<![CDATA[This study aims to analyze students’ misconceptions on the topics of momentum and impulse using a multirepresentation-based Four-Tier Diagnostic Test instrument. Conceptual understanding in physics is essential because it forms the basis for students to explain natural phenomena scientifically. However, many studies show that students still experience misconceptions, especially in the concepts of momentum and impulse. This research used a quantitative descriptive method with a sample of 100 tenth-grade students at SMA Negeri 3 Jambi City who had previously studied momentum and impulse. The research instrument was a multirepresentation-based Four-Tier Diagnostic Test consisting of four response levels: conceptual answer, confidence level in the answer, reasoning for the selected answer, and confidence level in the reasoning. Data were analyzed by categorizing students’ responses into five conception categories: Scientific Conception (SC), Misconception (MSC), Lack of Knowledge (LK), False Positive (FP), and False Negative (FN). The results showed that the percentage of Scientific Conception was 39% in macroscopic representation and 28% in symbolic representation, while Misconception reached 30% and 25%, respectively. These results indicate that students understand concepts more easily through real phenomena than symbolic representations. Therefore, the use of the multi-representation-based Four-Tier Diagnostic Test can identify students' misconceptions more accurately.]]>
