Die kognitive Aktivierung ist eine der drei Basisdimensionen der Unterrichtsqualität (Klieme, 2019) und findet mittlerweile Eingang in international angelegte Modelle der Unterrichtsqualität (Bell et al., 2019; Charalambous & Praetorius, 2020). Die Dimension wurde bereits in einer Vielzahl von Studien, in verschiedenen Schulfächern und über verschiedene Schulformen hinweg empirisch untersucht (Praetorius et al., 2018). Dabei wurde die kognitive Aktivierung im Rahmen von Angebots-Nutzungs-Modellen (Fend, 2019) überwiegend als ein angebotsseitiges Potenzial der Lehrperson für die Schüler*innen operationalisiert (Denn et al., 2019). Hingegen ist bislang wenig darüber bekannt, wie kognitive aktivierende Impulse in der Interaktion zwischen Lehrperson und den Schüler*innen hergestellt und bearbeitet werden (Renkl, 2015; Vieluf, 2022).
In dieser Studie werden mithilfe der wissenssoziologisch fundierten Dokumentarischen Methode (Bohnsack, 2021) und ihrer Spezifizierung für die Analyse von Unterrichtsvideographien (Asbrand & Martens, 2018) die im Unterricht kommunizierten und handlungsleitenden, implizierten Wissensbestände rekonstruiert, die die Hervorbringung von kognitiver Aktivierung in der Interaktion bedingen. Es wird danach gefragt, wie kognitive Aktivierung in der Interaktion zwischen Lernenden und Lehrenden hergestellt und prozessiert wird. Als Datengrundlage dienen überwiegend Videos aus dem Mathematikunterricht der neunten Klasse zum Thema quadratische Gleichung aus der TALIS Videostudie Deutschland (Grünkorn et al., 2020).
Als Ergebnis ließen sich drei unterschiedlichen Formen der Aktivierung rekonstruieren. Typ I: Aktivierung zu Reproduktion ist durch ein instruktivistisches Verständnis der Lehrkraft geprägt, in dem aktivierende Impulse die Schüler*innen überwiegend zur Reproduktion von Wissen anregen. Typ II: Aktivierung zu unsystematischem Probieren wird durch ein vermittelndes Verständnis der Lehrperson bestimmt, bei dem die Impulse nicht an das bestehende Wissen der Schüler*innen anschließen und die Bearbeitung im Rahmen eines unsystematischen Probierens erfolgt. Typ III: Aktivierung zu fachlicher Konstruktion ist durch ein konstruktivistisches Unterrichtsverständnis der Lehrkraft gekennzeichnet und Impulse werden in einem ko-konstruktiven Prozess von den Schülern*innen in Zusammenarbeit mit der Lehrkraft bearbeitet.
Adaptive teaching is considered fundamental to teaching quality and student learning. It describes teachers’ practices of adjusting their instruction to students’ diverse needs and levels of understanding. Adaptive teaching on a micro level has also been labeled as contingent support and has been shown to be effective in one-to-one and small-group settings. In the literature, the interplay of teachers’ diagnostic strategies and instructional prompts aiming at tailored support are emphasized. Our study adds to this research by presenting a reliable measurement approach to adaptive classroom discourse in elementary science which includes a global index and the single indices of diagnostic strategies, instructional support, and student understanding. Applying this coding scheme, we investigate whether N = 17 teachers’ adaptive classroom discourse predicts N = 341 elementary school students’ conceptual understanding of “floating and sinking” on two posttests. In multilevel regression analyses, adaptive classroom discourse was shown to be effective for long-term student learning in the final posttest, while no significant effects were found for the intermediate posttest. Further, the single index of diagnostic strategies in classroom discourse contributed to long-term conceptual restructuring. Overall, teachers rarely acted adaptively which points to the relevance of teacher professional development.
