When writing the peer evaluation on Studeo (My Language Profile 11), make use of these questions:

1. Is the text divided into at least 3 paragraphs?
2. Is it a coherent piece of text? = Is it easy to read?
3. Is the structure clear?
4. Are the contents logically built, e.g. not jumping from one aspect to another and back to the first one?
5. Does it have a clear lead-in, an obvious beginning?
6. What is the ending like? Does it have one?
7. How varied vocabulary, structures & phrases are used? Is it idiomatic? Or are sentences & words simple?
8. Is it at least 700 marks long and no longer than 1624 marks?

First, give positive feedback: in which of those aforementioned did your peer succeed?
Next, give constructive feedback: what could have been done differently & how? Remember to be polite. If the composition is in your opinion great and there is nothing to be improved, state that, too. 

You can give your feedback in English or in Finnish.
