Abstract
Mathematical problem posing is one of the important things that can help students to know how the developing higher order thinking skill. This study aims to present students^ mathematical problem posing using what-if-not strategy in trigonometry topic. This study was qualitative descriptive research with case study. The data were collected by using a written test, observation and an interview. The test was conducted to measure students^ mathematical problem posing and interview was conducted to determine the factors that influence mathematical problem posing. The research subjects were 10th grade students in Pangkalpinang. The result shows that the students^ mathematical problem posing was better than after using what-if-not strategy. The factors that influence students^ mathematical problem posing are the skill to understand the topic, the skill convergent thinking, the skill divergent thinking, creativity and strategies used by teachers in the learning process.
Keywords: Mathematical critical thinking- problem posing- what-if-not strategy
