This study examines implementation of learner-centred methods (LCMs) within the constraints of shortage of instructional resources and facilities. Qualitative multiple case study research design was used to obtain data from 103 respondents. Data were collected through interviews, documentary review, focus group discussions and observations. Data from interviews and documentary review were analysed by content analysis and that from observations were analysed through drawing meaning by inference. This study reveals that strategies teachers used to implement LCMs within the shortage of instructional resources and facilities are functioning to improve students’ performance. The findings show students increase the morale of studying and confidence hence raises their ability to grasp the intended knowledge. The findings also disclose that, the major cause of shortage of instructional resources and facilities is lack of funds for buying gears for LCMs like books, computers, projectors, and printers. Moreover, it was revealed that teachers view LCMs as the best methods, however, close supervision of curriculum is advised. Also, teachers should be trained to enable them to apply LCMs in an effective way and increase of funds for the schools was advised. It is recommended that it is worthwhile to ensure that all key educational stakeholders play their roles, without which good teaching methods will always remain on papers. Teaching using LCMs should be achieved in its implementation. The study concludes that the application of LCMs in secondary schools is apparent and important, but there should be a serious improvement for better results from these methods.
