Abstract

The Toulmin Model is introduced also to Japan, but in a unique way. While the original model consists of 6 elements, the model in Japan, called Triangular Logic Model, consists of 3 (claim, data, warrant). This paper discusses 1) the process of and reasons for the triangularization of the model and 2) pros/cons of this phenomenon. Though triangularization succeeds in making the model popular in educational practice, this (over)simplification lets the model go in the opposite direction to which Toulmin wanted to.
