The Long-Term Benefit of Video Modeling Examples for Guided Inquiry
(2019-10-01)
Inquiry-based learning can be considered a critical component of science education in which students can assess their understanding of scientific concepts and scientific reasoning skills while actively constructing new knowledge through different types of activity levels (Klahr and Dunbar, 1988; Bell et al., 2005; Hmelo-Silver et al., 2007; Mayer, 2007). However, engaging in inquiry activities can be cognitively demanding for students, especially those with low prior knowledge of scientific reasoning skills (reasoning ...

A structural topic model approach to scientific reorientation of economics and chemistry after German reunification
(2020-08-05)
The detection of differences or similarities in large numbers of scientific publications is an open problem in scientometric research. In this paper we therefore develop and apply a machine learning approach based on structural topic modelling in combination with cosine similarity and a linear regression framework in order to identify differences in dissertation titles written at East and West German universities before and after German reunification. German reunification and its surrounding time period is used because ...

A Survey on Cost Types, Interaction Schemes, and Annotator Performance Models in Selection Algorithms for Active Learning in Classification
(2021-12-14)
Pool-based active learning (AL) aims to optimize the annotation process (i.e., labeling) as the acquisition of annotations is often time-consuming and therefore expensive. For this purpose, an AL strategy queries annotations intelligently from annotators to train a high-performance classification model at a low annotation cost. Traditional AL strategies operate in an idealized framework. They assume a single, omniscient annotator who never gets tired and charges uniformly regardless of query difficulty. However, in ...

Who wants to learn harder? The relationship between conservatism and liberalism, desirable difficulties, and academic learning
(2022-01-04)
Previous work has shown that challenging learning strategies like desirable difficulties improve long-term learning. Nonetheless, because they might be regarded as strict and demanding learning strategies, they should not be perceived as positive by everyone. They should, however, fit conservative political attitudes since those are, among others, positively correlated with individuals’ need for order and structure as well as with challenging learning environments. Hence, we hypothesized conservative political attitudes ...

A study of 25 years of publication outputs in the German academic profession
(2022-01-11)
In the weak evaluation state of Germany, full professors are involved in the traditional social governance partnership between the state, and the self-governing higher education institutions (HEI) and disciplinary associations. Literature suggests that formal and informal governance could trigger changes in academics’ publication behavior by valorizing certain publication outputs. In the article, secondary data from three surveys (1992, 2007 and 2018) is used for a multi-level study of the evolution of academics’ ...

Mapping the field of research on African higher education: a review of 6483 publications from 1980 to 2019
(2020-11-16)
Following a global trend, higher education (HE) in Africa has also become a complex enterprise, potentially demanding specific expertise in higher education research. However, despite this, there is a dearth of analysis into the state of research on African HE. This paper seeks to fill this gap by mapping and analysing African HE research. We undertake a systematic review of 6483 articles and books focusing on African HE published from 1980 to 2019 in indexed and non-indexed journals and book-publishers. We particularly ...

Das Potenzial kooperativen Lernens ausschöpfen: Die Bedeutung der transaktiven Kommunikation für eine lernwirksame Zusammenarbeit
(2021-10-26)
Kooperatives Lernen eröffnet Chancen und birgt gleichzeitig Risiken für den Wissenserwerb. Der Beitrag arbeitet die Bedeutung der transaktiven Kommunikation als zentralen Wirkmechanismus für den genuinen Mehrwert kooperativen Lernens heraus. Unter transaktiver Kommunikation wird die fachinhaltliche Bezugnahme auf den Lernpartner verstanden, wobei niedrig-transaktive (z.B. paraphrasierende) von hoch-transaktiven (z.B. integrierenden) Äußerungen unterschieden werden. Es werden Bedingungen, unter denen sich transaktive ...

Are open-book tests still as effective as closed-book tests even after a delay of 2 weeks?
(2022-04-06)
The present work was conducted to re-examine the findings of Agarwal et al. (Applied Cognitive Psychology, 22(7), 861–876, 2008), which showed that both closed-book tests (with feedback) and open-book tests increased learning outcomes after 1 week compared to simple re-study of the same materials. However, contrary to often found benefits of retrieval practice—which should be more pronounced in closed-book tests—both test conditions proved to be similarly effective. As retrieval practice benefits increase with retention ...

Teachers’ emotional exhaustion before and during the COVID-19 pandemic: Neither emotional exertion nor vacation feeling
(2022-08-08)
In this paper, we use latent change models to examine the changes in in-service teachers’ emotional exhaustion before and during the COVID-19 pandemic. As a result of the pandemic, teachers are confronted with challenging tasks, which can lead to stress and burnout. Resultingly, teachers’ stress experiences have been examined in different studies. However, often the change in those experiences remains unclear. Against this background, we investigate longitudinally how the emotional exhaustion of a cohort of German ...
