  3. 3. Exam types Oral Skype, video conference, web meeting Digital exam may be stored and reviewed Home exam Submission in VLE/LMS or other solutions Similar solution for non-exam School exam Essay form or answering questions Multiple choice Programming, using other software (excel etc) Other exams, case based or practical
  4. 4. BYOD on campus
  5. 5. Power to the students Wireless networks Physical locations for exams vary: on campus, in sports facilites, conference halls «anywhere indoors with large surface» • Ad hoc networking: need to extend eduroam/Wifi coverage • Ensure reliable backend fiber from base stations to campus Restricting access • Pushing access restrictions at edges (virtual desktops, client firewalls) • Access restrictions at network layer – per exam Power supply Rough estimate: 75W/student (3000 students = 225 kW) Ad hoc power supply, need to rig fast
  6. 6. Taskforce: use of student PCs on digital school exams Mandate Find scaleable technical solutions for digital school exams ASAP Networking the local projects and people Discuss technical solutions for “school exams” • • • Technology for exam mode on student devices (PC, Mac, tablets) Virtual desktops, domain control, bootable USB sticks, lockdown browser Security and access restrictions Deliverables Checklist for digital exams Investigating maturity of technology solutions (with the help of Evry) Collating results from the local projects
  7. 7. Taskforce: digital school exams Revised mandate: Digital exams Practical large scale solutions (As Soon As Possible) Requirements for digital exams Collaboration with digital assessment commission Deliverables Best Current Practice for student BYOD on exams Best Current Practice for exam rooms (power, network, security) Best Current Practice for digital exam life cycle
  8. 8. When do we need digital exams? Now Working group on national level for local projects University projects: hundreds of students/day do digital exams College projects: tens of students/day do digital exams Sharing pain, sharing gain Based on project result, checklist Preparation before exam start Exam day • • Technical solutions Support solutions Tidying up after exam day and input to exam workflow
  9. 9. Check list before the exam day Managing student expectations Test exams Responsibilities: bring your own device (and power supply) Prepare student devices Controlling hardware and devices Software requirements Logging Support and organizational systems Usability IT support team available Test exam, organizational learning systems
  10. 10. Exam mode Configure equipment and environment in exam mode Students must release private devices to controlled exam mode Exam is a controlled exercise Audit is required of security system (holistic, not just ICT) Exam mode has max stressed out users: usability Exam mode Total control over the device: subject to university domain policy Virtual machine on the device: exam mode, with extra surveillance Lockdown browser: Test exams are important tools for IT, security and end user
  11. 11. Digital exam mode: alternatives Domain policy lockdown, not BYOD Virtual desktop (VDI) or terminal server Lockdown browser environment Virtual learning environment, exam mode Based on institution owned equipment Recommended in May be combined combination with with VDI or lockdown browser LMS/VLE Often used for term papers, lack some functionality Secure controlled environment on device Secure controlled environment on device Secure controlled environment on device Does not support extended security mode on device Easy to prepare various configurations Requires changes to existing licensing model and software install Requires software Low software installation requirements
  12. 12. Report: Large scale digital exams Study on available technical solutions for large scale digital exams Requirements gathered from Norwegian universities Thanks to NTNU, UiA and UiO Report (Myhre&Brede, Evry) April 2013 Yes, large scale VDI is possible today for digital exams • • Cloud server solution Clients available for PC, Mac (and tablets) Recommende further investigation of two solutions • • Microsoft Hyper-V with XenDesktop + Lockdown browser Inspera Assessment 2.0
  13. 13. Cheating on your exams Restricted use of sources Clear policies Post information about requirements and regulations Limit access Train exam proctors Monitor physical and network use Monitor PC activity, logging Restrict communications Monitor communications Restrict access Authentication: who was the student? Checking identity Surveillance and audit Plagiarism Automated checks for plagiarism Citation practices Restrict exam area Block line of sight Restrict network access to permissible sites on exam network Restrict access to exam network only Check for plagiarism
  14. 14. Cheating: the security view Paradox: students need access to (limited) information resource, but should not be able to communicate The Internet was built for communication, now we need to turn off the most useful features Monitor and audit Exam is controlled environment, audit documentation vital Users (students) are max stressed Ability to process input goes down significantly, may forget to bring PC or power or student ID Exams are time limited, and uptime must be 100% Storage and backup are vital, snapshots used to increase uptime We love proctors!
  15. 15. Handing in exam Document formats PDF for text documents (avoid Office files as end product) Possibility for other formats, for example • • Programming exams: program files Economics: spreadsheets Anonymization: stripping metadata in files Final version submitted: close exam mode Remember receipt for student (with copy of exam) Submitting as file across the network to storage
  16. 16. Checklist: Clear way exam mode Physical location: clear away power cables and network Remove network restrictions Remove logging Students (and their devices) must exit exam mode
  17. 17. Further work Investigate recommended VDI or terminal server solution lockdown browser mode solution VLE/LMS solution Formal requirements documents: Best Current Practice Prepare for one or more national procurements Prediction: More digital exams next semester We are running out of time
