Many of the programs and initiatives that we evaluate today are technology-based. It is not uncommon for initiatives to provide information to their target audiences via websites, while other interventions are delivered with software applications to mobile, handheld or other devices. To properly evaluate such initiatives, the evaluator must consider the usability (user-friendliness and accessibility) of the technology components. This demonstration at AEA 2011 provided participants with an overview of the most common usability method--the one-on-one usability session, including the think aloud procedure. Participants learned how to develop a usability testing script, how to recruit participants, how to run a usability session, and how to analyze the data. #HowTo #MixedMethodsEvaluation #usability #Research,Technology,andDevelopmentEval #NeedsAssessment #Collaborative,ParticipatoryandEmpowermentEval #2011Conference #QualitativeMethods #IntegratingTechnologyintoEvaluation #DistanceEdandOtherEducationalTech
