1. Assessment of Group Work within the ICS Disciplines The role of peer and self assessment in the assessment of groupwork Mark Lejk School of Computing & Technology University of Sunderland

2. Assessment of Group Work within the ICS Disciplines Types of peer assessment adapted from Topping (1998) Type 1 peer assessment of work produced by an individual by another individual Type 2 peer assessment of work produced by an individual by a collection of other individuals Type 3 peer assessment of work produced by a group by a collection of other individuals Type 4 peer assessment of the contribution of an individual to a group activity by other members of the same group

3. Assessment of Group Work within the ICS Disciplines Peer assessment within groups Formative (qualitative) Summative: category-based holistic

4. Assessment of Group Work within the ICS Disciplines Differences between Type 4 and Types 1 to 3 Product or process Zero-sum games Category-based peer assessment Length of time Size of group

5. Assessment of Group Work within the ICS Disciplines Quantitative Studies (1) When peer assessment takes place within a group assignment, what differences occur in the final distribution of marks when the peer assessment is performed holistically and when it is broken down into categories? Lejk & Wyvill (2001a) Both methods increase correlation with individual grades Holistic assessment gives high proportion of equal distribution Holistic assessment gives higher proportion at the extremes Tendency to do the category-based method holistically!

6. Assessment of Group Work within the ICS Disciplines Quantitative Studies (2) When self-assessment is included with peer assessment in a group assignment, how does the self-assessment of an individual compare with the peer assessment of that same individual? Lejk & Wyvill (2001b) Better students tend to under-assess themselves Weaker students tend to over-assess themselves Removal of self-assessment increases the spread of marks

7. Assessment of Group Work within the ICS Disciplines Quantitative Studies (3) When peer assessment is used within a group assignment, what differences occur when the peer assessment is performed secretly and when it is agreed as a group? Lejk & Wyvill (2001b) Agreement between peers is less when done secretly Spread of marks higher when done secretly

8. Assessment of Group Work within the ICS Disciplines Qualitative Studies Students prefer holistic assessment Students find peer assessment difficult and open to abuse Students prefer to peer assess in secret Students find self-assessment even harder Students find quantitative assessment unhelpful

9. Assessment of Group Work within the ICS Disciplines Observations More use should be made of qualitative peer assessment Qualitative peer assessment benefits assessor and assessee Same applies to self-assessment Fits in with modern assessment ideas e.g. progress files Holistic summative assessment better than category-based Do not include self-assessment in summative assessment Fairer quantitative assessment done in secret Qualitative assessment done in the open
