Peer reviewedSiegler, Robert S.; Chen, Zhe – Cognitive Psychology, 1998
Trial-by-trial strategy assessments and a microgenetic design were used to examine the learning of rules for solving balance scale problems by 70 4- and 70 5-year olds. Developmental differences in learning that emerged seemed to reflect both distal and proximal influences. Encoding and initial rule use were related to different learning process…

Peer reviewedLederman, Norman G.; Niess, Margaret L. – School Science and Mathematics, 2001
Focuses on and discusses the common knowledge concerning research design and the statistical analysis of data. (Author/ASK)

Henke, Robin R.; Kaufman, Phillip; Broughman, Stephen P.; Chandler, Kathryn – Education Statistics Quarterly, 2000
Examines differences in the design and execution of two surveys: the 1996 National Household Education Survey (NHES) and the 1994 October Current Population Survey (CPS). These differences may have contributed to disparate estimates of the number and proportion of home-schooled children. Discusses implications for survey research and home…

Peer reviewedMason, Greg – Canadian Journal of Program Evaluation/La Revue canadienne d'evaluation de programme, 1996
This article reviews issues in questionnaire design beyond the creation of standardized questions and basic data collection rules. The use of magnitude scales, the application of decision theory, and the use of a questionnaire framework that replicates how choices are made by respondents are among the new design approaches discussed. (SLD)

Peer reviewedFink, Edward J.; Gantz, Walter – Journalism and Mass Communication Quarterly, 1996
Examines 10 variables in content analyses of 245 journal articles from the social scientific, interpretive, and critical traditions. Finds that researchers conform highly to expectations associated with ontology, epistemology, data collection, and data analysis, but less so with theory, hypotheses, sampling, verification, and generalization.…

Peer reviewedMathison, Sandra; Meyer, Tricia R.; Vargas, Juan D. – New Directions for Evaluation, 1999
Describes verbal protocols as a useful tool for evaluating computer hardware and software, especially if informed by activity theory. Such protocols cannot, however, stand alone in a thorough evaluation design. (Author/SLD)

Peer reviewedRheinheimer, David C.; Penfield, Douglas A. – Journal of Experimental Education, 2001
Studied, through Monte Carlo simulation, the conditions for which analysis of covariance (ANCOVA) does not maintain adequate Type I error rates and power and evaluated some alternative tests. Discusses differences in ANCOVA robustness for balanced and unbalanced designs. (SLD)
Descriptors: Analysis of Covariance, Monte Carlo Methods, Power (Statistics), Research Design
Peer reviewedKlockars, Alan J.; Beretvas, S. Natasha – Journal of Experimental Education, 2001
Compared the Type I error rate and the power to detect differences in slopes and additive treatment effects of analysis of covariance (ANCOVA) and randomized block designs through a Monte Carlo simulation. Results show that the more powerful option in almost all simulations for tests of both slope and means was ANCOVA. (SLD)

Peer reviewedOakes, J. Michael; Feldman, Henry A. – Evaluation Review, 2001
Describes and compares useful and unified power formulas for analysis of covariance and change-score analyses, indicating the implications of each for sample size requirements. Contains practical recommendations for evaluations and outlines a simple spreadsheet approach. (SLD)

Peer reviewedColl, Richard K.; Chapman, Richard – Asia-Pacific Journal of Cooperative Education, 2000
Both quantitative and qualitative methodologies have advantages and disadvantages. Choice of methodology should be determined by the nature of the research objectives. Cooperative education researchers should consider qualitative or combined-methodology inquiries including interviews and action research. (SK)

Alex; Mossholder, Andrew; Osher, Trina; Petti, Theodore; Prentice, Ernest; Vitiello, Benedetto; Wells, Karen – Journal of the American Academy of Child and Adolescent Psychiatry, 2004
Objective: The use of placebo in the pediatric age group has come under increasing scrutiny. At the 2002 Annual Meeting of the American Academy of Child and Adolescent Psychiatry, the Academy's Workgroup on Research conducted a research forum. The purpose was to identify challenges and their solutions regarding the use of placebo in randomized…

Peer reviewedLebowitz, Barry D. – Gerontologist, 2004
This article, based on a Lawton Award Lecture, addresses the subject of the need to enhance the evidence base in our field in order to influence processes of policy development. Four issues are identified as critical to this: theory-driven targets of public health significance, use of appropriate and sophisticated approaches to research design and…

Direct linkBell, Philip – Educational Psychologist, 2004
Over the past decade, design experimentation has become an increasingly accepted mode of research appropriate for the theoretical and empirical study of learning amidst complex educational interventions as they are enacted in everyday settings. There is still a significant lack of clarity surrounding methodological and epistemological features of…

Hafer, Carolyn L.; Begue, Laurent – Psychological Bulletin, 2005
M. J. Lerner (1980) proposed that people need to believe in a just world; thus, evidence that the world is not just is threatening, and people have a number of strategies for reducing such threats. Early research on this idea, and on just-world theory more broadly, was reviewed in early publications (e.g., M. J. Lerner, 1980; M. J. Lerner & D. T.…

Logemann, Jeri A. – Journal of Communication Disorders, 2004
Recent importance placed upon efficacy research has spawned the development of the Communication Sciences and Disorders Clinical Trials Research Group (CSDRG). This group, funded by the National Institutes of Health (NIH), was organized by the American Speech Language and Hearing Association to address the need for more treatment efficacy research…
