Teachers' collaboration and interaction experiences combine great opportunities to exchange knowledge and skills to boost the rigor of lesson plans and impact student learning. This study explores pre-service and in-service teacher collaborations and their interactions in an attempt to create a Scaffolded Reading Lesson SRL plan for grade twelve ESL students. Through the study, several instruments were used based on the previous research. The findings show that teachers' collaboration appeared to be challenging, but also a worthwhile learning experience. The SRL plan is intended to help classroom teachers enhance the reading development in an ESL classroom.
