This volume explores the application of computer simulation technology to measurement issues in education -- especially as it pertains to problem based learning. Whereas most assessments related to problem solving are based on expensive and time consuming measures (i.e., think-aloud protocols or performance assessments that require extensive human rater scoring), this book relies on computerization of the major portion of the administration, scoring, and reporting of problem-solving assessments. It is appropriate for researchers, instructors and graduate students in educational assessment, educational technology, and educational psychology.
