Abstraction is considered an essential aspect of computational thinking. Primary schools are starting to include computational thinking into the curriculum. However, in order to guide their support, teachers need to know how to recognize abstraction. In this paper, we present how we can observe abstraction …

The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

In the search for low greenhouse gas propulsion, the dual fuel engine provides a solution to use low carbon fuel at diesel-like high efficiency. Also a lower emission of NOx and particles can be achieved by replacing a substantial part of the diesel fuel by for example natural gas. Limitations can be …

De markt van groepsvakanties en groepsuitjes is sterk in beweging. Mensen gaan steeds meer in groepsverband op pad in wisselende samenstelling. Het aanbod kent steeds meer spelers naast de traditionele groepsaccommodaties. Ook op het gebied van marketing is de sector in beweging met een veelheid aan …

To maximize learning opportunities in physical education, a range of conditions need to be met. One of the most crucial conditions is qualified physical education teachers. This prompts us to suggest that it is crucial that physical education teacher candidates engage in meaningful, relevant, and worthwhile …

Binnen een periode van vier maanden heb ik bij Almende B.V. software gerealiseerd als onderdeel van het DIGICOR project. DIGICOR is een platform waarin partijen binnen supply chains kunnen samenwerken om zo de efficiëntie te verbeteren, kosten te besparen, risico’s te verminderen en innovatie te stimuleren. …

The use of molecular tools for the detection and identification of invertebrate species enables the development of more easily standardisable inventories of biological elements for water quality assessments, as it circumvents human-based bias and errors in species identifications. Current Ecological …

This abstract book contains summaries of all keynotes and individual contributions within the ‘International Overview’ and ‘PETE’ sessions, and 39 abstracts from the ‘mini-orals’ on original research, projects and initiatives on PE assessment. The AIESEP Specialist Seminar ‘Future Directions in PE …

VIDEO: Video recording of the AIESEP specialist seminar “Future Directions in PE Assessment” from October 18-20, 2018. Content of the seminar: Given the growing research interest in PE-assessment, the complexities PE-teachers meet in planning and carrying out assessment, and the increasing emphasis …
