At the recent Interaction Design & Children (IDC) 2019 conference, INIT Lab Director Dr. Lisa Anthony gave a crash course in quantitative research methods, and how to apply and adapt them to child-computer interaction. Topics covered include: the types of research questions that can be answered with quantitative methods, experiment design, data logging, data analysis, and simple statistical techniques, as well as important considerations for conductive quantitative work with young children, especially attentional issues that may affect data quality. The course notes and sample data used during the course are now available for download! If you find the course materials useful, feel free to let us know!
