Abstract

Problem-solving abilities have an important role in learning, especially in solving math problems, one of which is in circle material. This study aims to describe the mathematics problem solving process of junior high school students in solving circle problems through the process of solving problems in IDEAL. The approach used is a qualitative approach with a descriptive type. The sampling technique used in this research is purposive sampling technique. The results showed that, based on the problem-solving process, each subject had a different problem-solving process. S-1 with the category of completely solving problems fulfills the indicators in solving IDEAL problems. S-2 with the category of correct but not perfect does not yet fulfill the IDEAL problem-solving process. S-2 experienced errors when exploring the strategy and implementing the first problem strategy so that the final result was not in accordance with the objectives of the first problem. S-3 with the category of imperfect does not yet fulfill the IDEAL problem-solving process. S-3 only fulfills one IDEAL problem solving indicators, implementing strategies. However, the problem-solving process carried out by S-3 is not exactly in accordance with the objectives of the first and second problems.

Abstract

Giving assignments as an assessment in online learning during the pandemic needs to be well-considered properly so that students are not frustrated with the piling up tasks but are unable to give educators an idea of ​​students' concepts understanding. This qualitative study aims to describe students’ responses to assignments in the form of journal writing in the Real Analysis course. The research was conducted by asking 109 students who took the Real Analysis class to write journal. At the end of the semester, students were asked to fill out a survei to find out the student's response to the task of writing a journal. Several students were then interviewed to get a more detailed information of the responses given in the survei. The results showed that 94% of the 109 students considered journal writing assignments need to be given in the Real Analysis course. As many as 99% of students agree that the feedback given by the lecturer helps students understand the material. Finally, 94% of students agree that journal-writing assignments are effective for improving understanding in the Real Analysis course. The results of the analysis of journals written by students showed that on average, more than 80% of students wrote notes related to concepts they had previously. It shows a meaningful learning process so that journal-writing assignments can be an alternative to achieve meaningful learning, especially in online learning during a pandemic.

Abstract

Currently, the learning process is still done online. This is a challenge for teachers to continue to apply problem-solving skills in the mathematics learning process. One of the appropriate mathematics materials to measure students' problem-solving abilities is geometry. Geometry material is often an obstacle for students because geometry material is abstract. Therefore, teachers must analyze students' problem-solving skills during the COVID-19 pandemic, especially geometry material. The purpose of this study was to describe students' problem-solving ability in answering geometry questions given by the teacher. This study uses descriptive qualitative research because of the Covid-19 pandemic. The subjects used were 20 students of grade VIII from one of the schools in Pekanbaru. The sampling technique used in this research is purposive sampling technique. The instruments used are test instruments, interviews, and documentation of student answers. Data analysis used was descriptive qualitative method referring to the Polya error indicator. The results of this study indicate that students' problem-solving abilities are still relatively low. This can be seen from some students experiencing difficulties solving the given geometry problems. So that teachers must be able to improve students' problem-solving abilities.
