For Alan Aspuru-Guzik's course on Quantum Chemistry, students are assessed on the material through "Concept Tests." The students are expected to read chapters from the text books before class, and then they answer questions about quantum mechanics in class using clickers. The students vote on the answer and re-vote if the correct answer receives less than 80% of the vote. This activity works well for peer instruction, because the students discuss the answers with each other and have to re-think the question if the majority of students get the wrong answer. For quantum chemistry and quantum mechanics, the students often have trouble with the concepts initially so this activity helps them understand and be aware of their weak areas.
Professor Aspuru-Guzik and Hongkun Park use a similar teaching method for Physical Sciences 1 to test concepts from the lectures.
