I put bookmarks for all of us into a Diigo group. You can all join the group and share resources. Everyone can see the group; if you want to join, you need to be approved. (E-mail me once you’ve asked to join.)
Here's an example of a list that I created within my 'french300' account--created for classroom use. You can find this list at http://twitter.com/french300/newsinfrench To follow a list, log into your Twitter account, navigate to the list address, and click the 'follow this list' button. To create a list, log into your Twitter account, find the people and resources you want to have in the list, and follow these people and resources. With search.twitter.com/advanced, you can search by language. Go to Lists on your home page and choose 'new list', name the list, and add your people and resources.
For myself, I use Twitter lists to stay up-to-date on news--particularly certain kinds of news, e.g., cycling and French economic news. With students, I can imagine at least two 'quick and dirty' activities plus one 'lifelong learning' activity: 1. Have list feed up on screen when class begins--ask students to (a) find new vocabulary, (b) guess what headline might be about. 2. In computer classroom, have pairs or triads of students pick one tweet, go to the expansion, and be ready to report back to the class about the event. 3. Have students create a twitter list for the class using feeds that are interesting to them. AND/OR Have each student create a personal twitter list that all the others will follow. They can then ask each other questions about tweets in the lists.
Connections made through Twitter, Twitter lists, and social bookmarking are elements of one's personal learning environment. But you still don't have everything together in an easy-to-use format. The idea of a PLE is that it is a collection of resources, but you need a 'virtual filing cabinet' or a 'virtual notebook' you can easily consult. That can be the role of the 'personal start page'. That's great for us 'mature learners'--we know--or at least can experiment, reflect, and decide--which resources are useful to us. Our students need to acquire these skills--and it's very difficult in our current environment where everything is oriented toward the test, the grade, the credential.
