Rubric (academic)
From Wikipedia, the free encyclopedia
A rubric is a marking system used by teachers, consisting of a chart of criteria for evaluation of students' work.
It allows for standardised evaluation according to specified criteria, making grading simpler and more transparent.
[edit] Technical
One problem with rubrics is that each level of fulfillment encompasses a wide range of marks. For example, if two students both receive a 'level four' mark on the Ontario system, one might receive an 80% while the other receives 100%.
In addition, a small change in rubric evaluation caused by a small mistake may lead to an unnecessarily large change in numerical grade. Both of these problems may be addressed by the use of finer gradations in rubric evaluations.
Rubrics may also make marking schemes more complicated for students. Firstly, showing one mark may be inaccurate, as receiving perfect in one section may not amount to be very significant in the long run if that specific strand is not weighted heavily. Some may also find it difficult to comprehend an assignment having four distinct marks, which may make it unsuitable for some younger children. Nonetheless, it allows for students to compensate a lack of ability in one strand by improving another one. Ergo, if a student has difficulty communicating his/her ideas, they may still be able to attain a relatively high mark, as communication is typically not weighted heavily. Rubrics may also allow students to better their weaknesses.
[edit] Usage
The Ontario rubric is an example of a rubric which has become fairly popular in the school system.
