An eExam (e-exam) is a timed, supervised, summative assessment conducted using each candidate’s own computer running a standardised operating system. Such examinations have advantages over paper-based exams, and can include new multi-media, simulation and software test items which give higher validity in respect of professional work practice.[1]

Definition

eExams fall into the category of eAssessment, where students demonstrate academic achievement using computers. Within this broad spectrum, eExams form a distinct use of technology where a ‘bring your own device’ (BYOD) computer is started up (booted) from a USB flash drive. Because each computer is booted from a USB flash drive, every candidate uses the same full operating system and application programs, irrespective of those installed on the internal hard drive. eExams optionally include networking connections, but these are usually restricted or eliminated to prevent collusion. Unlike most online quiz tools, the eExam is not restricted to a web-page, but makes the whole candidate computer available for the assessment. eExams are seen as having potential for curriculum transformation by changing the nature of assessment to fully incorporate computer technology. Autosave is a common feature of eExams, with intervals from 10 seconds to every 2 minutes. Some emerging models have been released into the public domain, and others are proprietary commercial material (with costs).

Emerging models

  • eExam System: the first use of any eExam.[2] for the award of a degree was in November 2009 at the University of Tasmania.[3] It was subsequently adopted for university entrance examinations by the Tasmanian Qualifications Authority in 2011.[4] In 2016 the eExam system became the subject of a national project in Australian universities.[5] Security methods limit access to the eExam USB flash drive, prevent use of all communication channels, and require a unique desktop security image photograph for every sitting. The source code is available under open source GPL licences.
  • Digabi: the mission of the Digabi project is to transform all university entrance assessments in Finland to eExams by 2020.[6] The source code[7] is available under a GPLv3 license.
  • RU exam system: this uses a Linux-based bootable USB exam system for students' laptops at Reykjavik University[8]
  • Secure-Exam-Environment: from Alpen-Adria-Universität Klagenfurt uses Moodle on a Knoppix-flavoured Linux distribution[9]

Similar systems

Each of these similar systems offers a basic word processor and multiple choice question functionality outside a web-page.

  • Examsoft SofTest requires each candidate to install proprietary software on their own computer and use it before the exam to download an encrypted question paper. This is unlocked during the exam, revealing multiple choice and essay-style questions to which the candidate responds. After the fixed time period of the exam, candidates leave the venue and connect within a short time to an Examsoft web-site to upload the encrypted answerscript.
  • Exam4 This product is marketed as a secured word processing environment for high-stakes essay exams. Candidates install the software and respond to essay-style and/or multiple choice questions. The software can be set to block access to the internet and local hard drives. At the end of the exam, candidate responses are uploaded to a server for decryption and marking.
  • TCExam is a platform and language independent web-server based system. Candidates use conventional web-clients to connect to the local TCExam server and take the assessment online. It is an open source project using the AGPLv3 license.

Challenges

Many innovations face reactionary challenges in the social, political and technical spheres. Objections focus on the unreliability of computer equipment or the potential for cheating. Some ‘hacks’ against eExams use cooling of the computer RAM to 0 degrees Celsius, when the contents can be preserved for about 45 seconds.[10] This is irrelevant if the exam question paper is published after the assessment and open source software is used (since the material is put in the public domain anyway).[11] These criticisms have been answered by a risk tree comparison with paper-based examinations, finding the typing and handwriting in examinations are similarly secure[12]

Outcomes

Studies have indicated that candidates have a bi-modal response to eExams, with some loving them, others hating them. Benefits include the capacity to edit responses without trace and ease of text production through typing (20% more words in the same time, for instance). Candidate fears focus on worry the technology will fail and lose typed answers. Curriculum reform appears possible, but few published studies have illustrated this to any great degree.
