This is Richard Baker's (2017) dissertation study. Baker found 16 common experiences lived by TPRS teachers, 12 obstacles to overcome, and he made 4 recommendations for teachers to consider in their classrooms. His Chapter 2 includes an extensive and critical review of many related research studies done on this methodological approach. TPRS is a research-based, evidence-based, and research-validated method. It has been found effective for promoting classroom second language acquisition (SLA) in a variety educational contexts, for learning several different languages, and from pre-literate, to K-12, with gifted and special needs students, at the university, and with adult learners at every level of language teaching and proficiency. The data suggest that educators and administrators should 'support' and not block TPRS use. Baker believes educational leaders, once aware of the research, will support, and 'not resist' TPRS teachers.
