Pseudo-thinking process in solving logic problem

This study was intended to describe the students' false-pseudo-thinking process in solving a mathematical logic problem. The problem presented was the true value of a statement without using the truth table. The subjects consisting of male and female students. Data collection used the think aloud method. The results indicated that (1) in understanding problem: male subjects were able to understand some components of the problem, women could understand each element of the problem; (2) in planning problemsolving: male subject unaware of the initial concepts needed to solve problem, while female subject aware of it; (3) in implementing the plan: both male and female subjects used incomplete knowledge structures to solve problem; and (4) both subjects did not re-check the answers found. The thinking structure of false-pseudo in solving mathematical logic problem occurred because 1) the lack of initial knowledge that will be used to plan problem-solving, 2) similarities: the habit of completing the previous practice makes the subject consider the many similarities in the problem-solving process, and there is no reflection on the answers given.
