Why is 学生 marked with に instead of が or を?

In Japanese causative constructions, the person who is made or allowed to perform the action is marked by に. Here, 学生に tells us “to the students” – i.e. the students are the ones the teacher makes or lets write.

What exactly does the causative form 書かせます mean?

書かせます is the polite present of the causative verb 書かせる, which means “to make (someone) write” or “to let (someone) write.” So 先生は学生に…書かせます literally means “The teacher makes/allows the students to write….”

How is the causative form 書かせる built from the dictionary form 書く?

For a Group 1 (五段) verb like 書く, you replace く with かせ and add る:  書く → 書かせる
Then, to make it polite present, replace る with ます:  書かせる → 書かせます

は marks 先生 as the topic (“as for the teacher…”).
を marks 文章 as the direct object of the writing action (“(careful) sentences” that are written).
