Improving Validity and Reliability in Children’s Self Reports of Technology Use

Abstract

Researchers working in child computer interaction are constantly seeking new methods and new techniques that will enable them to carry out more valid and more reliable research. Much of this research typically considers the design and development of new products and of new interactive techniques and researchers seek to understand how easy such innovations are for children, how much fun they are to use and how attractive they may be for use.

The impact of prior technology use on the children’s responses in those contexts is the core concern of this thesis. The thesis provides a set of tools (survey instruments and guidelines) that can be used by the CCI research community to ascertain the prior experience of children with any technology and with any task. These tools are generated using theory, experience and literature and are validated through user studies.

The PETT survey tool comprises three questionnaires, CTEQ, CTUQ and CTHQ and an associated user guide that clearly articulates how to use PETT and demonstrates the flexibility of PETT to be used in many contexts. The guidelines (RWC, SWC and SRT) can be applied on three levels, for general use in research with children, in the design of surveys and in the specifics of designing self-report tools for prior technology experience.
