This paper reports on an experiment comparing students’ results on image-rich numeracy problems and on equivalent word problems. Given the well reported problematic nature of word problems, the hypothesis is that students score better on image-rich numeracy problems than on comparable word problems. To test the hypothesis a randomized controlled trial was conducted with 31,842 students from primary, secondary, and vocational education. The trial consisted of 21 numeracy problems in two versions: word problems and image-rich problems. The hypothesis was confirmed for the problems used in this experiment. With the insights gained we intend to improve the assessment of students’ abilities in solving quantitative problems from daily life.

Talking and discussing with many partners during the way has brought us to the most original meaning of Teaching as ‘fostering learning’. The present Teaching case is the result of all those discussions and considerations united by the convincement that doing research is an essential part of that just mentioned fostering learning. Besides a Case to work on, the current Teaching Case includes a series of guidelines plus a body of thoughts and considerations to be taken into account when conducting research on places in all their complexity. In the endwe have all agreed on the importance of becoming more knowledgeable and better informed. It all implies a commitment to do so!The MAGE Case illustrated in this Teaching Case compilation has been mainly the product of an already existing interest in learning more about specific areas in our cities, often the areas in which new venues of our universities have been built. Working with partners in real life cases we experienced an increasingly sense of being part of the whole. We stopped calling the companies and institutions we were working with as potential ‘clients’ and started to build on a partnership’s cooperation narrative. Next steps in this trajectory have been to take the time to better establish the implications of seriously adopting this partnership narrative as a way of working together in research and education. In this sense, it has been indispensable to review terms such as co-creation, design thinking or teaching case and to come to grips by incorporating them as concepts in a case glossary.In terms of context, it is relevant to know that the current IMAGE Case as described in these pages has been elaborated in three different editions during the academic years 2020-2021 and 2021-2022. In each edition, we have been working with an international intercity cooperation from and within the cities of (in alphabetical order) Amsterdam, Barcelona, Lisbon, Paris and Vienna. The different schools and faculties are all part of higher education institutions in the cooperating cities and have a location in the focus areas of the case. Our districts and neighborhoods in the partner cities: Amsterdam -Zuidoost-; Barcelona -El Raval-; Lisbon -Carnide-; Paris -La Defènse-; Vienna -St. Marx-. During these two years we have been working together with students coursing different subjects and mostly in the bachelor courses. Lecturers and all kind of local partners have been closely involved in the process of making the case happen. The case description in this compilation shows intentionally the dates of the 3rd edition that took place in the second semester 2021-2022. This last edition helped to improve and re-see the Case after a period of lockdowns because of covid-19 pandemic regulations. Operating between the specific years of 2020-2022 has been an extraordinary experience in the literal sense of the word. The Covid-19 pandemic became an exceptional situation even for online intercity cooperation at a distance. Despite the longer experience built on online working together at a distance with international partners, the truly limitation of offline face-to face meetings at all levels, together with the experiences of being ill and even losing loved ones, has obviously had an impact. In terms of conducting research and collecting first-handdata, the restrictions have been clearly visible as well. Looking at the footage elaborated by the different students’ teams during the first and second edition one sees at once the emptiness of the streets, to name an example. The trigger for the current Case IMAGE Researching the City Mapping Imaginaries was mainly born from the increasing awareness that our look at cities' reputations (and at the reputations of areas within cities) could use a more diverse lens. Without denying the relevance of by now referential iconic places, there is a need to go beyond the already established and towards a new positioning for cities to capture a broader and more substantiated city map-- a map which contributes to seeing beyond the obvious towards the less generally known.This need is urgent. Even before Covid-19 pandemic and the cost of living crisis, many European cities were facing various challenges from mass tourism, to gentrification and decreasing livability in some urban areas. Despite city campaigns, which insist on spreading residents and visitors through all over our cities, cities tend themselves to concentrate attention, and investments, in areas that are already considered referential. But the crux is then, why not extend our view on how reputations and attention is built and really contribute to a more informed city mapping including a larger diversity of areas and centres of interest? Or as some creative entrepreneurs have put it: Instead of everybody aiming to be in a place that is already successful, wouldn't it be better to find new ways of making more places successful?

Many lithographically created optical components, such as photonic crystals, require the creation of periodically repeated structures [1]. The optical properties depend critically on the consistency of the shape and periodicity of the repeated structure. At the same time, the structure and its period may be similar to, or substantially below that of the optical diffraction limit, making inspection with optical microscopy difficult. Inspection tools must be able to scan an entire wafer (300 mm diameter), and identify wafers that fail to meet specifications rapidly. However, high resolution, and high throughput are often difficult to achieve simultaneously, and a compromise must be made. TeraNova is developing an optical inspection tool that can rapidly image features on wafers. Their product relies on (a) knowledge of what the features should be, and (b) a detailed and accurate model of light diffraction from the wafer surface. This combination allows deviations from features to be identified by modifying the model of the surface features until the calculated diffraction pattern matches the observed pattern. This form of microscopy—known as Fourier microscopy—has the potential to be very rapid and highly accurate. However, the solver, which calculates the wafer features from the diffraction pattern, must be very rapid and precise. To achieve this, a hardware solver will be implemented. The hardware solver must be combined with mechatronic tracking of the absolute wafer position, requiring the automatic identification of fiduciary markers. Finally, the problem of computer obsolescence in instrumentation (resulting in security weaknesses) will also be addressed by combining the digital hardware and software into a system-on-a-chip (SoC) to provide a powerful, yet secure operating environment for the microscope software.
National forestry Commission (SBB) and National Park De Biesbosch. Subcontractor through NRITNational parks with large flows of visitors have to manage these flows carefully. Methods of data collection and analysis can be of help to support decision making. The case of the Biesbosch National Park is used to find innovative ways to figure flows of yachts, being the most important component of water traffic, and to create a model that allows the estimation of changes in yachting patterns resulting from policy measures. Recent policies oriented at building additional waterways, nature development areas and recreational concentrations in the park to manage the demands of recreation and nature conservation offer a good opportunity to apply this model. With a geographical information system (GIS), data obtained from aerial photographs and satellite images can be analyzed. The method of space syntax is used to determine and visualize characteristics of the network of leisure routes in the park and to evaluate impacts resulting from expected changes in the network that accompany the restructuring of waterways.
This PD project aims to gather new knowledge through artistic and participatory design research within neighbourhoods for possible ways of addressing and understanding the avoidance and numbness caused by feelings of vulnerability, discomfort and pain associated with eco-anxiety and chronic fear of environmental doom. The project will include artistic production and suitable forms of fieldwork. The objectives of the PD are to find answers to the practice problem of society which call for art that sensitises, makes aware and helps initiate behavioural change around the consequences of climate change. Rather than visualize future sea levels directly, it will seek to engage with climate change in a metaphorical and poetic way. Neither a doom nor an overly techno-optimistic scenario seem useful to understand the complexity of flood risk management or the dangers of flooding. By challenging both perspectives with artistic means, this research hopes to counter eco-anxiety and create a sense of open thought and susceptibility to new ideas, feelings and chains of thought. Animation and humour, are possible ingredients. The objective is to find and create multiple Dutch water stories, not just one. To achieve this, it is necessary to develop new methods for selecting and repurposing existing impactful stories and strong images. Citizens and students will be included to do so via fieldwork. In addition, archival materials will be used. Archives serve as a repository for memory recollection and reuse, selecting material from the audiovisual archive of the Institute of Sound & Vision will be a crucial part of the creative work which will include two films and accompanying music.
