 A classroom approach that helps high school seniors analyze engineering disasters as though the students were professional investigators has won the Science Prize for Inquiry-Based Instruction. The curriculum module “Root Cause Analysis: Methodologies and Case Studies” helps students use a systematic approach to analyze engineering failures such as the Titanic disaster and the I-35W bridge collapse in Minneapolis. “When you compare what the students say and write with what the National Transportation Safety Board has in monographs about these disasters, they’re comparable,” says Joe Immel, who teaches the course module at Technology High School in Rohnert Park, CA. “The students’ products are really amazing.”
