Mathematical problem-solving abilities need to be owned by prospective mathematics teachers so that they can teach it to their students later. Integral Calculus course is a course that students need to understand the next course, as well as a course that is closely related to school mathematics. This study aims to look at the significance difference in students problem-solving ability related to video learning implementation. The research design used was a nonequivalent control group design with the subject of 71 mathematics education students from two universities in Indonesia. The instrument used was a calculus prior knowledge test and mathematical problem-solving test, each of which consisted of 3 questions. Based on the statistical test, it was found that the mathematical problem-solving abilities of the two research groups differed significantly. The subject group who used the instructional video had better problem-solving abilities than the subject group whose learning used virtual face-to-face

Student achievement in the national science olympiad in mathematics needs to be improved. One way that can be done is to describe the types of student errors in solving math OSN problems. And the learning styles of students. The research subjects were representative students from Ambon Catholic Junior High School for the Mathematics OSN at the district/city level, totaling one person. Data collection techniques were carried out by giving tests in the form of descriptions, interviews, and learning style questionnaires. The results showed that students made errors based on Newman's analysis, namely, reading errors, understanding questions, and transforming errors once each, processing skills errors and writing errors in the final answer 4. The results of the learning style questionnaire, students have a visual learning style. Some recommendations based on the results of this study are teachers need to provide assistance to students by paying attention to student learning styles.
