Abstract

Changes in the learning process during the pandemic affected student learning outcomes. As many as 68% of students score below 75 in computational mathematics courses. These results are not comparable to learning outcomes when learning takes place offline. The results of the interviews show that students have difficulty understanding the material when learning is done online. For this reason, a qualitative descriptive study was carried out which aimed to analyze and describe students' conceptual understanding abilities in solving matrix problems using the APOS stages. The research subjects were 3 students of the informatics engineering study program who had taken computational mathematics courses and received matrix material, were in the category of students with low, medium, and high conceptual understanding, and were able to communicate their thoughts orally and in writing. Data collection techniques were carried out through written tests, interviews, and observations. The results showed that students with low conceptual understanding were able to solve matrix problems up to the object stage and made calculation mistakes. Students with a moderate understanding of concepts can solve matrix problems up to the schematic stage but are not careful in doing calculations. Meanwhile, students with high conceptual understanding can solve matrix questions up to the schematic stage, determine the correct answer, make conclusions, and reflect on the problem-solving obtained.

Abstract

This study was motivated by the observation that students who understand formal mathematics do not necessarily understand non-formal mathematics in society. This shows that mathematics learning in schools has not fully involved the things around students and tends to only train students' ability to answer questions. The purpose of this study is to describe the way pottery crafters construct curved-sided spaces and reveal the concept of curved-sided spaces found in pottery making in Banyumulek Village. This type of research is descriptive qualitative research. The subjects in this study were two pottery artisans who were selected using purposive sampling technique. The research subjects were chosen based on certain considerations, namely the subject is a practitioner or expert in making pottery. The data collection techniques used were interviews, observation, and documentation. The results showed that the way pottery craftsmen construct the curved side space in pottery making consists of 4 processes, namely, making tombong (base), bebentet (curved side), belong (neck or connecting curve), and making biwir (mouth or lid) pottery. In addition, there is a concept of curved-sided space in pottery making in Banyumulek Village, namely the concept of partial tubes, cones, spheres, and the concept of whole tubes.
