Evaluation Plan:  

Researchers who borrow devices will be asked to complete evaluations to
identify the strengths, weakness, and value of the Device Library.

These three short evaluations are related to:

  1. the researcher-generated questions submitted before borrowing the device
  2. the borrowing experience and impact
  3. the long-range impact (sent 6 months after device return)
