Linking teacher motivation to educational outcomes in secondary schools of Lusaka district, Zambia

Linking teacher motivation to educational outcomes is critical for informing policy and practice in resource-constrained settings such as Zambia. This study investigates the relationship between levels and dimensions of teacher motivation and student performance in secondary schools in Lusaka District. Utilizing a mixed-methods cross-sectional design, quantitative data were collected from 230 teachers using the Teacher Motivation Questionnaire to measure intrinsic and extrinsic motivational factors, and matched with the past three years of standardized examination scores from participating schools. Qualitative insights were gathered through semi-structured interviews with 24 teachers to explore contextual mediators of motivation - outcome linkages, including leadership support, resource availability, and professional development opportunities. Multiple regression and mediation analyses revealed that intrinsic motivation was a significant positive predictor of student outcomes (β = .42, p< .001), whereas extrinsic motivation showed a weaker but still significant association (β = .18, p = .045). Leadership support and access to instructional resources partially mediated the relationship between intrinsic motivation and academic achievement, accounting for an additional 11% of explained variance. Thematic analysis identified autonomy support, recognition, and collaborative learning as key drivers that enhance teacher engagement and efficacy. By integrating quantitative and qualitative methods, this research offers a comprehensive understanding of how teacher motivation influences educational outcomes within local socio-cultural constraints. Implications include the development of targeted professional development programs, the strengthening of school leadership practices, and policy recommendations for resource allocation to bolster teacher motivation. Limitations of the cross-sectional design and single-district focus are acknowledged, with suggestions for longitudinal and comparative studies across various Zambian regions. These findings extend self-determination and expectancy-value frameworks to a Sub-Saharan African context, highlighting the crucial role of intrinsic motivational factors and supportive school environments in driving student success.
