This phrase refers to a solution guide for an educational mystery or puzzle, likely designed for classroom use. It provides the correct responses to questions posed within the mystery narrative, revealing the culprit and potentially explaining the motive and method. An example would be a document outlining how evidence within “The Case of Mr. Quad” points to a particular suspect and disproves other possibilities.
Such resources are valuable for educators as they streamline grading and offer a definitive resolution to the learning activity. They can also be beneficial to students who may have struggled with the mystery, providing an opportunity to review the logical progression of the investigation and learn from their mistakes. The use of mysteries in education has a long history, providing an engaging way to develop critical thinking and problem-solving skills. Solution keys ensure these activities can be effectively integrated into lesson plans without undue burden on the instructor.
