All projects are required to have an outside, independent evaluator. This person may conduct the formative evaluation and certainly conducts the summative evaluation activities. Often this involves visiting the project and the participants on a regular basis, making observations, and making sense of what is seen. Frequently other data is collected on use and achievement. These evaluator reports are a critical component of all education grants.
Every project has such data but it is only available to the public when the grant is completed.
A common requirement is that the grant staff make public presentations of their findings, usually at conventions such as the American Educational Research Association. Unfortunately, once the final report is submitted by the project and read by the project director, the report and data are archived and seldom viewed again. We need a better way to disseminate findings and we are hoping that extended NSF web pages will make this information more public. One is that as an economic advantage, technology is a failure. Most NSF projects as well the discussion on many listservs report that the development time is substantial for each course.
