              Answers to Activities
 
 
 
Activity 3.1  TB in a Fishbowl
 

Because this activity involves a classroom debate, there are no right or wrong answers. Students will either defend confinement or directly observed therapy during the debate. As you facilitate the debate, pay close attention to time, allowing each pair of students to speak for just a few minutes. This will keep the conversation from dragging. If the discussion stalls, you may need to suggest points of debate.

 
 
Activity 3.2  Streets of Hope, Streets of Despair
The products from this activity will vary depending on your local area and the facilities chosen for investigation. The census variables that students should research are provided on the worksheet. Students should provide a clear and detailed table that includes all of the data they found for each set of census tracts. Students should also have performed some basic mathematical manipulations on the data. For example, if they looked at multiple tracts, in order to compare the minority population of census tracts with a facility to census tracts without a facility, students will need to find the average minority population within each group of tracts.

Several national studies have found significant correlations between race and socio-economic status and the occurrence of hazardous facilities and others have found no correlation (see Appendix A for citations). Studies have been criticized on various points, including statistical techniques and geographic unit of analysis. It is possible that students will not find any significant difference between tracts with or without facilities. If this is the case, lead into a discussion about the significance of their findings. What implications does this have for the national studies that have been conducted?

 
 
Activity 3.3  The Geography of HIV/AIDS and Service Provision
 
Students’ reports will vary depending on your geographic location and the services available there. If you’re located in a large urban area, there may be a large number of services available within close proximity. If you’re in a rural area, services may be few in number and at a farther distance. You can use the following factors as a guide to assessing students’ reports:
