This research investigates the feasibility and usefulness of designing an authoring environment for diagram-based Computer Based Assessment (CBA). CBA systems present students with an environment that permits them to solve exercises. Upon completion, solutions to the exercises are marked automatically, and the results, along with instructional feedback, are returned to the students. CBA exercises are authored by educators who gain practical and pedagogic benefits from automating the assessment of their students. Until now, facilities to develop CBA have only been implemented for exercises where the answers are text-based. The deliverables described in this dissertation implement novel solutions to problems in three areas. The first area concerns the customisation of graphic editors to the learning material. The proposed solution is an object-oriented framework for visually specifying and authoring diagram editors. The second area presents techniques for describing the marking criter...

This document ,reports on the ,results of re-designing and re-implementing the Ceilidh courseware system. It highlights the limitations identified in the thirteen years of Ceilidh’s use at the University of Nottingham. It also illustrates how most of these limitations have been resolved by re-designing Ceilidh’s architecture and improving various aspects of the marking and administrating processes. The new system,

Programming computers is becoming an increasingly popular activity, not only for computer science students but across a large number of other disciplines. But funding and other resources for teaching programming have not, for the most part, kept pace with the continuous growth in the ...

While teaching in all its forms can sometimes be fun, for most people marking student work is tedious, boring and in general hard work. A courseware system is presented that not only provides on-line support for courses, but importantly can automatically assess student work.

While teaching in all its forms can sometimes be fun, for most people marking student work is tedious, boring and in general hard work. A courseware system is presented that not only provides on-line support for courses, but importantly can automatically assess student work. CourseMaster can mark several types of coursework in a non-trivial manner. That is, criteria can be

CourseMaster (CM) is a Computer Based Assessment (CBA) system. This paper describes the motivation and aims for developing CM's Marking System. It also explains the architectural forces and design decisions that have been established in order to engineer the Marking System. The Marking System adheres to the rigid specifications of the initial CM's design, which are: reliability, coherency, security, feedbackrichness, extensibility and customisability. The above notions and the features that CM's Marking System provides are examined in detail. Concrete implementation issues are also discussed with conclusions on usability and extensibility observations.
