Abstract

Concept image can be interpreted as a concept related to the total picture of the cognitive structure possessed. Each student will have a different concept picture according to the experience gained. This study aims to describe the concept image of students in the exponential function material based on learning experiences during the covid-19 pandemic. The research method used is qualitative with a hermeneutic phenomenological approach. Data collection is done by giving tests and interviews. The participants in this study were 15 students in one of the public high schools in Mataram City who had studied the material on the exponential function. The data analysis used is a data analysis technique developed by [1] namely: 1) Data reduction, 2) Data presentation, and 3) Conclusion drawing. The results showed that students^ concept images were constructed independently based on learning experiences during the covid-19 pandemic so that students still had difficulty answering questions and were less able to connect the concepts they had when applying them in solving problems.
