CAA in UK HE: The State of the Art Bill Warburton University of Southampton Email: wiw@soton.ac.uk Research & Graduate School of Education
The 2003 survey • Introduction • Demography • Findings: • Question banks • CAA software • Pros & Cons • Question types • VLEs & MLEs • Interoperability • Summary Research & Graduate School of Education
The 2003 survey • Why do a CAA survey now? • Increasing prevalence of web-based delivery • Pervasiveness of Virtual Learning Environments (VLEs) • Emergence of Managed Learning Environments (MLEs) • Emergence of Interoperability standards e.g. IMS/QTI • Four year gap e.g. between 1999 & 1995 CAA surveys Research & Graduate School of Education
The 2003 survey • Similarities with the (1999) CAA Centre Survey* • For congruence, a superset of the 1999 survey • Dissimilarities with 1999 survey • Extra questions on VLEs, MLEs & Interoperability • Targeted CAA enthusiasts rather than non-users • Delivered purely by web-based CAA system Research & Graduate School of Education *Bull, 1999; Bull & McKenna, 2000; Bull & Hesketh, 2001
The 2003 survey: Who were the respondents? • Targeted people who were likely to be using CAA • Incentive- prize draw of two £25 book tokens • Survey questionnaire was distributed using three JISC mailbase lists: • CAA • TOIA • ALT • 50 responses received by initial deadline of 18th May • Will be issued more widely Research & Graduate School of Education
The 2003 survey: Who were the respondents? • CAA Involvement: • A constituency of enthusiasts Research & Graduate School of Education
The 2003 survey:Job Function • Little more than half the 2003 respondents were academics (1999: 77% were academics) • An increased proportion of pedagogic & ICT support Research & Graduate School of Education
The 2003 Survey: Who supports CAA now? • CAA support is largely centralised • Even where support has been devolved to faculties / departments, there is usually a central CAA service Research & Graduate School of Education
The 2003 survey: Who uses CAA now? Usage by Subject : broadly the same as 1999 Research & Graduate School of Education
2003 Survey: The use of question banks • Nearly 60% said they now use question banks • Nearly 90% would be interested in sharing questions Research & Graduate School of Education
The use of question banks • Pros of question sharing- shared loads: • Authoring • QA • Editing • Cons of question sharing: • Initial time penalty • difficulty of applying rigorous QA standards across multiple authors & institutions • requirement for multiple formats to suit all users Research & Graduate School of Education
The use of question banks • Example in Science: • The e3an project developed an item bank of more than 1500 questions for use in Electronics and Computer Science • Example in Humanities: • A question bank has been developed to pre-course assess modern language students Research & Graduate School of Education
2003 Survey: What CAA software is used in HE now? • Commercial CAA systems are more dominant • Many respondents used multiple CAA systems
2003 Survey: What CAA software is used in HE now? • Split between users of Commercial and Open systems • Commercial systems- traditionally seen as expensive but easier to use • Non-commercial systems e.g. TRIADS- free, but support-intensive Research & Graduate School of Education
2003 Survey: Advantages of different CAA software Research & Graduate School of Education
2003 Survey:Disadvantages of different CAA software Research & Graduate School of Education
2003 Survey: Main benefits of CAA • Little different from 1999, considering small sample • 1999 survey: • Speed of feedback to students • Statistical analysis of results • Automatic marking • 2003 survey • Speed of feedback: “Available 24/7 - with instant feedback” • Speed of automatic marking: “50 pieces of coursework marked in a flash” • Formative use promotes student learning: “students often retake quizzes and improve their score”
2003 Survey: Main disadvantages of CAA • There appears to have been a shift- Learning curve and up-front investment are now seen to be the most prominent disadvantages • 1999 survey: • access to and reliability of hardware and software • amount of time needed create and organize delivery • difficulty of writing good questions • 2003 survey: • amount of time needed create and organize delivery • access to and reliability of hardware and software • difficulty of writing good questions Research & Graduate School of Education
2003 Survey: Does CAA save time? • The 2003 respondents were evenly split regarding the time saved by CAA Research & Graduate School of Education
2003 Survey: Does CAA save time? • Surprisingly, a large majority of those who reported productivity benefits did not see a corresponding shift in workload to other staff Research & Graduate School of Education
2003 Survey:Formative vs. Summative testing • There appears to be a definite shift towards formative use: less than half the 2003 tests were summative (1999: most tests were summative) • Diagnostic use is emergent: other formative usage is long-established Research & Graduate School of Education
2003 Survey:Question types • 1999: MCQ & MRQ most popular followed by text and numeric input, then graphic hot spot and other types • Little appears to have changed in 2003: MCQ still top Research & Graduate School of Education
2003 Survey: Who is doing CAA? • Moore's Gap has yet to be crossed: CAA appears still to be largely the province of ‘early adopters’ • Will CAA follow VLEs and become mainstream technology? Research & Graduate School of Education
2003 Survey:The growth, influence and relevance of VLEs • Have VLEs crossed Moore’s Gap? Are now pervasive • Most respondents (81%) had implemented site-wide VLEs • It seems that VLE quiz tools give users a taste for CAA • The uptake of VLEs may foreshadow the uptake of CAA Research & Graduate School of Education
2003 Survey:The growth, influence and relevance of VLEs • VLEs are seen as a largely positive (60%) influence on the uptake of CAA • Cautionary note: Two reports that VLEs apparently discouraged the use of CAA Research & Graduate School of Education
2003 Survey:Interoperability & VLEs • The majority of VLE quiz users wanted to export their quizzes to a dedicated CAA system • One respondent wanted to import CAA items and tests into a VLE Research & Graduate School of Education
2003 Survey:tension between VLE quizzes and CAA • Many respondents attempting to do CAA using VLE’s Quiz engine • Most commented unfavourably on VLE Quiz engines: “…testing facility is very limited, but is all we have available” • Cultural & technical differences between VLEs & CAA: • Words do not always have common meanings- • Blackboard refers to a quiz as an ‘item’ • In CAA an ‘item’ is usually a single question • VLE quiz items/tests often restricted to proprietary formats, & may be less secure Research & Graduate School of Education
2003 Survey:The emergence of MLEs • More than two thirds of respondents’ institutions have stated an intention to develop an MLE • However, the concept of an MLE is contended (JISC 7/99 projects) Research & Graduate School of Education
2003 Survey:Interoperability • The majority of HE users thought interoperability to be important Research & Graduate School of Education
2003 Survey:Interoperability • Although most HE users thought interoperability to be important, awareness of interoperability standards varied widely Research & Graduate School of Education
Summary • Superset of 1999 survey + extra questions on VLEs, MLEs & Interoperability • Demography: More support staff involved than in 1999 • Question banks: Desirable but rare • CAA software: Commercial CAA systems dominant but inflexible • Pros: Little changed from 1999- time savings • Cons: Learning curve now more significant than cost • Question types: MCQs & MRQs still predominant • VLEs: have crossed Moore’s Gap and appear to drive CAA • MLEs: Most HEIs intend to implements MLEs (but concept of MLE contended) • Interoperability: thought to be important, but awareness of standards varies Research & Graduate School of Education
End of presentation • Questions? • Question banks: desirable but how much effort? • CAA software: What features do people most want? • Pros & Cons: at what point do the pros outweigh the cons? • What question types do people most use? Most want? • What roles do Interoperability, VLEs & MLEs play in promoting CAA? • Do Interoperability, VLEs & MLEs drive CAA or vice-versa? • When will CAA cross Moore’s Gap?
