... y in the class using PBL model and PBL-Teaching Teachers for both middle and low-level schools. At a medium level, improving the mathematical disposition of students with PBL-Team Teaching methods is better than PBL and conventional models. There is a significant interaction between mathematical disposition abilities based on the schools level and the use of learning models. There is no interaction between mathematical disposition ability and the use of learning model when viewed from Mathematical Preliminary Ability.
