Have you ever considered the number of "new" technologies that have become obsolete during your lifetime. Have you ever considered how much differently you might see the world if you had never come into contact with items like vinyl records of rotary phones. Let me introduce you to a hypothetical 8th grade student and tell you a few things about the world as he or she might perceive it. You might want to brace yourself for this:
They were probably born in this century (year 2000+) and are about 13 years old.
The First Gulf War happened before they were born as did the Cold War and as far as they know, there has always been a large US military presence in the Middle East.
Keep in mind that this is just a partial list. Consider how differently these kids might perceive the world with all the new technologies they are experiencing. Consider the effects of MP3 players, hybrid cars, cell phones with cameras, and the internet. Any one of these technologies can drastically change how you understand and view the world. All music seems to be free online, new technology can solve any energy crisis and all pictures can be displayed instantly. Immediate communication is almost always available. And just about any question you can think up can be answered quickly online. This doesn't necessarily mean the physical or psychological needs of human development have changed. But this might mean that educators are challenged like never before to make their curriculum relevant to their students. Something to think about.
