TrAgLor: A LOM Based Digital Learning Objects Repository for Agriculture Zeynel Cebeci, Yoldaş Erdoğan, Murat Kara Çukurova University Faculty of Agriculture, Div. of Biometry & Genetics 01330 Adana, TURKEY cebeciz@gmail.com The 4th International Scientific Conference, eLSE "eLearning and Software for Education", BUCHAREST, April 17-18, 2008
- any entity, digital or non-digital, which can be used, re-used or referenced during technology supported learning (IEEE LTSC, 2002) • any digital resource that can be reused to support learning (Wiley, 2000) • can include anything that has pedagogical value - digital or no-digital such as a case study, a film… (Karman & Koohang, 2005) What is learning object? • any reusable digital resource that is encapsulated in a lesson or assemblage of lessons grouped in units, modules, courses, and even programs (McGreal,2004) • digital resource in any size and format which can be online accessible and reusable in teaching and learning via online networked environments in order to achieve the desired learning outcomes or educational objectives(Nash, 2005) Src: McGreal, R. (2004).
I am a learning object Objects waterfall • Medicine • Biology • Physical education • … What is learning object? METAPHORS - Atoms- Legos- Waterfalls learning object:- educational purpose, support learning, pedagogical structure- small, granular, reusable- interoperable- in building lessons, courses and curriculums
Learning Objects Repository = LOR Learning Objects Repository = LOR Learning Resources Repository = LRR Learning Repository=LR LORs are the catalogues of the e-learning era. They will be the fundamental first step in knowledge discovery and object exchange. They will provide the foundation for future learning and commerce (Richard et al, 2002) In order to make LOs are accessible and exchangeable between learners and learning systems, there is a need for the systems that organize, index, search and deliver them. Web-based systems, specialized for facilitating these tasks are generally called as learning object repositories A typical food repository in Black Sea Region of Turkey
Accessing LOs… Google Altavista Lycos Alltheweb Yahoo Excite … Search engines Directories Portals “growing tomatoes” Google: 153.000 results -too many results -HTML,HTML,HTML -further check is required - no learning purposes ?
LORs… • Why? • Difficulties in finding discipline specific resources • Difficulties in filtering resources found for a personal learning objective, • Lack of technical features and quality assurance of the resources, • Lack of educational value and properties of the resources, • Uncertainty in compliance criteria of the content for a specific learning purpose. • What does? • Collection, presentation, and management of learning objects in a central repository which can globally be accessed on the Web, • Cost savings by avoiding repetitions in learning resources development, • Promoting high quality objects production and sharing, • Enabling learning resources exchange. • Who uses? • LEARNERS • teachers, academic staff in f2f and distance education programmes • course authors, learning content developers

In a study carried out by Tzikopoulos et al. (2005), 59 repositories were examined in different aspects. They reported that 3,200 of 881,000 learning resources are directly relevant to agriculture only. This evidently points out that there is a need for object repositories storing agricultural learning objects, and enabling easy access to these objects, where informal and lifelong learning need is too high like agriculture and food.
