As a pilot effort to match research and development information and products with textual materials being used by schools in the northwest region of the United States, this catalog focuses on materials for writing instruction at grades six through nine. The first section lists products and materials in alphabetical arrangement by title. For each product, information is given on target audience, developing agency, and publisher. A brief description is included and the dissemination source for the product is specified. An asterisk by a title indicates that staff development, a primary factor in improving writing instruction, is a major component of that product. The second section describes the process for matching the research and development products described in the catalog with adopted textual materials and displays the results of application of the process to selected texts. Appendixes include a description of the textbook selection practices of the states of Alaska, Hawaii, Idaho, Montana, Oregon, and Washington and a list of information sources. (HOD)
