Abstract

It has been shown that many people do not understand how scientific knowledge is built and accepted, even after scientific education. One way to deal with this problem is through teaching about the Nature of Science (NOS). NOS can be understood as a pedagogical construct aiming to foster the understanding of the main characteristics of scientific work. Recently, several researchers have advocated that we should consider pluralism within science when teaching about NOS. Accordingly, there have been efforts to develop ways of promoting instruction on NOS considering the specificity of distinct scientific fields. Aligned with this perspective, this paper aims to put forward a model for teaching NOS in the context of biological education. This model, named “Integrative Model for Teaching NOS in Biological Education” (IM-NOSBIO), is based on three pillars. The first is the Family Resemblance Approach to Nature of Science (FRA), developed by Erduran and Dagher. The second consists in the Conceptual Framework of Biology proposed by Scheiner. The third is the Pragmatic Conception of Models as Epistemic Artifacts put forward by Knuuttila. We propose that IM-NOSBIO has the potential to promote teaching and learning about different aspects of scientific knowledge and practice by taking advantage of how they present themselves in biological sciences teaching. To illustrate this potential, we offer an example of how this model can be used for teaching about certain aspects of NOS based on the history of the cell theory.

Notes

  1. Generally speaking, “scientific practices” refer to the cognitive, epistemic, socio-institutional, cultural, and other processes carried out by scientific communities to build scientific knowledge. To include scientific practices in NOS teaching runs counter presenting science as just a body of knowledge, as it is often the case in science education.

  2. We use “academic scientific knowledge” here to refer to Western scientific knowledge as typically built and validated in academic institutions around the world. We leave it open whether some other knowledge systems can be described as ‘scientific’ too, such as, say, indigenous sciences (see, e.g., Snively & Corsiglia, 2001; Bicker et al., 2003; Brayboy & Castagno, 2008; Alessa et al., 2016). This is a point of contention in anthropological, philosophical, educational, and scientific literature that we do not intend to settle here. Thereafter when we use “scientific knowledge,” we keep the same reference as in “academic scientific knowledge,” but do not include “academic” just for the sake of simplicity.

  3. According to Pigliucci (2013a, p. 766), pseudoscience “refers to a highly heterogeneous set of practices, beliefs, and claims sharing the property of appearing to be scientific when in fact they contradict either scientific findings or the methods by which science proceeds.” Notice that a pseudoscientific position cannot be simply conflated with a non-scientific one. For instance, if a religious writer argues for creationism and does not intend it to be treated as a scientific position or included in the science curriculum, it is not justifiable to qualify his or her arguments as “pseudoscientific,” as they are just different from scientific ones, just “non-scientific.”

  4. These factors include worldviews, religious beliefs, and personal values (Alters & Alters, 2001; Lawson & Worsnop, 1992; Osif, 1997; Tracy et al., 2011); psychological, political, and social factors (Allmon, 2011; Tracy et al., 2011); and epistemological beliefs and cognitive dispositions (Sinatra et al., 2003).

  5. It is quite common to find in the literature the use of other expressions to refer to individuals’ conceptions about science, such as correct, incorrect, adequate, inadequate, and naive. However, we recognize the difficulty of using them without sounding like a derogatory evaluation. To work around this problem, in this paper we will use adjectives such as “informed” and “sophisticated” to refer to individuals’ views about science. We think that using these adjectives decrease the tendency to disparage or belittle someone’s views about scientific work, when compared to qualifications such as “incorrect” or “inadequate.” Consider, for instance, that claiming that a student became after learning about NOS more informed or more sophisticated in his or her views entails judging only that he or she had previously less informed or less sophisticated views, which could, nonetheless, be also correct or adequate.

  6. Among the various approaches found in the literature, we can also mention what has been called “the consensus view” on NOS (Irzik & Nola, 2011; Martins, 2015), or “tenets-based,” or “general aspects” conceptualization of NOS (Kampourakis, 2016) or, else, the “ideas-about-science” view (Osborne et al., 2003); the “Whole Science” perspective (Allchin, 2011, 2017); the “approach based on ‘themes’ and ‘questions’” (Martins, 2015); and the “Features of Science” (FOS) view (Matthews, 2012, 2015).

  7. For a criticism of the fundamental principles of a theory of biology proposed by Scheiner (2010), see Pigliucci (2013b). For a brief discussion of Pigliucci’s criticism, see Carvalho et al. (2020).

  8. According to Knuuttila (2005a, p. 49), the term “material” means “something that is concrete and corporeal, occupying space and time and able to interact with other things and human beings”.
