In this talk, we show how augmented reality (AR) can be used to re-experience reaction mechanisms in chemistry classes using our materials for the teaching of electrophilic aromatic substitution (EAS) as an example. The AR learning environment was tested in five different grade 12 chemistry classes in the state of Baden-Württemberg in Germany in 2022. Results show that the students learned the material well, did not experience high cognitive load, and accepted the AR learning environment, overall. The students’ scores on a knowledge posttest were significantly better than their scores on the corresponding pretest, and their responses to student surveys after the experience indicate a positive attitude toward the use of this AR learning environment to teach the EAS mechanism. During this participatory action research project, two different types of AR (image-tracked and world-tracked) were tested and compared. Students who were taught using the world-tracked AR had higher gain scores on knowledge tests and experienced lower cognitive load than students who were taught using the image-tracked AR.
