I have had students use this as a place to collect short stories for our short story unit. I also have it as an option for annotated bibliographies for my seniors.
The intellectual work is the same - students find resources, summarize them, and evaluate their use - but the visual collection space is more engaging and visually organized around topic (instead of forcing resources into alphabetical order).
Below, you have the collected pearls of my Fall 2012 Senior Dystopian Literature class. They commented on each pearl and wrote a brief summary, explained how the resource connected to their book, and cited the source.
3. Add New Pearltree titled
3. Use advanced search, various genre terms, etc to find 5 short stories
4. Take the story URL and 'Add Pearl' --> 'Web Page'
If you are having difficulty, find 5 stories and email yourself the links.
