Minds On: Significant Historical Communication Developments
Distribute a slip of paper with a name of a technological development on it to every student in the classroom.
Ask them to make a timeline beginning with the earliest development and ending with the latest. Students may discuss their decisions with each other, and collaborate as a team to sort themselves out (make sure dates are not revealed to students!)
Debrief Assessment: results will provide great opportunities to discuss students sense of historical timing. Ask students to identify from the list the three most important technological developments of all times and to justify their response
Action: Explore Mcluhan’s theory using any number of websources and powerpoint that explains his Tetrad concept. Important to situate this in the context of progress and emphasize that for Mcluhan technological progress is not necessarily progress towards a better world. Questions 1 and 2 are fairly simple-usually students struggle with questions 3 the most because it takes a broader historical awareness.
Some Assignment Possibilities:
a) Have students apply this theory to a list of technological developments from the past or present. Use web. 2.0 tools to present these to the class.
b) Have students collaboratively work on an invention of the future. Apply Mcluhan’s Tetrad to evaluate its effect on society….
c) Divide the class into groups and give them a hypothetical invention of the future (the same one for each group). Have students present their Tetrads and use a gallery walk (physical or digital) to provide each other with feedback….
