For each of four "events" (Yellowstone
fire, Mt. Pinatubo eruption, Hurricane Georges, and Montserrat
eruption), each student is asked
to develop general conclusions about the short-term and middle-term effects of each events on their sphere. The students are also asked to do a comparison of the effects of the current event with their previous event analyses.
The objective of this exercise is to see if students can identify similarities among the events. This is called "making generalizations." Students need to use these generalizations to make predictions about what might happen on Montserrat in the short and long term. The specific generalizations they make will be dependent on the responses that each student provided for their previous analyses.
In order to score a students response to the comparison question, you should first review each of the responses to the analyses that have been completed. Use the following chart to rate the level of generalization that the student achieved.
The student identifies effects that occurred in each of the previous events and describes the effect in a general way.
The student identifies effects that occurred in each of the previous events, but simply lists the specific occurrences as they appear in the analyses.
The student lists no general effects nor effects that appear in select events.
