<p>Alexandre, I am not trying to say you’re wrong, but the table (containing 3% GSI teaching) you are looking at is misleading. In fact, they even provide a more relevant table right below: GSI Teaching as a percent of total credit hours taught is 21 percent. That was in 2006-2007 and based on my personal observation, it seems quite higher that 21 percent in recent years. </p>
