Technology can promote collaborative and reflective learning for English language learners in four key ways: 1) by presenting authentic models and student-created models, 2) by supporting self-directed learning outside the classroom, 3) by generating more student output and input during planning, acting, observing and reflecting, and 4) by furthering students' zone of proximal development through review and revision leading to polished work. The document discusses several tools like YouTube, apps, and computer-mediated communication that can be used and provides examples of using role-plays and student-created videos to develop language skills through collaborative projects.
