Abstract

This study aimed to describe students’ performances and explore students’ learning difficulties in solving calculus problems. This study used a qualitative descriptive approach. The subjects of this research were 23 twelfth grader students of SMAN 4 Banda Aceh, while the interview subject was one of students who had made a lot of mistakes while following the tests and communicative. The data were analyzed by displaying data, analyzing, interpreting, and concluding. The result obtained generally students’ performance in solving calculus problems involving understanding, applying, and reasoning included in middle-performing, and low-or-poor-performing. The students were difficult in applying knowledge, understanding, and reasoning in solving calculus problems. Abstrak Penelitian ini bertujuan untuk mendeskripsikan kinerja dan mengekplorasikan kesulitan belajar siswa dalam menyelesaikan masalah terkait kalkulus. Penelitian ini menggunakan metode kualitatif deskriptif. Subjek penelitian adalah siswa kelas XII SMA Negeri 4 Banda Aceh berjumlah 23 siswa, sedangkan subjek wawancara adalah salah satu siswa yang memiliki banyak melakukan kesalahan ketika mengerjakan tes dan komunikatif. Analisis data dilakukan dengan mendisplay data, menganalisis, menginterpretasi, dan menyimpulkan. Hasil analisis diperoleh umumnya kinerja siswa dalam menyelesaikan masalah kalkulus yang melibatkan pemahaman, aplikasi dan penalaran termasuk kategori cukup, kurang baik atau tidak baik. Kesulitan yang dilakukan siswa adalah kesulitan menggunakan pengetahuan, pemahaman, dan penalaran dalam penyelesaian masalah terkait kalkulus.

Abstract

Learning that does not encourage students to learn in building knowledge results in weak mathematical understanding skills. The strategy that is expected to foster mathematical understanding skills is through the APOS-based discovery learning model. The purpose of this study was to determine the increase in mathematical understanding skills after receiving learning using the APOS-based discovery learning model, and to determine the interaction between learning and student levels on improving mathematical understanding skills. This study uses a quantitative approach with a pre-test and post-test control group design. The population of this study was grade VIII students of MTsN 1 Aceh Selatan by taking a sample of two classes consisting of an experimental class and a control class. The selection of samples in the study was carried out by random sampling. The instrument used in this study was a mathematical understanding ability test. The data analysis technique in this study used the ANOVA test. Based on the results of the study, it was found that there was a difference in improving students' mathematical understanding skills taught through the application of the APOS-based discovery learning model with conventional learning. Furthermore, the results of this study also identified that there was no interaction between learning and student levels on improving mathematical understanding skills. Therefore, teachers are expected to be able to expand the application of the discovery learning model to other materials without having to look at the background of the students' ability levels because this discovery learning model is suitable for application to all levels of students.
