edWeek is sharing a visual representation of educational technology.

This is interesting on many levels. One, timelines provide information in a linear way. When you include hyperlinks to the idea of a timeline information becomes non-linear. The learner now can be provided quality information that relates to that concept and build on their overall understandings.

This brings me to the idea of the concept map. Concept maps have the potential to be interactive. Allowing the learner to build on knowledge and as a result build on their understandings with the material.

My other level of interest - educational technology has advanced. Have we? Have our schools?

Take a look at the timeline below
