• Resumen

  • Laboratory projects can teach multiple skills, reinforce lab techniques already mastered, and apply concepts to real-world applications, even in lower division courses. Reiterative projects also provide a vehicle for teaching the process of experimentation. This process includes articulation of the question to be addressed, literature search, thinking and planning, preliminary experimentation for feasibility, detailed experimentation with optimized conditions, evaluation of results, and a final report. Emphasis is placed on the planning phases, and critical thinking is encouraged while the students work. Two lab periods are spent on projects in mid-semester; then one more lab period is used to repeat the project at the end of the semester. The time between is used to discuss the preliminary results and plan improvements. Final results are communicated to classmates and the community-at-large in a poster session.
