Students' application of the concept of interdependence to the issue of preservation of species: Observations on the ability to generalize

Abstract

One of the aims of science education is that students should be able to apply scientific principles to contemporary issues. Individual interviews were used to investigate the way in which students (63 12‐year‐olds and 60 16‐year‐olds) applied the ecological concept of interdependence of species to the issue of preservation of species. Students were shown a list of items representing a range of living things and were asked to select those which they would want to save from extinction and explain their reasoning. Although most students used the concept of interdependence for some items, they did not apply it in a scientifically consistent way to all types of living things. Three probable reasons for this lack of consistency were anthropocentricism, mixed reasons (students appeared to spontaneously choose another type of reason depending on what image the item immediately provoked), and opposite reasons (students interpreted the idea of interdependence as applying to some types of living things but not to others).

Shark Conservation: An Educational Approach Based on Children’s Knowledge and Perceptions toward Sharks

“…Many studies have also revealed that students are used to considering environmental issues that have been highly simplified [ 33 , 35 , 38 , 40 , 41 ], leading to difficulty in grasping the concepts of mutual causality to explain complicated feeding relationships [ 37 , 38 ]. This echoes the finding that children apparently fail to consider environmental issues from a holistic perspective [ 37 , 40 , 42 ]. As suggested by Jordan et al [ 23 ], a deeper understanding of the interactions and connections could be promoted if the concepts of “systems and cycles” were enhanced.…”

Elevers uppfattningar av systemmodellering i arbete med hållbarhetsfrågor

“…Exempelvis har elever svårigheter att förstå underliggande kausalitet (Grotzer & Bell Basca, 2003) och koppla samman komponenter till ett komplext integrerat system (Favier & van der Schee, 2014;Jacobson & Wilensky, 2006;Karkdijk, 2022). Det har också visat sig vara utmanande för elever att urskilja indirekta interaktioner och deras effekter på systemnivå (Barman et al, 1995;Mambrey et al, 2020;Palmer, 1996). Elever tenderar att fokusera på omedelbara effekter samtidigt som de förbiser indirekta konsekvenser (Mambrey et al, 2020).…”

Defining and characterizing ecosystem services for education: A Delphi study

“…Viewing the environment as a place that exists for the benefit of humans affords prioritizing only those components of the environment that humans see as important. For example, when asked if specific endangered species should be saved, only 5% of sixth graders, and 32% of tenth graders supported saving all species (Palmer, ). Furthermore, even after learning about a keystone species (defined next), to which many students were originally apathetic, 80% of students ranked this species with a lower priority for conservation, preferring more charismatic species (Fox‐Parrish & Jurin, ).…”
