What's for teachers?

What's for teachers?

Replies based on 45 European primary and secondary teachers participating the MELT project

What’s for repositories

Harvesting

e.g. in the MELT project

Federated search

e.g. Globe or LRE

However

In Journal of Computer Assisted Learning (JCAL), 24(4), 333-347 (2008)

As for the user...

Is federated search across repositories

and/or

harvested metadata from other repositories

enough?

Problem

Most times the interplay between LORs is about changing standards compliant metadata

and that has nothing to do with the user generated metadata which keeps the depth of the data

the depth?

Learning resourceExpert indexer addedmetadata (LOM)

Users interact with resources:

LOM

and other annotations

- social tags

- ratings

- sharable bookmarks & collections

But it is not the whole story...

Connections!

to study LORs and communities as a single system, rather than as a loose set of instruments, subject, objects and outcomes.

Margaryan and Littlejohn (2008) use Activity Theory - offers a holistic framework

A need

INVESTIGATION

Does such interplay make sense?

We study 3 different resource platforms and their tags

Data set

Differences in Design

Differences in Philosophy

Semantic similarities!

Cross-repository tag cloud

The cloud would use only information pair: resource-tag

Access to 968 most tagged resources in all 3 platforms

Cross-repository tag cloud

Takes advantage of other user's experiences (social navigation)

Gives priority to user's participation in social interactions through a dialogue to co-construct knowledge

“Social”

do go

Got issues?

Interoperability of user-generated metadata (e.g. tags, ratings, annotations, …)

Data-portability

Attention Profile Markup Language

Create profiles of repository's “attention”

Profiling LOR based on users' interest

This is my APML file. We could also have one for a LOR.
