Literature Review on MOOCs on Sensory (Olfactory) Learning

Massive Open Online Courses (MOOCs) have been described as a “next development of networked learning”, and they have the potential to mediate sensory learning. To understand this phenomenon, the present systematic review examines the research techniques, subjects, and trends of MOOC research on sensory learning, in order to provide a thorough understanding of the MOOC relevant to sensory (olfactory) learning phenomena by evaluating 65 (four studies are about multisensorial learning and 61 are about multisensorial empirical MOOCs researches) empirical MOOC studies published between 2008 and 2021 by searching through databases: PubMed, Scopus, Web of Science, and Google Scholar. The results indicated that most studies were based on quantitative research methods followed by mixed research methods and the qualitative research approaches; most of the studies were surveys, followed by platform databases and interviews; almost half of the studies were conducted using at least two methods for data collection: survey and interviews; most were replicated. The most highlighted subjects included student retention, learning experience, social learning, and engagement. Implications and studies into the future have been considered in order to obtain a more evolved understanding of the acquisition of knowledge through the senses.
