ABSTRACT This article explores the nexus among research methodlogy, classroom data and instructional policy enactment through content analysis of lesson transcripts. It is a multiple-case research of four Zimbabwean secondary school geography teachers’ classroom practices. Coded lesson-transcripts and post-lesson teacher-interview transcripts subjected to thematic content analysis yeilded patterns of classroom interaction. Most lessons were teacher dominated question and answer episodes which failed to achieve mandated learner-centred teaching.Teachers relied on recall-type questions while failing to scaffold onto learner contributions for deeper geographical conversations. A weak pedagogical content knowledge partially contributed to this. Content analysis of lesson transactions showed a symbiotic nexus among research methodology, classroom data and instructional policy implementation. Coded classroom data holds opportunities for critcal scrutiny of classroom transactions to gauge instructional policy implementation. Findings suggest succesful instructional policy implementation can benefit from teacher training in content analysis of classroom transactions for reflexive practice.
