- From a circular economyperspective, one-pot strategies for theisolation of cellulose nanomaterials at a high yield and with multifunctionalproperties are attractive. Here, the effects of lignin content (bleachedvs unbleached softwood kraft pulp) and sulfuric acid concentrationon the properties of crystalline lignocellulose isolates and theirfilms are explored. Hydrolysis at 58 wt % sulfuric acid resulted inboth cellulose nanocrystals (CNCs) and microcrystalline celluloseat a relatively high yield (>55%), whereas hydrolysis at 64 wt% gaveCNCs at a lower yield (<20%). CNCs from 58 wt % hydrolysis weremore polydisperse and had a higher average aspect ratio (1.5-2x),a lower surface charge (2x), and a higher shear viscosity (100-1000x).Hydrolysis of unbleached pulp additionally yielded spherical nanoparticles(NPs) that were <50 nm in diameter and identified as lignin bynanoscale Fourier transform infrared spectroscopy and IR imaging.Chiral nematic self-organization was observed in films from CNCs isolatedat 64 wt % but not from the more heterogeneous CNC qualities producedat 58 wt %. All films degraded to some extent under simulated sunlighttrials, but these effects were less pronounced in lignin-NP-containingfilms, suggesting a protective feature, but the hemicellulose contentand CNC crystallinity may be implicated as well. Finally, heterogeneousCNC compositions obtained at a high yield and with improved resourceefficiency are suggested for specific nanocellulose uses, for instance,as thickeners or reinforcing fillers, representing a step toward thedevelopment of application-tailored CNC grades.

- Severe accidents and high costs associated with weather-related events already occur in today’s climate. Unless preventive measures are taken, the costs are expected to increase in future due to ongoing climate change. However, the risk reduction measures are costly as well and may result in unwanted impacts. Therefore, it is important to identify, assess and prioritize which measures are necessary to undertake, as well as where and when these are to be undertaken. To be able to make such evaluations, robust (scientifically based), transparent and systematic assessments and valuations are required. This article describes a framework to assess the cause-and-effect relationships and how to estimate the costs and benefits as a basis to assess and prioritize measures for climate adaptation of roads and railways. The framework includes hazard identification, risk analysis and risk assessment, identification, monetary and non-monetary evaluation of possible risk reduction measures and a step regarding distribution-, goal-and sensitivity analyses. The results from applying the framework shall be used to prioritize among potential risk reduction measures as well as when to undertake them.

Activating students as resources in physical education – a complex process making symbolic, social and physical capital visible
- 2022

Konferensbidrag (refereegranskat)abstract
- It is well established that Assessment for Learning (AfL) is a model for assessment that strengthens young peoples’ learning in schools as well as in higher education. This is also the case in school physical education and in physical education teacher education (PETE). One of the key learning strategies in AfL is to activate peers as resources for learning, often operationalized as peer assessment. In physical education, peer assessment has proven to strengthen learning for both the observer and the observed.One dimension of peer assessment, that has only scarcely been covered in the physical education context, but that is more highlighted in research of peer assessment in general teacher education, is the tensions inherent in giving feedback to peers, and perhaps friends, on their work. It has been argued that teacher students do not feel comfortable when critiquing other teacher students, and that peer assessment could reflect friendships more than learning outcomes.In the physical education context, studies have shown that peer assessment is one area that physical education teachers are sceptical about. Further, it has been argued that pupils can be mean to each other if implementing peer assessment during physical education teaching. In this paper we aim to dig deeper into this problematic aspect of peer assessment in physical education.More specifically, drawing on the French sociologist Pierre Bourdieu’s concept of capital and using qualitative methodology, the question that will guide our analysis reads:What capabilities and behaviours among students are by PETE students and physical education teachers acknowledged as legitimate and valuable when peer assessment is implemented in physical education teaching? Preliminary results show that in order for peer assessment to be successful in physical education teaching questions regarding who gives feedback on what needs to be considered.

Activating students as resources in physical education teacher education – a complex process making social and physical capital visible.

