Comparing and Improving the Accuracy of Nonprobability Samples: Profiling Australian Surveys
Full text linkThere has been a great deal of debate in the survey research community about the accuracy of nonprobability sample surveys. This work aims to provide empirical evidence about the accuracy of nonprobability samples and to investigate the performance of a range of post-survey adjustment approaches (calibration or matching methods) to reduce bias, and lead to enhanced inference. We use data from five nonprobability online panel surveys and compare their accuracy (pre- and post-survey adjustment) to four probability surveys, including data from a probability online panel. This article adds value to the existing research by assessing methods for causal inference not previously applied for this purpose and demonstrates the value of various types of covariates in mitigation of bias in nonprobability online panels. Investigating different post-survey adjustment scenarios based on the availability of auxiliary data, we demonstrated how carefully designed post-survey adjustment can reduce some bias in survey research using nonprobability samples. The results show that the quality of post-survey adjustments is, first and foremost, dependent on the availability of relevant high-quality covariates which come from a representative large-scale probability-based survey data and match those in nonprobability data. Second, we found little difference in the efficiency of different post-survey adjustment methods, and inconsistent evidence on the suitability of ‘webographics’ and other internet-associated covariates for mitigating bias in nonprobability samples
Measuring Students‘ Reading Behavior with an Ambulatory Assessment – A Field Report on a Smartphone-Based Reading Diary Study
Full text linkIn prior research, reading behavior was predominantly measured using either a questionnaire, which is economical and easy to implement but imprecise, or paper-pencil diaries that document reading behavior quite accurately, but which are time consuming and costly. The present study aims to introduce and evaluate a precise and easy to implement measure of reading behavior, namely a reading diary app in which participants can record their reading behavior on a smartphone. To evaluate the development procedure, the first research question asked whether data gathered with the app is of high quality (e.g., reliability). The second research question asked how reading time recorded via the app is related to reading time assessed via different retrospective questionnaires. n = 31 German university students recorded their reading activities for 14 days. Different approaches were applied to estimate the data quality and reliability and yielded satisfactory results. Participants reported more time spent reading daily on the retrospective questionnaire than when recording their reading time using the app. The correlation between reading diary app data and questionnaire data was medium in size. Our findings are discussed in the light of future directions for reading research and the use of ambulatory assessments
Measuring Congruence Between Voters and Parties in Online Surveys: Does Question Wording Matter?
Full text linkCongruence on policies between political parties and voters is a frequently assumed requirement for democracy. To be able to study this, we should be able to calculate accurate and precise measures of policy congruence in political systems. This could then tell us more about the political system we study, and the “distances” that exist between parties and voters on either issues or broader ideological dimensions. Here, I draw on experimental data from a Voting Advice Application to show that the wording of the issues can influence the degree of congruence one measures. Yet, this comes with the complication that this influence depends on the type of issue, the characteristics of the voters themselves, and the party the congruence is calculated with. These findings should serve as a warning for those who aim to measure congruence that even minor changes in question-wording can (but do not have to) cause relatively large changes in congruence, especially when many parties are involved and the differences between the congruences are small
Das Tandemseminar „Der Widerstand gegen den Nationalsozialismus in der deutschen Wikipedia“: ein Lehrexperiment mit forschendem Lernen im Open-Science-Format
Full text linkDas Seminar „Der Widerstand gegen den Nationalsozialismus in der deutschen Wikipedia“, das zur einen Hälfte von Angela Borgstedt, Leiterin der Forschungsstelle Widerstand, in der Zeitgeschichte und zu anderen Hälfte von mir in der germanistischen Linguistik angeboten wurde, war eine experimentelle Lehrveranstaltung, ein interdisziplinäres Tandem-Seminar und ein Seminar mit forschendem Lernen im Open Science-Format. Das Seminar bzw. die zwei Seminare wurden im Frühjahr-Sommer-Semester 2022 als Hauptseminare im Bachelor für Studierende der Geschichte und Studierende der germanistischen Linguistik an der Universität Mannheim durchgeführt. Dank einer Förderung vom Open Science Office der Universität Mannheim war es möglich, innerhalb des Seminars auch bezahlte öffentliche Veranstaltungen, nämlich zwei Vorträge, einen Workshop und eine Lesung, für die Studierenden anzubieten. Beide Seminare des Tandems waren übervoll, das Interesse der Studierenden war groß
Enseignement pluriel et assurance qualité ? Réflexions à propos des innovations éducatives à l’exemple de l’intercompréhension en Sarre
Full text linkDer vorliegende Beitrag skizziert die Entwicklung sprachenvernetzenden Unterrichtens im Bereich des interkomprehensionsbasierten Mehrsprachenlehrens und -lernens am Beispiel des Saarlandes. Anhand eines zusammenfassenden Blicks auf Ergebnisse und Erfahrungen von mehr als zehn Jahren theoretischer und praktischer Forschung wird die enge Verbindung zwischen Forschung, praktischer Umsetzung und konzeptioneller und theoretischer Entwicklung beleuchtet – Faktoren, die sich in einem integralen Prozess gegenseitig verstärken. Anschließend richten wir unseren Blick auf die Frage, inwieweit die an der Universität des Saarlandes entwickelten Aktivitäten als Beitrag zur Entwicklung der Qualitätssicherung der sprachlichen Bildung im Saarland angesehen werden können.This article outlines the development of multilingual education in the field of intercomprehension-based teaching and learning, with a spotlight on Saarland. After a summarizing look at the results and experiences of more than ten years of theoretical and practical research, the close connection between research, practical implementation, and conceptual and theoretical development is highlighted – factors that reinforce each other in an integral process. We then turn our attention to the question of the extent to which the activities developed at Saarland University can be seen as a contribution to the development of quality assurance in language education in Saarland
