investigating is to survey structural relation of critical thinking based on the, learning methods, and metacognition intercession.

The perpose of this study was to investigate the structural relationship ( compilation modeling) of critical thinking based on the learning style metacognition mediation among students of the Army Medical University. This study was a quantitative and correlational study. Participants of the study included 300 students from Army Medical University stratified random sampling was done. The instruments for . Collecteing data for this study were Kolb's Learning Style Questionnaire (1985),wells meta- cognition Questionnaire(1997), Rickets's Critical Thinking Questionnaire (2003), data analysis done with Amos software with path analysis method the findings showed that ther is significant relationship between learning style of reflective learning active, abstract testing and metacognitive with mediation critical thinking, at the P≤0.1 level. However objective learning style indirectly with mediation critical thinking. There is a direct and meaningful relationship between the learning style .there is no meaningful relationship between of reflective learning active and abstract testing with critical thinking at P≤0.01 levels. But there is no direct relationship between objective learning style and critical thinking. also there is a significant relationship between learning style of reflective learning active, objective, and abstract, directly related to metacognition, at P≤0.01.
