Psychometric evidence for the universal design for learning 3.0 teacher implementation questionnaire (CID-DUA3): development and preliminary validation

Research has focused on the development and preliminary validation of a new psychometric tool, the Universal Design for Learning 3.0 Teacher Implementation Questionnaire (CID-DUA3). This instrument aims to assess the self-reported frequency of specific teaching practices aligned with the UDL 3.0 framework, which is designed to reduce educational barriers and enhance student participation and progress.

Why it matters

The development of a validated instrument to measure the implementation of Universal Design for Learning 3.0 is strategically important for understanding the efficacy and adoption of inclusive educational practices. This enables better evaluation of pedagogical approaches and informs policy decisions regarding educational design and professional development.

Key insights

• The Universal Design for Learning (UDL 3.0) framework is increasingly integrated into educational policy and practice.
• A gap existed in robust instruments to assess the implementation of UDL 3.0 through self-reported teaching practices.
• The study developed the Universal Design for Learning 3.0 Teacher Implementation Questionnaire (CID-DUA3).
• Preliminary evidence for the validity and reliability of the CID-DUA3 was obtained through an instrumental, non-experimental, cross-sectional study.
• The development involved a review of an initial 20-item version by a panel.
