Erstsprachförderung bei Migrantenkindern in Kindergärten: Wirkungen auf phonologische Bewusstheit, Wortschatz sowie Buchstabenkenntnis und erstes Lesen in der Erst- und Zweitsprache

Zusammenfassung: Mit einer quasi-experimentellen Längsschnittstudie wurde bei Migrantenkindern im Kindergarten untersucht, welche Bedeutung die Förderung der Erstsprache für das Beherrschen der Erst- und Zweitsprache hat. Während zwei Jahren wurde die Sprachförderung in der Erst- und Zweitsprache mittels gleicher Themen und Geschichten im Unterricht koordiniert. Zudem wurden die Eltern dazu angeleitet, ihren Kindern zu Hause drei Mal pro Woche Geschichten in der Erstsprache vorzulesen oder Hörbücher in der Erstsprache abzuspielen. Die aufwändige Intervention hatte weder auf die Entwicklung der Sprachkompetenzen in der Erstsprache noch auf die Entwicklung der Sprachkompetenzen in der Zweitsprache Deutsch statistisch signifikante Auswirkungen. Die aufgrund der Interdependenzhypothese von Cummins erwarteten Transfereffekte zwischen Erst- und Zweitsprache ließen sich nur sehr beschränkt nachweise

Smudge and mirrors: representations of First Nations knowledge in the Sudbury Catholic District School Board

This research seeks to explore the understanding of, and representation of Indigenous knowledges within elementary schools within the Sudbury Catholic District School Board. Moreover, the research seeks to examine the perceived barriers that are faced by educators in the representation of Indigenous knowledges within elementary urban schools. The research will conclude by exploring some recommendations on reshaping educational institutions to better incorporate Indigenous content and knowledge within elementary schools. This research confirms what First Nations parents, communities and students already know, western systems of education are continuing to fail First Nations students and by extension First Nations communities as they continue to perpetuate colonial approaches to the delivery of education for First Nations students.Master of Indigenous Relations (MIR

Who Likes to be Reachable? Availability Preferences, Weak Ties, and Bridging Social Capital

In this paper, we investigate how individual differences in availability preferences are related to (1) self-reported quality of interaction with strong and weak ties and (2) perceptions of bridging social capital. We employed experience sampling methods and collected data over the course of two weeks—combined with surveys at baseline and endpoint, from a random sample of college students (N = 154). We show that individuals who prefer to be more available to others report more rewarding interactions with weak ties. Furthermore, we demonstrate how the quality of weak tie interactions mediates a positive relationship between availability preferences and bridging social capital. We conclude by discussing the relationships between availability, interaction quality, and bridging social capital. We propose availability preferences as a key construct to be considered in future research

No loss, no gain? COVID-19 school closures and Swiss fifth-graders' competencies and self-concept in mathematics

COVID-19-related school closures in spring 2020 interrupted learning routines and posed a great challenge for students' competencies acquisition and self-concepts. Concerns about possible learning losses due to school closures, especially for disadvantaged students, are justified, but the currently available empirical evidence is still scarce, varies greatly with regard to context, and neglects reciprocal effects of competencies and self-concept. To address these shortcomings, this paper first provides insights on the effect that the 8 weeks of school closures had on Swiss primary school students' math competencies. IRT-based math tests were used to cross-sectionally compare data from 1,299 students in Grade 5 in late spring 2020 shortly after the reopening of schools with data from a previous year's cohort (n = 11,314) using propensity score matching. The results revealed no significant differences in math competencies and no evidence of an increase in inequality when children with not German (vs German) as their first language were studied. Second, changes in math self-concepts in the school year 2019/20, when the pandemic first hit, as well as reciprocal effects of math competencies and math self-concept were assessed longitudinally (n = 1,299) using random intercept cross-lagged panel models based on three measurement points. Results showed that higher math self-concept and positive change in math self-concept over the time of school closures were related to higher learning gains. Different development trajectories for children with German (vs not German) first language emerged. The study therefore fosters a better understanding of the effect that pandemic-induced school closures had on learning and relativizes the feared negative effects on math competencies caused by short school closures

Follow-up of the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults (SAPALDIA 2) 1991-2003: methods and characterization of participants

Summary.: Objectives: The Swiss Cohort Study on Air Pollution and Lung Diseases in Adults (SAPALDIA) was designed to investigate the health effects from long-term exposure to air pollution. Methods: The health assessment at recruitment (1991) and at the first reassessment (2001-3) consisted of an interview about respiratory health, occupational and other exposures, spirometry, a methacholine bronchial challenge test, end-expiratory carbon monoxide (CO) measurement and measurement for atopy. A bio bank for DNA and blood markers was established. Heart rate variability was measured using a 24-hour ECG (Holter) in a random sample of participants aged 50years and older. Concentrations of nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3) and particulates in ambient air have been monitored in all study areas since 1991. Residential histories collected over the 11year follow-up period coupled with GIS modelling will provide individual long-term air pollutant exposure estimates. Results: Of 9651 participants examined in 1991, 8715 could be traced for the cohort study and 283 died. Basic information about health status was obtained for 8047 individuals (86% of alive persons), 6528 individuals (70%) agreed to the health examination and 5973 subjects (62%) completed the entire protocol. Non-participants in the reassessment were on average younger than participants and more likely to have been smokers and to have reported respiratory symptoms in the first assessment. Average weight had increased by 5.5kg in 11years and 28% of smokers in 1991 had quit by the time of the reassessmen
