Characteristics & Development of Rubrics as Tools of Assessment
A rubric can be considered as an assessment tool that indicates clearly achievement criteria across all the components of any kind of student work, from written to oral to visual. It can be used for marking assignments, class participation, or overall grades.
Brookhart defines rubric as,
“coherent set of criteria for students’ work that includes descriptions of levels of performance quality on the criteria.”Brookhart
Types of Rubrics
There are two types of rubrics:
It refers to single criteria rubrics that are one-dimensional in nature. These rubrics are used for assessing the overall achievement of the participants on an activity or item according to the predefined achievement levels. The descriptions of the performance are usually written in full sentences and paragraphs.
This type of rubrics refers to two-dimensional rubrics with columns representing levels of achievement and rows representing assessment criteria. It helps you in assessing the achievements of participants using a single rubric but based on multiple criteria. Different weights or value can be assigned to different criteria and overall achievement can be included by totaling the criteria. It is mostly written in a table form
Characteristics of Rubrics as Tools of Assessment
The characteristics of rubrics as tools of assessment are as follows:
It is used to represent the dimensions based on which the evaluation of the student’s activity or artifact occurs.
It consists of qualitative descriptions which helps in differentiating the performance of students for a given criterion across a continuum.
The scoring strategy involves the articulation of the process of converting the student performance’s qualitative evaluations related to reach criterion into an overall judgment.
Development of Rubrics as Tools of Assessment
The development of rubrics as a tools of assessment takes place in the following manner:
The skills and knowledge to evaluate which assignment has been designed must be assessed.
The observable criteria must represent those skills and knowledge.
The best way you can use to divide the criteria for distinct representation and meaningful levels of student performance must be determined.
Performance Level Descriptors
The observable characteristics which enable a teacher to differentiate between the performance level of students for each criterion must be determined.
Addressing all of these factors can help one in the development of rubrics as a tool of assessment effectively and efficiently. Stevens & Levi, 2005, state,
“As a grading tool, rubrics can address these and other issues related to assessment: they reduce grading time; they increase objectivity and reduce subjectivity; they convey timely feedback to students and they improve students’ ability to include required elements of an assignment.
