A really nice sample essay Prezi you can use in your class:
It explains a sample that includes exegesis and evaluation and focuses on the things students seem to miss most: that the introduction should be about the essay (rather than presenting information), that the reader needs some roadmapping (I’ve also heard it called ‘sign-posting’) and that essays are best when reader-centric. I’ve found this sort of focus on the reader helps students understand the perspective and tone they should take in a formal essay.
For those new to Prezi, it’s a dynamic presentation software that uses shifts in perspective and zoom to guide presentations (free to use online, and worth checking out here).
