Every year in my Psychology class, I assign students to create a guide for other teens and/or their parents. Most of the time these guides are aimed at younger students and most of the time my students choose a topic for their guide where they have had real-life experience.
This project is always one of the favorites because students really like to help other people who could be struggling with some of the same issues they had in their adolescence.
This project has a list of topics students could do their guide on and a scoring guide. The preview also includes a finished version of a guide created by one of my students. You can use it to show your students the type of work you would like to see.
