Future Oriented Colleges and Universities

The AIR model we describe in this article is a practical framework for cultivating reflective inquiry into ethical issues that students, faculty, and administrators experience in the midst of busy daily lives and encounter in classroom discussions in a discipline field. The model is highly adaptable to academic and workplace settings and enables students to clarify and refine their ethical thinking and make more caring, compassionate, and respectful choices. Quantitative and qualitative assessment indicates that students who use AIR as an organizing framework become more empowered and competent to engage in reflective ethical inquiry.

Measuring self-determination in Norwegian students: adaptation and validation of the AIR Self-Determination Scale

This study describes the adaptation and validation of the American Institute for Research (AIR) Self-Determination Scale for use in Norwegian research and education. The study contributes to the field by enabling reliable assessment of self-determination of Norwegian students with intellectual disability. The operational equivalence of the construct of self-determination in American and Norwegian culture were examined. The article further describes the adaptations that were made to the scale to ensure its fitness for intended use. Psychometric reliability (Cronbach’s α and test-retest reliability) was tested on 121 students, and the underlying structure of the scale was examined by means of principal component analysis. The adapted version of the questionnaire (AIR-S-NOR) shows respectable psychometric properties. Suggestions for how the AIR-S-NOR can be used in future research and educational practices are presented.
