How puzzles are shaping our understanding of biodiversity: A call for more research into biodiversity representation in educational games

Games as a didactic tool (e. g., puzzles) are gaining recognition in environmental education to promote skill development, but also to develop a specific understanding of the natural world. However, a children’s puzzle containing representations of nature may unwillingly lead to “misconceptions” of biodiversity themes and processes, and an over-simplification of the relationship between people and nature. To solve this problem, positive connotations of biodiversity may prompt a conceptual change to a more nuanced, multifaceted conception of biodiversity

How might everyday experiences shape biodiversity understanding? A perspective to spark new research

In this perspective article we start from the theories of constructivism and conceptual change within the field of education to develop and present hypotheses about how understandings of biodiversity and diversity more generally are formed. We argue that extrinsic and circumstantial elements from everyday experiences are relevant in shaping understandings of biodiversity. We discuss how children’s games and food-related experiences may influence how children form conceptions of biodiversity. We focus on ‘misconceptions,’ areas where conceptions differ from established ideas in ecology. These include: underestimating the importance of diversity for “complementarity” and over-simplifications of how nature works. Firstly, we examine a type of children’s game that often concerns biodiversity and consists of a puzzle where the forming of categories is encouraged. Secondly, we discuss people’s relation to nature through food in their diets. We believe that targeted intervention is needed to move towards an inclusive and multi-faceted representation of biodiversity, one that emphasises fundamental properties that make a whole and interacting parts. We argue that experiences of games and food can be pivotal in developing a deeper understanding of these fundamental properties of biodiversity. These would be important experiences to consider when attempting transformative change of relationships between people and nature

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
