This issue of the Biological Sciences Curriculum Study (BSCS) newsletter is mainly devoted to reports of the international adaptation of the BSCS materials. The BSCS director provides an overview of the international cooperation program, and a member from most of the adaptation teams contributes a short report on the progress of adaptations in his country. Reports on projects in Argentina, Brazil, Chile, Colombia, Denmark, Great Britain, Hong Kong, Indonesia, Israel, Italy, Japan, Korea, Malaysia, Mexico, New Zealand, Peru, the Philippines, Portugal, Puerto Rico, Sweden, Venezuela, Vietnam, and Yugoslavia are included. Other international adaptations in countries which did not submit an account are mentioned. The use of versions originally developed for Latin American countries having North American schools with Spanish speaking students is noted. A list of area consultants in each of the United States is appended for the information of personnel planning inservice institutes. (AL)
