Abstract

This research aims to assess students' mathematical problem-solving abilities regarding arithmetic sequences and series. The research was conducted in one high school of Karawang district, where a total of 35 students were taken from a single class. From the data collected, it was found that 25 students, which accounts for 71.4%, had medium-level mathematical problem-solving abilities, while 5 students, each from the high and low categories, accounted for 14.3% respectively. The researchers selected three students as samples to analyze each indicator of their mathematical problem-solving abilities. The study results indicate that students in the low category have not achieved the indicators of planning and checking again. Students in the medium category have not reached the indicators of checking again, while students in the high category have achieved all the indicators of mathematical problem-solving ability. The average indicator score for all students in the research is 46%, which is still low.

Abstract

The purpose of this study is to ascertain how learning activities affect students' capacity to solve mathematical problems involving quadratic functions. Because of the weight placed on students' capacity to solve mathematical problems, the findings of this study should assist educators in implementing instructional strategies that prioritize learning activities. 81 students served as the sample for this study, which was carried out in one of Karawang City's State Senior High Schools. The quantitative Expost Facto method and strategy were employed in this investigation. Simple random sampling was the method used to acquire the data, and simple linear regression was the method utilized to analyze the data using the normalcy, linearity, and hypothesis tests. With a Sig value of.000, it is evident that learning activities have a significant impact on students' ability to solve mathematical problems. The regression equation is Y = 59.674 + 0.408X, and the influence is 23.3%. The findings also indicate a positive relationship, indicating that students' ability to solve mathematical problems will increase with activity level.
