The document discusses peer-led labs as a strategy for scaling hands-on lab experiences to serve large numbers of freshmen. Peer-led labs involve small groups of students (3-4) relying on each other to complete simple lab assignments with inexpensive materials and homemade test apparatus. This develops leadership, communication skills, and allows labs to be incorporated early in the curriculum. Benefits include being inexpensive, scalable to large class sizes, emphasizing quantitative communication skills, and assessing measurement accuracy without expensive equipment. An example course piloting this approach is described.
