These dates should be placed in the appropriate part of the matrix in the student handout. Each technology should be associated with the appropriate room or rooms. Class Session 3 1. After the matrix is filled in, have students look again at the graph on page 22 for the following discussion. Most of the lines are steeper in the middle than they are at the ends.
Diffusion tends to be slow at first.
Most diffusions are fastest when about half the population has gotten a particular technology and half have not yet gotten it. Class Session 4 1. Draw a sample of a Diffusion of Technology Timeline on the board using the years where technology had diffused to half of American households as the time where a particular technology would show on the timeline. Have the students use their matrix to create their own version of a timeline. Assessment Recommendations 1.
