Student difficulties in solving covariational problems

Abstract

This study discusses the difficulties of students in solving covariational problems. The study was conducted on 25 students with 6th semester studies who had completed calculus courses. Students are asked to verbalize what they think while solving problems (aloud think). Next, students are interviewed with an in-depth interview technique to explore the thinking process. The results showed 88% of students had difficulties when given covariational problems. Students are familiar with mathematical problems with counting operations. When given a problem without number information, students experience difficulties
