Student assessment: lightening the load while increasing the learning Dr Chris Rust Head, Oxford Centre for Staff and Learning Development Deputy Director, Assessment Standards Knowledge Exchange (ASKe) Centre for Excellence in Teaching and Learning Oxford Brookes University, UK
3 possible ways of reducing staff assessment load • Involve the students • Mechanise • Strategic programme decisions
Self-assessment Strengths of this piece of work Weaknesses in this piece of work How this work could be improved The grade it deserves is….. What I would like your comments on
Marking exercise Immediate results participants av. mk non participants av. mk. Cohort 1 (99/00) 59.78 54.12 Cohort 2 (00/01) 59.86 52.86 Cohort 3 (01/02 55.7 49.7 Results 1 year later Cohort 1 57.91 51.3 Cohort 2 56.4 51.7 Rust, C., Price, M & O’Donovan, B.(2003) "Improving students’ learning by developing their understanding of assessment criteria and processes” Assessment and Evaluation in Higher Education, Vol. 28, No. 2
Peer marking using model answers (Forbes & Spence, 1991) Scenario: • Engineering students had weekly maths problem sheets marked and problem classes • Increased student numbers meant marking impossible and problem classes big enough to hide in • Students stopped doing problems • Exam marks declined (Average 55%>45%) Solution: • Course requirement to complete 50 problem sheets • Peer assessed at six lecture sessions but marks do not count • Exams and teaching unchanged Outcome: Exam marks increased (Av. 45%>80%)
Peer feedback (Rust, 2001) Scenario • Geography students did two essays but no apparent improvement from one to the other despite lots of tutor time writing feedback • Increased student numbers made tutor workload impossible Solution: • Only one essay but first draft required part way through course • Students read and give each other feedback on their draft essays • Students rewrite the essay in the light of the feedback • In addition to the final draft, students also submit a summary of how the 2nd draft has been altered from the1st in the light of the feedback Outcome: Much better essays
Mechanise assessment • Statement banks • Assignment attachment sheets • Optical mark reader • Computer aided-assessment
Mechanise assessment - 1 Statement Banks Write out frequently used feedback comments, for example: • I like this sentence/section because it is clear and concise • I found this paragraph/section/essay well organised and easy to follow • I am afraid I am lost. This paragraph/section is unclear and leaves me confused as to what you mean • I would understand and be more convinced if you gave an example/quote/statistic to support this • It would really help if you presented this data in a table • This is an important point and you make it well etc…….
Weekly CAA testing - case study data (Brown, Rust & Gibbs,1994)
CAA quizzes (Catley, 2005) Scenario • First term, first year compulsory law module • A new subject for most (75%) students • High failure rate (25%), poor general results (28% 3rd class, 7% Ist) Solution: • Weekly optional WebCT quizzes (50% take-up) Outcome: Quiz takers: 4% fail, 14% 3rd class, 24% Ist Non-quiz takers: same pattern as before Overall: 14% fail (approx half previous figure) 21% 3rd class 14% 1st (double previous figure)
Strategic reduction 1 Need audits: - Of assessment methods - Of learning outcomes Need Departmental learning, teaching and assessment strategies
Strategic reduction 2 Reduce time spent on assessment: • reduce repetition (eg lab reports) • more variety (eg less essays) • identify different course goals • ? pass/fail (at least in 1st year) • just grades, no marks • assess selectively
Assessing a selection (Rust, 2001) Scenario: • Weekly lab reports submitted for marking • Increased student numbers meant heavy staff workload and increasingly lengthy gap before returned so feedback of limited/no use Solution: • Weekly lab reports still submitted • Sample number looked at, and generic feedback e-mailed to all students within 48 hours • At end of semester, only three weeks’ lab reports selected for summative marking Outcome: • Better lab reports and significantly less marking
Strategic reduction 3 Reduce time spent on feedback: • give general feedback / whole class • use feedback forms • use students • use statement banks • use computer-based tests • give focused feedback (one criterion) • give audio-recorded feedback