Konferensbidrag (refereegranskat)abstract
- It is well established that students in higher education need to develop evaluative skills in order to become effective learners (Guest & Riegler 2022). Assessment for Learning (AfL) is a model for assessment that strengthens learning in schools as well as in higher education (Black et al 2002). This is also the case in physical education teacher education (PETE) (Eather et al 2017, Macken et al 2020) and in school physical education (Leirhaug 2016). One of the key learning strategies in AfL is to activate peers as resources for learning, often operationalised as peer assessment. In PETE, peer assessment (or peer-assisted learning in a broader meaning) has proven to strengthen learning for both the observer and the observed (Lamb et al 2012). One dimension of peer assessment, that has only scarcely been covered in the PETE context (Macken et al 2020) but that is more highlighted in research of peer assessment in general teacher education (see e.g. Kilic 2016, Tait-McCutcheon & Bernadette Knewstubb 2018), is the tensions inherent in giving feedback to peers on their work, peers who might also often be friends. According to Kilic (2016, 137) preservice teachers “do not feel comfortable when critiquing another student” and Tait-McCutcheon and Knewstubb (2018, 773) argues that “peer assessment could reflect friendships more than learning outcomes”. Research demonstrates a complexity with regards to the potential for peer assessment in PETE. On the one hand, preservice teachers have expressed that giving feedback to peers creates a positive, safe, equal and relaxed learning environment (Lamb et al., 2012) and peer assessment has been reported to improve competence, confidence and self-efficacy among preservice teachers (Eather et al., 2017). On the other hand, a study by Macken et al. (2020) reported that preservice teachers believe their students would be mean to each other if implementing peer assessment during their school placement practice in PETE.In this paper, we aim to further explore the complexity involved in peer assessment in PETE to get a deepened and more differentiated picture of this phenomenon. Our overall aim is to contribute to more knowledge about how to involve preservice teachers in PETE and students in school physical education as resources for learning without risking to cause harm. Drawing on the call from Scanlon et al. (2022) for more studies on how assessment is taught in PETE, our specific aim in this paper is to investigate preservice teachers’ views on what as well as how peer assessment is taught in PETE, to be used in school physical education. We will use Pierre Bourdieu’s (1990) concept of capital, as well as the work of Hay and Penney (2013) on how accountability mechanisms functions in assessment, in order to analyse what is assigned value in peer assessment. The two questions that will guide our analysis in this paper reads: What mechanisms are assigned value in peer assessment according to preservice teachers in PETE? And: How do the mechanisms that are assigned value in peer assessment in PETE function according to preservice teachers? More knowledge about the what and the how in teaching of assessment practices in PETE can improve these practices within school physical education.MethodologyThe study presented in this paper is conducted as part of a greater project with the aim of exploring how PETE matters for school physical education. In the overall project we have recruited preservice teachers, with physical education as one of their subjects, during their last year in teacher education. During this last year, one campus-placed course in assessment and one school placement course, constituted the contexts from which we collected empirical material to this study (Authors 2021). The participants in this study were 21 preservice teachers from two different PETE institutions in Sweden (10 from uni A and 11 from uni B). The empirical material analysed in this study compriced of: Three audio-recorded seminars (90-120 min each) from the campus-based assessment courses (one seminar from uni A and two from uni B) conducted before the preservice teachers’ school placement studies.Seven individual semi-structured interviews (40-70 min each) (Kvale 1996) conducted during visits at the preservice teachers’ school placement studies (all from uni A).Five individual Stimulated Recall (SR)-interviews conducted during visits at the preservice teachers’ school placement studies (one from A, four from B).Two audio-recorded and semi-structured group interviews (40-60 min each) (Kvale 1996) from the campus-based assessment courses (both from A) conducted after the school placement studies. After having had the empirical material transcribed by an external part, a thematic content analysis was initiated by a process of familiarisation in which all four researchers were engaged (Braun et al 2017). Inspired by an abductive approach (Alvesson & Sköldberg 2017), we allowed ourselves to be open to alternative theories that could help explain the empirical material. The choice of research object was initiated by the impression from the interviews that giving feedback to peers is surrounded by a complexity, both in PETE and in school physical education. The identification of social relationships and certain types of bodies and movements as assigned with value when giving feedback to peers guided our attention towards Bourdieu-inspired interpretations of the social capital (Beames & Atencio 2008) and the physical capital (Redelius & Hay 2010). Educational challenges following when ‘the what’ is reflected in ‘the how’The findings indicate that when the what-aspect of ‘social relationships’ is to be implemented into an how-aspect, the preservice teachers calls for continuous interaction ‘over time’ in order to build a safe and an allowing climate for learning. While this interaction can be implemented in PETE and in school physical education, allowing for school children to build social capital (Beames & Atencio 2008), a result from this study that calls for further discussion is how PETE can make continuous interaction between preservice teachers and school students possible during school placement studies. When the what-aspect of ‘articulating what to learn’ is mirrored in relation to the how-aspect of giving ‘correct feedback’ in peer assessment, this displays that physical capital in school physical education is strongly connected to standards of excellence and norms of right and wrong movement technique (Redelius & Hay 2010). These golden norms seem to be upheld by the displayed lack a common language for learning (Larsson & Redelius 2008). A question following from this study is what resources preservice teachers are offered within PETE to embody a language for learning in school physical education? This study also made visible that ‘the emphasis of certain forms of knowledge ’ is highly valued when preservice teachers are to give feedback to their peers, to their students (during school placement) or when they engage students to give feedback to each other. The preservice teachers claim to handle this ‘what-aspect’ of peer assessment by focus their attention on ‘managing the sensitivity’ arising when themselves or their students are to comment on each others’ bodies in movements. In conclusion, the combination of social and physical capital decides what is possible to say to whom when preservice teachers and students are to give feedback to peers in PETE and in school physical education.ReferencesAlvesson M and Sköldberg K (2017) Tolkning och Reflektion.

