This study investigated the relationship between task-based teacher training and novice English language teachers' cognitions and implementations of tasks in Honduran bilingual schools. After participating in a four-week training program on task-based language teaching, teachers with little or no prior teaching experience designed task-based lessons and were video-recorded implementing those lessons with English language learners ages 5 to 12. Following the classroom observation, teachers participated in a stimulated recall interview. A rubric aligned with 10 key principles of task-based language teaching (TBLT) as outlined by Long (2015) was used to rate teachers' performance and code stimulated recalls. Ratings of video observations showed varied success in TBLT implementation after training, with some teachers' lessons clearly aligned with key TBLT principles, and others relying on focus on forms strategies. Analysed data also uncovered a link between previous training and teaching experiences and the success of teachers' implementations. Stimulated recalls showed that teachers focused primarily on maintaining a cooperative learning environment, and less on reactive aspects of TBLT such as providing corrective feedback. Results are discussed in terms of their implications for teachers and teacher training programs seeking to implement TBLT as an approach to language teaching.
