The purpose of this study is to derive the usability and improvement plans for the online practice content developed to improve the pro fessional practical skills of disability support workers in the community. For the study, a survey was conducted from March 1 to March 30, 2024 targeting 8 disability support workers and mid-level managers in institutions where online practice content lectures are operated, and improvement measures were derived by analyzing the importance and utilization. As a result of the analysis, the task with the highest average value was walking assistance in Set 1 (physical disability, brain damage, epilepsy) at 4.36, other emergency response in Set 2 (intellectual, autism, mental) at 4.32, other emergency response in Set 3 (kidney, heart, liver, respiratory, language, ostomy, urinary, face) at 4.13, and walking assistance in Set 4 (hearing, vision) at 4.40. At the end of this study, a qualitative study on learners’ responses, learning, and behavioral changes was conducted, and based on these results, suggestions were made for the use of online practice content that can be used by more systematic disability support workers, and additional research was proposed.
