This publication is one in a series of 12 giving the recommendations that were made for a broad and balanced education program in science for young people. Section one of this guide discusses gender-related issues raised by examining the interests, attitudes, aspirations and behavior that young people bring with them into science classes. Section two considers some of the attitudes and experiences which are present in the environment of young children and help to shape their image of the world. Section three considers daily interactions with students, identifies implications, and includes two checklists for teachers. Section four looks at sex-linked choices currently made by students. Section five looks at the future and the changes required if the goal of equal opportunities in science education are to be realized. An introduction, reading list, and references are provided. (RT)
