Peer-Assessment

Peer-Assessment

students comment on and judge their colleagues’ work

Advantages

Helps students to become more autonomous, responsible, & involved

Encourages students to analyze critically work done by others, rather than simply seeing a mark

Helps clarify assessment criteria Gives students a wider range of feedback

Advantages

More closely parallels possible career situations where judgment is made by a group

Reduces the marking load of the instructor Several groups can be run at once as not all

groups require the presence of the instructor

Disadvantages

Students may lack the ability to evaluate each other Students may not take it seriously, allowing

friendships, entertainment value, etc., to influence their marking

Students may not like peer marking because of the possibility of being discriminated against, being misunderstood, etc.

Without instructor intervention, students may misinform each other

Research Findings

Student ratings of colleagues are both reliable & valid.

Orpen [1982] found no difference between lecturer and student ratings of assignments in terms of average ratings, variations in ratings, agreement in ratings, or relationship between ratings.

Research Findings

Arnold et al [1981] reported that peer ratings of medical students were internally consistent, unbiased, and valid.

Other studies suggest there is variation according to factors such as age of the student [Falchikow, 1986].

Outcomes

One of the desirable outcomes of education should be an increased ability in the learner to make independent judgments about their own and others’ work.

Peer- and self-assessment exercises are seen as a means by which these general skills can be developed & practiced.

Value

A peer rating format can encourage a greater sense of involvement & responsibility, establish a clearer framework & promote excellence, direct attention to skills and learning, and provide increased feedback [Weaver & Cotrell, 1986].

Value of Feedback

Feedback helps students to improve and prevents them from making the same mistakes again.

Feedback for these purposes needs to come early in the course.

Value

Keeping the students focusing on improvement rather than judgment alone is crucial for personal development.  Students need constructive feedback to help them assess and then build on their own strengths.  They need to identify ways of addressing weaknesses and plan appropriate action.  The key benefit of peer assessment is the opportunity it provides for students to provide each other with multiple perspectives and lateral constructive suggestions.

High Quality Feedback

For students, high quality feedback consists of the following three things: Clear criteria against which to judge the

comments. Comments that are detailed and related to specific

aspects of their work. Comments that are improvement focused.

Value of Peer-Assessment

giving a sense of ownership of the assessment process, improving motivation

encouraging students to take responsibility for their own learning, developing them as autonomous learners

treating assessment as part of learning, so that mistakes are opportunities rather than failures

Value of Peer-Assessment

practising the transferable skills needed for life-long learning, especially evaluation skills

using external evaluation to provide a model for internal self-assessment of a student's own learning (metacognition), and

encouraging deep rather than surface learning.

Value

Student assessment of other students' work, both formative and summative, has many potential benefits to learning for the assessor and the assessed. It encourages student autonomy and higher order thinking skills. Its weaknesses can be avoided with anonymity, multiple assessors, and tutor moderation. With large numbers of students the management of peer assessment can be assisted by Internet technology.

Want Assessment Systems that: concentrate on what is learned rather than what is

taught, with a student-centred rather than a tutor-centered focus.

let students in on the process, by allowing them all know the rules of the game, particularly by the use of transparent, available and meaningful criteria, instead of making them play the "guess what's in teacher's mind" game.

Want Assessment Systems that: are fit for purpose, relating closely to the specified

learning outcomes and assessing the right things, not what is easy to assess.

promote lifelong learning, by helping students to evaluate their own and their peers’ achievements realistically, not just encouraging them always to rely on (tutor) evaluation from on high.

encourage divergent outcomes rather than convergent ones, so the students have the opportunity to demonstrate their individuality rather than striving towards a single, correct answer.
