The Southwest Evaluation and Research Division conducted a survey of 165 purchasers of bilingual instructional materials produced by SEDL to determine which information channels predominate in the curriculum adoption-decision process. The findings of this survey may be useful in the selection of the most efficient ways to communicate information to educators about new instructional products and practices. A survey form was distributed which asked the purchasers to indicate the following: (1) how they first became aware of the SEDL bilingual instructional materials; (2) other sources by which they obtained information; (3) what single information source was most influential; (4) the degree of their personal involvement in this decision; (5) others within their school district or agency who participated in the decision making; (6) availability for further survey information-gathering assistance; (7) current use of the purchased SEDL materials in the classroom; (8) general comments regarding the purchase of the materials. Results and discussion with respect to each of the eight issues are reviewed in turn. The major conclusions were: (1) adopters most often obtain initial information about new instructional products from personal information sources; (2) few purchasers based their adoption-decision on the single initial product information source; (3) the most influential factors were observation of the products in use and personal communication with SEDL personnel; and (4) decisions are most often group decisions.
