Abstract

A targeted needs assessment at our institution revealed that the online system used to train researchers on performing techniques with animals did not provide opportunities to practice skills, introduce learners to animal care staff, nor satisfactorily support researchers' needs to become comfortable with laboratory animal species. To correct these deficiencies, a series of hands-on training sessions, framed theoretically in situated learning, was developed. This theoretical framework asserts that learning for everyday living (in this case, performing laboratory animal techniques) happens when people interact within the community while using the 'tools at hand' (that is, the instruments and jargon of the field). From this perspective, the students work alongside the instructor as apprentices. The instructor creates increasingly challenging learning opportunities as students work toward independently performing techniques. To test our hypothesis that teaching from this perspective improves comfort levels with laboratory animals and promotes collaborative relationships between animal care and research personnel, a mixed-method design involving online surveys (first survey, n = 45; second survey, n = 35) and semistructured interviews (n = 10) was used. Quantitative results revealed that students became more comfortable with laboratory animals and were more likely to contact animal care personnel due to participating in the training program. The qualitative arm of the study identified specific features of the training program that improved comfort levels for students (seeing then doing, working in small groups, learning within a comfortable environment, and building collegial relationships). These results support teaching rodent research techniques from the practical and theoretical approach of situated learning.

摘要

我们机构的一项针对性需求评估显示,用于培训研究人员进行动物实验技术的在线系统没有提供技能练习的机会,没有让学习者结识动物护理人员,也没有充分满足研究人员熟悉实验动物物种的需求。为了纠正这些不足,我们制定了一系列以情境学习理论为框架的实践培训课程。这一理论框架认为,日常生活中的学习(在这种情况下,即进行实验动物技术操作)发生在人们在社区内互动并使用“手头工具”(即该领域的仪器和行话)之时。从这个角度来看,学生作为学徒与教师一起工作。随着学生朝着独立进行技术操作努力,教师创造出越来越具挑战性的学习机会。为了检验我们的假设,即从这个角度进行教学能提高对实验动物的熟悉程度,并促进动物护理人员与研究人员之间的合作关系,我们采用了一种混合方法设计,包括在线调查(第一次调查,n = 45;第二次调查,n = 35)和半结构化访谈(n = 10)。定量结果显示,由于参与了培训项目,学生对实验动物更加熟悉,并且更有可能联系动物护理人员。该研究的定性部分确定了培训项目中提高学生熟悉程度的具体特征(先看后做、小组合作、在舒适的环境中学习以及建立同事关系)。这些结果支持从情境学习的实践和理论方法来教授啮齿动物研究技术。
