Probabilistic Thinking of Senior High School Students with Low Mathematical Abilities in Solving Probability Tasks

Probabilistic thinking of each individual in solving probability tasks is different. Different mathematics ability also causes different process of student thinking probabilistic. This study aimed at describing the profile of probabilistic thinking of high school students with low mathematics abilities in solving probability tasks. This qualitative research was a case study. The subject in this study was a female student in 11^th grade of science that had learned probability and had low mathematics ability selected based on mathematics ability test. The subject was given Problem Solving Tasks then she was interviewed based on her written answers. Data credibility used time triangulation. The results showed that in solving probability tasks, subject used personal experiences found in her own family and extended family. The subject used intuitive strategy that tended to use heuristic thinking patterns by performing attribute substitution process. In this case, subject gave a non-statistical response. The results of this study can complement the existing theories and become input for teachers to use approaches and strategies in learning that can accommodate the probabilistic ways of thinking of high school students in solving probability tasks.
