Table 2-4 shows the distribution of the author’s background by type of study. Across the four types of evaluation studies reviewed, 40 percent were done by authors internal to the curriculum project studied. If the study had more than one author, the authors were considered internal if one or more were related to the project (e.g., curriculum developer, curriculum project’s evaluator, and curriculum staff). Twenty-two percent of the studies were conducted by graduate students, who may be internal to the project because often they are the curriculum developer’s graduate students who perform the research studies. Because the relationship of the graduate student to the curriculum project is not always known, it can only be definitively stated that all authors were external to the project in 32 percent of the studies. The relationship of the author to the curriculum project is unknown in 6 percent of studies.
