What is the point of interface between ESL and TPRS? It is the point where students are allowed to express themselves in human ways about human things. The point of interface is compelling personalization. The extent to which an ESL student is personally involved in developing the curriculum of an ESL class will determine the success of the class for him or her as a student.
ESL “curriculums” that focus on grammar and social studies topics cannot succeed. Teachers who force students to address those two things in speech and writing will always wonder why their students aren’t more involved in class. The reason they are not involved is that they are not involved as people and that they are being forced to be involved as robots. Change that and solve the puzzle.
