The following is a Morse Code  message: 
.... . .-.. .-.. --- / . ...- . .-. -.-- -... --- -.. -.--

"This mode of instantaneous communication must inevitably become an instrument of immense power"
 Morse,  1838


"Of all the marvelous achievements of modern science the electric telegraph is transcendentally the greatest 
and most serviceable to mankind … 
The whole earth will be belted with the electric current, 
palpitating with human thoughts and emotions … 
How potent a power, then, is the telegraphic destined to become in the civilization of the world! 
This binds together by a vital cord all the nations of the earth. 
It is impossible that old prejudices and hostilities should longer exist, while such an instrument has been created for an exchange of thought between all the nations of the earth."
Charles F. Briggs and Augustus Maverick, "The Story of the Telegraph", 1858

Watch the following two videos about how technology 
is changing in education.



Students' task


After reading all the information and watching the videos about the communication evolution, write a report about your impressions. 



  • Has the way children study changed for the better?
  • Do you use technology in your school?
  • Do you think studying with computers, iPads or mobiles can be more productive?
  • Do you enjoy using new digital tools? Why?
  • What are the pros and cons about using technology in the classroom?

Of course you can't use paper and pen for your report...
Choose one of these tools and have fun!
