Operational and organizational principles are suggested for guiding the establishment of networks to facilitate ongoing interactions between the practitioner and scholar communities in mathematics, science, and technology. These networks would define problems that need attention, carry out research on the problems, and incorporate the results of the research into educational and support programs for the most capable youth. The issue of recruiting talented students impacts on the creation of such networks. Statistical data are presented on graduate school enrollments, scores of science Ph.D.'s on the Scholastic Aptitude Test, and scores on the Graduate Record Examination. The Government-University-Industry Research Roundtable is presented as an example of a scholar-practitioner network, along with other examples such as the Agricultural Research System and Extension Service, Transportation Research Board, Mathematical Sciences Education Board, Ford Foundation Urban Mathematics Collaboratives, and the Yale-New Haven Teachers Institute. The paper concludes with a list of principles for creating scholar/practitioners networks. (JDD)