Konferensbidrag (refereegranskat)abstract
- Formative assessment strategies are often conceived as central within teacher edu-cation (Cañadas 2023). These strategies are to be learned as content during teacher education and then transformed into methods when newly graduated teachers (NQT) enter their occupational practice. The aim of this presentation is to contribute to knowledge of how content discourses in physical education teacher education (PETE) matter for physical education (PE) practice. We will do this by answering two research questions: 1. What components of formative assessment are made visible in PE by NQTs? 2. What components of the formative assessment discourse can be traced back to PETE? This study is part of a larger project investigating transitions of content discourses from PETE to school PE. Data was collected from participants when they were engaged in two different educational contexts: in PETE as preserv-ice teachers (PST) and in PE as NQTs. In the PETE context, a total of 26 PSTs stud-ying at two different Swedish PETE institutions (15 from A and 11 from B) partici-pated. In the PE context, a total of 13 PE teachers (from the group of 26 PSTs), having graduated from the two Swedish PETE institutions (9 from A and 4 from B), participated. Data collection methods from the two contexts were video-recorded and visual observations, group interviews, individual interviews, Stimulated Recall (SR)-interviews and text analysis of course handbooks. In the study we use the con-cept pedagogic discourse (Bernstein 1990) to describe how content is constructed, recontextualised and realised through text, talk and practice. The way in which the NQTs in this study talk about formative assessment thus illustrate what constitutes this discourse in school PE. In the preliminary analysis, four components (sharing learning objectives, feedback, using students as resources, and grading) have been discerned as dominating. Inspired by Foucault’s (1991) genealogical approach, we will also search for traces of dominating and marginalized components of the form-ative assessment discourse in the PETE context, and the PSTs talk about formative assessment. We will draw on research on didactics in PE (Quennerstedt & Larsson, 2015) to analyse what components the formative assessment discourse in PE and PETE is built of, how and why formative assessment is conducted in a certain way, and who the producers of the components building the formative assessment dis-course in PE and PETE are.ReferencesBernstein, B.

- Background: In this paper, we will address the question of how physical education teacher education (PETE) matters and suggest one way to explore the potential impact of PETE. A distinguishing feature of the studies of PETE's impact on physical education is that they either include perspectives from preservice teachers involved in PETE courses or perspectives from physical education teachers in schools looking back at their education. Longitudinal attempts to follow preservice teachers’ journey from education to workplace, in order to grasp how they perceive the relation between teacher education and teaching practice in schools, and the transition between these contexts, are few and far between. This gap of knowledge is a missing piece of the puzzle to further develop PETE, and to inform life-long professional development for teachers.Purpose: The purpose of this paper is twofold. First, we develop and present a methodological approach for investigating the transition of content areas from courses in PETE into teaching practice in school physical education. Second, we will illustrate the potential utility of this methodological approach in longitudinal studies by showing how one particular content area, Assessment for Learning (AfL), was investigated through the use of methods and theories described in the first part of this paper.Methodology: The suggested longitudinal approach involves Stimulated Recall (SR) interviews with pre- and postservice teachers, observations and communication with groups of students and teachers through social media. The construction, recontextualisation and realisation of pedagogic discourses regarding content areas are suggested to be analysed through a combination of Bernstein's concept of the pedagogic device and Ball's concept of fabrication.Results and Conclusions: The longitudinal design and the suggested methodology can provide answers to how content areas are transformed in and between PETE and school physical education. A combination of the theoretical perspectives of Bernstein and Ball enables us to say something not only about how pedagogic discourses regarding content areas are constructed, recontextualised and realised in PETE and school physical education, but also about what content areas become in terms of fabrications in the transition between these contexts. To conclude, we argue that the methodological research design can be used to explore different content areas in PETE and that this methodology can contribute to knowledge about how PETE matters for school physical education.

A distinguishing feature of the studies of PETE’s impact on physical education is that they either include perspectives from preservice teachers involved in PETE courses or perspectives from physical education teachers in schools looking back at their education. Longitudinal attempts to follow preservice teachers’ journey from education to workplace, in order to grasp how they perceive the relation between teacher education and teaching practice in schools, and transitionsbetween these contexts, are few and far between. This gap of knowledge is a missing piece of the puzzle to further develop PETE, and to inform courses or life-long professional development for teachers. The purpose of this paper is to present a methodological approach for investigating transitions of content areas from courses in PETE into teaching practice in school physical education. This will be done trough combining the theoretical perspectives of Bernstein and Ball with a longitudinal study design. The theory of Bernstein enables us to say something about howpedagogic discourses are constructed, recontextualised and realised in PETE and in school physical education. The theory of Ball enables us to say something about about whatcontent areas become, in terms of fabrications, in the transition between these contexts. The longitudinal design will provide us with answers to how and what pedagogic discourses regarding content areas are transformed into in and between PETE and school physical education. The suggested methodology involves Stimulated Recall (SR) interviews, observations and communication with groups through social media. SR-interviews provides an immediateness in the reflection on teaching practice and content areas. Using social media groups is an effective strategy for maintaining contact with examined preservice teachers when they leave university.
