Abstract (english):
The present study investigates whether teacher perceptions of students' cognitive skills, their learning motivation, and their classroom behavior differ according to students' socioeconomic status, immigrant background, and gender. Data from N = 4746 German fourth graders and data from their parents and teachers were analyzed using structural equation modeling. Controlling for student achievement as measured in a standardized achievement test and student motivation as measured by student and parent reports, we found that teachers overestimated the cognitive skills of high-SES students and girls in comparison to those of low-SES students and boys. Similarly, teachers perceived high-SES students, students who are not from an immigrant background, and girls as having a higher learning motivation and as having more cognitive skills. Finally, we found that teachers' perceptions of students' learning motivation and classroom behavior mediated the relationship between student characteristics and cognitive skills as perceived by the teacher.

Abstract:
Personality is a relevant predictor for important life outcomes across the entire lifespan. Although previous studies have suggested the comparability of the measurement of the Big Five personality traits across adulthood, the generalizability to childhood is largely unknown. The present study investigated the structure of the Big Five personality traits assessed with the Big Five Inventory-SOEP Version (BFI-S; SOEP = Socio-Economic Panel) across a broad age range spanning 11-84 years. We used two samples of N = 1,090 children (52% female, Mage = 11.87) and N = 18,789 adults (53% female, Mage = 51.09), estimating a multigroup CFA analysis across four age groups (late childhood: 11-14 years; early adulthood: 17-30 years; middle adulthood: 31-60 years; late adulthood: 61-84 years). Our results indicated the comparability of the personality trait metric in terms of general factor structure, loading patterns, and the majority of intercepts across all age groups. Therefore, the findings suggest both a reliable assessment of the Big Five personality traits with the BFI-S even in late childhood and a vastly comparable metric across age groups. (DIPF/Orig.)

Abstract:
Aim: Personality traits and cognitive ability are well‐established predictors of academic performance. Yet, how consistent and generalizable are the associations between personality, cognitive ability, and performance? Building on theoretical arguments that trait-performance relations should vary depending on the demands and opportunities for trait expression in the learning environment, we investigated whether the associations of personality (Big Five) and cognitive ability (fluid intelligence) with academic performance (grades and tests scores) vary across school subjects (German and math) and across ability‐grouped school tracks (academic, intermediate, and vocational). Method: Multiple group structural equation models in a large representative sample of ninth‐grade students (N = 12,915) from the German National Educational Panel Study (NEPS). Results: Differential associations across school subjects emerged for cognitive ability, Emotional Stability, and Conscientiousness (math > German); and for Openness and Extraversion (German > math). Differential associations across school tracks emerged for cognitive ability, Conscientiousness (academic > intermediate > vocational) and Agreeableness (academic > intermediate > vocational). Personality traits explained more variation in academic performance in the academic than in the other tracks. Conclusion: Most trait-performance relations varied across subjects, tracks, or both. These findings highlight the need for more nuanced and context‐minded perspective on trait-performance relations. (DIPF/Orig.)

Abstract:
Older adults show relatively minor age-related decline in memory for single items, while their memory for associations is markedly reduced. Inter-individual differences in memory function in older adults are substantial but the neurobiological underpinnings of such differences are not well understood. In particular, the relative importance of inter-individual differences in the medio-temporal lobe (MTL) and the lateral prefrontal cortex (PFC) for associative and item recognition in older adults is still ambiguous. We therefore aimed to first establish the distinction between inter-individual differences in associative memory (recollection-based) performance and item memory (familiarity-based) performance in older adults and subsequently link these two constructs to differences in cortical thickness in the MTL and lateral PFC regions, in a latent structural equation modelling framework. To this end, a sample of 160 older adults (65-75 years old) performed three intentional item-associative memory tasks, of which a subsample (n = 72) additionally had cortical thickness measures in MTL and PFC regions of interest available. The results provided support for a distinction between familiarity-based item memory and recollection-based associative memory performance in older adults. Cortical thickness in the ventro-medial prefrontal cortex was positively correlated with associative recognition performance, above and beyond any relationship between item recognition performance and cortical thickness in the same region and between associative recognition performance and brain structure in the MTL (parahippocampus). The findings highlight the relative importance of the ventromedial prefrontal cortex in allowing for intentional recollection-based associative memory functioning in older adults. (DIPF/Orig.)

Abstract:
One key factor for the successful outcome of a Learning Analytics (LA) infrastructure is the ability to decide which software architecture concept is necessary. Big Data can be used to face the challenges LA holds. Additional challenges on privacy rights are introduced to the Europeans by the General Data Protection Regulation (GDPR). Beyond that, the challenge of how to gain the trust of the users remains. We found diverse architectural concepts in the domain of LA. Selecting an appropriate solution is not straightforward. Therefore, we conducted a structured literature review to assess the state-of-the-art and provide an overview of Big Data architectures used in LA. Based on the examination of the results, we identify common architectural components and technologies and present them in the form of a mind map. Linking the findings, we are proposing an initial approach towards a Trusted and Interoperable Learning Analytics Infrastructure (TIILA).

