A mantra in recent years has been to blame the teachers' unions for many of the problems that beset public education. Americans only need look at Wisconsin, where the governor and lawmakers pushed through legislation curtailing the collective bargaining rights of teachers and other public employees. This special report examines the attempts by a small but growing number of districts and unions to work together to enhance the knowledge and skills of teachers and, in turn, improve the achievement of schoolchildren. Articles in this supplement include: (1) "New Attitudes Shaping Labor-District Relationships" (Stephen Sawchuk); (2) "Contract Yields New Teacher-Evaluation System" (Stephen Sawchuk); (3) "Value-Added Formulas Strain Collaboration" (Sarah D. Sparks); (4) "Union-District Collaboration a Never-Ending Process" (Stephen Sawchuk); (5) "States Urged to Promote Union-District Cooperation" (Sean Cavanagh); and (6) "Memphis Collaboration Is Poised to Bear Fruit" (Christina A.
