First, students can use it to find study materials on topics they are interested in. Many of the descriptions are written in "teacher speak"' however, so students may initially need some help from teachers in order to determine the key words to use in their search. With that small adaptation, teachers pay teachers can become a valuable library of study materials for students.
Second, students could also create a teachers pay teachers page. By providing the study materials they have created and found helpful, they could provide a valuable perspective for teachers. Student work may have mistakes, but the experience of designing and publishing study materials, lessons, and guides can be a powerful.
I hope these ideas inspire you to explore the resources on teachers pay teachers. How do you plan to use the site?
