Indigenous knowledge systems and science education

Open access
Blackie, Margaret A.L.·2024·South African Journal of Science

Abstract

The inclusion of indigenous knowledge into the curricula of natural science courses remains contentious.In this paper I use critical realism to show the relationship between these two forms of knowledge.An engagement with both knowledge structures could afford better pedagogy and assessment.In addition, the engagement with indigenous knowledge allows for the development of 'knower awareness' in the practice of science.Meaningful engagement with indigenous knowledge could therefore enhance science education, whilst making visible the socio-cultural relevance to students.

TL;DR

This perspective argues that indigenous knowledge systems (IKS) and Western science are related but not interchangeable, and that critical realism can clarify how they differ. It contends that careful engagement with both knowledge structures can improve science pedagogy, assessment, and “knower awareness,” while cautioning against treating IKS as equivalent to Western science where the latter operates at a conceptual explanatory level.

Key findings

  • Using critical realism, the paper distinguishes Level 1 science—careful observation and reproducible procedure, common to both Western science and IKS—from Level 2 science, where Western science seeks conceptual explanations of mechanisms; chemistry is described as primarily Level 2, so foregrounding IKS as equivalent to chemistry is “inaccurate and misleading.”
  • Engagement with both knowledge structures could afford better pedagogy and assessment, and meaningful engagement with IKS can develop “knower awareness” in the practice of science.
  • Including IKS can enhance socio-cultural relevance, motivation and self-esteem, cultural responsiveness, peer interaction, and positive learning experiences, and can help disrupt the image of the scientist as a white, heterosexual, cisgendered male and the notion that science is produced only by dead Europeans.
  • The paper locates IKS work across Bernstein’s three fields—production, recontextualisation, and reproduction—and focuses on the field of reproduction; cited examples include Xhosa-speaking soil classification in the Eastern Cape, isiZulu names for insects in KwaZulu-Natal, and Ovawambo clay pot making in Namibia.

Methods

  • Design: conceptual/perspective paper using critical realism and Basil Bernstein’s pedagogic device to analyse the relationship between IKS and Western science in natural science curricula.
  • Data or sample: no empirical sample or original dataset; the argument draws on cited examples and prior scholarship, including soil classification, isiZulu insect names, and clay pot making.
  • Main analysis: theoretical argument distinguishing Level 1 and Level 2 science and Bernstein’s fields of production, recontextualisation, and reproduction, with the major focus on the field of reproduction.

Limitations

  • Stated: the paper’s focus is limited to the incorporation of IKS into the natural sciences, and it explicitly says this does not mean IKS should be incorporated into every course.
  • Evident: the paper presents no empirical data, intervention trial, or systematic evaluation of outcomes; its claims are conceptual and illustrative.
  • Evident: the examples of IKS integration are drawn from other studies rather than from original research conducted by the author.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
