Abstract

This study aims to analyze students^ mathematical problem-solving abilities in the Covid-19 pandemic era. This research is a qualitative descriptive study. The subjects in analyzing the mathematical understanding ability of high school students were class X students. The study was conducted in the middle of the even semester of the 2020/2021 school year in Bandung. The test instrument in this study was a written test totaling 4 essay questions that were given online via google form because in the era of the Covid-19 pandemic where the teaching and learning process was carried out online (in a network). Each problem represents a step in solving a mathematical problem according to Polya, where the steps for solving the problem are: understanding the problem, developing a strategy or planning a solution, solving the problem according to the plan that has been made, and checking the answer again. All students of class X in a private high school in Bandung are the population in this study with a total sample of 32 students. Based on the research conducted, it was found that the level of students^ mathematical problem-solving ability for each step according to Polya could be achieved well, where: understanding the problem, developing strategies or planning solutions, solving problems according to the plan that had been made, and checking the answers to indicators defines the concept. with a percentage of 90,63 percent, indicators identify and make examples and not examples with a percentage of 78,13 percent, indicators use and utilize and choose certain procedures or operations with a percentage of 70,83 percent, and indicators apply concepts or algorithms to solutions to problems with a percentage of 65,63 percent. However, especially for indicators of applying concepts or algorithms to problem-solving, students have not been able to interpret the problem.
