The American Association of School Librarians "Standards for the 21st Century Learner" (2007) expresses nine fundamental common beliefs. One of these beliefs is that "ethical behavior in the use of information must be taught" (AASL 2007, 1). It is important for library media specialists to understand that teaching ethical behavior is much more than teaching students about plagiarism. In this article, the author focuses on the explanation of ethical principles as well as steps, learning activities, and tools to assist upper elementary through high school library media specialists and content teachers in teaching ethical behavior in the global world of information and the new AASL standards. The learning tasks are focused on problem solving in realistic situations rather than just learning bodies of content. This approach is inspired by the writing of Richard J. Severson in "The Principles of Information Ethics" (Sharp, 1997) and is intended for students who do not have a background in philosophy or ethical theory. Severson's four principles of information ethics, namely (1) respect for intellectual property; (2) respect for privacy; (3) fair representation; and (4) nonmaleficence (or doing no harm), are examined.
