Given the complexity of teaching, continuing teacher professional development (CPD) is essential for maintaining and enhancing teaching effectiveness, and bridging the gap between ever-evolving theory and practice. Technological advancements have opened new opportunities for digital tools to support CPD. However, the successful integration of such digital tools into practice poses challenges. It requires adherence to CPD prerequisites and acknowledgment of the complexity of the professional development process. This study explored the applicability of the developed digital PE teacher professional development TARGET-tool in a secondary school PE context. We examined the perceived usability of this tool and gained insights into the process of teachers’ professional development as a result of using the tool. Ten PE teachers from different schools implemented the TARGET- tool within their PE context for a period of 4 to 6 weeks. Individual semi-structured inter- views and the System Usability Scale provided insights into the perceived usability and the process of teacher professional development. The TARGET-tool demonstrated its potential as an effective tool for supporting teachers’ professional development. Future tool improve- ments were identified to further optimize the perceived usability, such as simplifying com- plex features, providing additional support and resources, and improving (data) presenta- tions. Using the Interconnected Model of Professional Growth as a theoretical basis, it was demonstrated how the use of the TARGET-tool engages teachers as active and reflective participants in their professional development and induces changes within the external domain, the domain of practice, the domain of consequences, and the personal domain.
Enjoyment in primary physical education (PE) is a key factor in increasing children's physical activity engagement in PE and leisure time. While existing PE research has largely focused on a motivational PE climate and meaningful experiences in PE, research on children's perceptions of enjoyable teaching practices (TPs) in PE is limited. Therefore, this study aimed to explore primary school children's perspectives on TPs that foster PE enjoyment. In addition, we observed to what extent these TPs were applied in daily PE practice. Four focus groups with 10- to 12-year-old children (12 boys, 12 girls) from four primary schools were formed and inductive analysis resulted in 32 child-identified TPs categorized into 10 dimensions. Thirty-one PE lessons taught by 19 different PE teachers (11 generalists, 8 PE specialists) were recorded and coded using the child-identified TPs. Teachers regularly performed a substantial number of these TPs during their PE lessons. However, TPs such as the use of cooperative learning, instructional methods to promote children's (social) learning process, an emphasis on children's individual improvements, and consciously grouping were rarely observed. Moreover, PE specialists showed TPs supporting exploratory learning and children's individual learning processes more frequently than generalists. In addition, PE specialists provided challenging, differentiated tasks with a creative use of equipment more often than generalists. Including children's perspectives contributes to a comprehensive understanding of PE enjoyment and TPs that can promote enjoyable PE experiences. Children's voices need to be heard continuously by PE teachers to ensure enjoyable PE experiences for all children.
It has been suggested that physical education (PE) and active transport can make a meaningful contribution to children's physical activity (PA) levels. However, data on the contribution these activities to total PA is scarce, and PE's contribution to total physical activity energy expenditure (PAEE) has to our knowledge never been determined. This is probably explained by the methodological complexity of determining PAEE (Welk, 2002). In this paper, we present the first data of an ongoing study using combined heart rate monitoring and accelerometry, together with activity diaries. Over the six measurement days, PE contributed 5% to total PAEE, and 16% to school-related PAEE, whereas active transportation had a much larger contribution.
Designing cities that are socially sustainable has been a significant challenge until today. Lately, European Commission’s research agenda of Industy 5.0 has prioritised a sustainable, human-centric and resilient development over merely pursuing efficiency and productivity in societal transitions. The focus has been on searching for sustainable solutions to societal challenges, engaging part of the design industry. In architecture and urban design, whose common goal is to create a condition for human life, much effort was put into elevating the engineering process of physical space, making it more efficient. However, the natural process of social evolution has not been given priority in urban and architectural research on sustainable design. STEPS stems from the common interest of the project partners in accessible, diverse, and progressive public spaces, which is vital to socially sustainable urban development. The primary challenge lies in how to synthesise the standardised sustainable design techniques with unique social values of public space, propelling a transition from technical sustainability to social sustainability. Although a large number of social-oriented studies in urban design have been published in the academic domain, principles and guidelines that can be applied to practice are large missing. How can we generate operative principles guiding public space analysis and design to explore and achieve the social condition of sustainability, developing transferable ways of utilising research knowledge in design? STEPS will develop a design catalogue with operative principles guiding public space analysis and design. This will help designers apply cross-domain knowledge of social sustainability in practice.
