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.
