Student Reasoning Based on Mathematical Ability in Solving HOTS Problems through Differentiated Learning

The mathematical abilities of students with reasoning are closely interrelated. The HOTS-type problem is an effort to improve reasoning ability. The ability of students to solve HOTS questions is still relatively low. Through a differentiated learning model, it is expected to help students in the learning process that suits their needs. The purpose of this study is to describe the application of differentiated learning models and describe the mathematical reasoning ability of students who have low, medium, and high abilities. This type of research is qualitatively descriptive with instruments in the form of observation sheets, questionnaires, test questions and interviews. Data analysis techniques include data reduction, data presentation, and conclusions. Test the validity of data using triangulation techniques. The results of this study show that differentiated learning can improve students' ability to reason. Four indicators of mathematical reasoning are, students' ability to present mathematical problems in the form of written statements, students' ability to make conjectures, students' ability to manipulate mathematics, and students' ability to draw conclusions from problems. Subjects with a high level of reasoning meet two indicators. Whereas subjects with moderate levels of reasoning met only three indicators and subjects with low levels of reasoning met only two indicators. Mathematics teachers should provide learning that is in accordance with the learning style of students and students should also do HOTS type questions more often.

Kemampuan Penalaran Matematis Siswa SMK dalam Memecahkan Masalah Barisan dan Deret Aritmatika

The learners must have reasoning ability. The level of mathematical reasoning ability of students plays an important role in solving mathematical problems, and the application of mathematics to everyday life. This study was conducted with the aim of describing the level of mathematical reasoning of class X SMK Graha Madina Singosari. The method used in this research is descriptive qualitative and the data collection procedure in this research is a written test. Students with low reasoning abilities show that they have not carried out a coherent problem solving process. They did not make any allegations regarding the problem at hand. Students with moderate abilities have carried out procedures coherently but not all questions have been answered correctly. The indicators achieved are making conjectures, carrying out mathematical manipulations and compiling evidence or reasons for the correctness of the solution. Meanwhile, students with high reasoning abilities fulfill all the predetermined indicators so as to reach the correct solution. However, students' mathematical reasoning abilities still need special attention in order to improve because only a third of students have high abilities.

The Influence of Contextual Teaching and Learning (CTL) Learning Approach on Mathematical Reasoning Ability of Class VIII Students of SMP Negeri 3 Pematangsiantar.

Mathematical reasoning ability is one of the learning objectives that are expected to develop optimally in students. But in reality, students' mathematical reasoning abilities cannot always be achieved by students optimally. This is also found in class VIII SMP Negeri 3 Pematangsiantar. One of the factors that causes this to happen is the lack of trained students to use and develop mathematical reasoning skills properly. One of the efforts that can be done to improve students' mathematical reasoning abilities is to apply a contextual teaching and learning approach. The purpose of this study was to determine whether the mathematical reasoning ability of students who used a contextual teaching and learning approach was better than the mathematical reasoning abilities of students who used conventional learning in class VIII of SMP Negeri 3 Pematangsiantar. The type of research used was a quasi-experimental design with a posttest only control design. design. The population in this study were eighth grade students of SMP Negeri 3 Pematangsiantar. Sampling was done by random sampling technique. Class VIII-7 was selected as the experimental class and class VIII-8 as the control class. The research instrument used was a final test sheet in the form of description questions to see students' mathematical reasoning abilities. Based on the analysis of the results of the final test of students' mathematical reasoning abilities, it was concluded that mathematical reasoning abilities by learning using a contextual teaching and learning approach were better than learning using conventional learning, which could be seen at an error rate of 5%. This shows that there is an influence on students' mathematical reasoning abilities. The average test for the experimental class is 82.63 and the control class is 60.59

Kemampuan Penalaran Matematis dalam Menyelesaikan Soal Geometri ditinjau dari Persepsi Siswa

Mathematical reasoning ability is a person's ability to think logically in drawing a conclusion from problem solving in the mathematics learning process. By thinking logically, students can have confidence that the mathematics they learn is reasonable so that it affects the mathematical information and knowledge that students receive. It will also lead to different perceptions of each student in participating in mathematics learning. To determine the ability of mathematical reasoning when viewed from the perception of students, it can be done by giving geometry questions. The purpose of this study was to describe the mathematical reasoning ability of students with positive and negative perceptions in working on geometry problems. This research uses a qualitative approach with exploratory descriptive research. This research was conducted at SMPN 2 Balongbendo with the research subjects of two students of class VIII E, with each of them being a student with positive perceptions and a student with negative perceptions. Data collection techniques used are tests and interviews, while to determine the validity of the data using time triangulation. The results of this study indicate that students with positive perceptions can achieve every indicator of mathematical reasoning ability.
