Critical thinking (CT) has been emphasized as a key competence in education, and one of the most central competences to promote in sustainability education (SE) (EU Commission, 2016; Vare & Scott, 2007). CT is regarded an essential competence to be able to contribute to a sustainable society (Rieckmann, 2017), and considered a vital part in building up students’ action competence for sustainability (Schnack, 1998). In 2007, Vare & Scott pointed to the need to strengthen the focus on CT in SE, and CT as an area of development in education is yet still emphasized (Munkebye & Gericke, 2022; Frønes & Jensen, 2020). Studies have shown that teachers consider CT to be a central aspect of SE, however, there is a need for professional development to further teachers’ abilities to teach CT generally (Hasslöf & Malmberg, 2015; Frønes & Jensen, 2020), and specifically in relation to complex sustainability issues (Munkebye & Gericke, 2022).
CT has been defined in varying ways over time, however, there is a broad consensus that CT includes skills and dispositions (Lai, 2011; Facione, 1990). Skills concern elements such as e.g. analyzing, evaluating and problem-solving, and dispositions include e.g. fairmindedness, openmindedness and desire to be well informed (e.g. Lai, 2011, Facione, 1990). It is also argued that developing those elements is not sufficient; being a critical thinker also includes the concept of criticality, i.e. to exert CT in situations that call for it (Davies & Barnett, 2015). This is of importance when dealing with complex sustainability issues, which brings important implications for SE. Moreover, skills include cognitive components whereas dispositions generally are associated with the affective domain (Facione, 1990). Including dispositions may be important for developing CT that includes ethical considerations.
Sustainability issues are characterized by great complexity and often great uncertainty (Block et al. 2019). To find solutions that simultaneously benefit the environmental, social and economic dimensions that sustainability issues entail are often difficult (Öhman & Öhman, 2012). Vare & Scott (2007) emphasize the need to include activities that allow students to explore the contradictions inherited in sustainability issues. This makes sustainability a fruitful learning context for the development of CT, and equally important, CT becomes one important learning outcome of SE. A large-scale study from Sweden showed that students who experienced teaching that focuses on a multitude of perspectives and critical approaches to these also display a higher level of actions that promote sustainability (Boeve-de Pauw et al., 2015).
Several studies have shown that teachers often pursue an environmental perspective of sustainability, which implies a risk that the complexity is lost (Sund & Gericke, 2020; Borg et al. 2014). The opportunities for developing CT in SE might then be reduced. The study by Munkebye & Gericke (2022) indicated that teachers in Norwegian primary school associate CT to SE. However, both affective elements and interdisciplinary strategies were excluded from their teaching. Possibly, there is a risk that CT is taught without inclusion of ethical perspectives. Studies have found that teachers recognize the importance of CT, but many lack deeper understanding of what CT comprises and they often feel unprepared to teach it (Schulz & FitzPatric, 2016).
Many studies on competences in relation to SE are carried out within higher education. Against this background, the present study aims to identify what skills and dispositions primary school teachers relate to when they reflect on CT. The research is conducted within the CriThiSE-project, which aims to develop teaching of CT within SE. The research questions are:
- How do primary school teachers perceive the concept of CT?
- How do primary school teachers perceive CT in relation to their teaching?
