4/16 Homework

Hit the net and go to the library to conduct research regarding the dimensions of wireless futures.
We have scheduled oral
presentations for each of you next time.

1. Compile your study at your own blog. However,
please post your titles of findings and links to your blog of search results
at the class agenda of 4/30.

2. As a backup plan, please keep your presentation materials in a storage media such as USB drive in case the radio signal is too weak to use in the classroom.

4/30 class

Use your blog to present the research you have done regarding the dimensions of wireless futures.

Second time of team meeting to conclude your team analytical reports and prepare for
the oral presentation and defense next week.

class discussion-
DIY futures of wireless worlds and develop a personal
Scenarios in the mobile world in 2015

Form of brainstorming activities

1. Organize a 2-person team

2. Each team work on the defining dimensions sheets handed out in class and go through the 14 dimensions.
In case both of you in a team cannot reach a common ground on any of the dimensions, just average your opinions with equal weights on the disagreed dimensions.

3. Based on your team judgements on each of the dimensions, profile a personal life in a day of the mobile world in 2015. This John or Mary in your story could be you, your family, or a total stranger as you wish.

4. Oral presentation and defense: One member of the team plays the role of analyst and presents orally the opinions in each dimension. The other plays the role of creator and presents the scenario of the imaginary personal story of life in 2015.

----
If you ask the right questions, you will come up with the answers you really want.

The difficulty does not lie in thinking out the great answers but in coming up with the good questions.

Analyzing is great but works best with creations.
