From the Systemic Functional Linguistics (SFL) standpoint, experiential meanings reflect our experience, perceptions, and consciousness. Research on experiential meaningmaking in tertiary contexts has traditionally focused on areas such as mathematics, journalism and media, science and computing, nursing, and history. This paper aims to investigate the experiential multimodal meanings in an undergraduate marketing course. The data comprised three written assignments and the tutor’s two model texts. The study employed a multidimensional approach by Alyousef (2013), which is framed by SFL (Halliday 2014) and O’Halloran’s (2005, 1998, 2008, 1999) multisemiotic framework for the analysis of semiotic codes in mathematics. The results showed that the experiential meanings in the students’ marketing plan texts were primarily construed through material processes and both explicit and implicit relational identifying processes. The findings indicated how mathematical symbolism is encoded in the multisemiotic texts, in the most economical manner, by using grammatical strategies of structural condensation. The results also noted the extent to which the different modes of meaning were integrated in the texts.


Growth will be defined as that attribute of living organisms which is manifested by a change of size of the individual, and we shall first consider growth formulae and curves. If y represents the size of any individual at time t , and if the growth process is regarded as continuous, we may define the absolute growth rate as dy/dt and the specific growth rate (which represents the change in y for change in time per unit amount of y ) as 1/ y dy/dt . Any statement which relates the size or growth rate of an organism to other variables will be called a growth formula; such statements are usually expressed in mathematical symbolism. Many growth formulae have been published and they have been derived by one of three methods.
