The process by which students learn to program is a major issue in computer science educational research. Programming is a fundamental part of the computer science curriculum, but one which is often problematic. It seems to be difficult to find an effective method of teaching that is suitable for all students. In this research we tried to gain insights into(More)
This article reports on the design, implementation, and usage of the CourseMarker (formerly known as CourseMaster) courseware Computer Based Assessment (CBA) system at the University of Nottingham. Students use CourseMarker to solve (programming) exercises and to submit their solutions. CourseMarker returns immediate results and feedback to the students.(More)
In this paper we present a new database for off-line Arabic handwriting recognition, together with several preprocessing procedures. We designed, collected and stored a database of Arabic handwriting (AHDB). This resulted in a unique databases dealing with handwritten information from Arabic text, both in terms of the size of the database as well as the(More)
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(More)
Hidden Markov Models (HMM) have been used with some success in recognizing printed Arabic words. In this paper, a complete scheme for totally unconstrained Arabic handwritten word recognition based on a Model discriminant HMM is presented. A complete system able to classify Arabic-Handwritten words of one hundred different writers is proposed and discussed.(More)
Purpose – The purpose of this paper is to document organizations’ self descriptions of why they initiated sustainable development (SD) reporting and explore these explanations using an institutional theory framework. Design/methodology/approach – Constructs organizational narratives from semi-structured in-depth interviews with reporting champions who(More)
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,(More)
