  • The second study addressed reflection on information management of web-resources using a personal tag cloud. This system is called ReScope. The tag-cloud shows keywords that a participant has assigned to interesting web-pages while adding them to the personal bookmarks. The size of each keyword shows how often this keyword has been totally applied. The color on some keywords informs the participant how often these keywords were recently used. In order to capture “reflection”, the participants were asked to write the reasoning about their tag cloud down.
  • The design of the tag cloud is an attempt to model contextualized reflection support. From the underlying model reflections were expected to be related to the factors rhythm, value, and connections. After a 9 week period of public use of ReScope the analysis of the reflective notes basically confirmed the expectations. Besides the concept related factors value and connections , also an almost equal amount of reflections related to the rhythm factor was found. Furthermore, the reflections also seem equally referring to the reflection types planning , monitoring , and evaluating that were identified to be relevant for knowledge workers.

    1. 1. Reflection support using multi-encoded tag-clouds Christian Glahn Marcus Specht & Rob Koper MUPPLE’09 Workshop Nice, 29 Sep 2009
    2. 2. How to support meta-cognition in PLE?
    3. 3. Where is the learning in personal learning environments? For those who don’t see the relation to mash-up’s
    4. 4. ReScope + Note taking mash-up
    5. 5. Reflection support for personal information management <ul><li>Global tag usage </li></ul><ul><li>Bookmark feed </li></ul>
    6. 6. Global tag usage = Relevance of concepts Font size
    7. 7. Bookmark feed = Recently used concepts = Development of concepts Tag colour
    8. 8. Multi-encoding contextualises tagging information

    10. 10. Does the reflection on the tag cloud confirm the contextual factors suggested by the framework?
