Becoming an Architect: The Role of Work-Based Learning in Architect Training

This article examines the work-based placements of trainee architects in the United Kingdom to examine how trainees become architects. The trainee architects in this study experienced varying levels of participation and responsibility during their yearlong placements. Despite this diversity, developing the trainees on placement was found to be integral to the professional role of the architect. The university-based element of architecture training focused almost exclusively on abstract design while their placements involved practical problem-solving. However, the apparent tension between these elements encouraged the trainees to integrate architectural theory and practice while on placement so they developed both aesthetically and technically. Moreover, the trainees’ presence in the studios helped to nurture fresh design and so helped to feed the central design core of architectural practice. Nevertheless, the trainees’ experience of working in an architectural studio on placement often confounded their expectations of architects’ practice. Yet, becoming an architect retained its personal significance. Issues remain, though, around the unequal access to opportunities on placement and how this inequality might affect trainee architects’ learning.

Results indicated that these two frames interacted with issue involvement and generated different reactions among participants.     

殖民地报业在美国“公民社会”形成中的作用

美国殖民地报业兴起的过程也是美国"公民社会"形成的过程。报业是形成一个公共领域的纽带,属于"公民社会"的范畴,推动了"公民社会"团体的成长。同时,报业的发展孕育了美国"公民社会"思想,形成了北美大陆想象的"公民共同体",并在实践中推动这种"想象的共同体"向现实的"公民社会"过渡,并最终形成了美国"国家——公民社会"的社会结构。本文从殖民地报业的视角,用"公民社会"理论的两分法来分析美国"公民社会"兴起的历史因素。
