This study employed a correlational study aimed to identify basic cognitive abilities in chemical materials and their relationship to learning styles. The sampling technique used purposive sampling. Data collection techniques were an instrument of cognitive matter, a learning style questionnaire, and an interview. The involved samples were Chemistry Education Department students batch 2017 taking Chemistry School Course. Data analysis techniques were Rasch model and SPSS. The results showed that the value of person reliability of 0.00 and item reliability of 0.89. In addition, the value of INFIT MNSQ and OUTFIT MNSQ for each student on the average value of 0.97 and 0.93. Then, for INFIT ZSTD and OUTFIT ZSTD were 0.1 and 0.2. These can be concluded that the consistency of their answers is in the weak aspect, whereas the quality of items is in the good aspect, and they can answer many questions correctly as can be seen through scalogram. Another thing is that some students do not meet the criteria of person fit data, as well as on item fit data, and their inconsistent pattern of answers. As much as 62% of students were on the Visual learning style, 63% of them were on Audio learning style, and 59% of the students were on Kinesthetic learning style. Then, their basic cognitive abilities have no correlation. Even though the learning styles do not improve their academic ability, this identification helps in detecting the students' tendency to learn even there is a strong correlation between the learning style one another.
