The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.
