ABSTRACT
This research aimed to know and to analyze the direct and indirect effects of three multiple intelligences (spatial, verbal, mathematical-logic intelligences) towards students’ mathematical problem solving ability. The subjects were 280 of 9th grade students of SMP Negeri 37 Surabaya. The data were collected by mathematical logic intelligence, problem solving ability, and psychological tests. The psychological test was used to measure psychological constructs of spatial and verbal intelligences. The data analysis used inferential statistics, path analysis. The results showed that: (1) the mathematical logic intelligence was the first determinant factor in the students’ ability in mathematical problem solving (42.7%), and the second was the verbal intelligence (29.2%); (2) the verbal and mathematical logic intelligences had a direct effect to the ability of mathematical problem solving, simultaneously. The spatial intelligence affected indirectly the ability of mathematical problem solving. Individually or simultaneously, it appears that verbal and mathematical logic intelligences had a direct effect to the ability of mathematical problem solving. It implies that mathematics teachers of SMP/MTS should give more opportunities and stimulus of mathematical logic problems and verbal abilities to their students.
