In 1979, North European researchers met informally to discuss issues regarding women in science. In addition to discovering that the issues raised crossed national boundaries and cultural differences, they found that numerous efforts were underway to address their concerns. What started as an informal meeting has evolved today into an international effort that enfolds a conference (GASAT-Girls and Science and Technology). The fourth GASAT conference hosted by the University of Michigan focused on the attraction, retention, and achievement of girls and women in scientific and technological courses and careers. Papers presented in "Contributions" volumes I through III are as follows: (1) "The Monopoly of Classroom Discussion by Boys as a Misleading Measure of Superiority in Science"; (2) "Analogies Promote Learning in Science"; (3) "Teachers' Differential Treatment of Girls in Technological Education--A Celebration of Diversity?; (4) "Are the Girls the Problem? Gender and Computer-Science in the Danish Secondary School System; (5) "Does That Train-Set Matter? Scientific Hobbies and Science Achievement and Choice; (6) "Through the Looking Glass of a Swedish Science Teacher"; (7) "Why are Many Girls Inhibited from Learning Scientific Concepts in Physics? (8) "Girls' Concept of and Attitude toward Technology. The International Patt-Research"; (9) "Females and Physical Science: Is Tinkering an Issue?; (10) "Women's Access to Scientific and Technological Activities in Mali"; (11) "What do Children Think? A View of Science and Scientists"; (12) "Rational Girls and Girls' Rationalities"; (13) "Research Work of Men and Women in Science and Technology"; (14) "Israeli High School Boys and Girls Achievement and Attitudes toward Science"; (15) "The Effect of Same-Sex Role Models on Perceptions of Performance in Science Courses"; (16) "Some Proposals for Integration of Affective and Cognitive Aspects in Physics Education"; (17) "More Girls to Technical Jobs-An Action Plan"; (18) "Psychological Type and Science Career"; (19) "Labour Market Division in Sweden and Its Effect on Attitudes and Education"; (20) "Is There a Place for Women in Biosciences?"; (21) "An Evaluation of Efforts Made in Nigeria To Increase the Participation of Girls and Women in Science and Technology"; (22) "Desexing Computing"; (23) "A Bibliometric Study of the Wisest Women in Pure and Applied Science Bibliography"; (24) "Guidelines for Sex Equity in Textbooks"; (25) Evaluation of a Project Designed To Encourage Girls To Take Up Technical Options in Rural Schools"; (26) "Chinese Women Rise with Force and Spirit in Science and Education"; (27) "The Half Sky--Woman Scientists in our Institute"; "'Radical Feminist Analysis' and GASAT: Some Possible Conflicts?"; and (28) eight articles on intervention efforts. Volume IV, a record of the "Proceedings" that was prepared and distributed after the conference, contains welcoming remarks, theme presentations, and reports of workshops and special interest sessions. Topics highlighted in volume IV are: (1) intervention, i.e. the linking of research and practice, the importance of working at many different levels in many different ways, making use of networks/friendship groups, and the question of co-ed or gender segregated education; (2) GASAT volunteer workshops and special sessions; (3) Gender and Science, including the Squibb International Seminar; and (4) the recruitment of women into science and engineering, including one article by Ina Wagner.
