A growing body of literature suggests that neurodiverse learners may possess assets that are highly desirable within engineering disciplines. Even so, despite the potential of neurodiverse individuals to contribute to innovation in science and engineering, neurodiverse students, such as those with attention deficit hyperactivity disorder (ADHD), autism, or dyslexia, remain highly underrepresented in engineering majors. We argue that the predominant perception of neurodiversity as a disability limits the participation of neurodiverse students in engineering education, ultimately impacting the diversity and creativity of the engineering workforce. In this paper, we review the emerging literature on neurodiversity that takes a social ecology approach and moves away from deficit-based models. We then describe the potential benefits and challenges of neurodiversity in the context of engineering education. We conclude with a concept analysis of how a strengths-based perspective of neurodiversity may be integrated within engineering education in particular, as well as in higher education overall, as we present our vision for a transformative education system that moves beyond mere accommodation of learning differences and empowers all students to leverage their unique strengths. In presenting a strengths-based approach to neurodiversity, we aim to contribute to a paradigm shift that transforms how university faculty and staff understand and perceive neurodiversity, improves the educational experiences of neurodiverse students in higher education and enhances the creativity of the engineering workforce.more » « less

The rate and pathway of ferrihydrite (Fh) transformation at oxic conditions to more stable products is controlled largely by temperature, pH, and the presence of other ions in the system such as nitrate (NO3–), sulfate (SO42–), and arsenate (AsO43–). Although the mechanism of Fh transformation and oxyanion complexation have been separately studied, the effect of surface complex type and strength on the rate and pathway remains only partly understood. We have developed a kinetic model that describes the effects of surface complex type and strength on Fh transformation to goethite (Gt) and hematite (Hm). Two sets of oxyanion-adsorbed Fh samples were prepared, nonbuffered and buffered, aged at 70 ± 1.5 °C, and then characterized using synchrotron X-ray scattering methods and wet chemical analysis. Kinetic modeling showed a significant decrease in the rate of Fh transformation for oxyanion surface complexes dominated by strong inner-sphere (SO42– and AsO43–) versus weak outer-sphere (NO3–) bonding and the control. The results also showed that the Fh transformation pathway is influenced by the type of surface complex such that with increasing strength of bonding, a smaller fraction of Gt forms compared with Hm. These findings are important for understanding and predicting the role of Fh in controlling the transport and fate of metal and metalloid oxyanions in natural and applied systems.more » « less
