1. A product approach? A process approach? Which approach do you prefer? Why?
Both approaches are important. I think, their implementation depends on the students’ level of English.
2. In what contexts might one be more preferable than the other? For example, think of teaching children, teaching businesspeople, teaching English for academic purposes, exam preparation etc.
Product approach is required for exam preparation, because most of writing tasks are based on models. In teaching children, businesspeople etc. it’s important to develop both creative thinking and accuracy so both approaches are useful.
