Based on findings from a large meta-data-based literature survey, this article is intended to provide a comprehensive synthesis of key features of China's music education system as seen through the lens of n = 116 major research studies, drawn from a total of N = 3,257 high-impact Chinese journal articles published during 2007 to 2019. The…

Bias poses a significant threat to the validity of research findings as well as practices and policies based on research. Reforms to academic publishing have been proposed and implemented in other fields to address bias in research. In this paper I review some sources of bias in research, some proposed areas of reform in academic publishing (e.g.,…

Valid, scientific research is critical for ascertaining the effects of instructional techniques on learners with disabilities and for guiding effective special education practice and policy. Researchers in fields such as psychology and medicine have identified serious and widespread shortcomings in their research literatures related to replication…

A recent report from the Reason Foundation argues for significant changes in how public education is organized and delivered in large cities. The report argues that city schools should move toward a "portfolio" of schools model. In such a model, the district does not necessarily operate schools, but instead focuses on closing low-performing…

The Education Trust research report "Stuck Schools" suggests a framework for identifying chronically low-performing schools in need of turnaround. The study uses Maryland and Indiana to show that some low-performing schools make progress while others remain stagnant. The report has four serious problems of reliability and validity,…

The new "Weighted Student Formula Yearbook 2009" from the Reason Foundation provides a simple framework for touting the successes of states and urban school districts that grant greater fiscal autonomy to schools. The report defines the Weighted Student Formula (WSF) reform extremely broadly, presenting a variety of reforms under the WSF umbrella.…

Schools should adopt reform programs on the basis of research, not ideology, checking for control groups, the number of participating schools, actual results, and independent resources. Two federal programs, the Comprehensive School Reform Demonstration Program and the 1998 Reading Excellence Act, stress adoption of research-based reforms. (MLH)

This document is part of a series of chapters described in SO 011 759. The chapter advocates the analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable) with maximum likelihood estimators (MLE) applied to log-linear rate models. Results from a Monte Carlo investigation of the impact…

This document is part of a series of chapters described in SO 011 759. Addressing the problems of studying change and the change process, the report argues that sociologists should study coupled changes in qualitative and quantitative outcomes (e.g., marital status and earnings). The author presents a model for sociological studies of change in…

This document is part of a series of chapters described in SO 011 759. The chapter examines the merits of four estimators in the causal analysis of event-histories (data giving the number, timing, and sequence of changes in a categorical dependent variable). The four procedures are ordinary least squares, Kaplan-Meier least squares, maximum…

This document is part of a series of chapters described in SO 011 759. This chapter reports the results of Monte Carlo simulations designed to analyze problems of using maximum likelihood estimation (MLE: see SO 011 767) in research models which combine longitudinal and dynamic behavior data in studies of change. Four complications--censoring of…

This document is part of a series of chapters described in SO 011 759. This chapter offers guidelines for studying change in dynamically interdependent variables, even when a model that ignores interdependence is estimated. Many sociological studies concern dynamically interdependent variables; for example, in a study of female employment, a…

Five sister reports published by the Friedman Foundation over the past two years have ignored the relevant research literature in asserting that private-school voucher programs can reduce the social costs of dropping out while increasing graduation rates. The reports are state-specific, targeting five different states. But each report follows a…

The document, part of a series of chapters described in SO 011 759, examines sociological research methods for the study of change. The advantages and procedures for dynamic analysis of event-history data (data giving the number, timing, and sequence of changes in a categorical dependent variable) are considered. The authors argue for grounding…

The document, part of a series of chapters described in SO 011 759, considers the problem of censoring in the analysis of event-histories (data on dated events, including dates of change from one qualitative state to another). Censoring refers to the lack of information on events that occur before or after the period for which data are available.…
