摘要

在这次演讲中,我们讨论了数字技术在提供实践或“动手”课程时促进学生自主学习的能力。我们还研究了当为面对面课程设计的课程突然转移到网上时,影响学习者体验的制约因素。我们使用了一个案例研究,该案例研究了在新西兰爆发Covid-19导致2021年突然实施4级封锁后,一篇实用的多媒体本科新闻论文是如何在学期中途从面对面转移到在线交付的。该案例研究展示了在教学框架内设计的课程如何在危机时刻成功地进行调整,同时保持所需的学习成果。我们的经验为新闻业等实践性活动的教学提供了实证讨论点,在这些活动中,受限的流动性实际上可以带来学生主动提出的成长机会,而不是阻碍。从学年开始,我们的方法就是培养学生的数字能力,引导他们成为自己学习的主体(Hase & Kenyon, 2007;Blaschke & Hase, 2019)。我们意识到,新冠肺炎疫情在新西兰不断发展,政府的指示可能会要求我们的大学在短时间内将课程转移到网上。因此,本案例研究不应被视为“紧急远程教学”的纯粹例子(Hodges et al. 2020)。该设计采用了社会建构主义的方法(Lockey, Conaghan, Bland & Astin, 2020;Vygotsky, 1930-34/1978),包括体验式学习和反思,以提高学生的独立性和准备。然后在此基础上使用连接主义原则(Siemens, 2004)将个人与班级联系起来,包括采用协作式同伴学习。我们的计划考虑了在线吸引学生的不太成功的尝试(Cowie & Sakui, 2019年)以及我们在2020年封锁期间吸取的教训。我们认为学生的参与度、学生对所需技术的获取以及他们的数字能力水平将是我们面临的最大挑战(Greenhow & Lewin, 2021)。我们采用的学习策略包括模仿新冠肺炎封锁期间专业记者采用的文化和新兴做法。策略是在在线课堂环境中制定的,这种环境培养了专家般的思维,使学生能够自主活动,建立在小组合作和基于游戏的学习基础上。我们鼓励在学生与讲师的互动中保持高度的灵活性,并且围绕健康进行定期讨论。我们发现学生们寻求更多的机会与他人交流,因为许多学生离开家,没有社会支持系统。在设计课程时,我们将自己的角色概念化为“学习经验的设计师”(Cochrane & Munn, 2020,第2页)。因此,我们通过增加社交媒体技术的应用来模拟新兴的新闻实践,并通过同行评审嵌入批判性分析,从而在学生中实现了比以前的新闻论文更高的参与度。实际成果包括制作每周多媒体新闻简报/模拟广播行业新闻广播,并在一个专门建立的网站上发布,以及由多媒体解说员支持的学生电子作品集。

Technology-enhanced learning in designing for uncertainty
In this talk, we discuss the affordances of digital technologies to facilitate student-determined learning when delivering practical or ‘hands-on’ courses. We also examine the constraints that affect the learner experience when courses designed for face-to-face classes suddenly move online. We use a case study of how a practical multimedia undergraduate journalism paper was moved from face-to-face to online delivery mid-way through the semester after an outbreak of Covid-19 in New Zealand led to a sudden imposition of a level-4 lockdown in 2021. The case study demonstrates how the delivery of courses designed within a heutagogical frame work can successfully be adapted at a time of crisis while maintaining the learning outcomes required.   Our experience provides empirical discussion points on teaching a practiced-based activity such as journalism, where restricted mobility can in fact lead to student-initiated opportunities for growth rather than being a hindrance.  Our approach from the start of the academic year was to develop our students’ digital capabilities and guide them towards being agents of their own learning (Hase & Kenyon, 2007; Blaschke & Hase, 2019).  We were aware that the situation with the Covid-19 outbreak was evolving in New Zealand, and government instructions could require our university to move courses online at short notice.  Therefore, this case study should not be considered as a pure example of “emergency remote teaching” (Hodges et al. 2020). The design took a social constructivist approach (Lockey, Conaghan, Bland & Astin, 2020; Vygotsky, 1930-34/1978) that included experiential learning and reflection to increase students’ independence and preparedness. It then built on this using connectivism principles (Siemens, 2004) to link the individual to the class, including employing collaborative peer learning. Our planning took account of less successful attempts to engage students online (Cowie & Sakui, 2019) as well as the lessons we learned during the lockdown in 2020. We considered student engagement, student access to the required technologies and their level of digital competence would be our greatest challenges (Greenhow & Lewin, 2021). Learning strategies we employed included mirroring the culture and emerging practices professional journalists were applying under Covid-19 lockdown.  Strategies were developed in an online classroom environment that fostered expert-like thinking that enabled student-determined activities, founded upon small group collaborations and play-based learning. We encouraged a high level of flexibility in our student-lecturer interactions, and regular discussions around wellness evolved organically. We found students sought increased opportunities to engage with others, as many students were away from home and without a social support system.   When designing the course, we conceptualised our role as “designers of learning experiences” (Cochrane & Munn, 2020, p. 2). Hence we modelled emerging journalistic practices through the increased application of social media technologies, and embedded critical analysis via peer review in a way that achieved a higher level of engagement among the students than had been experienced in previous journalism papers. Practical outcomes included the production of weekly multimedia  news bulletins \modelling broadcasting industry newscasts that were published on a purpose-built website, and student e-portfolios supported by multimedia exegeses.
