Educational researchers have the potential to create learning innovations, but there is a forgotten basic idea to improve basic skills through the integration of learning models with the evaluation process. Scientific reasoning is a necessary skill to support student competence in the 21st century. This research aims to analyze the effectiveness of Evidence-Based Reasoning using three ties tests to improve scientific reasoning patterns on the concept of heat conduction. One hundred senior high school students in eastern Java participated in this study. Instruments used in the form of a scientific reasoning sheet from three bonding tests, learning scenarios, worksheets, student questionnaire responses, and teacher interviews. Data were analyzed by paired pair t-test, n-gain, item test sensitivity and Guttman scale. The results show that Evidence-Based Reasoning uses three ties test in improving scientific reasoning. Besides, the n-gain value between pre-test and post-test can be categorized as moderate for five sub-patterns of scientific reasoning on the concept of heat conduction. The implication of this research is the integration of Evidence-Based Reasoning using three ties test can be an alternative to learning to increase scientific reasoning.
