The document discusses the characteristics of good ESL teachers according to Allen (1980) and the author's views. The author selects three key characteristics: 1) critical thinking, as it allows students to develop their own responses and reasoning; 2) the persistent urge to upgrade oneself through continuous training, as it benefits teachers' knowledge; and 3) a feeling of excitement about one's work, as it motivates both teachers and students. The document also discusses whether Chilean teachers can be considered professionals according to Ur's definition, concluding they are developing in that direction, and defines action research as a reflective practice for teachers to identify classroom problems and improve teaching.
