“…The work outlined above has informed the design of activities used in the approach described in this work. It is worth mentioning here that other authors that have described the assessment of practical work include the assessment of practical work in high school settings using several stations, (Rhodes, 2010) and a practical exam where students must have competencies to complete the tasks required (Neeland, 2007). However, the direct observation of practical skills for the purpose of assessment appears to be limited to very few reports.…”

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 faciliated 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.

“…Safety in chemical laboratories is a serious business, − but the training for it does not have to be dull, boring, and grinding. By injecting a fun, light-hearted element into this exercise, we believe we have created an examination that students will remember long after their class is completed, and that will impart ideas they can take into academic, corporate, and government laboratories where they will work in their futures. ,, Future versions of the practical will include a more direct link to the ACS R.A.M.P.…”

The idea of a practical examination in a subject is an old and established one in many fields, within chemistry, in widely differing areas of academics, and in many on-the-job training scenarios. In a dedicated course on chemical safety, we have found that “the unsafe lab practical” makes for a thought-provoking and yet fun final examination. This paper discusses the steps in making and executing such a practical examination and points out where such an examination can be delivered.

“…Both the GCL-I and OCL-II courses typically conclude with a practical exam. − Different approaches were taken by each course to replace these exams because GCL-I uses a traditional points-based grading system, whereas OCL-II uses a specifications grading system. , However, the widespread social uprising that occurred in late May and early June of 2020 in response to the deaths of Ahmaud Arbery, Breonna Taylor, George Floyd, and others necessitated alterations to our plans. Many of our students were directly impacted by the widespread protests and media reporting.…”

The instruction of high enrollment general and organic chemistry laboratories at a large public 10 university always have curricular, administrative, and logistical challenges. Herein, we describe how we met these challenges in the transition to remote teaching during the COVID-19 pandemic. We discuss the reasoning behind our approach, the utilization of our existing web-based course content, the additions and alterations to our curriculum, replacement of experimental work with videos, the results of both student and TA surveys, and lessons learned for iterations of these courses in the near 15 future.
