ItemMastery of Assistive Technology in K-12 Education(Georgia Institute of Technology, 2024-08) Satterfield, Richard (Ben) ; Walker, Bruce N. ; Milchus, Karen ; LaForce, Salimah ; Griffiths, Patricia ; DeStefano, Lizanne ; Blake, MatthewThis article describes the evaluation of a prototype of the Continuum of AT Mastery (CATM), an instrument developed for measuring individual progress toward mastery of assistive technology (AT). In this second of two one-year studies, we examined the applicability of the CATM in K-12 educational settings. This manuscript includes results of field testing of the CATM in K-12 schools and presents results of inter-rater and test-retest reliability. item_description: This is the compilation of data collected from focus groups, field testing, interviews, and analysis from a study of the instrument known as the Continuum of AT Mastery (CATM) in K-12 settings.

ItemThe Development of a Measurement Tool for Mastery of Assistive Technology(Georgia Institute of Technology, 2021-06-30) Satterfield, Richard (Ben) ; Walker, Bruce N. ; Milchus, KarenThis report describes the development of a survey tool used to measure and assess “mastery of assistive technology”. A Delphi Panel comprised of experts in the area of Assistive Technology (AT) was gathered to explore the question of “What is mastery of AT?” For the purposes of this study, mastery was defined as becoming a “power user” of AT. Panelists were asked to identify what characteristics are associated with being a power user of AT. The panel gave these characteristics Likert Scale rankings as to their applicability as a predictor of becoming a power user and as an indicator of having become a power user. The rankings were compared, and the panel was asked to revisit the rankings in order to identify the most important factors. The panel identified 12 predictors and 14 indicators that they felt were highly predictive of becoming a power user or indicative of being one. These factors were analyzed and found to coalesce around four constructs or areas of mastery: (1) Experience (Usage) with AT; (2) Proficiency with AT; (3) Knowledge of AT; and (4) Personal Connection with AT. An online survey-based tool for measuring AT mastery was developed based on these constructs and presented to the panel for feedback and critique.
