The purpose of this study is to investigate the characteristics and effects of quantum mechanics classes at the University of Florida. The progress and evaluation methods of the class are reviewed and the effects of the class were investigated using the ALC (Academic Learning Compacts) tests of the students who participated in the class. The researcher participated in the class for a semester, observed and recorded the characteristics, analyzed them, and examined the effectiveness of class by comparing the percentage of correct answers in various ALC assessment questions. The study revealed that quantum mechanics class offered quizzes, assignments, midterm and final exams in order to improve students academic achievement. In particular, it was characterized by having 4 hours of office hours while the class time was 3 hours per week. The evaluation was to memorize formulas and evaluate concepts and computational ability. The results of the ALC tests, showed that the correct answer rate was higher for the simple memorization problems, and lower for the complicated computation. Also, the questions that require a higher level of conceptual understanding, exhibited the lower the percentage of correct answers. Therefore, it can be seen that there is a need to guide students to become familiar with numerical calculations with sufficient conceptual understanding. However, the overall correctness rate was 71.9%, and the students who participated in the quantum mechanics class had a very high academic achievement.
