This experimental study was aimed at investigating the impact of M-Apos Learning model in enchancing student conceptual understanding and learning motivation in Calculus II Course. The population was students of Faculty of Industrial Technology, Jayabaya University, Jakarta; while the sample was two classes of Calculus II Course. One class was assigned as experimental group, where M-APOS learning model was applied; while the other class as control group, which used traditional learning. Prior and after the treatment, test on conceptual understanding and quetionnaire on learning motivation were administered. The results showed that (1) there were differences between the ability of students conseptual understanding through M-APOS learning model and those through conventional learning, (2) there was no difference in learning motivation between the two groups; (3) there was no interaction between prior knowledge on the learning model, and (4) there was correlation between the ability of conseptual understanding and learning motivation.
