This volume, part two of "The Hidden Curriculum," is premised on the belief that testing practices influence educational procedures and learning outcomes. Graduate level science educators shared their assessment techniques in terms of the following categories: (1) exam design; (2) exam format; (3) exam environment; and (4) grading practices. Exemplary innovations in exam practices that assess scientific understanding in new and more appropriate ways are detailed in this book. The chapters are: (1) "Introduction: from Innovation to Change"; (2) "Biology"; (3) "Chemistry"; (4) "Physics"; (5) "Assorted Fields"; and (6) "Commentary." Between chapters 1 and 2 is a section on how to use this book and an index. (DKM)
