Through the years many of us have seen how technology helps education. I remember, 1960's classrooms, with a TV monitor in the front to watch a class, it was spectacular. Then followed the audio tape, that was used for foreign languages' learning, with the introduction of VCR's and Camcorders, high-tech's trainings were available through Beta or VHS formats, CD- Interactive, DVDs, but all of them lacked of real time human interaction. In nowadays, the learning process had a quantum- leap with the real time human collaboration, e-learning with through personal computers, tablets, etc, give new virtual tools, and simulators, that extend far beyond, the educational possibilities, breaking the gaps, without frontiers, joining communities around the world. With your excellent blog post, you brought me a pleasant flashback...Thank you, Mr. Reg Johnson, for sharing your insights. Deeply appreciated.
