Laboratory-based practical classes are a common feature of life science teaching, during which students learn how to perform experiments and generate/interpret data. Practical classes are typically instructional, concentrating on providing topic- and technique-specific skills, however to produce research-capable graduates it is also important to develop generic practical skills. To provide an opportunity for students to develop the skills needed to create bespoke protocols for experimental benchwork, a traditional practical was repurposed. Students were given a list of available resources and an experimental goal, and directed to create a bench protocol to achieve the aim (measuring the iron in hemoglobin). In a series of teaching events students received feedback from staff, and peers prototyped the protocols, before protocols were finally implemented. Graduates highlighted this exercise as one of the most important of their degrees, primarily because of the clear relevance of the skills acquired to professional practice. The exercise exemplifies a range of pedagogic principles, but arguably its most important innovation is that it repurposed a pre-existing practical. This had the benefits of automatically providing scaffolding to direct the students' thought processes, while retaining the advantages of a "discovery learning" exercise, and allowing facile adoption of the approach across the sector. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):377-380, 2016.
基于实验室的实践课程是生命科学教学的常见特色,在此期间学生学习如何进行实验以及生成/解释数据。实践课程通常具有教学性质,专注于提供特定主题和技术的技能,然而,为了培养具备研究能力的毕业生,培养通用实践技能也很重要。为了给学生提供机会来培养为实验操作创建定制方案所需的技能,对一门传统实践课程进行了重新设计。给学生提供了一份可用资源清单和一个实验目标,并指导他们创建一个实验方案以实现该目标(测量血红蛋白中的铁)。在一系列教学活动中,学生们收到了教师的反馈,并且在最终实施方案之前,同学对方案进行了原型设计。毕业生们强调这项练习是他们学位课程中最重要的练习之一,主要是因为所获得的技能与专业实践具有明显的相关性。该练习体现了一系列教学原则,但可以说其最重要的创新之处在于它对现有的实践课程进行了重新设计。这样做的好处是自动提供了引导学生思维过程的支架,同时保留了“发现式学习”练习的优点,并便于该方法在整个领域的采用。© 2016年由国际生物化学与分子生物学联盟出版,44(4):377 - 380,2016年。