Aanleiding: De belangstelling voor gezonde en veilige voeding is groot. Bij de gezondheidseffecten van voeding spelen de darmen een cruciale rol. Verschillende soorten bedrijven hebben behoefte aan natuurgetrouwe testmodellen om de effecten van voeding op de darmen te bestuderen. Ze zijn vooral op zoek naar modellen waarvan de uitkomsten direct vertaalbaar zijn naar het doelorganisme (de mens of bijvoorbeeld het varken) en die niet gebruikmaken van kostbare en maatschappelijke beladen dierproeven. Doelstelling Het project 2-REAL-GUTS heeft als doel om twee innovatieve dierproefvrije darmmodellen geschikt te maken voor onderzoek naar voedingsconcepten en -ingrediënten. De twee darmmodellen die worden toegepast zijn darmorganoïden, minidarmorgaantjes bestaande uit stamcellen, en darmexplants bestaande uit hele stukjes darm verkregen uit relevante organismen. Beide modellen hebben potentieel heel uitgebreide toepassingsmogelijkheden en hebben ook grote voordelen ten opzichte van de huidige veelgebruikte cellijnen, omdat ze meerdere in de darm aanwezige celtypen bevatten en uit verschillende specifieke darmregio's te verkrijgen zijn. Gezamenlijk gaan de partners werken aan: 1) het aanpassen van de kweekomstandigheden zodat darmmodellen geschikt worden om de vragen van partners te beantwoorden; 2) het vaststellen van de toepassingsmogelijkheden van de darmmodellen door verschillende stoffen en producten te testen. Beoogde resultaten Kennisconferenties, publicaties en exploitatie van de modellen zullen zorgen voor het verspreiden van de opgedane kennis. Omdat het project gebruikmaakt van moderne, op de toekomst gerichte laboratoriumtechnieken (kweekmethoden met stamcellen en vitaal weefsel, moleculaire analyses en microscopie), leent het zich uitstekend om geïmplementeerd te worden in het hbo-onderwijs. Als spin-off zal het project dan ook voorzien in een specifieke, voor Nederland unieke hbo-minor op het gebied van stamcel- en aanverwante technologie (zoals organ-on-a-chiptechnologie).
In this proposal, a consortium of knowledge institutes (wo, hbo) and industry aims to carry out the chemical re/upcycling of polyamides and polyurethanes by means of an ammonolysis, a depolymerisation reaction using ammonia (NH3). The products obtained are then purified from impurities and by-products, and in the case of polyurethanes, the amines obtained are reused for resynthesis of the polymer. In the depolymerisation of polyamides, the purified amides are converted to the corresponding amines by (in situ) hydrogenation or a Hofmann rearrangement, thereby forming new sources of amine. Alternatively, the amides are hydrolysed toward the corresponding carboxylic acids and reused in the repolymerisation towards polyamides. The above cycles are particularly suitable for end-of-life plastic streams from sorting installations that are not suitable for mechanical/chemical recycling. Any loss of material is compensated for by synthesis of amines from (mixtures of) end-of-life plastics and biomass (organic waste streams) and from end-of-life polyesters (ammonolysis). The ammonia required for depolymerisation can be synthesised from green hydrogen (Haber-Bosch process).By closing carbon cycles (high carbon efficiency) and supplementing the amines needed for the chain from biomass and end-of-life plastics, a significant CO2 saving is achieved as well as reduction in material input and waste. The research will focus on a number of specific industrially relevant cases/chains and will result in economically, ecologically (including safety) and socially acceptable routes for recycling polyamides and polyurethanes. Commercialisation of the results obtained are foreseen by the companies involved (a.o. Teijin and Covestro). Furthermore, as our project will result in a wide variety of new and drop-in (di)amines from sustainable sources, it will increase the attractiveness to use these sustainable monomers for currently prepared and new polyamides and polyurethanes. Also other market applications (pharma, fine chemicals, coatings, electronics, etc.) are foreseen for the sustainable amines synthesized within our proposition.
