Digital Library of Learning Objects

Learning Object is any entity, digital or non-digital, that may be used for learning, education or training.

Digital library is controlled collection of digital information objects. Controlled means that it contains only those objects, which were controlled and validated by librarian (librarian can decide which objects can be included into library). Also users must be controlled, which means that mechanism for restricted access to digital objects must exist, because of economic and/or legal reasons.


Similar projects

Before taking a decision about the library architecture, we analysed available standards and several projects developing digital library of educational materials. We have located two categories of relevant projects:

broad digital libraries covering the whole educational spectrum as ARIADNE or GEM

specialised digital libraries dealing with educational materials for some disciplines only as SMETE or iLUMINA.


ARIADNE

Alliance of Remote Instructional Authoring and Distribution Networks for Europe was supported by the EU 4. FP

The ARIADNE Knowledge Pool System, developed within the project is a Europe-wide distributed repository for pedagogical documents, with associated indexation and query tools. One of the key features of the Knowledge Pool System is the underlying metadata specification.

GEM - Gateway to Educational Materials

Created through the efforts of several groups, including US department of Education, the national Library of Education, and a team from Syracuse University. The goal of the project is to provide teachers with a broad range of educational materials on the www. Allows users to search for educational materials in variety of formats as

lesson plans, educational Web pages, books for sale, web pages for national museums

by subject, keyword or grade level. Materials are reviewed

http://www.gemInfo.org


SMETE

A federation of collection and service providers to support the learning and teaching needs of a broad community of learners in the Siences, Mathematics, Engineering and Technology Education.

Is much more than a traditional academic library in digital form, it is a digital learning community where learners and instructors can come together to locate and discuss teaching and learning. It provides its members with mechanisms to adapt and build on the work of others

http://www.smete.org


iLumina

A digital library of undergraduate teaching materials for chemistry biology physics mathematics computer science

The resources range in type from highly granular objects such as individual images and video clips to entire courses. IMS compliant metadata. Library resources can be browsed by discipline, resource type, structure, media type or contributors. The hierarchical taxonomy has three levels


DILLEO -Digital Library of Learning Objects

Targeted to teachers and students of information systems economics tourism management

Before adding to library every learning object is reviewed and proper metadata is provided.

Metadata based on ARIADNE Educational Metadata 3.1, published in May 2001. This schema is compatible with LOM and was modified to conform our requirements.


DILLEO - architecture

Three-tier architecture implemented in following tiers is used: centralized database server Microsoft SQL

Server 2000 together with Microsoft Index Server

business logic implemented in Transact-SQL stored procedures and specialized .NET application objects

user interface based on HTML/DHTML/JavaScript interface and ASP.NET code.

DILLEO - Multilingual support

User interface is implemented with support of multiple languages. Defined languages can be easily switched in-between.

Metadata of every document are in so-called primary language, system offers to input metadata also in all other defined languages.

All languages are defined dynamically; they can be added or removed without any need to change any system code.


DILLEO users (1)

User types have hierarchic levels of rights - rights of lower level users are subsets of rights of higher level users.

Types of users not-registered user registered user librarian system administrator

Not-registered user - all visitors until they obtain username and password in the registration process. Can search and view public learning objects.


DILLEO users (2)

Registered user - successfully went through the registration process and owns username and password. Has the right to search and retrieve all learning objects and to submit new learning objects into the library.

Librarian – has higher rights for specified group of learning objects (usually one object in one topic and its subtopics), defined by system administrator. In these topics he can accept learning objects submitted by registered users and make them available for registered and/or not-registered users. Librarian has right to move and delete learning objects in a topic and is also responsible for proper metadata.


DILLEO users (3)

System administrator is responsible for continuous operation of the whole Dilleo system. He manages all users and their rights to objects and also has full rights to all parts of the system. He can change all system settings (for example primary language of communication).

DILLEO - browsing

The objects are organized in the tree-like structure of topics, starting with general topics such as Mathematics or Computing in the top-most level and ending with specific topics such as Pattern recognition in the bottom-most level.

There are many topics already defined in the library, which often means that finding the specific topic is not an easy task. To facilitate the topic finding, the library provides a simple topic search – user just writes in the keywords, pushes the button and the system outputs the list of all suitable topics.


DILLEO – search

Simple search has been designed to have as simple user interface as possible, yet giving precise and usable results. User has just to fill in the keywords specifying the desired object and click on the search button The search query becomes processed and non-trivially compared to the object metadata in active language.

Advanced search - the author and keywords are searched separately and fulltext search looking inside the stored text documents can be used to refine the search results.


DILLEO - taxonomy editing

In the installation script for library we provide the default tree of topics, but when using the system, administrators or librarians may freely decide to make any changes necessary. In fact, it is possible to delete all topics and create completely different structure, without needing to re-install or even restart the application.

Taxonomy editing include topic adding topic removal and topic metadata editing.


DILLEO - objects management

The new object is always put under one of the topics. The librarian responsible for given topic reviews the object and decides whether to accept it into the library. Librarian is also responsible for maintaining the multi-language metadata of all objects in his topics.

Librarian may always decide to move any object into another topic, or even delete the object. For every user it is possible to specify the access rights to the object.


DILLEO - security aspects

The communication encryption using HTTPS/SSL protocols as the basic protection element has been used.

Very important security aspect is the implemen tation of access rights to the library objects. The access rights idea is based on access rights to the directories and files as implemented in WindowsNT or Windows2000.

All access rights in the system are defined for the role. The role in the library context has similar meaning as the users group in the Windows system.


E-learning Pattern Language (1)

Patterns provide a way of capturing and sharing good practice and are used in a number of disciplines, including architecture, software engineering, user interface design and education.

Our aim is to provide a pattern language that will help users to choose the types of learning objects to have on-line, based on the educator’s required learning objectives and outcomes.

The eDILEMA pattern language was developed by Janet Finlay and Liz Allgar.



Captures patterns that support educators in making decisions about the choice and use of learning objects in the EDILEMA repository. When constructing e-learning courses through the design and use of learning objects, educators need to consider a number of key questions: What type of learning object is appropriate?. How can learning objects be combined to create

a learning environment? How should a learning object be designed?



The pattern language is available at http://www.lmu.ac.uk/ies/comp/research/isle/ELearningPatterns/

The E-learning pattern language website will provide educators with an online resource to access the patterns and help select and design learning objects, which may in turn be integrated into a WebCT course or equivalent.

As part of the website, educators are encouraged to feedback on the patterns in the language and contribute to the pattern language by writing and submitting patterns. The intention is that the pattern language will belong to the community and evolve through use.
