Implementing curriculum-embedded formative assessment in primary school science classrooms

The implementation of formative assessment strategies is challenging for teachers. We evaluated teachers’ implementation fidelity of a curriculum-embedded formative assessment programme for primary school science education, investigating both material-supported, direct application and subsequent transfer. Furthermore, the relationship between implementation fidelity and teacher variables was explored. N = 17 German primary school teachers participated in professional development on formative assessment, N = 11 teachers formed a control group. Teachers’ implementation fidelity was evaluated via classroom observations student ratings and an analysis of students’ workbooks, focusing on the frequency and quality of intended formative assessment elements (assessments, feedback and instructional adaptations). Regarding direct application, treatment group teachers’ implementation fidelity was high, with slight variations in quality. Regarding transfer, implementation fidelity was lower but teachers still implemented more formative assessment elements than the control group. Teachers’ pedagogical content knowledge and their evaluation of the formative assessment intervention were associated with implementation success.     

Brave new platforms: a possible platform future for highly decentralised schooling

ABSTRACT

Sweden has one of the most marketised and decentralised school systems in the world while also ranking amongst countries with the highest levels of access to technology in classrooms. Considering the increasingly central role that digital platforms play in the practices of schooling, this article speculates on what might happen during the 2020s in highly decentralised school systems like Sweden’s. Based on current trends in education, directions indicated by platformisation in other contexts and taking a critical speculative approach, it offers a discussion of what could happen to the practices of schooling and the public mission of education. This discussion is intended to raise important questions for researchers, educators and policy makers to consider as the platformisation of schooling unfolds.     

Evaluating a digital library self-archiving service: The BDBComp user case study

In this article, we present an overview of a self-archiving service for the Brazilian Digital Library of Computing (BDBComp) and describe a user experiment conducted to evaluate it. This experiment involved several potential real users, including computer science graduate students and professors, and archivists/librarians. The results of this study and their implications for similar services are described and analyzed, following sound statistical principles, which can serve as a basis for other similar studies. These results and their analysis indicate that we have successed in building a usable, efficient and learnable self-archiving service, properties which are essential to bring users to the system.     

The only constant is change: analysing and understanding change in sport and exercise psychology research

The ability to examine within-person change is essential to test process-based theories in sport and exercise psychology. Longitudinal data, whether experimental or observational, are prerequisites to be able to examine change processes, but most longitudinal studies in sport and exercise psychology focus solely on between-person/group differences, not on within-person change. In this review, we (1) provide researchers in the sport and exercise psychology field with a framework for longitudinal research that focuses on within-person change; (2) provide an overview of how researchers in sport and exercise psychology currently analyse longitudinal data, which showed that most longitudinal studies focus on between-person/group differences; and (3) provide examples of statistical models for analysing longitudinal data that correspond to the framework for longitudinal research. In the examples, we focus on latent variable modelling, such as latent growth-curve modelling and latent change-score modelling, which capture within-person change. We argue that there is a need for stronger emphasis on the match among theory of change, temporal design, and statistical models when designing longitudinal studies in sport and exercise psychology.     

Anthropogenic emission is the main contributor to the rise of atmospheric methane during 1993–2017

Atmospheric methane (CH₄) concentrations have shown a puzzling resumption in growth since 2007 following a period of stabilization from 2000 to 2006. Multiple hypotheses have been proposed to explain the temporal variations in CH₄ growth, and attribute the rise of atmospheric CH₄ either to increases in emissions from fossil fuel activities, agriculture and natural wetlands, or to a decrease in the atmospheric chemical sink. Here, we use a comprehensive ensemble of CH₄ source estimates and isotopic δ¹³C-CH₄ source signature data to show that the resumption of CH₄ growth is most likely due to increased anthropogenic emissions. Our emission scenarios that have the fewest biases with respect to isotopic composition suggest that the agriculture, landfill and waste sectors were responsible for 53 ± 13% of the renewed growth over the period 2007–2017 compared to 2000–2006; industrial fossil fuel sources explained an additional 34 ± 24%, and wetland sources contributed the least at 13 ± 9%. The hypothesis that a large increase in emissions from natural wetlands drove the decrease in atmospheric δ¹³C-CH₄ values cannot be reconciled with current process-based wetland CH₄ models. This finding suggests the need for increased wetland measurements to better understand the contemporary and future role of wetlands in the rise of atmospheric methane and climate feedback. Our findings highlight the predominant role of anthropogenic activities in driving the growth of atmospheric CH₄ concentrations.

The power of positioning: on the normalisation of gender,race/ethnicity,nation and class positions in a Swedish social work textbook

This article presents a feminist reading of a Swedish social work academic textbook as a case study. We use a discourse analytic approach and positioning theory, focusing on author positions through different story lines. The aim is to make visible how differences are created and positions of the author/reader normalised in terms of gender, race/ethnicity and class. The analysis illustrates how the organisation of the book privileges a particular story line by presenting gender research in a special section of the book and as a perspective. A neutral, unmarked author position is assumed, presented as a common ‘we’ by identifying ‘women researchers’ and ‘feminist’ points of departure as different. If the unmarked author/reader ‘we’ position appears desirable and morally superior, the clients’ gender, ethnicity and class are often openly discussed in relation to social problems, positioning them as ‘the other’. Finally there is also a story line of more critical and ambivalent knowledge positions.     

Different Methods – Different Results: How the Swedish Results in Mathematics Vary Depending on Methodological Approach

The results for TIMSS population 2 in Sweden indicated that Swedish student achievement in mathematics was average. There were even mass media reports that indicated that Swedish students had some of the lowest results in mathematics. The issue that is addressed in this article is whether the performance of Swedish students is average or even low. To answer this, the basis of comparison between the different countries needs to be discussed. Mass media, for example, based its comparison on all 45 countries participating in TIMSS population 2 and in its national TIMSS report, the Swedish National Agency for Education presented a different selection of countries. The report compared the results of the 25 countries that met the sampling requirements set by the TIMSS International Study Centre. This focuses the discussion on what approaches are used when comparing results from different countries in an international comparative study. In this article the TIMSS results, as presented by the Swedish National Agency for Education, are compared with the results obtained with other methodological approaches. The comparison is based on the importance of three variables for the results of the comparison: equal number of years in school, the selection of countries, and the contents of the textbooks in the different countries. The results indicate that the number of years in school, as well as the content of the textbooks in each country, are important factors when comparing the results for different countries.
