Cognitive style in this research is according to Witkin and Goodenough (1981) in Altun and Cakan (2006) i.e Field Independent (FI) and Field Dependent (FD). Purpose of this research is to know the difference scientific literacy ability of students having Field Independent and Field Dependent cognitive style.

The result of prerequisite test use Kolmogorov-smirnov (α = 0,05) and Levene test (α = 0,05) showed the data normally distributed and homogenous. Result of Independent t-test (α = 0,05) showed p value 0,002<0,05 thereby there is the differences between FI and FD on scientific literacy score and level. Students with FI cognitive style obtain higher score than students with FD cognitive style with mean difference 9,849.
