This study aimed to describe verbal student–teacher interactions in vocational education from a socio-cultural perspective on negotiation of meaning. Teaching as part of these interactions is addressed by a combination of diagnosing, checking and intervening strategies. A study was conducted in which students (n students = 20) and teacher (n teachers = 5) from Social Work (SW) and Information and Communication Technology (ICT) worked together in small groups (n groups = 5) discussing vocational core problems. Each group held five discussions (n discussions = 25). All discussions were audio recorded and transcribed before they were analysed for negotiation of meaning including teaching strategies. The results showed that 5–8% of the interactions include negotiation of meaning. Interactions in SW groups revealed more negotiation of meaning than in interactions in ICT groups. Teaching strategies mainly included checking and intervening activities in favour of diagnosing activities. Furthermore, teachers used meta-cognitive and conceptual interventions most frequently. The implications of these results are discussed by reflecting on occupational differences and on how negotiation of meaning including teaching strategies can be enhanced.
Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate and compare arithmetic means of histograms and case-value plots? We designed four item types: two requiring mean estimation and two requiring means comparison. Analysis of gaze data of 50 students (15–19 years old) solving these items was triangulated with data from cued recall. We found five strategies. Two hypothesized most common strategies for estimating means were confirmed: a strategy associated with horizontal gazes and a strategy associated with vertical gazes. A third, new, count-and-compute strategy was found. Two more strategies emerged for comparing means that take specific features of the distribution into account. In about half of the histogram tasks, students used correct strategies. Surprisingly, when comparing two case-value plots, some students used distribution features that are only relevant for histograms, such as symmetry. As several incorrect strategies related to how and where the data and the distribution of these data are depicted in histograms, future interventions should aim at supporting students in understanding these concepts in histograms. A methodological advantage of eye-tracking data collection is that it reveals more details about students’ problem-solving processes than thinking-aloud protocols. We speculate that spatial gaze data can be re-used to substantiate ideas about the sensorimotor origin of learning mathematics.

Due to societal developments, like the introduction of the ‘civil society’, policy stimulating longer living at home and the separation of housing and care, the housing situation of older citizens is a relevant and pressing issue for housing-, governance- and care organizations. The current situation of living with care already benefits from technological advancement. The wide application of technology especially in care homes brings the emergence of a new source of information that becomes invaluable in order to understand how the smart urban environment affects the health of older people. The goal of this proposal is to develop an approach for designing smart neighborhoods, in order to assist and engage older adults living there. This approach will be applied to a neighborhood in Aalst-Waalre which will be developed into a living lab. The research will involve: (1) Insight into social-spatial factors underlying a smart neighborhood; (2) Identifying governance and organizational context; (3) Identifying needs and preferences of the (future) inhabitant; (4) Matching needs & preferences to potential socio-techno-spatial solutions. A mixed methods approach fusing quantitative and qualitative methods towards understanding the impacts of smart environment will be investigated. After 12 months, employing several concepts of urban computing, such as pattern recognition and predictive modelling , using the focus groups from the different organizations as well as primary end-users, and exploring how physiological data can be embedded in data-driven strategies for the enhancement of active ageing in this neighborhood will result in design solutions and strategies for a more care-friendly neighborhood.
Chronische pijn is een groot, complex en duur probleem en heeft een grote impact op de kwaliteit van leven van patiënten, dagelijks functioneren, stemming en ziekteverzuim. Er zijn verschillende interventies ontwikkeld die met name gericht zijn op het beïnvloeden en veranderen van het gedrag waarbij zelfmanagement een belangrijke rol speelt. Echter het bestendigen van resultaten op lange termijn blijkt een groot probleem en leidt zelfs tot terugval naar “oud” gedrag waardoor patiënten opnieuw vaak kostbare hulp gaan zoeken. Er zijn twee additionele interventies ontwikkeld in een eerder RAAK-project (SOLACE) ter voorkoming van deze terugval: “Do It Your Self” en “Waarde gerichte Doelen” , echter de werkzaamheid van deze interventies op de lange termijn is niet onderzocht. Een eerste feasibility studie lijkt veelbelovend met positieve effecten naar de bruikbaarheid van deze interventies in de betrokken revalidatiecentra. Vanuit dit werkveld maar ook vanuit de patiënten kwam nadrukkelijk de vraag om deze interventies op effectiviteit te toetsen. Dit heeft geleid tot de onderzoeksvraag; “Is een additionele interventie (do it yourself en/of waarde gerichte doelen) gericht op het blijven toepassen van aangeleerde vaardigheden na een succesvol doorlopen pijn programma effectief in het bestendigen van de resultaten op de lange termijn en leidt dit tot een afname van het zorggebruik.” Het onderzoek wordt uitgevoerd in twee werkpakketten; (1) het ontwikkelen van een bruikbare app voor de ontwikkelde interventies in samenwerking met DIO Design en (2) een effectiviteit studie in de revalidatiecentra Adelante in Hoensbroek en Maastricht, Libra R&A locatie Weert en Heliomare Revalidatie in Wijk aan Zee. De doelstelling van het consortium is om de samen met zorgprofessionals, patiënten, beroepsvereniging en ontwerpers een product ter voorkoming van terugval verder te ontwikkelen en te toetsen. Na afronding van dit project zijn de op effectiviteit getoetste additionele interventies, DIY en WD, klaar om landelijk te worden uitgerold.
Worldwide, coral reefs are rapidly declining due to increased sea water temperatures and other environmental stresses (Figure 1). To counter the extinction of major coral reef building species on the island of Bonaire, the non-profit organization Reef Renewal Foundation Bonaire is restoring degraded reef sites using corals that are grown in local nurseries. In these nurseries, corals are propagated on artificial trees using fragmentation. After 6-8 months of growth in the nursery, the corals are transplanted to degraded reef sites around the island. Over the years more than 21.000 corals have been outplanted to reef restoration sites in this way. These corals show high survivorship under natural reef conditions but remain under threat by environmental disturbances, such as increased water temperatures, diseases, and competition with macroalgae. A promising intervention to increase reef persistence and resilience is to manipulate the coral-associated microbiome. At present, the composition of the microbiome in nursery-reared and outplanted corals on Bonaire is unknown. The aim of the current project is to identify and isolate naturally occurring beneficial bacteria that may stimulate the resilience of these corals. Our key objectives are: 1) to assess the presence of functionally beneficial bacteria in corals in nursery and restoration sites on Bonaire using metagenomic screening. 2) to design culture strategies to isolate these functionally beneficial bacteria. In the future, a selection of these beneficial bacteria can be applied to the corals to increase their resilience against environmental disturbances.
