Last spring, I had my CSC 216 students create active-learning exercises. They worked in teams. They created two exercises during the semester. One of the exercises was used later in the class In the summer, 4 student-generated AL exercises were used in class.

The Review Process: How It Begins One or more times during the semester, a peer-reviewed project is assigned Students select a topic from a list. Several students are allowed to select the same topic, But the number of slots is limited. Students are usually allowed to work in teams Apr. 22, 2009 Ed Gehringer efg@ncsu.edu http://research.csc.ncsu.edu/efg/expertiza
Step 1: Signing up for a Topic Apr. 22, 2009 Ed Gehringer efg@ncsu.edu http://research.csc.ncsu.edu/efg/expertiza
After the Initial Review • Resubmission phase. 2–7 days to revise work in response to reviewer comments. • Final review. 3–7 days to make final comments and assign scores. • Metareview phase. Students review each other’s reviews. Apr. 22, 2009 Ed Gehringer efg@ncsu.edu http://research.csc.ncsu.edu/efg/expertiza

Teamwork mimics the work environment Teaming skills are important to success Teams can tackle larger projects, which diminishes the effort of integration Why team assignments? Apr. 22, 2009 Ed Gehringer efg@ncsu.edu http://research.csc.ncsu.edu/efg/expertiza
All team members have access to a common submission area. Any member can revise the submission. Individuals review teams. This simplifies reviewing, and provides for more reviews. Teammates assess each other’s contribution to the team. This score can be factored into the student’s grade. How does Expertiza support teams?
