Analysis of Student’s Mathematical Communication Skills in Terms of Self Confidence in Class XII Statistics Material
Full text linkIn the learning process, only a few students were involved in learning, others preferred to remain silent. When given the opportunity to work on questions in front of the class, only those students were brave. In the learning process, students' mathematical communication skills are also seen. Knowledge: When students are given story questions, students are not able to find the information contained in the questions, students have difficulty understanding the information presented in pictures or graphs. This makes students experience difficulty in solving questions. For this reason, this research aims to explain and determine students' mathematical communication abilities (KKM) based on students' self-confidence in class XII statistics material. This research will describe the KKM of students with high, medium and low self-confidence. The research method used in this research is qualitative descriptive research. The research subjects were 9 students of class XII MIPA A SMAN 1 Ngabang. Research subjects were selected based on the results of a self-confidence questionnaire that had been filled out by students. Data collection uses questionnaires to collect data on self-confidence, test questions and interviews to collect data on mathematical communication skills. The data analysis techniques used are data reduction, data presentation and data verification. The results of the research and discussion showed that students with high self-confidence can fulfill the four KKM indicators well. By obtaining KKM scores of 81%, 75% and 69%. Students with moderate self-confidence can fulfill the four KKM indicators quite well. By obtaining KKM scores of 44%, 44% and 38%. Students with low self-confidence are less able to fulfill the four KKM indicators. By obtaining KKM scores of 13%, 6% and 6%.
Students' Thinking Process in Solving Geometry Problems based on Harel Theory on Malay Traditional House Design
Full text linkThe thinking process is a cognitive development that occurs in the minds of students by involving new knowledge and problems that occur related to geometry concepts to solve problems or find solutions to the problems presented. This study aims to study and describe comprehensively the thinking process of students in solving geometry problems based on Harel theory in the design of Malay traditional houses. This research method is qualitative research with a case study design. Furthermore, the data collection used is observation, tests and interviews. Then for data analysis carried out is reflective analysis with data trustworthiness using the triangulation method. Thefindings in the research of students' thinking processes in solving geometry in the design of Malay traditional houses are the core category / central phenomenon built or constructed by three themes which include mental act, ways of thinking and ways of understanding. Ageometric spec on the design components of West Kalimantan Malay traditional houses includes rectangles, triangles, squares, parallelograms, semicircles, isosceles triangles, right triangles, rhombuses, and trapeziums. The findings in this study need to be implemented in mathematics learning design, which relates to students' experiences in everyday life that touch the realm of local cultural arts so that students become more understanding of the geometry concepts explained so that they can dig deeper into mental acts, ways of thinking and ways of understanding in order to foster various student thought processes in Solve mathematics problem
Mathematics Problem Solving Ability In Pontianak Private High School Level Quiziz Game
Full text linkThe ability to solve mathematical problems on Quizzizz illustrates that the data obtained from this research is used as a reference in writing reports. Learning through quizizz can also make students' motivation higher because the games played can be varied using game techniques. To keep up with existing developments, the ability to solve mathematical problems on Quizizz is seen from how high, medium and low ability is. This research describes abilities of Pontianak Private High School students in the context of using the Quizizz application as a learning medium. With a descriptive qualitative approach, this research involved students from a private high school in Pontianak who were given Quizizz as an assessment in mathematics learning. Data was obtained through direct observation, interviews, and giving Quizizz to students. The results of the data obtained were that high problem solving ability was 14.28%, medium ability was 48.57%, and low ability was 37.14%. The research results show that using Quizizz can improve students. Data analysis revealed three categories of problem solving ability, namely high, medium and low, based on the results of working on Quizizz. Likewise, planning problem solving plays a vital role in improving problem solving abilities. Students with high abilities are able to motivate themselves, while students with moderate abilities need a planning and motivation process to achieve high abilities.Applying design in problem solving is also a determining factor. Students with high abilities can implement designs well, requiring collaboration of understanding and ideas. Meanwhile, students with moderate abilities need designs that are strong in ideas. This category is described through the stages of problem solving, including understanding the problem, planning a solution, implementing the design, and checking again. So Quizizz is here to get rid of the threat of students solving mathematical problems

Analysis of Computational Thinking Skills of Students on Exponential Equation Materials through Learning Videos
Full text linkComputational Thinking (CT) is a very important skill for everyone because it is not only for solving problems related to computer science and mathematics, but also for solving various problems in everyday life. The application of computational thinking skills in Indonesia is still constrained which results in low computational thinking skills of students. This study aims to identify the ability of computational thinking in students through learning videos containing problem solving using the stages of computational thinking developed on the material of exponential equations. This study used descriptive qualitative methodology with 34 grade 10 learners in one of the high schools in Palembang as research subjects, focusing on three learners who showed high, medium, and low abilities. The research was conducted in three stages: preparation, implementation, and data analysis. Data were collected through written tests and interviews to measure learners' computational thinking ability. The results were analyzed through three stages, namely: data reduction, data presentation, and conclusion drawing. The results showed that learners showed proficiency in exponential material, especially in terms of pattern recognition and abstraction. However, in decomposition and algorithm skills, learners show a lack of ability in solving problems with a systematic approach and accurate solutions
