This paper presents theoretical foundations to investigate in what ways a metaphorical interface in Web-based instruction affects learning in terms of cognitive load. The previous study by the authors revealed there were no significant differences among three interface types. To ground a follow-up study, new theoretical frameworks of metaphorical interface and cognitive load are presented followed by implications for the future study. This paper explores systematic uses of a metaphorical interface and relationships between the functions of metaphorical interfaces and cognitive load types. In addition, the implications for the future study are proposed.
