For my perception and process survey, I used short answer questions (I guess that is just how my English teacher brain works...) making it difficult to categorize my information. I had six of my co-workers respond.
There are two very practical uses for polling in my classroom. I've tried TestMoz before, but I usually use Socarative. I enjoy using Socrative for end of the hour formative assessments/ exit slips. I also use Socrative to let students give feedback during my speech classes. Students are required to give feedback using multiple choice questions (for example in their Sales speeches (persuasive speaking), they have the question: Did the presenter convince you to purchase the product? and then students have four options to choose from to answer the question).
