Currently I am taking a class offered by my school district where the focus is on using technology in the classroom. There was a discussion about how POD stands for "play on demand". So that got me thinking about an idea - LOD or "learning on demand".
Teachers and students collaborating and creating items such as documents, slideshows, videos and audio files and then posting them on a website. They then could access these resources at any point in time via the web and/or by downloading them onto a computer or iPod. A teacher could access it to share with another colleague or to reflect on a lesson. Students could access these resources to review a concept, study for an assessment or to learn content that was covered during an absence.
By creating this type of environment it would invite the concept of accessing resources to "learn on demand"!
