The effect of a scientific literacy strategy on grade 6 and 7 learner's general literacy skills

In this study I investigated the effect of a science literacy strategy on the development of grade six and seven second-language learners’ general literacy skills in both their home language (isiXhosa) and language of instruction (English). The scientific literacy strategy used focuses on reading to learn science, writing to learn science, classroom discussion and argumentation. A mixed method design was used. Quantitative data were collected from baseline and post-testing of language skills of learners. Qualitative measures were generated through interviews of learners and teachers and classroom observations. The sample comprised of seven grades six and seven (multigrade classrooms) classes in seven primary schools situated in the rural areas near Hogsback in the Eastern Cape (five experimental schools and two control schools). Mean differences between the experimental and control groups for the reading, listening, writing and speaking aspects of the literacy tests were computed and the data generated were treated statistically using Analysis of Variance. The qualitative data were used to gain deeper insights into the quantitative results. The data suggest that the science literacy strategy statistically significantly improved the learners reading skills in English, their listening skills in both English and isiXhosa, and their writing skills in isiXhosa over a six-month period. Possible explanations for these results are that the reading material was in English only, extensive use of code-switching from English to Xhosa was made by the teachers while teaching, and that learner classroom discussion and writing in isiXhosa was encourage
