To get a clearer understanding, I'd need more context:
* Where did you hear about this strategy? Was it from a teacher, a textbook, or an online resource?
* What is the overall goal of the strategy? Is it for reading comprehension, writing, or something else?
* Could you remember any specific words or parts of the acronym? For example, what does each letter stand for?
Once I have more information, I can help you understand the "STEP PENS" strategy better.
