E-Assessment with interactive images

摘要

Besides the fact that e-Assessment systems can efficiently conduct all paper based tests to evaluate knowledge and skills, they can offer a lot of new features via sophisticated information and communication technologies, including adaptive testing, immediate evaluation, etc. Most of the realised e-Assessment systems use pictures in the realisation of e-Testing, but the pictures are mainly used as supported media enhancement of the multiple choice questions. We introduce a brand new idea to use interactive images, where the user can navigate and zoom the picture and provide answers by clicking on an appropriate graphical object, mark a region, annotate, set an answer/comment on a given position, etc. The application domain of this innovation is huge, including e-Assessment for those sciences, where image analysis is essential, such as analysis of medical images, gathering map selective user's opinion etc. We have developed three new question types based on interactive images that offer these innovations. The impact is not just in enhancement of offered technology, but also on preventing various cheating methods, such as memorising, guessing, etc. These innovations can improve the assessment results, by a more correct evaluation and knowledge assessment.
