The days of the static, semantic, classroom are over. Now, with the rise of real-time video, teaching and learning becomes dynamic, semaphoric, changeable and semiotically recordable for the eternity of history.
By employing live video clients like Skype and iChat, online distance learning takes on a new dimension.
We are no longer tethered only to semantic text. We can now invoke the power of semiotics and the elegance of learned semaphores like American Sign Language.
One of the merits of distance learning is the students can login any time they like and do the work as they wish on their time.
We no longer need the structure of a traditional classroom because both student and instructor are freed to login and tune in on the Internet — anywhere in the world at any time — as often as their desires and wishes want to take them into new mixes of semaphoric, semantic and semiotic learning memes.
