Abstract
This study aimed to determine the students problem solving ability in solving the volume of a solid of revolution questions in online Integral Calculus Learning through zoom implementing Student Centered Learning. The research method used in this study was descriptive qualitative method. The subjects were 32 students from class B in the 3rd semester of Mathematics Study Program FKIP UNIB Academic Year 2020/2021. The test was conducted online via Google Classroom on 8th September, 2020. The analysis in Polya stages consisted of: P1) Understanding the Problem- P2) Making a Plan- P3) Carrying out the Plan- and P4) Looking Back. The instruments used to collect datas were midterm test sheets including volume of a solid of revolution questions. The result showed the average score of the students problem solving ability was 1.54 out of 2. The mean value in each stage: P1) = 1.68- P2) = 1.63- P3) = 1.43- and P4) = 1.44. It was concluded that students had good abilities in understanding the problem and planning the solution but they still had difficulties in drawing graphs and calculating the volume.
