Impact of Motivation on Teachers' Job Performance in Niger State, Nigeria

This study investigated the impact of motivation on teachers' job performance in Niger State, Nigeria, using two dimensions of motivation, namely: intrinsic motivation and extrinsic motivation. Extrinsic motivation was conceptualized broadly in this study to capture both the material and structural incentives that an employer provides, such as salary, promotion, and recognition, and the physical and social conditions under which teaching and learning occur, such as classroom facilities, supervisory support, and school climate, consistent with the hygiene component of Herzberg's two factor theory. Intrinsic motivation on the other hand refers to motivation that originates internally in the form of a person's interests and goals. The study adopted a quantitative, cross sectional survey design. The total population of the study consisted of 6200 teachers obtained from the 25 Local Government Areas of Niger State distributed in the 3 senatorial districts of Niger-East, Niger-North and Niger-West. A multi stage sampling technique was adopted: the first stage involved stratifying the twenty-five local government areas by senatorial district, the second stage involved the random selection of a proportionate number of schools within each stratum, and the third stage involved the simple random selection of individual teacher respondents within the selected schools. The sample size was determined using the Taro Yamane formula, expressed as n = N / (1 + N(e)²), where n represents the required sample size, N represents the target population, and e represents the margin of error, set conventionally at 0.05 (Yamane, 1967). Applying this formula to the population of six thousand two hundred teachers yields a computed sample size of approximately three hundred and eighty (380) respondents. The instrument used for data collection produced a reliability index of 0.75. The research questions were answered using descriptive statistics, including mean, standard deviation and frequencies, alongside inferential statistics, specifically multiple regression analysis, to test the two null hypotheses at 0.05 level of confidence corresponding to the two motivational dimensions. The findings of the study indicated that both dimensions of motivation exert a positive and statistically significant impact on teachers' job performance, with extrinsic motivation, inclusive of the work environment, showing the strongest predictive weight. The study concludes that a deliberate, balanced motivational policy that addresses intrinsic fulfilment alongside extrinsic motivation-material incentives, the physical teaching environment; is necessary to sustain teachers’ job performance in Niger State. Recommendations are offered for the State Ministry of Education and the Universal Basic Education Board as well as School Managers/Administrators.
