  Posing high-quality problems is a critical skill to be possessed by students
in learning mathematics. However, it is still limited in literature in
answering whether problem posing learning model effective in improving
students' learning achievement and motivation. Therefore, the present study
aims to investigate the effect of problem posing learning model in the topics
of cube and cuboid on students' learning achievement and motivation. This study
employs quasi experimental design with 20 students in experimental group and 24
students in control group. The study found that the problem posing learning
model has insignificant effect on the students' learning achievement but has a
positive and significant effect of the learning model on the students' learning
motivation. Further analysis showed that the learning model also has a
significant and positive effect on every aspect of students learning
motivation, namely students' interests, enthusiasm, diligence, collaboration,
and self-control.
