Analysis of student difficulties in calculus and intervention strategies for problematic students
In engineering-based colleges, calculus is one of the compulsory subjects that is generally given to first-year students. Although this course is important to be mastered by students, some students do not like this lesson and become the cause of their failure to learn the material next. The purpose of this study was to analyze the difficulties students as well as describing the results of the intervention were given to students who have difficulty in learning calculus. This study uses a mixed-method. To see the difficulty of students used instruments in the form of tests given at the end of lectures. The test material is in the form of multiple-choice with 40 items consisting of 12 limit items, 14 Derivative items, and 12 Integral items. The results of tests on 56 students showed that the average tenure of the calculus of 57.3 percent which includes mastery of the Limit on average by 61.5 percent, mastery Derivative average 54 percent and mastery Integral average of 56.5 percent. Furthermore, students who do not reach graduation standards are given a remedial intervention program. Through the remedial program provided, students can achieve the specified graduation standards.
