When I log into BlackBoard, I see about 30 different things I can do, and for each I have to click a link and go to a page to do the action.  Twitter strips away the features, instead using an inherently flexible textual space to facilitate communication, accomplishing the same goal of other feature-ridden “course technology.

I see Twitter’s artificial limit on post size as an important factor in classroom success.  First, it keeps the information space managable, meaning information is economized and easily retrievable

Twitter’s short form as a communication equalizer

HOW TO CREATE A ONE-MINUTE LECTURE Professors spend a lot of time crafting hourlong lectures. The prospect of boiling them down to 60 seconds — or even five minutes — may seem daunting. David Penrose, a course designer for SunGard Higher Education who developed San Juan College's microlectures, suggests that it can be done in five steps: 1. List the key concepts you are trying to convey in the 60-minute lecture. That series of phrases will form the core of your microlecture. 2. Write a 15 to 30-second introduction and conclusion. They will provide context for your key concepts. 3. Record these three elements using a microphone and Web camera. (The college information-technology department can provide advice and facilities.) If you want to produce an audio-only lecture, no Webcam is necessary. The finished product should be 60 seconds to three minutes long. 4. Design an assignment to follow the lecture that will direct students to readings or activities that allow them to explore the key concepts. Combined with a written assignment, that should allow students to learn the material. 5. Upload the video and assignment to your course-management software.   http://chronicle.com Section: Information Technology Volume 55, Issue 26, Page A13

What it is:  Education Diigo offers k-12 and higher ed educators premium Diigo accounts!  The premium accounts provide the ability to create student accounts for whole classes, students of the same class are automatically set up as a Diigo group so they can easily share bookmarks, annotations, and group forums, privacy settings so that only classmates and teachers can communicate with students, and any advertisments on Education Diigo are education related.  If you aren’t familiar with Diigo, it is a social bookmarking website where students can collaborate on the web.  Diigo works in to a project based learning environment nicely and allows for exploratory learning and collaboration.  

Education Diigo is an outstanding place for students to solve problems together.  Provide students with a problem and send them on a web scavenger hunt to find the answer, students can post their findings and notes about their findings on Diigo.  Students can collaborate online to solve the problem.  Education Diigo is also a great place for “teachers to highlight critical information within text and images and write comments directly on the web pages, to collect and organize series of web pages and web sites into coherent and thematic sets, and to facilitate online conversations within the context of the materials themselves.”  This feature makes Education Diigo a great place to create webquest type lessons and virtual field trips around the web.    Diigo also allows teachers to collaborate and share resources among themselve. Education Diigo is a must for students who are learning to complete web-based research!