In the process of life course transitions, relations between the self and the world transform, which can according to Hartmut Rosa be framed as resonance. This article focuses on the retirement transition and thus on the exit from gainful employment as one of the central spheres of our world relationship in late modernity. It raises the following questions: How do experiences of resonance change in the course of the retirement transition? Does the loss of gainful employment lead to disruptions or even the absence of resonance in terms of alienation? And which role do dimensions of social inequality, such as gender, income, education or mental health status play for resonance transformations in the transition to retirement? In terms of a reflexive mixed-methods design, this article combines quantitative panel data from the German Ageing Survey (2008–17) with a qualitative longitudinal study from the project “Doing Retiring” (2017–21). Our results show that the transition from work to retirement entails a specific “resonance choreography” that comprises a phase of disaffection (lack of resonance) at the end of one’s working life followed by a liminal phase in which people search for intensified experiences of resonance. We outline practices in which transitioning subjects seek out resonance, and the experiences they make within this process according to their social positions. We thereby find that the desire for resonance tends to be beyond intentional resonance management which manifests in products and services like coaching or wellness. In our conclusions, we discuss how resonance theory and retirement research/life course research can be fruitfully combined, but also highlight the methodological challenges the operationalization of resonance entails.
Lockdown measures including the closure of physical activity facilities were installed against the spread of the novel coronavirus in March 2020. The aim of the current online survey was to assess the lockdown effects on physical activity in German adults. We assessed physical activity using the European Health Interview Survey (EHIS) questionnaire. Pre-lockdown vs. lockdown differences were tested with the X2 test and the Student’s t-test for paired data. Predictor variables to explain compliance with physical activity recommendations were identified using a fixed effects binary logistic regression analysis. Data of 979 respondents were analyzed. Transport related and leisure time physical activity decreased (p < 0.001, d = 0.16; p < 0.001, d = 0.22, respectively). Compliance with physical activity recommendations decreased from 38.1% to 30.4% (chi2 [1, 1958] = 12.754, p < 0.001, V = 0.08). In the regression analysis, BMI (OR 0.944, 95% CI 0.909–0.981; p = 0.003), education (OR 1.111, 95% CI 1.021–1.208; p = 0.015), transport related (OR 1.000, 95% CI 1.000–1.000; p = 0.008) and leisure time physical activity (OR 1.004, 95% CI 1.003–1.004; p < 0.001), muscle strengthening (OR 5.206, 95% CI 4.433–6.114; p < 0.001), as well as the ‘lockdown vs. normal’ categorical variable (OR 0.583, 95% CI 0.424–0.802; p = 0.001) showed a contribution, while sex (p = 0.152), age (p = 0.266), work related physical activity (p = 0.133), and remote working (p = 0.684) did not. Physical activity declined in German adults, and should also be promoted in light of the emerging evidence on its protective effects of against COVID-19. Special attention should be given to muscle strengthening activities and groups with lower educational attainment.
Due to the increasingly heterogeneous trajectories of aging, gerontology requires theoretical models and empirical methods that can meaningfully, reliably, and precisely describe, explain, and predict causes and effects within the aging process, considering particular contexts and situations. Human behavior occurs in contexts; nevertheless, situational changes are often neglected in context-based behavior research. This article follows the tradition of environmental gerontology research based on Lawton’s Person-Environment-Interaction model (P-E model) and the theoretical developments of recent years. The authors discuss that, despite an explicit time component, current P-E models could be strengthened by focusing on detecting P-E interactions in various everyday situations. Enhancing Lawton’s original formula via a situationally based component not only changes the theoretical perspectives on the interplay between person and environment but also demands new data collection approaches in empirical environmental research. Those approaches are discussed through the example of collecting mobile data with smartphones. Future research should include the situational dimension to investigate the complex nature of person environment interactions.
The spread of the COVID-19 virus was met by a strict lockdown in many countries around the world, with the closure of all physical activity (PA) facilities and limitations on moving around freely. The aim of the present online survey was to assess the effect of lockdown on physical activity in Italy. Physical activity was assessed using the European Health Interview Survey questionnaire. A total of 1500 datasets were analyzed. Differences between conditions were tested with a chi2-based (χ2) test for categorical variables, and with the Student’s t-test for paired data. A fixed effects binary logistic regression analysis was conducted to identify relevant predictor variables to explain the compliance with World Health Organisation (WHO) recommendations. We found a substantial decline in all physical activity measures. Mean differences in walking and cycling metabolic equivalent of task minutes per week (METmin/week), respectively, were 344.4 (95% confidence interval (95% CI): 306.6–382.2; p < 0.001) and 148.5 (95% CI: 123.6–173.5; p < 0.001). Time spent in leisure time decreased from 160.8 to 112.6 min/week (mean difference 48.2; 95% CI: 40.4–56.0; p < 0.001). Compliance with WHO recommendations decreased from 34.9% to 24.6% (chi2 (1, 3000) = 38.306, p < 0.001, V = 0.11). Logistic regression showed a reduced chance (OR 0.640, 95% CI: 0.484–0.845; p = 0.001) to comply with WHO PA recommendations under lockdown conditions. Measures to promote physical activity should be intensified to limit detrimental health effects.
