实验室工作是所有化学课程的核心，但关于实验室技能评估的文献很少。在这项研究中，我们报告了以样本视频为基础的同行观察协议的使用。学生需要在实习前观看三种技术(滴定、蒸馏、制备标准溶液)的示范视频，并在接受复习的同时向同龄人演示该技术。对于其中的两种技术(滴定和蒸馏)，演示过程是在手机上拍摄的，这提供了学生成功完成技术的证据。为了培养学生的数字素养技能，学生需要将他们的视频上传到视频共享网站上，供教师审查。该活动促进了向成功证明能力的学生发放数字徽章。作为活动的结果，学生们对他们的知识、经验和对与每种技术相关的一系列方面的信心的评分显著提高。报告了这项工作以及学生对问题的回答、视频访问和实施过程中的观察，以便展示一种新颖和有用的方式，将同行评估实验室技能纳入实验室方案，并使用数字徽章作为一种手段，根据学生产生的证据纳入和记录可转让的技能。
Laboratory work is at the core of any chemistry curriculum but literature on the assessment of laboratory skills is scant. In this study we report the use of a peer-observation protocol underpinned by exemplar videos. Students are required to watch exemplar videos for three techniques (titrations, distillations, preparation of standard solutions) in advance of their practical session, and demonstrate the technique to their peer, while being reviewed. For two of the techniques (titrations and distillations), the demonstration was videoed on a mobile phone, which provide evidence that the student has successfully completed the technique. In order to develop digital literacy skills, students are required to upload their videos to a video sharing site for instructor review. The activity facilitated the issuing of digital badges to students who had successfully demonstrated competency. Students’ rating of their knowledge, experience, and confidence of a range of aspects associated with each technique significantly increased as a result of the activity. This work, along with student responses to questions, video access, and observations from implementation are reported in order to demonstrate a novel and useful way to incorporate peer-assessment of laboratory skills into a laboratory programme, as well as the use of digital badges as a means of incorporating and documenting transferable skills on the basis of student generated evidence.
