With increased support for educational standards, teachers need resources to help them engage in standards-based reform. The International Technology Education Association (ITEA) is publishing a series of addenda for this purpose. "Planning Learning: Developing Technology Curricula" offers teachers and other curriculum developers suggestions and tools for planning, developing, and evaluating standards-based technology curricula. Section 1 provides defining characteristics of quality curricula and discusses the relationship of curricula to technology programs. The importance of a planned curriculum is also emphasized. Section 2 explains the differences between standards-based and standards-reflected practices and presents five fundamental planning questions of standards-based curricula. Section 3 provides a multi-step process for developing and revising curricula. Section 4 provides a general overview of the curriculum evaluation process. Section 5 is a call to action that provides direction to teachers and other curriculum developers to gain support for technological literacy from others.
