Quizzes:

 

Pre-Quiz

 

Ozone questionnaire I: 

 

To assess student prior understanding of ozone depletion. 

 

Post-Quiz

Ozone questionnaire II:

 

This is a questionnaire developed to further assess student understanding of ozone, ozone depletion and how ozone depletion influences Australia.  Teachers may want to delete some items they did not cover.

 

Note:  I would be very interested in the results of any students taking this questionnaire since I’ve use a similar questionnaire before.

 

 

Assessment suggestion:  If students have completed some the learning activities as a group, one possibility is to take an average score of all the group members on this assessment item.  The idea here is that if students know their final mark will be a combination of their groups marks, they are more likely to make sure each student in the group understands what’s going on.  One common problem in group work is that one person grasps the ideas quickly and the rest of the group cruises behind.  Although some students may not like the idea of having to rely on other students for their own mark, students can be encouraged of the value of working in a team.
