Create directions. The top of the questionnaire should have a brief statement about the purpose of the questionnaire. This will give those who will ultimately fill it out an understanding of what you hope to achieve. This will motivate them to answer questions openly and honestly. Make every effort to keep the answers to the questionnaire anonymous.
Draft the questions. You have full control over the questions, so draft them with the goal of attaining the most pertinent information possible. As such, try to keep the questions focused on certain aspects of your program. For example, a question could read, "What worked best within the lesson on Shakespeare?"
Draft the final questions. You have already asked specific questions of your choosing. At the end, you should draft a final overarching question. This will allow the respondent to state anything they wish to cover that wasn't already covered in the specific question. For example, this could read, "Any other comments?"
