One of the achievements of learning vector calculus is how students can solve problems related to Vector Calculus. However, in its application, students still experience many difficulties when solving problem-solving questions. This research aims to determine the structure of students' thinking when solving problems related to vector material. So that further research can be carried out to overcome these problems. This research method is qualitative. Data was obtained from test results and interviews. Next, the data was analyzed through 3 stages: data condensation, data presentation, and conclusion. In this study, errors made by students were grouped into 3, namely high-level errors, medium-level errors, and low-level errors. At a high level of error, the mistake made by students is that students are not correct in choosing a solution strategy. The problem-solving presented by this group shows errors in Pseudo construction and Mis-logical construction. The errors that occur at a medium error level are misalogical construction. In this case, students have started to use logical strategies but are wrong in applying the concept. Students equate the concepts used with other concepts. Students at the mild error level indicate that errors occur in pseudo-construction. The student's answer is correct, but the student cannot explain the answer correctly. Students make errors in the structure of thinking when solving problems. The lecturers must pay attention to these to consider the right method for learning Vector material. © 2025 Author(s).
