If you define "technology" as the above, then yes. Once a upon a time, blackboard and chalk used to be the technology of that era. Then there's the whiteboard and marker pens. Now, the Smartboards with internet connection. The latest is tablets such as iPads and Samsung Galaxy Tabs, to name a few brands familiar to most of us. So, what's the next "Technology"? You tell me!.
It's not the technology that matters. It's HOW an educator uses it to make the class more engaging where learning and understanding and making meaning of the lesson takes place. It's HOW the device or items assist students into able to make meaning and connection of his prior knowledge with the new knowledge he is learning in class. It's not the brand that counts. It's just HOW we, educators make use of it to enhance our students' learning and understanding at the end of each semester.
