Abstract

In the evolving landscape of secondary school science education in Namibia, there is a growing shift from traditional rote-learning methodologies toward inquiry-based instruction and practical work to foster deeper learner engagement and critical thinking skills. This study, utilizing a sequential explanatory mixed methods approach, investigates the perceptions and practices of Namibian secondary school teachers regarding the implementation of inquiry-based science education. Despite the national curriculum's strong endorsement of learner-centered approaches, findings indicate a discrepancy between policy aspirations and classroom realities. Many teachers continue to rely on traditional methods due to persistent challenges such as inadequate resources, insufficient professional development, and entrenched instructional habits. However, those teachers who have adopted inquiry-based strategies report enhanced student engagement and a more profound understanding of scientific concepts among learners. This paper underscores the necessity for targeted professional development and resource allocation to bridge the gap between educational policy and practice, ultimately aiming to enrich science education through effective inquiry-based learning environments.

Abstract

This study evaluated the teaching of Physical Science practical work at a resource-constrained secondary school in the Rundu Circuit, Kavango East region in Namibia. The research objectives were to assess the impact of practical work on learners’ academic performance in a resource-constrained community, identify the challenges faced by both teachers and learners in conducting practical activities, and propose strategies to address these challenges and improve the overall quality of science education. A qualitative research design was employed, with data collected through semi-structured interviews involving four Physical Science teachers. The interviews were analyzed using thematic analysis, with themes aligned to the research objectives. The findings revealed that the state of science practical work was poor due to a lack of sufficient laboratory equipment and resources. Other significant challenges identified included limited laboratory space, inadequate time allocation, overcrowded classrooms, a lack of motivation among learners, and insufficient background knowledge on practical work for learners. These challenges collectively impeded effective teaching and learning of science practical work. To overcome these issues, the study recommended providing adequate laboratory materials and constructing an additional laboratory to alleviate overcrowding. The study also further recommended the employment of laboratory technicians to assist teachers in organizing, planning and conducting practical activities more efficiently. Furthermore, the study suggested forming partnerships between schools to share laboratory facilities, as per Key Area 7 of the National Standard and Performance Indicators for Schools in Namibia, which emphasizes the importance of collaborative linkages within educational communities. By implementing these strategies, it was concluded that the quality of Physical Science practical work in resource-constrained schools could be significantly enhanced, leading to improved learner outcomes.

Abstract

This quantitative classroom intervention study investigated the effectiveness of using mnemonics to enhance preservice teachers’ conceptual understanding of the topic of wave properties in physics. The study involved a sample of 30 final-year undergraduate preservice teachers enrolled in the Bachelor of Education Honours, Senior Primary with specializations in Natural Science and Health Education at Dorado Campus of The International University of Management in Namibia. The primary objective was to assess the impact of a targeted mnemonic-based instructional intervention on their ability to comprehend and apply key physics concepts related to wave properties. Initially, participants’ baseline understanding of these concepts was evaluated through pre-intervention assessments, which provided a measure of their existing knowledge. A structured mnemonic-based teaching intervention was then implemented over a specified period, designed to facilitate improved understanding of wave properties. Following the intervention, post-assessment evaluations were conducted to compare and measure changes in the participants’ conceptual understanding of the subject matter. This comparative analysis aimed to identify any significant improvements resulting from the mnemonic-based instruction. The findings indicated that there were notable improvements in the participants’ conceptual grasp of wave properties after the mnemonic-based intervention. Additionally, the study collected and analyzed participants’ feedback regarding the use of mnemonics, offering insights into their perceptions of the technique’s effectiveness as a pedagogical tool for learning complex scientific concepts. This research contributes to the broader field of physics concepts by providing evidence-based strategies to enhance the preparation of preservice teachers, particularly in physics education. Ultimately, the results of this study have the potential to inform and improve teaching practices, fostering more effective and engaging educational experiences in future science classrooms.
