JEM Repository for Learning Objects Antti Alamäki Olga Caprotti Matti Pauna University of Helsinki

Launched on January 2008 as an integrated service from the JEM Portal http://jem-thematic.net/lom

Purpose

Metadata Utilizing the current de facto standard: Learning Object Metadata (LOM) by IEEE “ attributes that are needed to adequately describe a learning object and can then be used for automatic processing of learning objects and for their classification ” Specifically designed for educational materials Modified to JEM’s needs (not all fields are used)

Utilizing the current de facto standard: Learning Object Metadata (LOM) by IEEE

“ attributes that are needed to adequately describe a learning object and can then be used for automatic processing of learning objects and for their classification ”

Specifically designed for educational materials

Modified to JEM’s needs (not all fields are used)

LOM Data Model LOM metadata descriptions include more than 70 fields in nine categories describing, for example structure and interactivity of the content topic classification school level and difficulty author(s) information file format, software environment, etc.. JEM Repository supports a subset of these elements

Select classification from taxonomy

Classifying Contents The classification describes the topics covered for example in a mathematics course as a tree MathTax (also known as LivingTaxonomy) is used as a basis for the JEM classification The LivingTaxonomy project is a community of educators, content publishers, and developers who aim at “creating global, open source, standards-based taxonomies for digital education”

Taxonomy (for Single Variable Calculus) Easy to organize contents for fine-grained educational modules
