Assessment Elements
In order to assess an answer submitted to a
challenge a number of "Assessment Elements" will be defined,
covering each one a particular aspect to be assessed in the answers
submitted and depending its number on the size and complexity of the
challenge. The elements will have the following characteristics:
- DESCRIPTION of the assessment element. It should clearly
determine which aspect of the task is being assessed. In the case of
a qualitative assessment, it will be useful to provide details of
what is considered excellent, average, etc.
- SCALE of the assessment element. There are several
predetermined scales, from the simple YES/NO scale, to a scale of
total percentage. Each assessment element will use its own scale,
which must be choosen so that it can adjust to each possible
variation of the element. However, it must be taken into account that
the scale does not determine how important an assessment element is
when the final score is calculated: for example, an element with a
2-point scale will have the same "influence" in the final
score than another element that uses a 100-point scale, whenever the
respective elements has the same weight or ponderation factor.
- WEIGHT of the assessment element. By default, each element
has the same importance when the final score of the task is
calculated. However, this fact can be changed by giving the more
important elements a weight higher than one, and to the less
important elements a weight lower than one. It must be also taken
into account that to modify the weight does NOT affect the possible
maximum score of a submitted answer, because this value is determined
by the Highest
Score parameter set for the challenge to which the answer is being
submitted and the time when it was submitted.
The system allows to customise the set of
assessment elements defined for each challenge added to a
QUESTOURnament.
