Thanks to Jeff Shirey of Avonworth Middle and High School (Pittsburgh, PA) for joining the NGPF podcast recently. In addition to being an accomplished salsa dancer outside the classroom (his living room has a dance floor), Jeff is a spreadsheet whiz inside the classroom. I became aware of Jeff's work through this news story that focused on his passion for spreadsheets. Jeff shares his insights on favorite projects, how he introduces spreadsheets to his middle schoolers and how he differentiates instruction for his more advanced students. You will certainly walk away with some ideas on how to incorporate spreadsheets in your classroom. Enjoy!