Abstract:
Das Begriffspaar 'Oberflächenmerkmale'/'Oberflächenstrukturen' und 'Tiefenmerkmale'/'Tiefenstrukturen' hat zunehmend EInzug in die Forschungsliteratur erhalten, soll es doch eine Brücke zur Verknüpfung von Lehren und Lernen schlagen. Im vorliegenden Beitrag wird nach einem Überblick zu den historischen Wurzeln das Verständnis der jeweiligen Begriffe zusammengefasst. Anhand von Arbeiten aus der (Fach-)Didaktik und der pädagogisch-psychologischen Unterrichtsforschung werden unterschiedliche Konzeptualisierung von Tiefenmerkmalen aufgezeigt und Befunde zur Lernwirksamkeit von Tiefenmerkmalen angeführt. Der Beitrag schließt mit Vorschlägen zur begrifflichen Schärfungen und diskutiert theoretische und empirische Desiderata bezogen auf das Begriffspaar. (DIPF/Orig.)

Abstract:
Background: Digital phenotyping promises to unobtrusively obtaining a continuous and objective input of symptomatology from patients' daily lives. The prime example are bipolar disorders, as smartphone parameters directly reflect bipolar symptomatology. Empirical studies, however, have yielded inconsistent findings. We believe that three main shortcomings have to be addressed to fully leverage the potential of digital phenotyping: short assessment periods, rare outcome assessments, and an extreme fragmentation of parameters without an integrative analytical strategy. Methods: To demonstrate how to overcome these shortcomings, we conducted frequent (biweekly) dimensional and categorical expert ratings and daily self-ratings over an extensive assessment period (12 months) in 29 patients with bipolar disorder. Digital phenotypes were monitored continuously. As an integrative analytical strategy, we used structural equation modelling to build latent psychopathological outcomes (mania, depression) and latent digital phenotype predictors (sleep, activity, communicativeness). Outcomes: Combining gold-standard categorical expert ratings with dimensional self and expert ratings resulted in two latent outcomes (mania and depression) with statistically meaningful factor loadings that dynamically varied over 299 days. Latent digital phenotypes of sleep and activity were associated with same-day latent manic psychopathology, suggesting that psychopathological alterations in bipolar disorders relate to domains (latent variables of sleep and activity) and not only to specific behaviors (such as the number of declined incoming calls). The identification of latent psychopathological outcomes that dimensionally vary on a daily basis will enable to empirically determine which combination of digital phenotypes at which days prior to an upcoming episode are viable as digital prodromal predictors.

Abstract (english):
This study examines the latent structure of the Rahim Organizational Conflict Inventory - II (ROCI-II) in several samples of secondary school students. Findings from earlier studies conducted in adult populations suggested that the instrument has a four- or five-factor structure; however, the exploratory factor analysis (EFA) in this study yielded a three-factor (integrating, dominating, avoiding) solution, with most of the items associated with a fourth factor (Obliging) failing to load as predicted. A confirmatory factor analysis (CFA) replicated the three-factor solution satisfactorily. A multiple-group CFA indicated that the ROCI-II showed invariant measurement properties in male and female students and corroborated the concurrent validity of the three-factor solution. The integrating factor was related positively to a measure of perspective taking but negatively to a measure of reluctance to participate. The avoiding factor was associated with a measure of reluctance to participate. We discuss the implications of the results for understanding the latent structure of the ROCI-II in adolescents.

Abstract:
Anhand der Befragungsdaten von 184 baden-württembergischer Kita-Fachkräften wird untersucht, welche Zusammenhänge zwischen dem Im- plementationserfolg einer Reformmaßnahme und den für die Implementation bedeutsamen individuellen und projektspezifischen Merkmalen bestehen. Dabei werden anhand eines Strukturgleichungsmodells die Beziehungen zwischen den individuellen Voraussetzungen der pädagogischen Fachkräfte und ihrer subjektiven Wahrnehmung einer erfolgreichen Implementation des Modellprojektes analysiert. Die Ergebnisse implizieren, dass die Wahrnehmung projektspezifischer Merkmale (relativer Vorteil, Kompatibilität und Komplexität) nicht unabhängig von den individuellen Vorausset- zungen der pädagogischen Fachkräfte (Einstellungen, Kenntnisse und berufl. Belastung) betrachtet werden sollte. Insbesondere die Einstellungen gegenüber schulvorbereitender Zusatzforderung weisen Zusammenhänge mit allen projektspezifischen Merkmalen auf. (DIPF/Orig.)
Abstract (english):
Analyzing survey data of 184 early childhood educators, this study ex- amines relationships between a successful implementation of an early education reform in kindergarten, and various individual and project-specific characteristics. Structural equation modeling is used to analyze the relationship between individual characteristics of the educators and their perceived implementation success. Results indicate that educators' views on project-specific characteristics can be explained by taking their individual characteristics (beliefs, knowledge and occupational stress) into account. Specifically, attitudes towards the enhancement of children's school readiness relate to all project-related criteria. (DIPF/Orig.)

Abstract (english):
Open informational ecosystems play a crucial role in fostering open educational resources (OER) and allow new opportunities to share and collaborate in the learning and teaching environment. Such ecosystems containing interoperable infrastructures and open interfaces aim at fulfilling user needs and fostering practices related to the concept of OER and the five user rights (5 R's). To fully embrace this role, those ecosystems need to be designed carefully. In this paper, we discuss implications for open informational ecosystems to fully comprise the concept of OER and related user needs. We carried out literature reviews to analyse recent aspects of the 5 R's in relation to user behaviour and infrastructures. We will introduce the results from these reviews and illustrate upcoming questions and challenges for the design of an ecosystem respecting the 5 R's conceptual ideas. With our recommendations, we aim at contributing to a better understanding of the concept of OER to improve ecosystem development and implement useful and user-friendly functions.
