1402 What Happened in Class

Sal gave his speech on marijuana legalization.

We went to the lab and worked on sections of the persuasive speech. Specifically, we worked on how to make the problem a problem for our audience. Students signed "contracts" agreeing to use the Monroe Motivated Sequence outline.

Next class:

Outline due (Nov. 30)

Following are examples from the lab session:


Need step (problem demonstrated with evidence):

Leafblowers are an inefficient means for disposing of leaves because they:
• Put out too much pollution pollution (a person can drive a car from NJ to Indianapolis and put out less pollution than one leafblower in 20 minutes)
• Are too noisy. Leafblowers put out 160-190 dBA while lawnmowers only put out 95 dBA
• Stir up chromium and other toxins put out by automobiles, put it into the air where we breath it. One study conducted by the American Lung Association examined types of materials or toxins found in street dust. Found among the particulates examined were traces of arsenic, cadmium, chromium, nickel, and mercury.

Example of visualization step:

If we ban leafblowers, our mornings will not be disturbed with loud noise. We can leave our house windows open on Indian summer days in the fall.

There will be no more piles of leaves at the curb to cause traffic congestion and accidents.

The instruction suggested that students write a paragraph about what the world will be like if their solution to he problem is adopted.
