In this research, the experimental design pre-post test with a control group is employed. The study was conducted with 81 students in middle schools in Istanbul, Turkey. Assessment tool is used: "Cause-Effect Relationship Scale". Improvements that stem from system dynamics are observed in the tests that measure capability of understanding causal relationships. However, in the boundaries of the research, no significant level of improvements was observed in the perceived understanding of causal relationships. © IDOSI Publications, 2013.eninfo:eu-repo/semantics/closedAccessCausality RelationshipsScience And Technology CourseSystem Dynamics ApproachArticle4564N/A44928
