The Effects of Sheng’ Vocabulary Usage in the Learning of Kiswahili Grammar in Public Secondary Schools in Kenya

Purpose: Sheng’ is a linguistic code based primarily on the Kiswahili structure and grammar with the lexicon drawn from Kiswahili, English and the various ethnic languages of Kenya; that are mostly spoken in towns and other urban areas. The purpose of this paper was to examine the effects of Sheng’ vocabulary on the learning of Kiswahili grammar in public secondary schools in Kenya. Methodology: Krejcie & Morgan sampling table was used to sample the schools. Stratified random sampling, simple random sampling and purposive strategy were used to sample the public secondary schools to participate. Krejcie and Morgan sampling table was used to sample 55 teachers of Kiswahili and 360 students to take part in the study. Data was collected using observation schedules, focused group discussion guides and a writing task for students. Questionnaires and interview guides were used for teachers of Kiswahili. Qualitative data collected was analyzed thematically to generate information that was summarized in graphics and discussed in narrative form. Quantitative data was analyzed with the help of Statistical package for social Studies. Findings: The findings of the study further revealed that Sheng’ vocabulary influenced written Kiswahili grammar as learners wrote Sheng’ words whereas they were expected to write standard Kiswahili. Unique Contribution to Theory, Policy, and Practice: School administrators should come up with a school-based language policy so as to control learners’ language environment. The ministry of education should encourage the culture of drama, music and debate competition among schools. The Kenya Institute of Curriculum Development should also ensure language use is stipulated in Kiswahili curriculum and Sheng’ be considered as an independent language code in the country.
