This paper reports the findings of a major national research project examining the use of multiple modes of delivery in Australian universities. A variety of factors including the increased use of online educational technology has pushed Australian universities in recent years to extend the ways in which they deliver learning and teaching. However, the extent of the uptake of these modes of delivery has remained somewhat unclear as have the precise reasons why universities have adopted multiple modes. The paper reports the result of a survey which clarifies the extent of the use of multiple modes of delivery in Australian universities and case study research that attempts to unpack the reasons for adoption. The research finds that traditional face to face delivery is still the dominant form of delivery but universities are experimenting with a surprisingly wide variety of alternatives.
