State assessment directors and State science supervisors discussed alternative methods for assessing student learning in science at a conference. The conference had two objectives: (1) to increase the knowledge of state science supervisors and assessment directors of recent experience at international, national, and state levels with alternative methods of student assessment in science, such as hands-on exercises; and (2) to inform and assist states in planning alternative methods for state science assessment programs. Presentations and discussions of alternative methods by Senta Raizen, Rodney Doran, Walter McDonald, Joan Baron, Douglas Reynolds, Edward Roeber, and Zack Taylor are provided. A discussion on the issues of validity, role of assessment to "drive" versus "reflect" the curriculum, time requirements, cost, and use for trend data concerning the development and use of alternative methods of assessment in science is included.
