1. ‘At the Coal Face’ Experiences of Computer-based Exams John Winkley, BTL Paul Humphries, Edexcel Dorit Reppert, CCEA July 8 th 2003

2. Evaluating Computer-based Exams Key Stakeholders: candidates test centres examiners Awarding Bodies Key Stakeholders: candidates test centres examiners Awarding Bodies Key Success Factors: engagement accessibility technical usability system reliability security test validity, reliability data analysis Key Success Factors: engagement accessibility technical usability system reliability security test validity, reliability data analysis

13. The Test Centre Experience Priority 1 – a reliable technical infrastructure:  includes trained support staff  unreliability may interrupt an exam  funding, management processes are key factors Priority 1 – a reliable technical infrastructure:  includes trained support staff  unreliability may interrupt an exam  funding, management processes are key factors Priority 2 – an appropriate exam environment:  setting-up takes longer  can be difficult to provide adequate privacy Priority 2 – an appropriate exam environment:  setting-up takes longer  can be difficult to provide adequate privacy

14. The Test Centre Experience Schools:  computer-based exams entirely new to schools  transfer of responsibility from administrators to technical staff  48% found software installation easy or very easy  54% had no problems with candidate registration  all schools ran exams successfully Schools:  computer-based exams entirely new to schools  transfer of responsibility from administrators to technical staff  48% found software installation easy or very easy  54% had no problems with candidate registration  all schools ran exams successfully

15. The Test Centre Experience learndirect centres :  technical infrastructure already exists for e- learning and formative assessment  used to maintaining ‘business critical’ IT systems  95% of 29 Skills for Life project centres found the installation easy or very easy  all centres found registration of candidates using MicroBoard easy learndirect centres :  technical infrastructure already exists for e- learning and formative assessment  used to maintaining ‘business critical’ IT systems  95% of 29 Skills for Life project centres found the installation easy or very easy  all centres found registration of candidates using MicroBoard easy

16. The Candidate Experience School Pupils:  ‘digital natives’  at ease with IT  over 94% use a computer at  home at least once a week  exams are mandatory School Pupils:  ‘digital natives’  at ease with IT  over 94% use a computer at  home at least once a week  exams are mandatory Adult Learners:  great disparity of IT experience  some with no IT experience  have opted for National Tests Adult Learners:  great disparity of IT experience  some with no IT experience  have opted for National Tests

17. The Candidate Experience School Pupils:  Overwhelmingly positive  92% said they enjoyed the tests School Pupils:  Overwhelmingly positive  92% said they enjoyed the tests Adult Learners:  computer-based exams seen as new and positive  “almost unanimously they reported preferring to take an online test rather than a paper test” - Ufi Adult Learners:  computer-based exams seen as new and positive  “almost unanimously they reported preferring to take an online test rather than a paper test” - Ufi “It didn’t feel like an exam” “more enjoyable than writing”

18. The Candidate Experience Common concerns:  technology failures: rare but disconcerting mainly due to PC system problems candidates can continue on a spare PC without losing work  the exam environment keyboard noise in particular Common concerns:  technology failures: rare but disconcerting mainly due to PC system problems candidates can continue on a spare PC without losing work  the exam environment keyboard noise in particular

20. The Examiner Experience General responses:  9 out of the 10 examiners found the marking either very enjoyable or enjoyable  all found the software either very easy or easy to use  most would prefer to work at home  liked choice of being able to mark ‘by candidate’, ‘by question’ or both General responses:  9 out of the 10 examiners found the marking either very enjoyable or enjoyable  all found the software either very easy or easy to use  most would prefer to work at home  liked choice of being able to mark ‘by candidate’, ‘by question’ or both

21. Potential for more rapid marking :  marking speed increased with experience  marking ‘by question’ increases efficiency Potential for more rapid marking :  marking speed increased with experience  marking ‘by question’ increases efficiency The Examiner Experience More accurate tallying:  automatic tallying of marks  error-prone task removed More accurate tallying:  automatic tallying of marks  error-prone task removed

22. The Awarding Body Experience Engaging learners:  closer to day-to-day experiences for many  exam stress reduced  positive impact on self-esteem  more engaging than paper-based exams Engaging learners:  closer to day-to-day experiences for many  exam stress reduced  positive impact on self-esteem  more engaging than paper-based exams

23. Accessibility:  Much greater flexibility: can register candidates up to the exam start ‘on demand testing’ will be possible  ‘on screen’ approach allows tests to be taken: in mobile situations (e.g. touring bus) in remote locations (e.g. using laptops) Accessibility:  Much greater flexibility: can register candidates up to the exam start ‘on demand testing’ will be possible  ‘on screen’ approach allows tests to be taken: in mobile situations (e.g. touring bus) in remote locations (e.g. using laptops) The Awarding Body Experience

24. Quality assurance:  Less opportunity for human error  Quality checks have to be refocused Quality assurance:  Less opportunity for human error  Quality checks have to be refocused Security:  less vulnerable to lost or mishandled papers  encryption technologies increase security Security:  less vulnerable to lost or mishandled papers  encryption technologies increase security

25. The Awarding Body Experience Exam reliability:  100% reliability for ‘closed’ question types  ‘open’ question types: marking remains subjective MarkerBase helps examiners to be more consistent Exam reliability:  100% reliability for ‘closed’ question types  ‘open’ question types: marking remains subjective MarkerBase helps examiners to be more consistent

26. The Awarding Body Experience Exam validity:  Good correlation with paper-based National Tests  GCSEs, using wider range of question types, will require additional validation effort Exam validity:  Good correlation with paper-based National Tests  GCSEs, using wider range of question types, will require additional validation effort

27. The Awarding Body Experience Results generation:  possibility of more rapid feedback to candidates  provide results to test centre rather than to candidates Results generation:  possibility of more rapid feedback to candidates  provide results to test centre rather than to candidates Data analysis:  richer feedback to candidates and test centres  easier to detect anomalies in candidate responses Data analysis:  richer feedback to candidates and test centres  easier to detect anomalies in candidate responses

28. Conclusions  very popular with candidates - more engaging and interactive, but additional validation needed  greater security and reduced risk of human error  improved accessibility and flexibility – highly desirable for Awarding Bodies  quality of technical infrastructure is vital  may initially place a burden on test centres, but with the promise of efficiency gains over time  very popular with candidates - more engaging and interactive, but additional validation needed  greater security and reduced risk of human error  improved accessibility and flexibility – highly desirable for Awarding Bodies  quality of technical infrastructure is vital  may initially place a burden on test centres, but with the promise of efficiency gains over time
