I've written a number of books on that subject. My new book came out. It's titled Evaluation and is published by Prentice-Hall. No student should be without a copy. It gives practical advice about methods for evaluating a range of programs.
Organizations everywhere are interested in the outcomes of programs that they sponsor and run.
Researchers and officials are interested in when and how research and evaluation influence subsequent practice and policy. At least they should be interested. It's important stuff. Send e-mail to Rosalind Michahelles.
