Abstract

Students need to engage in analytical and logical thought processes, as well as the construction of mathematical knowledge and ideas, to solve problems. What these students are doing is an example of intuitive cognition. From what we can tell, many students, especially those taking Integral Calculus, do not fully use their mental capacities when attempting to solve issues. This research aimed to identify the extent to which intuition is used to solve problems encountered in the study of Integral Calculus. The method of this research was a descriptive qualitative method. A total of 43 participants from the FMIPA UNIMUS Mathematics Education Study Program participated in the study. The study's findings were that the problems persisted regardless of whether the children were high, middle, or poor achievers. The instruments used in this study are the evaluation questions, the intuition surveys, and the interviewing procedures for both the problem solver and the intuitive. They used evaluation tests, observations, and in-depth interviews to triangulate their results. Data analysis entails three stages: data reduction, display, and verification. Affirmatory intuition was most common among students with high problem-solving abilities. In contrast, those with average skills utilized a mix of Affirmatory and Anticipatory intuition. On the other hand, students with limited talents relied on Anticipatory intuition rather than actual intuition. The findings suggest that when presented with a problem, pupils' first instincts are not universal. It indicates that further investigation would develop pupils' innate ability to solve problems creatively.

Abstract. This study aims to determine students' mathematical thinking skills on numeracy problems. The research method used is the descriptive qualitative method, with the subjects in this study being class VIII G students, totaling 20 students with even absent numbers. The instrument used in data collection used a numeracy test instrument using indicators of mathematical thinking ability from Stacey and interviews. Data analysis techniques used include data reduction, data presentation, and conclusion. The results showed the results of the analysis of the percentage of overall indicators, and the analysis of per indicator for each question of mathematical thinking ability 20 students with even-numbered absences in class VIII G was in the medium category, with an overall average of 33%.

Abstract

Technological progress is becoming more advanced and sophisticated, which has both beneficial and bad effects on child development. Children are more interested in modern technology than conventional things, which causes them to develop apathetic and individualistic dispositions. Traditional games are games that are passed down from generation to generation, highlight noble values, cultural values, and character values, and are good for children's development. The purpose of this study was to identify the cognitive elements, character values, and ethnomathematics components of the game of congklak played by children of the Losarang Dayak tribe in relation to learning mathematics. Thus, the congklak game is increasingly popular and is often used in elementary schools to teach mathematics in Indramayu district. This study used an ethnographic design, field notes, conducted in-depth interviews, and made observations to collect data for research. While ethnomodeling is used to represent ideas and mathematical practices of the Losarang Dayak community through ethical, emic, and dialectical approaches in school mathematics, ethno-mathematics as a type of research seeks to uncover the universally significant features of mathematical activity. The congklak game played by Losarang Dayak children has ethnomathematics elements, character values, and cognitive aspects, according to research findings. Playing congklak helps children of the Losarang Dayak Tribe develop social skills, perseverance, thoroughness, and honesty. Besides that, it also increases sportsmanship, develops analytical skills, fosters creativity in children, trains self-development, and sharpens emotional skills. The cognitive skills needed in congklak games include the ability to count, add numbers, develop strategies, improve memory, foster creativity, solve problems, and understand comparisons of many and few.
