Abstract [sv]

Denna artikel beskriver den iterativa utvecklingsprocessen av lärobjektsförrådet eNOSHA. Diskussionerna om ett lärobjektsförråd startade under 2007 vid University of Colombo, School of Computing (UCSC) av personalen i universitetets e-lärandecentrum. Under det senaste decenniet har det i e-lärandecentrumets dagliga arbete utvecklats mängder av digitalt undervisningsmaterial för det treåriga kandidatprogrammet eBIT som ges nationellt på distans över Sri Lanka. Efter en inledande analys av behoven av att lagra lärobjekt vid UCSC samt en utvärdering av tillgängliga öppna lärobjektsförråd togs ett beslut att starta utvecklingen av eNOSHA. Inget av de utvärderade existerande lärobjektsförråden klarade den uppställda kravspecifikationen samtidigt som det fanns ett skriande behov av att lagra och dela kursmaterial. Systemet är designat med huvudmålet att stödja lagring, sökning och och återanvändning av lärmaterial på ett användarvänligt sätt som kan främja den framtida vidare utvecklingen av lärmaterial vid UCSC.Vi fann det också av vikt att sträva efter en flexibel design som kan hantera olika sorters lärobjekt inom olika organisationer i olika delar av världen. Utvecklingsprocessen startades genom en fokusgrupp bestående av personal från UCSCs e-lärandecentrum och externa svenska medlemmar från ett svensk – sri lankesiskt biståndsprojekt. Utifrån den genomförda behovsanalysen togs en kravspecifikation och en preliminär utvecklingsplan fram i december 2008. Som övergripande utvecklingsmetod i projektet har kooperativ design använts och att presumtiva användare vid UCSC har varit involverade i systemutvecklingens olika faser. Testning och kodgranskning har genomförts inkrementellt och iterativt vid tre olika universitet i Sri Lanka, Finland och Sverige enligt de principer som finns fastställda inom Designvetenskap/Design Science. Vårt mål med det valda angreppssättet är att utveckla ett system som ska vara mer flexibelt och mer generellt än att enbart leva upp till de ställda kraven vid UCSC i Sri Lanka. Resultaten av de genomförda testerna visar att eNOSHA lever upp till de ställda kraven när det gäller stöd för återanvändning och sökfunktionalitetet, men att modulen för uppladdning med dess tillhörande krav på metadata uppfattas som omständlig och tidskrävande. De senaste testerna vid universiteten i Finland och Sverige har också påvisat tidigare okända säkerhetsluckor och bristande användarvänlighet i systemets installationsprocess. Integreringen med den virtuella lärplattformen Moodle i eNOSHA version 1.6 har lyckats bra för en koppling till Moodle version 1.9, men då filsystemets grundstruktur ändrats i de senaste versionerna av Moodle så krävs det en uppdatering för att kunna söka i eNOSHA från Moodle 2.x.

Abstract [en]

This paper describes the iterative development process of a Learning Object Repository (LOR), named eNOSHA. Discussions on a project for a LOR started at the e-Learning Centre (eLC) at The University of Colombo, School of Computing (UCSC) in 2007. The eLC has during the last decade been developing learning content for a nationwide e-learning bachelor of information technology degree (eBIT) and a preparatory programme for the eBIT program (The Foundation in Information Technology, FIT). After analysing the specific needs at UCSC a decision was taken to develop a new repository since none of the analysed existing LOR systems could fulfil the UCSC requirements. There was an urgent need for a system that makes it easier for the eLC staff to sore and share course material. The system was designed with the main objectives to enhance the reusability of content and to support the content development process in a user-friendly way to assure user acceptance. We also identified the importance of a flexible LOR design to handle different type of content as well as various user contexts. The development process started with focus groups consisting of staff from UCSC and external project members from Sweden. A requirement analysis was carried out in December 2008, and based on the analysis a plan was drafted for the development and implementation of the system. As an overall system development method we used participatory design, where users have been involved in the design, evaluation and implementation of the system. Iterative testing and code revision for amendments and redesign and have been conducted at universities in Sri Lanka, Finland and Sweden according to the principles of Design science. Our aim with the chosen approach has been to develop a system that will meet the needs and requirements of the users at other universities countries than just only UCSC in Sri Lanka. Based on the testing of the system we had a positive response regarding the searchability and reuse of content but complaints on the uploading of content. Testing conducted in Finland and Sweden has revealed earlier unknown security issues as well lack of user-friendliness in the installation process. The integration of eNOSHA 1.6 with the Moodle virtual learning environment has been successful for the Moodle version 1.9 but with needs for redesign to work properly with the later Moodle 2.x versions.

Abstract [en]

ICT4D, here defined as the use of Information and Communication Technologies (ICT) in developing regions, can be seen as one of the most powerful and cost efficient ways to improve the standard of living in the developing world. Many regions in Asia have shown a rapid but heterogeneous development where information technology had a drastic impact on development but often with the problems related to ICT4D 1.0: lack of sustainability and lack of scalability.

This study analysed the Sri Lankan infrastructure for region-wide dissemination of blended learning in the 21st century based on the exploration of some selected ICT4D hubs and educational initiatives. The overall aim of the research was to observe, describe and analyse how the selected ICT4D initiatives and the creation of ICT4D hubs in Sri Lanka might support region-wide dissemination of blended learning and local development. A longitudinal case study has been the overall approach where a number of embedded thematic units were explored in long-term fieldwork conducted between 2006 and 2012. Data has been collected from a combination of observations, interviews, group discussions, surveys and document analysis.

Findings showed that several of the studied ICT4D hubs have contributed to the general development but the country’s internal digital divide has in fact grown, as urban growth has been so much faster than the growth in rural areas, leaving the country with geographic as well as socio-economic gaps. Some of the former war zones have definitely been left behind and there is a need for further support of the Eastern and Northern regions of the island. Sri Lanka has had an outcome that must be classified as better than average compared to other developing regions with increased opportunities for education and with some ICT4D hubs as multipurpose meeting points. Contributing factors to the successful development are the high literacy rate, the chain of ICT4D projects rolled out in the right order and a committed implementation of educational eServices. On the other hand there were other, more negative findings indicating that sustainability, knowledge sharing and inter-project cooperation and coordination have often failed.

The identified strength in the Sri Lankan model, which can be recommended for other parts of the world as well, is the way top-down management of infrastructure sometimes is combined with bottom-up grass-root activities. Other recommendations, that also are global, are to extend existing ICT4D hubs and upgrade them to more intelligent, autonomous and multi-service ICT4D routers that could also handle the future need for eServices in the fields of eHealth, eFarming and eGovernance.
