Survey interviewers can negatively affect survey data by introducing variance and bias into estimates. When investigating these interviewer effects, research typically focuses on interviewer sociodemographics with only a few studies examining the effects of characteristics that are not directly visible such as interviewer attitudes, opinions, and…

For hard-to-survey populations such as ethnic minorities and immigrants, increasing survey response rates is a crucial element of the fieldwork as these populations often show a higher likelihood of not participating compared with the native population. However, no study has so far compared different strategies for mobilisation within this group.…

Places to study at medical schools are scarce, which makes well-designed selection procedures employing criteria with predictive validity for good students and doctors necessary. In Germany, the pre-university grade point average (pu-GPA) is the main selection criterion for medical school application. However, this is criticised. According to a…

Identifying illicit behavior in survey research is inherently problematic, since self-reports are untrustworthy. We argue that fraudulent interviewers can, however, be identified through statistical deviance of the distributional parameters of their interviews. We document that a high proportion of the variation in the data is due to the…

Despite the fact that third parties are present during a substantial amount of face-to-face interviews, bystander influence on respondents' response behavior is not yet fully understood. We use nine waves of the German Family Panel "pairfam" and apply fixed effects panel regression models to analyze effects of third-party presence on…

This paper makes available to the broader educational community the instruments which have been originally designed and validated within the European project "CLIL for all: Attention to diversity in bilingual education" ("ADiBE") to determine how diversity is being catered to across a broad array of CLIL contexts in European…

Panel attrition is a major problem in long-term panel studies. While the design of the German National Educational Panel Study adult survey--combining biannual competency tests with regular face-to-face interviews--is highly innovative, such a design could raise respondent burden and thus potentially increase panel attrition and nonresponse bias.…

Computational thinking (CT) is seen as a key competence of the 21st century and different countries have started to integrate it into their compulsory school curricula. However, few indications exist on how to assess CT in compulsory school. This review analyses what tools are used to assess CT in European schools and which dimensions are…

The phenomenon of first impression is well researched in social psychology, but less so in the study of OSCEs and the multiple mini interview (MMI). To explore its bearing on the MMI method we included a rating of first impression in the MMI for student selection executed 2012 at the University Medical Center Hamburg-Eppendorf, Germany (196…

Interviews with scholars and experts are becoming more and more popular as e-learning materials. Yet how an interview video should be edited is mostly based on personal preference rather than on rigorous scientific research. Thus this study tested whether showing the interviewer in educational interview videos can affect the learning outcome. Two…

To reduce nonresponse bias in surveys, it has been suggested that researchers allocate additional fieldwork efforts to cases with low estimated response propensity. If these efforts are successful, nonresponse bias may be reduced by changing the variance of response propensities and hence the covariance between response propensities and variables…

In face-to-face interviews, accurate work by interviewers is crucial for ensuring high-quality survey data. In a field experiment, payment of interviewers, legitimation of falsification behavior, and respondents' willingness to participate were experimentally varied. The impact of these factors on interviewers' accuracy during fieldwork was…

Students participate during service learning courses in a service project, which fits to a community need and has a link to curricular content. Students have a chance while engaged in the service project to apply curricular content in community practice, where they gain insights into civic engagement activities. Empirical studies revealed the…

The main objective of the article is to illustrate how language ideologies and language management at the macro-level (state language policy), micro-level (in families) and meso-level (local communities) influence language change and the conceptualization of multilingualism of immigrants from Upper Silesia residing in Germany. Language biographies…

Quality management (QM) in teaching and learning has strongly "infected" the higher education sector and spread around the world. It has almost everywhere become an integral part of higher education reforms. While existing research on QM mainly focuses on the national level from a macro-perspective, its introduction at the institutional…
