The purpose of this study was to establish the Influence of Teaching Methodology on Student's
Academic Performance in Physics in Secondary Schools in Lang’ata Sub-County, Nairobi
County. The Study sampled 126 respondents using both random and purposive sampling
methods. The study established that most physics Teachers were experienced in teaching Physics
having taught for more than 1-5 years. This could positively undermine the effective teaching of
Physics. Generally, Physics resources were found to be inadequate in terms of laboratories,
equipment, textbooks and library resources while teaching and learning resources are rarely
updated and this implies that the Schools were using outdated teaching materials. However, most
Physics Teachers find it difficult to prepare their lesson plan on time. The study, therefore,
recommends Ministry of Education should continue to equip schools with the latest Physics
teaching and learning resources, and Teachers should take less workload to have ample time to
prepare for their lessons. Adequate and up-to-date Physics textbooks should be provided
including trained Physics Teachers. School administration should offer adequate supervision to
physics teachers to ensure that they deliver the content of physics and cover the syllabus at an
appropriate time. And Students are encouraged to continue to study hard to maintain good
performance in physics.
