Student mathematics understanding through blended learning approach

This study aims to describe students' understanding of the concept of calculus by using a blended learning approach, namely online learning, face-to-face learning, and individualized learning. The subject are students of mathematics education STKIP PGRI Sumenep who has taken calculus course I representative of three categories, namely the category of students with high, medium, and low levels of ability. The data collection technique used a test in the form of five essay questions on indeterminate integral material, interviews to explore student responses using unstructured interview guidelines, and observation to determine student activity in the process of learning activities in calculus courses. The data analysis technique consists of three stages, namely data reduction, data presentation and drawing conclusions. The results show that students are only able to re-state concepts that have been studied before, but students have not been able to provide examples and non-examples as a form of understanding integral concepts and students in relating concepts are still not appropriate and in accordance with the procedure for solving integral problems.
