gains in their motivation to read. Multivariate analyses of variance suggest marked differences in both motivation and reading practice between skilled and unskilled readers. However, bolstering at-risk children's word reading ability did not yield evidence of a causal relationship between early reading failure and decreased motivation to engage in reading activities. Instead, hierarchical regression analyses indicate a covarying relationship among early reading failure, poor motivation, and avoidance of reading. 相似文献
