Context and rationale:
Traditional exams (e.g. write 2 unseen essays in 2 hours) are not popular with students, often described as irrelevant by pedagogues, and don’t reflect the realities of the working world. As a result, exams are being displaced across the HE sector by a variety of coursework based assessments, where students have several weeks or months to produce demonstrations of their competence. However, report production on deadlines of a few days is commonly required in a range of jobs, and requires particularly efficient research and synthesis skills. Since assessment drives learning for the majority of students, giving them an incentive to develop these skills and an opportunity to demonstrate them is in their best interests. Independently, we both addressed this situation by developing ‘take home exams’, with a 48 hour turn-around, for the final year modules Rivers and Environment (Lynda) and Quaternary Geoscience (Jane). We both wanted to encourage students to read widely and develop a sound understanding of a complex and evolving literature; being able to interpret and synthesise reports produced by specialists is an important skill for GEES graduates.
We have employed two different approaches: an essay and a report. Both had a length limit of 2000 words. For Lynda’s essay-based exam, students are given a choice of two broad questions that require them to draw on the module content and other resources, presenting evidence and critically evaluating paradigms in fluvial science. The format was chosen to complement the mid-semester, report-based assignment. For Jane’s report-based exam, students are presented with a selection of data from a simulated Quaternary section and tasked with producing a report which identifies and describes stratigraphy units, proposes an interpretation of the environment present when each formed, and assigns stratigraphic ages. The report format is familiar to students, through previous coursework reports on their own datasets from field and lab work, and the option to write a report on a different dataset for formative feedback was offered as preparation.
Effects on learning:
Some students told us that the take-home exam format changed the way they studied throughout the module; they focused on collecting and organising relevant resources across the subject rather than reading a small number of selected items in detail, since they had less scope for ‘question spotting’ and knew the assessment would require them to use a range of ideas from the module. This led naturally to them looking at more articles, as they sought to fill in gaps in their collections, and to creating their own ‘map’ of the subject matter as they worked out how to organise and label their notes, books, web links and electronic files for easy relocation during the 48 hour period. The quality and range of references cited was at least as good as in a normal coursework essay, where students have up to twelve weeks to write about a single topic.
Skills, employability and challenges:
Embedding employability and transferrable skills is increasingly important, and students want to be able to recognise that this is happening. The take home exam format seems to ‘make sense’ to students in both the academic content and employability contexts, and clearly addresses some of their anxieties around the artificial but ‘high stakes’ nature of exams (“In the real world I’d just look that up!” is a common complaint). The format requires students to draw on their knowledge from the module, and their skill in locating, understanding and synthesising information and key sources of literature. It does not rely on cramming knowledge for a 2 or 3-hour exam, but on students being able to use a range of resources efficiently to help them work through a problem. One student commented to me (Lynda) that they “… learned about lateral thinking, applying skills and knowledge in new and different ways”.
A few students over the years have not liked the approach. One of Lynda’s students observed that “… even if you were asked to write a report in 2 days in the workplace you would not be asked to read, research and cite academic papers …”. Of course, this is exactly what you could be asked to do, and reflects some naivety on the students’ part, but also a lack of clarity on ours. We have addressed this via pre-assessment review and preparation seminars.
- Give clear instructions. For example, students are often concerned that those students that are able/happy to ‘pull all night-ers’ would be at an advantage; Lynda emphasised that students should aim to work standard graduate working hours* (9 – 12 hrs/day) on the task.
- Timetabling the exam. Concerns about clashes with other assessment at the end of semester and during the exam period have to be clearly addressed. We were allowed to tell the students which week the exam would be in, then wait until all the other assessment deadlines were out to identify the specific 48 hour period, avoiding clashes.
- Alternate assessment arrangements. Since the take-home exam gives students control over their environment, it reduces the need for alternate arrangements. One challenge we both encountered was the issue of students who would, under normal exam circumstances, be entitled to additional time based on their personal learning needs; university protocol required that a 48-hour exam be treated the same as a 2 hour exam in this case, and students were given individual deadlines with the appropriate percentage of added time. Our experience is that most students submit within the 48-hour period even if they are entitled to extra time.
Overall, we find that this kind of assessment is popular with and makes sense to students, creates desirable learning behaviours, directly addresses employability concerns as an embedded part of the module rather than an add-on or a checklist, and is rewarding to mark, since we have both seen very high levels of performance as students rise to the challenge of the task. We strongly recommend it as part of the designer’s tool kit for GEES curricula, and would be happy to discuss our experience with any interested colleagues.
