The course will focus on the design of Web survey instruments and procedures, based on theories of human-computer interaction, interface design, and research on self-administered questionnaires and computer assisted interviewing. The course will cover various aspects of instrument design for Web surveys, including the appropriate use of widgets (e.g., radio buttons, check boxes, general formatting and layout issues, movement through the instrument (action buttons, navigation, error messages), and so on. The course will draw on empirical results from experiments on alternative design approaches as well as practical experience in the design and implementation of Web surveys.
