The document discusses different definitions of teaching. It examines operational definitions that define teaching as imparting knowledge or skill but notes these terms are ambiguous. Descriptive definitions include teaching as success, an intentional activity, and a normative activity. The document also discusses a scientific definition of teaching as activities shown to be effective in inducing learning but notes there is little research agreement. A working definition proposed is undertaking ethical tasks intended to induce learning. While a relationship between good teaching and learning exists, the document argues the connection is unclear and many factors beyond a teacher's control influence whether students learn.
