Background: The worldwide increase in the rates of childhood overweight and physical inactivity requires successful prevention and intervention programs for children. The aim of the Active Living project is to increase physical activity and decrease sedentary behavior of Dutch primary school children by developing and implementing tailored, multicomponent interventions at and around schools. Methods/design: In this project, school-centered interventions have been developed at 10 schools in the south of the Netherlands, using a combined top-down and bottom-up approach in which a research unit and a practice unit continuously interact. The interventions consist of a combination of physical and social interventions tailored to local needs of intervention schools. The process and short- and long-term effectiveness of the interventions will be evaluated using a quasi-experimental study design in which 10 intervention schools are matched with 10 control schools. Baseline and follow-up measurements (after 12 and 24 months) have been conducted in grades 6 and 7 and included accelerometry, GPS, and questionnaires. Primary outcome of the Active Living study is the change in physical activity levels, i.e. sedentary behavior (SB), light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and counts-per-minute (CPM). Multilevel regression analyses will be used to assess the effectiveness of isolated and combined physical and social interventions on children’s PA levels. Discussion: The current intervention study is unique in its combined approach of physical and social environmental PA interventions both at school(yard)s as well as in the local neighborhood around the schools. The strength of the study lies in the quasi-experimental design including objective measurement techniques, i.e. accelerometry and GPS, combined with more subjective techniques, i.e. questionnaires, implementation logbooks, and neighborhood observations.

The aim of the current study was to examine the effectiveness of a school-centered multicomponent PA intervention, called ‘Active Living’, on children's daily PA levels. A quasi-experimental design was used including 9 intervention schools and 9 matched control schools located in the Netherlands. The baseline measurement took place between March–June 2013, and follow-up measurements were conducted 12 months afterwards. Accelerometer (ActiGraph, GT3X +) data of 520 children aged 8–11 years were collected and supplemented with demographics and weather conditions data. Implementation magnitude of the interventions was measured by keeping logbooks on the number of implemented physical environmental interventions (PEIs) and social environmental interventions (SEIs). Multilevel multivariate linear regression analyses were used to study changes in sedentary behavior (SB), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) between baseline and follow-up. Finally, effect sizes (ESs) were calculated using Cohen's d. No pooled effects on PA and SB were found between children exposed and not exposed to Active Living after 12 months. However, children attending Active Living schools that implemented larger numbers of both PEIs and SEIs engaged in 15 more minutes of LPA per weekday at follow-up than children in the control condition (ES = 0.41; p < .05). Moreover, children attending these schools spent less time in SB at follow-up (ES = 0.33), although this effect was non-significant. No significant effects were found on MVPA. A school-centered multicomponent PA intervention holds the potential to activate children, but a comprehensive set of intervention elements with a sufficient magnitude is necessary to achieve at least moderate effect sizes.

Maintaining the child-robot relationship after a significant break, such as a holiday, is an important step for developing sustainable social robots for education. We ran a four-session user study (n = 113 children) that included a nine-month break between the third and fourth session. During the study, participants practiced math with the help of a social robot math tutor. We found that social personalization is an effective strategy to better sustain the child-robot relationship than the absence of social personalization. To become reacquainted after the long break, the robot summarizes a few pieces of information it had stored about the child. This gives children a feeling of being remembered, which is a key contributor to the effectiveness of social personalization. Enabling the robot to refer to information previously shared by the child is another key contributor to social personalization. Conditional for its effectiveness, however, is that children notice these memory references. Finally, although we found that children's interest in the tutoring content is related to relationship formation, personalizing the topics did not lead to more interest in the content. It seems likely that not all of the memory information that was used to personalize the content was up-to-date or socially relevant.

Bij de ontwikkeling van kinderen speelt de omgeving waarin zij opgroeien en de wijze waarop zij zich verbonden voelen met hun buurt een belangrijke rol (Owens, 2004; 2016). Om als basisschool goed bij te kunnen dragen aan de ontwikkeling van kinderen is het van belang dat scholen de omgeving en de buurt waarin hun leerlingen opgroeien kennen en kunnen benutten voor hun onderwijs. In het bijzonder gaat het daarbij om de betekenis die deze omgeving voor hun leerlingen heeft. Voor basisscholen in wijken met een grote diversiteit aan inwoners kan de betekenis van eenzelfde omgeving voor verschillende leerlingen ook zeer verschillend zijn. Naar de wijze waarop kinderen zich verbonden voelen met de fysieke en sociale ruimte is nog weinig onderzoek gedaan (Tani, 2016). Naast inzicht in de bestaande verbinding van kinderen met hun omgeving is het voor het onderwijs belangrijk om inzicht te verkrijgen in de wijze waarop kinderen in staat kunnen worden gesteld om zich te binden aan een plek en om deze plek te benutten bij hun ontwikkeling. De capability approach (Nussbaum, 2014) en een perspectief op de veerkracht van kinderen (Enthoven, 2007) bieden een kader om naar dit vraagstuk te kijken. Het onderzoek richt zich op wat het primair onderwijs kan doen om de aan de omgeving gerelateerde vermogens van kinderen te ontwikkelen. Onderwijs waarin de leefomgeving van kinderen wordt betrokken of waarin de leefomgeving op enige wijze een rol speelt kan hiertoe een middel zijn. Dit vanuit de notie dat door het ontwikkelen van een ‘sense of place’ (Dolan, 2016) de kennis, persoonlijke verbondenheid en verantwoordelijkheid voor de lokale omgeving versterkt kunnen worden. Het onderzoek zal na een verkennende fase een ontwerpgericht karakter krijgen, waarbij op onderzoeksmatige wijze materiaal wordt ontwikkeld dat bruikbaar is op basisscholen en lerarenopleidingen basisonderwijs.
