The use of video surveillance footage presents a new possibility in educational research as a reliable and valid source of learning and teaching activities in classrooms. However, the unique nature of surveillance footage requires different approaches and poses distinctive challenges in utilizing it in research, yet no methodological guides are…

Because health behavior is often concerned with dynamic constructs, a longitudinal approach to measurement is needed. The Longitudinal Guttman Simplex (LGS) is a measurement model developed especially for dynamic constructs exhibiting cumulative, unitary development measured longitudinally. Data from the Television Smoking Prevention Project, a…

Surveys 33 developmental studies using 12 different locus of control scales in the effort to learn how perceived internal control changes with age. A few studies show developmental declines in perceived control, about half show consistent developmental increases, and about half show mixed results or no significant developmental differences.…

An issue facing researchers who study very select populations is how to obtain reliability estimates on instruments. When the populations and resulting samples are very small and select, the ability to obtain reliability estimates becomes very difficult. As a result, many researchers ignore reliability concerns and forge ahead with data…

Findings of a study that determined the ways in which practicing administrative course developers utilize instructional design activities in their design projects are presented in this paper. A survey was administered to 30 participants in a training and development group within a large organization and mailed to 43 other practicing instructional…

Error profiles for the Fall Enrollment Survey of the Higher Education General Information Survey (HEGIS) were developed as part of an assessment of the quality of survey data. Three statistics were of particular interest: the count of full-time equivalent students, the breakdown by race/ethnicity, and the count of unclassified students. Attention…

The project documented in this report identified barriers researchers encounter in gaining access to--i.e., identifying, acquiring, handling, and using--published information and measured the seriousness of the more significant barriers. Fifty-one barriers were identified, and a method of measuring their seriousness was developed. Thirty of the…

Based on the premise that the major emphasis in population education should be on the development of problem analysis and values clarification, the manual offers guidelines for program evaluation. It consists of eight chapters. Chapter I discusses the nature of educational research and in-school and out-of-school population programs. Chapter II…
