determine the effectiveness of CTL, a team of evaluators has used
a variety of instruments and techniques to assess whether the CTL
web site is an effective vehicle to convey information about the scientific
processes behind climate variability over different timescales, and
whether it effectively communicates the relationship between climatic
variability and human civilization. For
the general evaluation a scope
of work (in pdf format) was developed to assist in guiding the
evaluators, Elizabeth Grassi and Heather Smith from the University
In order to conduct formal evaluation of human subjects, protocols and instruments were developed that were reviewed and authorized by the University of Colorado's Human Research Committee (HRC). In addition, informed consent forms were signed by students and, for minors, parental consent forms were required of all subjects involved in the evaluation. An online consent form was used by undergraduate students taking the online quiz.
