This study compares two hypnoteaching models used to teach students mathematics. Due to the increase in the use of these models, further vigorous studies are needed to verify their effects. This is a quasi-experiment research conducted to compare the use of the hypnoteaching model using three classes of students. The first, second, and third classes of 15, 13, and 15 students were randomly taught with the Erickson Hypnoteaching Model (Erickson-HM), Elman Hypnoteaching Model (Elman-HM), and conventional non-hypnoteaching model (CM), respectively. The results showed that students in the Erickson-HM group outperformed others, while those in the ElmanHM group performed better than their peers in the CM group. In addition, students in both hypnoteaching groups had higher motivation in learning than those in the CM group. Therefore, discussions and suggestions on hypnoteaching of math were proposed.
