Here are my official teaching evaluations, including comments where they were submitted in an (unidentifiable) electronic format. These are from students in Linear Algebra (spring 2016), Junior-Year Writing (spring 2016), and Multivariable Calculus (fall 2015) at UMass; Calculus 1 (spring 2015), Multivariable Calculus (fall 2014), and Calculus 1 (fall 2013) at UVic (fall 2014); and Multivariable Calculus at Brown (fall 2011). My teaching evaluations from 2016-2017 will be posted soon.
On a related note, an anonymous illustration (fall 2013):
