Motivation has been studied by different scientists in different fields of knowledge such as biology, psychology, and education for a long period, which has cultivated a wealth of knowledge in these disciplines. The richness in motivation theories poses complexity in motivation research. Due to these complexities, many researchers focus on using a single motivation theory in their studies. Using multiple motivation theories in a singular study is not a common practice in education research. This study presents a unifying framework for approaching motivation research in education which offers an opportunity to use multiple motivation theories in educational research, and other disciplines.
