The evaluation of the following series of questions depends entirely on the use of these units by the educator.
 

1.  How might the information be presented so that there is a good continuum between the three units?
 
 

2.  What are some additional sites that can be used for background information and what are the benefits of each?
 
 

3.  How much time previous experience with computer technology is necessary for students to perform the units, and  how much time is needed for all the students to get on the same page technologically?
 
 

4.  How can these units be used as a basis for students to create their own GIS data bases, particularly for Unit 3?
 
 

5.  Can students be grouped in such a manner so that the information gained be shared with other students in other locations, and/or can groups be formed so that students can help shoulder the responsibilities particularly with Unit 3?
 
 

6.  The ability to download GIS maps from the various sites should be a part of the performance based assessment.
 
 

7.  After GIS maps are downloaded, they can be printed and transparencies made to demonstrate overly abilities of GIS.
 
 

8.  There are some graphic software packages such as NIH Image and GIS Graphic Manipulators which allow the overlays to manipulated digitally.
