Abstract

This article discusses the problem-solving abilities of students in the flat-sided geometry material in the odd semester of the 2020/2021 school year. This research was conducted at SMP Negeri 2 Gorontalo involving 35 students of class IX as research subjects, who were selected using purposive sampling data collection techniques. Data collection was carried out using tests in the form of story questions to measure problem-solving abilities and interviews to strengthen and add the required information. Indicators used to measure problem-solving abilities include: 1) understanding the problem, 2) plan a solution, 3) solve the problem, 4) recheck the results obtained. The results showed that the average achievement of students' ability levels in solving contextual questions in class IX of SMP Negeri 2 Gorontalo was still in the low category, namely 53.51% although there were some students who got high scores. This is shown by the achievement of the indicator of understanding the problem with a percentage of 44.86%, the indicator of planning for completion getting a percentage of 61.14%, the indicator of solving the problem getting a percentage of 63.86% and the indicator re-checking the results obtained getting a percentage of 43.62%.

Abstract

The COVID-19 pandemic has had an impact on the learning process in schools. For this reason, researchers observed learning at SMA Negeri 1 Gorontalo, it was found that students were still not optimal in solving mathematical problems, especially in formulating steps to solve problems. This research aims to improve students' problem-solving abilities by using GeoGebra on three-dimensional material. The research was carried out at SMA Negeri 1 Gorontalo in class XII IPA 5 from September to October of the 2022/2023 academic year with research subjects totaling 30 students. The research is Classroom Action Research (CAR) using the Kemmis and McTaggart model, which involves the stages of planning, action, observation, and reflection. Data was obtained from observation and written tests. Analysis of observation results was obtained by calculating scores for each aspect criterion observed both on the teacher observation sheet and the student observation sheet, while the written test was analyzed by referring to the minimum completeness criteria. The results of the research show that there is an increase in students' problem-solving abilities in three-dimensional material after taking action using the GeoGebra learning media.

Abstract

This research is survey research using correlation techniques whics aims to determine the correlation between learning styles and cognitive ability on circle material. This research was conducted at grade VIII students of Junior High School SMP Negeri 2 Limboto, Gorontalo regency, 2017/2018 academic year with a sample of 119 students. Data collection techniques were carried out using questionnaires and test. The questionnaire is to obtain learning style data, while the test is to obtain students’ cognitive ability data on circle material. Further, the hypothesis is tested using regression and correlation analysis. Based on the results of data analysis, it is shown that there was a positive correlation between learning styles and cognitive ability on circle material at grade VIII of Junior High School SMP Negeri 2 Limboto, Gorontalo regency. The contribution of learning styles given to students’ cognitive ability on circle material is 9.14%. This value shows the influence given by the learning style of students’ cognitive ability. The result provides information that the lack of selecting and understanding of each student’s learning style influences the level of cognitive abilities, especially on circle material even though the contribution is given is 9.14%.
