This online course introduces students to the design and implementation of online survey data collection instruments. The course is both hands-on and conceptual. It begins by discussing what is unique about web surveys and when their use is most appropriate, followed by an introduction to survey errors that can affect the quality of web survey data. Small groups of students will each develop a research problem and a questionnaire to address their problem, designed for online administration. They will pretest the question wording, program the questionnaire using a web survey development platform (no programming experience is required), and assess users' (respondents') experience while interacting with the web-based instrument. Students will also develop basic plans for data collection. Finally, each group will present its problem, online questionnaire, evaluation, and plans to the rest of the class.
