The document outlines a systematic process for evaluating existing teaching materials based on the needs and requirements of a specific course. It involves identifying requirements across topics like aims, content, skills, methodology, and aids. Then existing materials are analyzed against the same criteria to determine how well they match the identified needs. Results are compared and scored to help select materials that provide the best match overall or in important areas. The evaluation process aims to identify suitable existing materials and avoid duplicating effort, while ensuring a methodical matching of needs with available solutions.
