Can you explain Stages 1, 2, and 3 of knowledge development?
One of the primary goals of scientific research is to create or develop new knowledge. However, all knowledge development is not the same. Many scholars and institutes, including National Institute on Disability and Rehabilitation Research (NIDRR), have discussed knowledge development stages that are typically generated by scientific research.
For NIDRR, these "stages relate to the types of objectives and end products that grantees are expected to pursue. These stages include: (1) discoveries and descriptions; (2) theories, measures, and methods; and (3) interventions, products or devices, and environmental adaptations".
NIDRR suggests that the stages of knowledge development are interrelated. Typically "research begins with significant discoveries (stage one) and moves through theory, measure, and method development (stage two) ultimately to enable the development of effective new and improved interventions, products and devices, and environmental adaptations (stage three). In this context, a product may be a new device or technique. An adaptation may include methods to improve physical, behavioral, or virtual environments." More information about the stages of knowledge development are included in the NIDRR 2005-2009 Long Range Plan.
