    BeeLife : a mobile application to foster environmental awareness in classroom settings
    (2024) Stock, Adrian; Stock, Oliver; Mönch, Julia; Suren, Markus; Koch, Nadine Nicole; Rey, Günter Daniel; Wirzberger, Maria
    Introduction: Significant threats to our environment tremendously affect biodiversity and related gains. Particularly wild bees actively contribute by pollinating plants and trees. Their increasing extinction comes with devastating consequences for nutrition and stability of our ecosystem. However, most people lack awareness about those species and their living conditions, preventing them to take on responsibility. Methods: We introduce an intervention consisting of a mobile app and related project workshops that foster responsibility already at an early stage in life. Drawing on principles from multimedia learning and child-centered design, six gamified levels and accompanying nature-based activities sensitize for the importance of wild bees and their role for a stable and diverse ecosystem. A pilot evaluation across three schools, involving 44 children aged between 9 and 12, included a pre-, post-, and delayed post-test to inspect app usability and learning gains. Results: Most children perceived the app as intuitive, engaging, and visually appealing, and sustainably benefited from our intervention in terms of retention performance. Teacher interviews following the intervention support the fit with the envisioned target group and the classroom setting. Discussion: Taken together, the obtained evidence emphasizes the benefits of our intervention, even though our sample size was limited due to dropouts. Future extensions might include adaptive instructional design elements to increase observable learning gains.

    Analysis of the microclimatic and biodiversity-enhancing functions of a living wall prototype for more-than-human conviviality in cities
    (2023) Bornschlegl, Sebastian; Krause, Pia; Kropp, Cordula; Leistner, Philip
    This study analyzes the growing trend of urban green infrastructures, particularly green façade systems, in terms of their infrastructural relationships between nature and culture and their potential to act as bioclimatic layers mediating between the needs of flora, fauna and human habitation. An interdisciplinary approach is taken by combining the perspectives of social and engineering sciences to discuss the contribution of green façade systems for more-than-human conviviality in cities. Green infrastructures can support this endeavor by enabling functions that help to integrate the heterogeneity typical for semi-natural structures into urban ones, especially regarding microclimatic and biodiversity-enhancing functions. The theoretical distinction between “gray”, “green”, and “revolutionary” infrastructure is used to differentiate between conventional and posthumanist conceptualizations of urban naturecultures. The performance of the UNA TERRA living wall prototype as a green and revolutionary infrastructure is evaluated. The results show that the living wall has beneficial microclimatic effects and adds a heterogeneous habitat structure that supports biodiversity in the urban context. By adhering to “egalitarian humility” in design, the uncertainty and openness of more-than-human conviviality are acknowledged. The study finds that green infrastructures such as green façade systems can fulfill the criteria of revolutionary infrastructure if the contribution to local biodiversity and structural complexity is prioritized and the heterogeneous interrelations between human and non-human actors are taken into account.

    Exploring smart grids with simulations in a mobile science exhibition
    (2015) Li, Huijie; Chabay, Ilan; Renn, Ortwin; Weber, Andreas; Mbungu, Grace
    Improving the publics' understanding of the energy system is a challenging task. Making citizens aware of how the complex energy system functions and how consumers of energy services can respond to a changing energy environment seems more difficult. In the context of the German energy transition, more active energy consumers are needed, not only in producing electricity on their own but also interacting with suppliers to make the energy system operate in a more efficient way through the development of a "smart grid". This article describes an approach taken with a public education perspective to engage citizens in thinking about the issues we are facing in moving toward a future with greater reliance on renewable energy. We introduced a mobile exhibition, including an interactive simulation game, which offered a perspective on the whole energy system. The goal was to stimulate questions and arouse citizens' interest in learning about the smart grid and help them to prepare for the transition to a smarter way of using energy.
