Abstract Results from self-reflection tools for schools’ digital capacity can lead to evidence-based decisions within the school community and/or the development of an action plan for a better integration of digital technologies. Thus, it is important that the information derived from self-reflection tools is complete, accurate, and relevant. However, usually self-reflection tools do not show evidence of the quality of the information provided. In this paper, we focus on SELFIE, a new, comprehensive and customisable self-reflection tool for schools´ digital capacity, and we analyse the quality of the information that it provides. In particular, we look at discrimination and difficulty item parameters (using item response theory), we analyse the reliability (using Cronbach’s alpha and Omega) and the construct validity (using confirmatory factor analysis) of its core items. We find support for the tool quality and conclude that schools using SELFIE are provided with accurate information on their digital capacity. Additionally, we discuss ideas for further improving the tool and future research work. The innovative design of the SELFIE tool and the psychometric analyses of its core items are a novelty in the field of schools' digital capacity and can provide insights for the development of self-reflection tools for school communities.

捕捉学校的数字能力:SELFIE 自我反思工具的心理测量分析

摘要 学校数字能力的自我反思工具的结果可以导致学校社区内基于证据的决策和/或制定行动计划以更好地整合数字技术。因此,重要的是从自我反思工具中获得的信息是完整、准确和相关的。然而,自我反思工具通常不会显示所提供信息质量的证据。在本文中,我们重点介绍了 SELFIE,这是一种用于学校数字能力的全新、全面和可定制的自我反思工具,我们分析了它提供的信息的质量。特别是,我们看区分度和难度项目参数(使用项目反应理论),我们分析了其核心项目的信度(使用 Cronbach's alpha 和 Omega)和结构效度(使用验证性因子分析)。我们找到了对工具质量的支持,并得出结论,使用 SELFIE 的学校可以获得有关其数字能力的准确信息。此外,我们讨论了进一步改进工具和未来研究工作的想法。SELFIE工具的创新设计及其核心项目的心理测量分析是学校数字能力领域的创新,可以为学校社区的自我反思工具的开发提供见解。我们讨论了进一步改进工具和未来研究工作的想法。SELFIE工具的创新设计及其核心项目的心理测量分析是学校数字能力领域的创新,可以为学校社区的自我反思工具的开发提供见解。我们讨论了进一步改进工具和未来研究工作的想法。SELFIE工具的创新设计及其核心项目的心理测量分析是学校数字能力领域的创新,可以为学校社区的自我反思工具的开发提供见解。
