- Description: The reform and transformation of education systems in terms of enhancing Science, Technology Engineering and Mathematics (STEM) education in the schooling systems is gaining momentum in different parts of the world. It is argued that there is a need to enhance science education, particularly in Africa, because science education is considered to be the main vehicle through which the greater objectives such as national development and improvement in the quality of life can be realised. Namibia as a country is no exception. A key way through which science education can be enhanced is through carrying out practical activities during teaching and learning. Despite the crucial role that practical activities play in science subjects, it appears that they are not carried out in most of the Namibian science classrooms. It is against this background that this study explored an intervention on how easily accessible resources to carry out hands-on practical activities in science, influenced science teachers’ conceptual development and dispositions towards the use of practical activities in science. In this study, a mixed methods case study approach underpinned by an interpretive paradigm was adopted. The research was conducted with 21 in-service science teachers from schools in Namibia who were all on a two year part-time BEd (Honours) program delivered in Namibia by a South African university from the Eastern Cape. To generate data, document analysis, questionnaires, semi-structured interviews, an intervention in the form of workshops on practical activities, lesson observations, which were videotaped, as well as teacher reflections were used. Conceptual development, disposition and professional development served as the conceptual lenses. Vygotsky’s sociocultural theory in conjunction with Shulman’s pedagogical content knowledge (PCK) were the theoretical frameworks adopted in the study.The findings showed that there was a general perception among the participants before the intervention that in order to carry out practical activities, well-equipped laboratories, conventional chemicals and equipment are needed. Some teachers had never used practical activities in their science classes with a range of constraints or hindrances provided as reasons. The findings additionally showed that for teachers to use easily accessible resources to carry out practical activities in their science classrooms, they need the knowledge and exposure on how to use these resources. The findings thus showed that this professional development approach raised motivation, knowledge and the skills of the science teacher participants to include practical activities in their science lessons using easily accessible resources. A recommendation is that if teachers are given opportunities, through professional development platforms to engage in hands- on practical activities using easily accessible resources, they can be enabled and motivated to implement these in their science classrooms.

- Description: It has been observed that the teaching and learning of the concept of rates of reactions is seen as being difficult for most Namibian learners. Concerns have been expressed in Examiners’ Reports about candidates showing little knowledge of the topic ‘rates of reactions’. Hence, this study sought to explore how indigenous knowledge and practices through a practical activity of making oshikundu, enabled or constrained learner-engagement and sense-making of the concept of rates of reactions in Namibian schools. Underpinned by an interpretive paradigm, the study tried to describe and understand how learners make sense of their world. Within the interpretive paradigm, a mixed-method case study approach was adopted. It is informed by Vygotsky’s socio-cultural theory, which recognises that learning and meaning-making are represented as originating from social interactions among individuals. The research study was conducted in a rural secondary school in the northern part of Namibia with Grade 11 Physical Science learners. Purposive sampling techniques were used to select three learners from the class, as the interview sample. A pre-test was used to gather data on the type of prior knowledge that Grade 11 Physical Science learners had of concepts related to rates of reactions. The pre-test’s content was validated by two Physical Science specialists. Observations were used to explore how learners make sense of rates of reactions during lessons. In addition to observations, interviews and a post-test were used in order to gather data on how the practical activity of making oshikundu enabled or constrained Grade 11 Physical Science: (a) learner engagement and (b) sense-making of the concept of rates of reactions. The findings of the study found that learners were more engaged and participated more fully in class than in previous year when the indigenous practice of making oshikundu was incorporated during the science lessons. The study thus recommends that indigenous knowledge and practices be integrated into Physical Science classrooms for effective teaching and learning and sense making of science concepts.
