We are developing and assessing Quantum Interactive Learning Tutorials (QuILT) for the advanced undergraduate courses. The following features of these materials make them particularly suited for the challenging task of teaching quantum physics:
- They are based upon research in physics education and pay particular attention to cognitive issues.
- They employ visualization tools to help students build physical intuition about quantum processes.
- They consistently keep students actively engaged in the learning process by asking them to predict what should happen in a particular situation and then providing appropriate feedback.
- They attempt to bridge the gap between the abstract quantitative formalism of quantum mechanics and the qualitative understanding necessary to explain and predict diverse physical phenomena without dumbing down the content.
- They are based on systematic investigations of difficulties students have in learning various concepts in quantum physics.
- The QuILTs can be used in class by the instructors once or twice a week as supplements to lectures or outside of the class as homework or as self-study tool by students.
- The QuILTs consist of self-sufficient modular units that can be used in any order that is convenient.
Some QuILT modules expose students to contemporary and exciting topics such as quantum teleportation that can be taught using simple two-level systems.
The tutorial development goes through a cyclical iterative process that includes research on student difficulties in learning a particular physics concept, followed by the development, evaluation and refinement of the material. We are currently beta-testing several QuILT modules. If you are teaching quantum mechanics and would like to implement the modules in your class and provide us feedback, please send an email to firstname.lastname@example.org
A majority of the computer-based visualization tools for this project are being developed by M. Belloni and W. Christian at Davidson College under the Open Source Physics (OSP) Project.
The concept tests for quantum mechanics can be downloaded below. The order of the concept tests is based on the textbook of Griffiths. However, the concept tests are compatible with other QM textbooks.
Here are the QuILTs we have developed so far. The simulation programs (.jar file) may need Java Runtime Environment (JRE) to run. (Click here to download the JRE) Some of the QuILTs have already be packaged in one jar file. For these packaged QuILTs, you can directly click the link in the jar file to release the documents (pdf files) such as pre/post tests or tutorials. Note that the pdf files will be released to the same folder as the jar file. So if you burn the jar file on a CD, the documents may not show up after you click the links in the file since there is no free space in the CD folder.
The readme file (PDF) contains the instructions on using QuILTs and the related references
Quantum Mechanics Survey
The Quantum Mechanics Survey is a 31-item multiple-choice test used to explore the conceptual difficulties that undergradutate and graduate students have with quantum mechanics.
Quantum Mechanics Formalism and Postulates Survey (QMFPS)
The Quantum Mechanics Formalism and Postulates Survey is a 34-item multiple-choice test used to explore student difficulties with the formalism and postulates of quantum mechanics.
The Reflective Homework is a set of open-ended questions helps students to review the contents learned in the undergraduate quantum mechanics course.
clicker question sequences (CQS)
These are folders for several of our clicker question sequences (CQS) for quantum mechanics. Many of these CQSs were developed taking instructional inspiration from research done in the development of analogous quantum interactive learning tutorials (QuILTs), and therefore have with them the same validated pre/posttest and solutions. Others of these CQSs were developed in the spirit of such instruction, but required quizzes to be written separately.
