Assessment Delivery Engine for QTIv2 Tests.
No full textThe IMS Question and Test Interoperability (QTI) standard has not had a great take-up in part due to the lack of tools. This paper describes the ‘ASDEL’ test delivery engine, focusing upon its architecture, its relation to the item authoring and item banking services, and the integration of the R2Q2 Web service. The project first developed a java library to implement the system. This will allow other developers and researchers to build their own system or take aspects of QTI they want to implement
Learning objects and learning designs: an integrated system for reusable, adaptive and shareable learning content
No full textThis paper proposes a system, the Smart Learning Design Framework, designed to support the development of pedagogically sound learning material within an integrated, platform-independent data structure. The system supports sharing, reuse and adaptation of learning material via a metadata-driven philosophy that enables the technicalities of the system to be imperceptible to the author and consumer. The system proposes the use of pedagogically focused metadata to support and guide the author and to adapt and deliver the content to the targeted consumer. A prototype of the proposed system, which provides proof of concept for the novel processes involved, has been developed. The paper describes the Smart Learning Design Framework and places it within the context of alternative learning object models and frameworks to highlight similarities, differences and advantages of the proposed system
Giving You back Control of Your Data: Digital Signing Practical Issues and the eCert Solution
No full textAs technologies develop rapidly, digital signing is commonly used in eDocument security. However, unaddressed issues exist. An eCertificate system represents the problem situation, and therefore is being used as case study, in a project called eCert, to research for the solution. This paper addresses these issues, explores the gap between current tools and the desired system, through analysis of the existing services and eCertificate use cases, and the identified requirements, thereby presenting an approach which solves the above problems. Preliminary results indicate that the recommendation from this research meets the design requirements, and could form the foundation of future study of solving digital signing issues
Towards a framework of a secure e-qualification certificate system
No full textwe all receive paper based certificates during our study journey, but they are hard to manage to avoid damage or loss. The field of e-Learning provides technological developments, such as e-portfolios, which enable greater power and flexibility in displaying achievements. These may include on-line versions of certificates of the applicant's attainment which overcome the limitations of paper-based versions. However, these “e-certificates” present a number of practical challenges, which so far have not been addressed, such as the validation of claimed e-qualification certificates. This paper addresses the issues, and explores the gap between current e-portfolio tools and the desired e-qualification certificate system. Through analysis of the existing systems and e-certificate use cases, we have identified existing services that can be reused and the services that require further development, thereby presenting an approach which solves the above problems. Preliminary results indicate that the recommendation from this research meets the design requirements, and could form the foundation of future e-certificate implementations
Immortal and Ageless: Artemis in a Fresco from Akrotiri, Thera
No full textThis abstract of a paper sketches out an interpretation of the goddess in the women-oriented wall paintings from Xeste 3, Akrotiri, Thera (ca. 1600 BCE). The author proposes that she is Artemis
Saffron Crocus and Yellow Garments in Aegean Wall-Painting
No full textThis paper was prepared for the conference, Colour in the Ancient Mediterranean World, Edinburgh, 9-11 September 2001. The author revised the paper and published it in the volume dedicated to Sara Immerwahr (online at this site). The study looks at saffron-dyed costumes, with a focus on their appearance in Aegean art
A delivery engine for QTI assessments
No full textThe IMS Question and Test Interoperability (QTI) standard has had a restricted take-up, in part due to the lack of tools. This paper describes the ‘ASDEL’ test delivery engine, focusing upon its architecture, its relation to item authoring and item banking services, and the integration of the R2Q2 web service. The tools developed operate with a web client, as a plug-in to Moodle, or as a desktop application. The paper also reports on the load testing of the internal services and concludes that these are best represented as components. The project first developed a Java library to implement the system. This will allow other developers and researchers to build their own system or incorporate aspects of QTI they want to implemen
(Semantic Web) Services for e-Learning
No full textService-Oriented Architectures are becoming a popular system paradigm in e-learning, and there are several efforts to create community driven service frameworks. In this paper, we argue that these efforts could benefit if they also drew on Semantic Web technologies to create (Semantic Web) Services – services that use resources described on the semantic web. We present a demonstrator which uses three such services to search over question bank data. We show how the use of Semantic Web technologies not only promotes high-quality and interoperable metadata, but that it also enables reasoning rules to be declared that make developing new services easier
Mapping the e-Learning Assessment Domain: Concept Maps for Orientation and Navigation
No full textConcept or Topic Maps have long been used as a method of categorizing and organizing information about a domain. Building them can help people conceptualize an area and spot trends or gaps, and as a presentation method they quickly provide an overview and general impression of a space. We are currently constructing a Reference Model of the Assessment Domain that takes the form of a highly interlinked dynamic website. This represents the assessment domain via the software, projects, standards and use cases of which it is composed. In this paper we present our efforts to create complimentary concept maps of the assessment domain, not as an overview, but for navigation and orientation within the domain. These concept maps, which model resources and activities independently, have been corroborated with practitioners in the e-learning community
