"The Learning Theories Profile" (LTP) supports professionals to locate various learning theories within four epistemological quadrants of the "Matrix of Perspectives." Professionals can use this tool to identify some of the theories they hold and to reflect on the alignment between their espoused theories and theories-in-use. Forty-four resource teachers used the LTP and demonstrated that they were guided by a range of theories, most commonly interactive theories. A strong relationship was observed between espoused and in-use theories. Participants' responses indicated the positive value of the LTP for supporting professionals to analyse and optimise interaction occurring in complex contexts of practice.
