Effectiveness of English language textbook in developing Oral communicative competence of high school students

This study aimed to evaluate the revised English textbook "Comprehensive English Book One for Class XI" prescribed by the Sindh Textbook Board for its effectiveness in fulfilling the language needs of ESL students in Pakistan, particularly in developing oral communicative competence (OCC) of high school students. Using an interpretivist approach, the research adopted a qualitative method, employing semi-structured interviews with thirty participants-ten teachers and twenty students, purposively selected, along with participant observations. Data from these sources were analyzed using thematic analysis, ensuring validity and reliability through methodological triangulation. The findings indicated that the revised textbook was highly effective in enhancing students' oral communicative competence. However, a major issue identified was the improper classroom implementation of the textbook, undermining its overall effectiveness. The study highlights the need for improved ESL teaching practices in Pakistan, and contributes to existing literature on textbook development. It recommends capacity-building measures for teachers to optimize the use of teaching resources and ensure effective implementation of the revised textbook.
