BackgroundWearable activity trackers have the potential to be integrated into physical activity interventions, yet little is known about how adolescents use these devices or perceive their acceptability.ObjectiveThe aim of this study was to examine the usability and acceptability of a wearable activity tracker among adolescents. A secondary aim was to determine adolescents’ awareness and use of the different functions and features in the wearable activity tracker and accompanying app.MethodsSixty adolescents (aged 13-14 years) in year 8 from 3 secondary schools in Melbourne, Australia, were provided with a wrist-worn Fitbit Flex and accompanying app, and were asked to use it for 6 weeks. Demographic data (age, sex) were collected via a Web-based survey completed during week 1 of the study. At the conclusion of the 6-week period, all adolescents participated in focus groups that explored their perceptions of the usability and acceptability of the Fitbit Flex, accompanying app, and Web-based Fitbit profile. Qualitative data were analyzed using pen profiles, which were constructed from verbatim transcripts.ResultsAdolescents typically found the Fitbit Flex easy to use for activity tracking, though greater difficulties were reported for monitoring sleep. The Fitbit Flex was perceived to be useful for tracking daily activities, and adolescents used a range of features and functions available through the device and the app. Barriers to use included the comfort and design of the Fitbit Flex, a lack of specific feedback about activity levels, and the inability to wear the wearable activity tracker for water-based sports.ConclusionsAdolescents reported that the Fitbit Flex was easy to use and that it was a useful tool for tracking daily activities. A number of functions and features were used, including the device’s visual display to track and self-monitor activity, goal-setting in the accompanying app, and undertaking challenges against friends. However, several barriers to use were identified, which may impact on sustained use over time. Overall, wearable activity trackers have the potential to be integrated into physical activity interventions targeted at adolescents, but both the functionality and wearability of the monitor should be considered.

Federal law requires all students, including those with significant intellectual disability, to make progress toward grade-level general education standards. The alignment between standards, curriculum, and instruction is vital for ensuring equitable opportunities to learn. Commercially available curricula attempt to support teachers and students by aligning instructional materials to standards, but few studies exist to verify this alignment. Those that have been conducted for general education curriculum have not been promising. This study uses the Links for Academic Learning protocol to evaluate the alignment of curricula designed for students with significant intellectual disability (SWSID) that mark themselves as aligned to grade-level standards. Findings related to the alignment between the standards, lesson objectives, and lesson content are reported. The researchers discuss implications related to the adoption and use of curricula specifically designed for SWSID and the need for additional research in this area.
