Bridging traditions: mobilising indigenous knowledge and marine biodiversity conservation to support learner talk and sense-making in Grade 11 Life Sciences

Abstract

The Curriculum Assessment Policy and Statement (CAPS) document mandates that science teachers should integrate learners' Indigenous Knowledge (IK) into their classrooms. However, many South African teachers, like those in Namibia, seem to struggle with this integration due to insufficient pedagogical content knowledge, leading to minimal IK integration and hence poor science performance. This issue suggests that science curricula seem to lack clarity on integrating IK. It is against this backdrop that I was motivated to mobilise marine Indigenous Knowledge to support Grade 11 Life Sciences learners from a township school to talk and make sense of marine biodiversity conservation. A qualitative case study research design was used as it permits the grouping of detailed information essential to making sense of the anticipated responses of the participants. This study was informed by Vygotsky's sociocultural theory and Cultural-Historical Activity Theory (CHAT). It was conducted at a township school in the Eastern Cape, South Africa. Forty-five Grade 11 Life Sciences learners, two Indigenous Knowledge Custodians (IKCs) who grew up in marine environments and a local fisherman were participants in this study. Additionally, I asked one science teacher to be a critical friend. Data sets were gathered using a group activity, focus group interviews (sharing circles), observations (participatory and lesson observations), stimulated recall interviews and learners' reflections. The sociocultural theory was used as a lens to find out how learners learn through social interactions and how learning takes place in a sociocultural context. I augmented this theory with CHAT as an analytical framework. The CHAT provided an analytical lens to understand how community involvement and IKC interventions supported learner talk and sense making of the content and facilitated meaningful learning. The main findings of the study revealed that during the IKCs' presentations, learners were able to identify science concepts embedded in the Indigenous Knowledge of marine biodiversity conservation. The findings further revealed that the presentations stimulated learner talk and improved sense making among learners regarding marine biodiversity conservation and related concepts. The study recommends that teachers should leverage IKCs' cultural heritage by inviting them into classrooms to make science more relevant, accessible and meaningful for learners.
