RobotReviewer is a tool for automatically assessing the risk of bias in randomized controlled trials, but there is limited evidence of its reliability. We evaluated the agreement between RobotReviewer and humans regarding the risk of bias assessment based on 1955 randomized controlled trials. The risk of bias in these trials was assessed via two…

Randomized clinical trials underpin evidence-based clinical practice, but flaws in their conduct may lead to biased estimates of intervention effects and hence invalid treatment recommendations. The main approach to the empirical study of bias is to collate a number of meta-analyses and, within each, compare the results of trials with and without…

Situational Teaching plays a crucial role in English classroom teaching in Chinese Primary Schools; hence the relevant research prospers simultaneously. This study is devoted to reveal the research characteristic on English Situational Teaching in Primary Schools in the past 6 years. Result of contrastive analysis and survey of the essays…

This "What Works Clearinghouse Procedures and Standards Handbook (Version 3.0)" provides a detailed description of the standards and procedures of the What Works Clearinghouse (WWC). The remaining chapters of this Handbook are organized to take the reader through the basic steps that the WWC uses to develop a review protocol, identify…

This study was designed to look for patterns of parental behavior by assessing styles of child rearing in a novel way--through responses on an interactive computer program simulating an average day in the life of a mother and a preschooler. Presented to each subject (39 mothers of preschoolers and a control group of non-mothers) were 30 common…

There is a need for clarity regarding different research strategies in order to assess the relative contribution of each. Using the framework of the Facet Design Technique (FDT) for problem structuring, eight general research strategies are identified as they relate to measurement fidelity, representativeness of units, and treatment…

Eleven indexes of rurality and their effect on the classification of Michigan's 83 counties were investigated. The indexes were based on different concepts of rurality: (1) percent of employment in agriculture, fishing, and forestry; (2) population density and distance to urban centers; and (3) economic conditions. Index rankings were compared to…

Recent findings in the literature on child abuse have been inconsistent and often contradictory, perhaps in part because most researchers treat child abuse as a homogeneous psycho-social phenomenon and commit the error of group averaging. One methodology which deals directly with the problem of homogeneity error is the typology approach. This…

This study reports various aspects of the analyses carried out on the longitudinal data reported in a previous study (PS 007 345) for determining the general growth patterns and growth velocity of mental and motor development. Preliminary analyses focused on the selection of the growth curve, its evaluation in the 208 individual cases, and the…

A cost-benefit and system-analysis approach was utilized in an effort to study the quality of education in the State of Kentucky. This first report of that 2-year study relates: background information problems of measuring quality; methodology employed; rankings of the 197 school districts; and the input, output, and process variables. Two…

This paper provides a critical review of the state of the comparative study of educational innovation and reform and proceeds to identify a number of theoretical issues and challenges on which further comparative work is likely to shed additional light. The review portion of the paper deals with the heuristic, political, and theoretical utility of…

To evaluate the accuracy of the 1970 census' occupational classification system, a comparison was made between that year's responses to census questions and the replies by the same population group to the 1972 Postcensal Manpower Survey (PMS). Each of these questionnaires relied on a different methodology; in the PMS the respondent classified…
