What do polarized student evaluation results say about my teaching? I taught my first class last quarter. The results for evaluations are very polarized. The raw data shows that my scores are either very high or very low for a majority of items. That implies some students loved the class and some hated it. 

Honestly, this teaching experience has been so tiring that I am seriously thinking teaching is not for me. My colleagues tell me it will get better but I am not sure how I feel about my average performance. I wish the evaluations weren't so polarized so I could know if I was overall an effective instructor or not. 

How would you make sense of the results?
Evaluations only tell you whether your students liked you or not.  Your main goal, however, is to have students learn the material and develop their intellectual skills, not to have them like you.

Have experienced colleagues sit in on your classes and give you feedback, and have colleagues look at your assessments and the students' performance on them (with appropriate attention given to how you prepared the students - at an extreme, assessments mean something different (but not nothing) if you've given the students the questions and answers in advance!).  This will give you much more useful information than student evaluations.
