- Description
- It seems code-switching from English to learners’ home language is a regular practice in Namibian schools. That is, science teachers mediate specific challenging science topics such as chemical bonding through code-switching from English to learners’ home languages. Based on anecdotal evidence and on Grade 10 Examiners’ Reports for previous years, chemical bonding is one of the challenging key concepts in Physical Science, and yet it is an important concept in the study of chemistry. Therefore, the purpose of this interventionist study was to investigate how the use of learners’ home language enables and/or constrains Grade 8 Physical Science learners’ sense making of the topic, chemical bonding. The study is a convergent parallel mixed method case study and was underpinned by an interpretive paradigm. It was conducted with 17 Grade 8 learners in a rural school, where I teach, in the Oshana region. I used a diagnostic test to elicit learners’ prior knowledge on this topic, a post-intervention test, observation, reflections, focus group interview and stimulated recall interviews as my data collection methods. I used Vygotsky’s (1978) Socio-Cultural Theory as my theoretical framework to help explain how learners make sense of the concept of chemical bonding when learners’ home language is used in a Physical Science class. To analyse the quantitative data obtained, I used a descriptive statistics and inferential statistics method. In the descriptive statistics, data were compiled into graphs, tables, and other visual representations, while for the inferential statistics, a t-test was used to establish the significant difference of the data collected. On the other hand, a thematic approach to analyse the qualitative data was employed to come up with sub-themes and themes. The findings of the study revealed that learners’ home language stimulates learners’ interest to learn new concepts, and enhances learners’ understanding and participation during the science lessons. Another finding of the study revealed that learners’ prior knowledge in chemical bonding contained some misconceptions. Furthermore, the findings of the study also revealed that learners learn best when their prior knowledge are elicited before they are introduced to new concepts in their science classrooms. The study recommends that learners’ home language should be incorporated into Physical Science lessons, especially when the teachers are teaching challenging concepts such as chemical bonding.
