Peer marking on a group-based problem solving assessment

Assessment overview

Group-based problem solving is a continuously assessed component of the core year 3 undergraduate physics third year Comprehensives module 鈥 a module designed to augment and consolidate 天美传媒鈥 problem-solving abilities using material covered in the first two years of the core undergraduate degree. In group-based problem solving 天美传媒 work in teams of 25 to solve a complex problem. The assessment runs over an entire term, in which the 天美传媒 are expected to organise themselves, and, ultimately, present their findings in a half-hour seminar. Unlike most other assessments, their mark is not provided by the module lead, but rather, the entire assessment is peer-based, with the other teams grading each groups seminar. Each individual mark is then determined by peer-to-peer marking within a group, based on the overall grade of the group.

Design decisions

Rationale for the design

The initial motivation for a group-based project was to improve the core physics degree鈥檚 provision on training regarding collaborative skills of the 天美传媒. The idea of the group-based problem solving is to provide an assessment that is as close to the real world working environments as possible, where collaborative groupwork is the norm. Initiated during Curriculum Review, the project ran for the first time for the 2021-22 year 3 cohort. Assessment is entirely conducted by module lead guided peer marking, designed to reflect the environment of a professional scientific research group environment such as a research committee. 

Practicalities

Assessment and provision of feedback

There are two components to the marks given: peer assessment during term for individuals, and then a peer-provided mark given to the whole team based on their end-of-module presentation. The individual peer assessment is in two parts, with one part given in early in the module, providing individuals with an opportunity to reflect & improve, and the final part given at the end. Marks and feedback for all components are split into several categories (for example 鈥渁ttitude鈥 and 鈥減articipation鈥 are two of the components of the individual peer assessment) and all are sent to and collated by the module leads. Module leads use the peer marks to give a final grade following an elaborate (and also robust & transparent) algorithm.

Student鈥檚 perspective

The module component is relatively new, having been introduced as part of Curriculum Review. Students tend to view it as challenging while also having a strong and positive appreciation of the idea and philosophy behind the exercise. One of the greatest challenges for 天美传媒 is working in groups of 25, which occasionally leads to a disproportionate amount of time on internal group organisation. Some 天美传媒 became too concerned with the organisational aspects of the project, at the expense of devoting time & energy to contributing to the physics, which was handled by other members of their group. This aspect was苍鈥檛 as well appreciated as much by 天美传媒, and was something flagged as an unanticipated problem by the module lead, and there are measures in place to improve this for future years

Further observations

This assessment really offers the opportunity to make use of each and everyone鈥檚 individual strengths, whilst also permitting individuals to recognise what aspects of teamwork they thrive in, and which areas they might be able to improve on. The use of 100% peer assessment is something that is unusual for the department, and indeed the College, and while it is difficult to execute well, it is something well worth considering for other courses.
