Do you know the difference between a skill and a strategy?
Skill: end product of practice
Strategy: used to get the skill (process, or transaction)
A similar illustration is instructions vs. instruction, or directions vs. teaching.
If you are looking for techniques on teaching reading comprehension, then I highly recommend the book: When Kids Can't Read. Included are pages and pages of clearly detailed and specific strategies ready for explanation to students.
