Investigation into the relationship between intrinsic motivation, intrinsic rewards, extrinsic rewards and work engagement among teachers in South Africa

The primary objective of this mini-dissertation was to investigate whether a relationship exists between rewards, intrinsic motivation, work engagement among school teachers in South Africa. A further aim was to determine if work engagement has a moderating effect on the relationship between rewards and intrinsic motivation. The researcher further investigated whether demographic differences occurred across the three constructs studied. The study made use of quantitative research to achieve the above-mentioned objectives. The researcher made use of Ulrechs Work Engagement Scales (UWES), Intrinsic Work Motivation Scale (IWMS) and the Organisational Rewards Scale (ORS) to measure the mentioned relationships. The ORS was qualitatively piloted on a sample of primary school teachers in a Non-governmental institution. After refinement, a composite questionnaire was electronically completed by 207 teachers within South Africa. Data analysis was conducted in the form of descriptive and inferential statistics, including Cronbach’s alpha testing, Pearson’s Product Moment Correlations, t-tests, analysis of variance and structural equation modelling. The quantitative findings suggested that rewards lead to higher levels of Work Engagement, which in turn causes higher levels of Intrinsic Motivation. Thus, there was full mediation of rewards onto intrinsic rewards through work engagement From a demographics perspective, practically significant differences were discovered between NGO’s and Government High Schools for Rewards. In addition to these results, age differences were discovered across Work Engagement and job level differences were discovered for Intrinsic Motivation, together with significant correlations between the three constructs. These results theoretically contribute to the validation of the newly developed Intrinsic Work Motivation Scale. Furthermore, the results make a valuable contribution to the field of rewards management for teachers in South Africa
