If you are hoping to create a library research assignment that goes beyond teaching library-specific skills (e.i. finding a book on the shelf, locating the Research Help Desk, or understanding the Library of Congress classification system), you may want to consider incorporating the Association of College and Research Libraries' (ACRL) Framework for Information Literacy for Higher Education.
In 2015, ACRL introduced the Framework for Information Literacy for Higher Education. The Framework provides educators with a unique set of goals designed to guide information literacy instruction and help identify, articulate, and impart the fundamental necessity of information literacy in today's rapidly changing world.
The Framework places special emphasis on the importance of collaboration and threshold concepts. Additionally, the Framework is contextually broad which makes it well-suited to all disciplines.
