This paper reviews literature on the rationale, challenges, and recommendations for choosing a nonequivalent comparison (NEC) group design when evaluating intervention effects. After reviewing frequently addressed threats to validity, the paper describes recommendations for strengthening the research design and how the recommendations were…

This study develops a three-stage model of the question-answering process and investigates several potential sources of extraneous variability. Discussion includes implications of findings concerning what it means to "use" library materials and services, adverbs used as response category labels, and subject's responses as predictors of…

The hypothesis that conventional approaches to evaluating contaminants in performance appraisal overlook important individual ratee effects was examined. A rating form was developed that consisted of the following dimensions and behaviors: warmth; guided discourse or indirect teaching methods; control of subject matter; enthusiasm and reinforcing;…

Conducting observational research in a cross-cultural context invokes a unique set of difficulties. This paper describes sources of bias and threats to validity that are specific to cross-cultural research. It describes problems of cross-cultural research designs for descriptive studies, comparative research, and experimental research and outlines…

Discusses the importance of validating research data from questionnaires, exploring the difficulties presented in an attempt to validate questionnaire data regarding students' attitudes toward learning English in Japan. (Author/CB)

Researchers conducted surveys of public attitudes in two Tennessee school systems in 1984-85 and 1985-86. Although interested in the survey results, one purpose of the researchers was to determine some inexpensive and relatively simple survey procedures. The researchers sought--through several pilot studies--to identify an efficient, parsimonious…

This article is the first of a research methods series dedicated to getting good results from survey research. In this series, "good results" is a stenographic term used to define surveys that yield accurate and meaningful information decision makers can use with confidence to identify current practices that merit continuation and to create or…

Describes issues which are common to all research methodologies and some that were unique to the assessment techniques used in the Child Development Project (CDP) in San Ramon, California. Looks at the limited amount of time given assessments and the "fluid" nature of measurements. Notes that CDP issues involved observations,…
