We believe in the benefits of a student-as-producer approach – students are not only consumers of knowledge but also producers of knowledge. We recruited several students to help with content, assessment, and web design under the supervision and guidance of the project leads. They have had some experience with the course, for example, completing the course as a student, working as a teaching assistant, or a peer tutor for the course. Their perspectives on how a textbook should be designed for students became valuable assets for the project. We appreciate their contributions, without which this project would not be successful. To learn more about these contributors, please take a look at our project team.
