Librarians designed a biology tutorial not only to address an assignment, but also to make tutorials more accessible to students with various learning styles. The Science Librarian created the content by using aspects of the Information Literacy Standards for Science and Technology/Engineering, an informal survey of biology faculty, and assignments for the biology labs. The Instructional Design Librarian created multiple modules that engaged users through text, images, audio, and interactive tutorials. The researchers used Universal Design for Learning principles to address multiple learning styles, specifically multiple means of representation, and created a mapping technique for those principles that can be applied to any library tutorial. To assess the effectiveness, students with learning disabilities completed a usability test on the tutorial.ibrarians at East Carolina University (ECU) revised an existing biology LibGuide to incorporate Universal Design for Learning (UDL) elements and transform it into an online tutorial. UDL is an educational framework for creating instruction that allows for inclusion of many different types of learning preferences into the targeted curriculum. The Science Librarian at Joyner Library serves as a liaison to not only science-related fields, but also Project STEPP, an innovative grant-based college retention program for undergraduate students with multiple learning disabilities. This unique combination of duties became the basis for a project to improve a Biology 1051/1101 tutorial with the Instructional Design Librarian at Joyner Library to include UDL.BIOL 1051/1101 is a lab course that counts as a required course for all students entering the science, technology, engineering, and mathematics (STEM) fields and a general education science credit for non-STEM majors. On average, BIOL 1051 has 15-20 sections per semester with 45-50 students per section. BIOL 1101 has 15-17 sections per semester with 45-48 students per section. Both lab classes
