The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students’ self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students’ self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students’ understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students’ engineering design self-efficacy and qualitative analyses to identify students’ understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students’ self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students’ understanding of engineering design processes. This research provides insights into the key elements of middle school students’ engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops. 相似文献

On the status of critical theory 总被引:1,自引:0,他引:1
Kai Nielsen 《Interchange》1992,23(3):265-284
Critical theory, while remaining in part a scientific social theory, is not just a scientific theory. The nature and distinctiveness of its criticalness is depicted. The logical status of a rationally reconstructed Habermasian critical theory is displayed, defended from some traditional criticisms (including charges of historical idealism), and contrasted with both historical versions of critical theory and purely scientific theories. Whether the critical theory articulated and defended is Habermasian, or a more historicized critical theory, in either case it is argued that it provides a sound basis forideologiekritik against postmodernist scepticism. 相似文献

In this article we show how a hybridisation of elite sport and school in lower-secondary education in Denmark produces a particular kind of learning subject with dual tracks for development, and we ask what kind of actions the students apply in order to stay becoming along both tracks. We apply theoretical conceptions of ‘becoming’ inspired by Brembeck and Johansson that allow us to understand how the sports students live up to the code of conduct of the sports classes. The article is based on an ethnographic study carried out in four schools located in four regions of Denmark. We argue that the hybrid obliges students to follow a narrow developmental track with an ambitious goal of performing in both sport and school, and that the hybrid is threatened when a sports student prioritises either sport or school while he/she is still enrolled in the class. 相似文献

Preferences for pink and blue were tested in children aged 4–11 years in three small-scale societies: Shipibo villages in the Peruvian Amazon, kastom villages in the highlands of Tanna Island, Vanuatu, and BaYaka foragers in the northern Republic of Congo; and compared to children from an Australian global city (total N = 232). No sex differences were found in preference for pink in any of the three societies not influenced by global culture (ds − 0.31–0.23), in contrast to a female preference for pink in the global city (d = 1.24). Results suggest that the pairing of female and pink is a cultural phenomenon and is not driven by an essential preference for pink in girls. 相似文献

ABSTRACTThis article proposes that Catherine Elgin and Nelson Goodman’s work on exemplification is relevant for discussions within moral philosophy and moral education. Generalizing Elgin and Goodman’s account of exemplification to also cover ethics, the article develops a two-factor account of moral exemplarity. According to this account, instantiation and expressivity are individually necessary and jointly sufficient conditions for someone or something to function as a moral exemplar. Applying this two-factor account of exemplarity to discussions within the philosophy of moral education the article then argues that it is the expressive aspect of moral exemplars, which explains and justifies the educational significance of such exemplars. The article concludes by discussing the similarities and differences between the expressivity account and the transparency criterion formulated by Michel Croce and Maria Silvia Vaccarezza in a recent paper. 相似文献
