• Resumen

  • A multilevel assessment strategy, called the stoplight quiz, has been developed and implemented in analytical chemistry courses. Stoplight quizzes are given in three phases, individual, group, and instructor, with three different ink colors that mimic a traffic light. In the individual phase, students record answers in green ink. This is followed by group work during which students can modify their answers with orange ink. The instructor later marks the work in red ink. Correct work in green receives full credit, correct work in orange earns half credit, and red marks receive no credit. This assessment technique has many positive outcomes including increasing student motivation and student understanding of material. Stoplight quizzes can be used in any chemistry course and applied in other disciplines as well.
