ABSTRACT
There are many different facets to flexibility puter-aided assessment, depending on one’s viewpoint. As an example, for the developer increasing the flexibility of an assessment product means increasing the development cost but also increasing the size of the potential market. For the examiner, flexibility means the ability to use assessment aids in the specific way and for the specific purpose which he/she requires. For the candidate, flexibility means being given a range of ways to answer a set of questions so that he/she can demonstrate his/her knowledge/skill to the best effect.
The higher the level of knowledge/skill to be assessed, the more difficult the assessment, the more flexible the assessor needs to be and the greater the involvement of human assessors in the assessment process. For simple types of assessment, for example, the use of multiple-choice questions, the assessment process can be pletely automated and little human examiner involvement is required. For plex assessment, for example, assessment of a design rather than an implementation, the candidate has many more options available and the assessment is not simply in terms of true or false but rather in degrees of correctness. At such puter software acts as an aid or filter to the human examiner, marking some attempts but passing attempts which are difficult to assess to the human examiner. The optimum balance, in terms of cost-effectiveness, between automatic assessment and the use of human examiners varies with time and is very sensitive to the number of candidates to be assessed.
Most of the puterised assessors assess e rather than method since this is easier to automate. Techniques are now being developed which allow the method used to generate the answer to be collected and assessed. This will
