Integrated in the
management process
of digital libraries


Accountability:
evidence of resources
spent
Effectiveness:
understanding basic
phenomena (as
information seeking)
Impact: as increased
learning, research,
dissemination

Outcomes

The ways in which library users are
changed as a result of their contact with
the library resources and programs (ARL

Outcomes based evaluation




Have audiences been sufficiently identified?
Are outcomes clearly written?
Are outcomes sufficient to describe what you
hope will happen?
Are data collection methods cost efficient?
Add: Do they provide the data you want and
need?

Who are they? (researchers, students, remote,
etc.? What is their context?)
How do they access the digital library?
(infomation seeking behviour, usability)
Why do they need the digital library? (activities,
expectations)
What type of resources do they need? (subject,
etc.)
What is the value of digital library? (impact,
outcomes, potential for community building)

Bad news

There is no single, easy to administer,
inexpensive, reliable, and valid approach
to evaluating interactive learning from
DLs.
A.M.Tammaro
University of Tbilisi, 5-15 July 2010
Good news
There are practical strategies for
documenting the development and
use of interactive learning, improving
it, and building a case for its effectiveness
and impact.