Drawing on the role of teachers for peer ecologies, we investigated whether students favored ethnically homogenous over ethnically diverse relationships, depending on classroom diversity and perceived teacher care. We specifically studied students’ intra- and interethnic relationships in classrooms with different ethnic compositions, accounting for homogeneous subgroups forming on the basis of ethnicity and gender diversity (i.e., ethnic-demographic faultlines). Based on multilevel social network analyses of dyadic networks between 1299 early adolescents in 70 German fourth grade classrooms, the results indicated strong ethnic homophily, particularly driven by German students who favored ethnically homogenous dyads over mixed dyads. As anticipated, the results showed that there was more in-group bias if perceived teacher care was low rather than high. Moreover, stronger faultlines were associated with stronger in-group bias; however, this relation was moderated by teacher care: If students perceived high teacher care, they showed a higher preference for mixed-ethnic dyads, even in classrooms with strong faultlines. These findings highlight the central role of teachers as agents of positive diversity management and the need to consider contextual classroom factors other than ethnic diversity when investigating intergroup relations in schools.
Physical activity counseling in primary health care is regarded as a useful complementary preventive and therapeutic measure and is advocated by leading public health institutions. This integrative review summarizes the available data on physical activity counseling in primary care in Germany. A systematic literature search in various databases (peer reviewed and grey literature) was carried out for quantitative and qualitative studies on physical activity counseling and use of “Exercise on Prescription”. The 25 studies included show a very high methodological diversity and, in some cases, considerable risks of bias, with limited comparability across studies. Counseling was provided in all studies by physicians. They report frequent physical activity counseling, which is partly confirmed and partly refuted by patient data. The use of “Exercise on Prescription” is at a very low level. Information on the frequency of physical activity counseling in Germany varies depending on data source and is sometimes contradictory. Our review provides a synthesis of various perspectives on routine physical activity counseling in primary care in Germany. Future studies using standardized and validated instruments in representative samples are needed to further knowledge on counseling and to be able to establish trends in prevalence. Strengthening the topics of physical activity and health and physical activity counseling in medical curriculum is strongly recommended.
Change ahead—emerging life-course transitions as practical accomplishments of growing old(er)
(2019)
With the aging of the "Baby Boomer" cohort, more and more adults are transiting from work into retirement. In public discourse, this development is framed as one of the major challenges of today's welfare societies. To develop social innovations that consider the everyday lives of older people requires a deeper theoretical understanding of the retiring process. In age studies, retiring has been approached from various theoretical perspectives, most prominently disengagement perspectives (retirement as the withdrawal from social roles and responsibilities) and rational choice perspectives (retiring as a rational decision based on incentives and penalties). Whereas, the former have been accused of promoting a deficient image of aging, the latter are criticized for concealing the socially stratified constraints older people experience. This paper proposes a practice-theoretical perspective on retiring, understanding it as a processual, practical accomplishment that involves various social practices, sites, and human, as well as non-human, actors. To exemplify this approach, I draw upon data from the project "Doing Retiring" that follows 30 older adults in Germany from 1 year before to 3 years after retirement. Results depict retiring as a complex process of change, assembled by social practices that are scattered across time, space, and carriers. Practice sequences and constellations differ significantly between older adults who retire expectedly and unexpectedly, for example through sudden job loss or illness. However, even among those who envisaged retiring "on their own terms," the agency to retire was distributed across the network of employers, retirement schemes, colleagues, laws, families, workplaces, bodies and health, and the future retiree themselves. Results identified a distinct set of sequentially organized practices that were temporally and spatially configured. Many study participants expressed an idea about a "right time to retire" embedded in the imagination of a chrononormative life-course, and they often experienced spatio-temporal withdrawal from the workplace (e.g., reduction of working hours) which entailed affective disengagement from work as well. In conclusion, a practice-theoretical perspective supports social innovations that target more than just the retiring individual.
