During the students' justification of their groupings, the teacher will need to informally assess student misconceptions and attitudes toward radioactivity so that the lesson can be adjusted to address these.
In addition, the following checklist may be used to judge student responses:
1. Do you have AT LEAST 15 terms in your List-Group-Label?
2. Is each term grouped in a logical manner?
3. Does your List-Group-Label show considerable effort?
4. Is your List-Group-Label show depth of thought and creativity?
At the end of the during activity, after activity, or unit, you may have students revisit this list to add terms, assess their groupings, and make changes based on new knowledge they have gained.
