Abstract
Teacher effectiveness remains a central determinant of educational quality and learner achievement in primary education. This study examined the influence of teacher motivation on teacher effectiveness in public primary schools in Lang’ata Sub-County, Nairobi County, Kenya. The study adopted a mixed-methods approach, integrating a correlational research design for the quantitative component and a phenomenological design for the qualitative component. The target population entailed 1,200 respondents, comprising teachers, Grade 8 learners, and deputy head teachers, from which a sample of 300 respondents was selected using stratified and purposive sampling techniques. Data were collected using structured questionnaires and semi-structured interview guides and analyzed using descriptive and inferential statistics alongside thematic analysis for qualitative data. Upon analysis, the study revealed a moderate positive relationship between teacher motivation and teacher effectiveness, r(98) = 0.396, p < .001. The results further showed that teacher motivation enhances teacher–learner relationships and promotes collaboration among teachers, leading to increased job satisfaction, confidence, and a supportive school climate that strengthens instructional quality. The study concludes that teacher motivation is a critical determinant of teacher effectiveness and plays a significant role in improving teaching practices and learner outcomes in public primary schools.
Keywords: Teacher motivation, teacher effectiveness, public primary schools, instructional quality, professional commitment, classroom performance, learner outcomes.
