The objective of this study is to establish an explicit understanding of the concept and dimensions of knowledge gap and knowledge expansion and as well reconcile the terminologies used such as research gap or research problem. Perhaps, the finding of this study is based on conceptual and theoretical reasoning from existing literature of knowledge gap and research gap. In exploring extant literature, the study shows that the concept of knowledge gap emanated from the mass media domain and has two distinct pillars or pathways such as differentials in awareness of issues and in depth informational issues about topics.
