This research report, conducted by Janet Liliana Arciniegas Londoño at the Universidad de la Sabana, explores the use of podcasting as a tool to improve teacher trainees' ability to make proper sentence stress. The study involved 26 teacher trainees from the Universidad del Tolima, focusing on the concepts of andragogy, podcasting, intelligibility, and sentence stress. Data were collected through pre- and post-tests, surveys, artifacts, logs, and journals. The findings revealed that while the improvement in sentence stress was not significant, the students perceived the project positively, finding podcasting useful for self-assessment and enriching their future teaching practices. The report highlights the importance of technology in enhancing adult learning and the potential of podcasting in improving pronunciation skills.This research report, conducted by Janet Liliana Arciniegas Londoño at the Universidad de la Sabana, explores the use of podcasting as a tool to improve teacher trainees' ability to make proper sentence stress.
