Early career researchers are faced with the expectation of their scientific communities to conduct independent research, which is reflected in the development of independent new research lines. This change must take place under conditions that vary between national career systems. Case studies for a chair system (Germany) and two tenure systems,…

The article is a critical sociological analysis of current transnational practices on creating comparable measurements of dropout and completion in higher education and the consequences for the conditions of scientific knowledge production on the topic. The analysis revolves around questions of epistemological, methodological and symbolic types…

Survey research is prevalent among many professional fields. Both cost effective and time efficient, this method of research is commonly used for the purposes of gaining insight into the attitudes, thoughts, and opinions of populations. Additionally, because there are several types of survey research designs and data collection instruments, the…

Including all children in large-scale educational studies is a pressing concern. Omitting certain types of children from studies can lead to skewed findings that promote inaccuracies about learning levels or educational quality. Increasingly, assessments are a method for investigating the quality of education systems, but national assessments are…

Regression discontinuity design (RD) has been widely used to produce reliable causal estimates. Researchers have validated the accuracy of RD design using within study comparisons (Cook, Shadish & Wong, 2008; Cook & Steiner, 2010; Shadish et al, 2011). Within study comparisons examines the validity of a quasi-experiment by comparing its…

In this article, I provide a conceptually oriented overview of Bayesian approaches to statistical inference and contrast them with frequentist approaches that currently dominate conventional practice in educational research. The features and advantages of Bayesian approaches are illustrated with examples spanning several statistical modeling…

This chapter discusses the main challenges in higher education comparative research, focusing on cross-national forms of comparison and presenting examples from European research. The first part stresses the importance of constructing concepts which can travel across countries. This part identifies the different vertical levels of comparison…

The purpose of this study was to analyze and compare recent research papers on foreign language education in Turkish context with those published in international context to shed light on researchers and policy makers for future studies. This study filled a gap in this field and also aimed to increase the rate of acceptance of research papers…

The last decades have seen the completion of an increasing number of qualitative comparative research projects on teaching. Challenges and benefits which might arise from a qualitative international comparative research design have been considered. However, very little has been published on challenges and benefits which may arise from using…

The use of "radar charts" is an increasingly popular way to present spatial data in a visually interesting format. Some authors recommend using "filled radar charts" to compare the performance of observational units. Filled radar charts are not appropriate for such comparisons because the size of the area within the polygon is not invariant to the…

Background: The efficacy of three dietary treatments for ADHD has been repeatedly tested in randomized controlled trials (RCTs). These interventions are restricted elimination diets (RED), artificial food colour elimination (AFCE) and supplementation with free fatty acids (SFFA). There have been three systematic reviews and associated…

The article discusses comparative organizational studies, focusing on change in higher education institutions, and in particular (but not only) on studies that compare organizations in different national settings. It first presents and discusses different approaches to comparison based on a couple of typologies that have been developed to identify…

Despite the value of the comparative perspective for the study of higher education is widely recognised, there is little consensus about the specific methodological approaches. Quantitative tools outlined their relevance for addressing comparative analyses since they are supposed to reducing the complexity, finding out and graduating similarities…

Missing data are a common occurrence in survey-based research studies in education, and the way missing values are handled can significantly affect the results of analyses based on such data. Despite known problems with performance of some missing data handling methods, such as mean imputation, many researchers in education continue to use those…

Weiss, Keith, Zhu, and Chen (2013a) and Weiss, Keith, Zhu, and Chen (2013b), this issue, report examinations of the factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) and Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV), respectively; comparing Wechsler Hierarchical Model (W-HM) and…
