Although new forms of learning call for new forms of assessment, many faculty struggle to find different ways of testing their students' achievements. This issue introduces readers to both theory and practical examples of innovations in assessment in the college classroom. Examples include authentic testing, testing with multimedia, portfolios, visual synthesis, and performance-based testing, among others. Contributors also argue that student performance on exams can be improved by techniques that can be implemented both before and after the exam to make the students better learners. This is the 100th volume of the Jossey-Bass quarterly report series New Directions for Teaching and Learning.
