Understanding Usability Testing in Observational Methods for Child Behavior Analysis
This session aims to enhance participants' skills in usability testing through observational methods when working with children. Participants will explore challenges in observing children, gain insights into various observation techniques, and learn how to conduct effective observational studies. Key objectives include discussing the pros and cons of different methods, logging observations, and measuring effectiveness, efficiency, and satisfaction. By the end of the session, participants will be equipped to implement best practices in child observation to gather meaningful data.

Objectives • At the end of this session, participants will be able to: • Describe the problems of observing children and suggest ways to limit their effects • Discuss the pros and cons of different observational techniques • Log observations
Methods • Observational • Think-aloud • Co-operative evaluation • Co-discovery • Experimental
"The things we collect statistics about are primarily those things that are easiest to identify and count or measure - which may have little or no connection with those factors of greatest importance."(Norman 1994).
What might we measure? • Effectiveness • Efficiency • Satisfaction ISO
Observational methods • Video • Protocol analysis • Interpretation
Experimental Methods • Choice (of subjects) • Control (of variables) • Reliability (of data) • Validity (of results)
