- © 2020 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Ocean Acidification (OA) is an emerging environmental issue that is still largely unknown to the public and in its infancy in terms of educational strategies. OA teaching material should address the specific challenges that educators face while building learners’ understanding of OA. The objective of this study is two-fold. First, we identified the barriers to teaching OA as experienced by formal and informal marine educators. Second, we provided educators an opportunity to experience virtual reality and discuss how it could serve as a tool for face-to-face and distance learning to address the identified challenges. The findings shed light on four overarching themes of challenges to teaching OA: lack of science literacy, unprepared education field, complex and invisible nature of OA and lack of personal connection with the ocean. Marine educators consider empowerment, perspective-taking and visualization as the three principal avenues through which virtual reality may contribute to mitigating the challenges to teaching OA.

Tidskriftsartikel (refereegranskat)abstract
- In this article, 61 high-school students learned about ocean acidification through a virtual laboratory followed by a virtual lecture and an asynchronous discussion with a marine scientist on an online platform: VoiceThread. This study focuses on the students' development of ocean literacy when prompted to ask questions to the scientist. The students' questions were thematically analysed to assess (1) the kind of reasoning that can be discerned as premises of the students' questions and (2) what possibilities for enhancing ocean literacy emerge in this instructional activity. The results show how interacting with a scientist gives the students an entry point to the world of natural sciences with its complexity, uncertainty and choices that go beyond the idealised form in which natural sciences often are presented in school. This activity offers an affordable way of bringing marine science to school by providing extensive expertise from a marine scientist. Students get a chance to mobilise their pre-existing knowledge in the field of marine science. The holistic expertise of the marine scientist allows students to explore and reason around a very wide range of ideas and aspect of natural sciences that goes beyond the range offered by the school settings.

Tidskriftsartikel (refereegranskat)abstract
- This research explores and adds to the literature concerning the relationship between spatial structure and travel behaviour; specifically, the relationship between local and regional accessibility to service amenities and the distance of service-related trips. The analysis is based on a unique combination of national travel survey data for Sweden and official register data with detailed, geo-referenced information about the Swedish population and the location of service amenities in 1995 and 2005/2006. The results show that spatial access to service amenities increased in general over the study period, both locally (i.e., within ranges of 1 km and 5 km, respectively, of residential areas) and regionally (within 50 km). Despite increased spatial accessibility, the observed average travel distance also increased. We find strong and differing associations between spatial access to service amenities and travel distance, depending on level of scale. While the association was negative on the local scale (i.e., a numerically large supply of amenities was related to shorter travel distance), it was the opposite and positive, on the regional scale. In terms of implications for policy, the results imply that land use planning measures to promote local access, and thereby reduce traffic volumes, may per se be insufficient for attaining more sustainable levels of mobility.

Konferensbidrag (refereegranskat)abstract
- This paper describes a system to create animated 3D scenes of car accidents from written reports. The text-to-scene conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual, simulator generates and animates the scene. We outline the overall structure of the text-to-scene conversion and the template structure. We then describe the information extraction system: the detection of the static objects and the vehicles, their initial directions, the chain of events, and the collisions. We show snapshots of the car animation output and we conclude with the results we obtained.
