Lawton Chiles GovernorofFlorida, 1991-1998 Social Change, Public Policy and Community Collaborations: Training Human Development Professionalsfor the Twenty-First Century is more than the name of the Third National Applied Developmental Science Conference; it is more than the name of a book prepared from the proceedings of this conference. It describes one of the largest and most complex challenges facing state government, higher education and communities in the coming decade. The answer to this challenge will not be found in a college or program in our higher education institution nor in laws conceived and written in state capitals. The answers to this challenge are to be found at the place where academia, public policy, and communities meet. The problems and issues that are facing our children and families will require that all the players work together to develop community-driven programs, designed and evaluated using current research and staffed by highly trained professionals. It will be critical that academia, policy makers, legislators, and community members work together to ensure that the programs we design work. We must ensure that research is being conducted so that programs that work better are continued and programs that don't are stopped.

The Conference/Workshop of which these are the proceedings was held frcm 28 June to 1 July, 1982 at Williams College, Williamstown, MA. The meeting was funded in its entirety by the Alfred P. Sloan Foundation. The conference program and the list of participants follow this introduction. The purpose of the conference was to discuss the re-structuring of the first two years of college mathematics to provide some balance between the traditional ca1cu1us linear algebra sequence and discrete mathematics. The remainder of this volume contains arguments both for and against such a change and some ideas as to what a new curriculum might look like. A too brief summary of the deliberations at Williams is that, while there were - and are - inevitable differences of opinion on details and nuance, at least the attendees at this conference had no doubt that change in the lower division mathematics curriculum is desirable and is coming."

First published in 1986, the first ICMI study is concerned with the influence of computers and computer science on mathematics and its teaching in the last years of school and at tertiary level. In particular, it explores the way the computer has influenced mathematics itself and the way in which mathematicians work, likely influences on the curriculum of high-school and undergraduate students, and the way in which the computer can be used to improve mathematics teaching and learning. The book comprises a report of the meeting held in Strasbourg in March 1985, plus several papers contributed to that meeting.
