Problems and Techniques in Achieving Both Ecological and Population Validity in Educational Research.
Sulkin, Howard A.; And Others
Some of the requirements and consequences of rigorous and valid educational evaluation research are explored in terms of problems in achieving two types of external validity, population and ecological. The former refers to the generalizability of inferences to subjects not included in a study, while the latter is concerned with the "environment" under which the same results can be expected. A research model which emphasizes the use of a well-controlled and well-defined stimulus situation and thus facilitates unambiguous determination of the relationship between stimulus and response is considered. A recent study in which some social-psychological problems arose directly related to constraints involved in achieving ecological and population validity is examined in detail. (CK)
