This is a collection of problems on Waves and Oscillations developed to engage students in metacognition, or "thinking about how they think".   The authors have collected context-rich problems that attempt to link a student's qualitative understanding of concepts with specific scenarios.  Topics include masses on springs, pendulums, sound, and waves on a string.  The activities include pictures and diagrams for clarification.  These activities are appropriate for introductory physics students who have completed a course in advanced algebra/trigonometry.

Solutions to the problems are not included.  Teachers may wish to compile their own customized solution sets or may contact the University of Maryland Physics Education Research Group (PERG) for guidance.  A link is provided at the bottom of the resource for communication with the author.
