Analysis of Question Types and Their Effects on Oral English Performance in Secondary Schools in Kwara State

Question types used by English teachers during oral lessons have a direct and demonstrable effect on the quality and quantity of student oral production, yet the systematic investigation of this relationship in Nigerian secondary school contexts remains limited. This study analyses the types of questions used by English teachers in oral English lessons in Kwara State secondary schools and examines their differential effects on student oral performance. Twelve oral English lessons were observed across four secondary schools in Ilorin and its environs, with teacher questions coded using a display-referential-procedural classification scheme and student responses rated for length, complexity, and accuracy using a structured oral performance rating scale. Post-observation interviews were conducted with twelve teachers. Results confirm the strong predominance of display questions in all observed lessons, accounting for an average of eighty-one percent of teacher questions. Lessons in which referential questions constitute at least twenty-five percent of teacher questioning show significantly higher average student response length and complexity ratings. Teacher interview data reveal that most teachers view referential questioning as suitable only for advanced students, an attitude that effectively restricts richer oral interaction opportunities to better-resourced schools. The study provides lesson observation evidence challenging this view and recommends a state-level teacher training workshop series in Kwara State focused on diversifying classroom questioning repertoires.
