Originally written in 1996 and targeted primarily at science classrooms, this revised article explains why critical thinking is important in all classrooms. Teachers of all grades and content areas will find tips to help them help students become better critical thinkers.

In addition to describing factors involved in the critical thinking process, it discusses why each aspect of critical thinking must be addressed for a successful implementation. Also included are examples of activities--and student work generated by those activities--that support the concepts discussed.

There is a short annotated bibliography and links to current reform projects that advocate the ideas, examples, and philosophy described.
