Abstract

The ability of representation is part of the five basic standards in learning mathematics. This ability needs to be possessed by students well. Analyzing and describing the representational abilities of junior high school students in solving mathematics based on Higher Order Thinking Skills is the aim of this study. This type of research is descriptive qualitative research. The subject of this study found 4 students taken from 26 students of class IX A SMP Negeri in Temanggung Regency who have high mathematical abilities. The data collection technique of this research used tests, interviews, and documentation. The validity of the data using data triangulation. The data analysis technique used is data reduction, data presentation, and conclusion drawing. The results of the analysis and research descriptions show that students' representational abilities in solving HOTS-based math problems are different. The verbal representation category of S2 and S3 subjects can use verbal representations well and has concluded that S1 has not yet completed the steps, and S4 has not been able to write down the steps on verbal representation. The ability of symbolic representation of subjects S1, S2, S3 still has errors in writing equations but does not affect the results, S4 already assumes equations and expressions correctly. The visual representation categories S1, S2 and S4 have not been able to draw geometric shapes completely, while S3 is wrong in writing symbols on the picture.

Abstract

The problem-solving ability between reflective and impulsive subjects from several studies shows that reflective subjects are always superior than impulsive subjects. The purpose of this study was to identificate and to describe students' problem-solving abilities with impulsive cognitive style in solving superitem test problems and their characteristics. This research is a qualitative descriptive study. The data collection techniques used were the MFFT test, the superitem test, and interviews. Based on the results of the superitem test, it shows that the two impulsive subjects have differences in achieving the level of problem-solving ability thinking. Impulsive-01 subjects can reach all thinking levels based on SOLO taxonomy while impulsive-02 subjects can only solve problems at the unistructural level. Although the research shows that the impulsive-01 subject has the characteristics of being fast, less accurate, less thorough, and seeming rushed in solving problems, the subject can finish up to the extended abstract level. The impulsive-02 is able to connect by making assumptions in solving the problem, it's just that the inability to solve this problem due to not understand the problem.

Abstract

A procept is a combination of mental objects consisting of processes, concepts resulting from these processes, and symbols used to represent either concepts or processes. This study aims to describe the procept profile of the gradient concept and the equation of a straight line for the students of SMPN 1 Sooko Mojokerto. This type of research is descriptive qualitative exploratory. Determining the research subjects was carried out by giving a mathematical ability test to 42 prospective subjects, to obtain 5 students with high mathematics abilities, 22 students, and 15 low students, then from each category one research subject was taken. Data was collected using task-based interviews and analyzed by qualitative data analysis techniques through data reduction, data presentation, and conclusion drawing. The results showed that there were differences in the procept profile of the gradient and straight-line equations between students with high, medium, and low abilities. The procept profiles of students with high math abilities meet all categories, students with moderate math abilities meet most of the categories, and students with low math abilities meet the small categories of gradient and straight-line equations.

Abstract

Problem-solving ability is one of the essential skills for students in learning mathematics. This ability can be developed through teaching and learning activities using student worksheet-based cooperative model. However, these student worksheets are still rarely found in teaching and learning activities in the classroom, so this research aims to develop student worksheets based on cooperative learning models used to develop students' problem-solving abilities. The study used development research methods with ADDIE procedures, namely analysis, design, development, implementation, and evaluation. The test of the developedstudent worksheet was carried out at SMP Negeri 1 Merauke, using valid, practical, and effective categories. It is collecting data through interviews, observations, questionnaires, and tests. Data analysis was carried out by data reduction, presentation, and conclusion. This research produces student worksheets based on cooperative learning models to improve students' problem-solving abilities. The results of this study contribute to enriching teaching materials in the form of student worksheets for educators which can improve problem-solving skills.

Abstract

Critical thinking ability is an essential component of the four skills needed in the 21st century. However, this ability is still challenging to achieve well by students because of the lack of communication and cooperation during learning mathematics. Therefore, this experimental study with a posttest-only control design was conducted to determine the effect of using the jigsaw cooperative learning model on students' mathematical critical thinking skills. This study involved 62 students consisting of 31 students for the experimental class and 31 students for the control class. Data were analyzed using parametric statistics, namely t-test. The calculation of effect sizes is carried out to determine how much influence the Jigsaw cooperative model has on critical thinking skills using the Hedges'g equation. The analysis results concluded that the critical thinking skills of students who were taught using the jigsaw cooperative learning model were better than those taught using the direct learning model, at a significance level of 0.05. Further analysis obtained an effect size of 0.64, indicating that jigsaw cooperative learning has a moderate effect on students' critical thinking skills. These results provide helpful information for educators and researchers to consider mediators that might mediate the implementation of the learning method in the future.

Abstract

Major changes in education caused by the Covid-19 Pandemic led to a decrease in students' thinking skills. Therefore, it is very important to analyze how the level of thinking ability of students in this era. The purpose of this study was to analyze students' higher order mathematical thinking skills in the era of Covid-19 Pandemic by using three stages of metaphorical thinking. This research was conducted in the even semester. The subjects in this study were 11 students of class IIB Mathematics Education Study Program, Universitas Mahasaraswati Denpasar. This research uses descriptive analysis techniques. Data collection was carried out through tests, interviews, observation, and documentation. The results showed that the students' high-order mathematical thinking skills were very low where only 20% of students answered correctly at the grounding metaphors stage, 25% at the linking metaphors stage, and only 25% at the redefinitional metaphors stage. In general, this phenomenon occurs due to the reduced opportunities for students to interact and discuss during online learning in the Pandemic era which also results in a lack of opportunities for students to exchange understanding and knowledge. Students also cannot understand problems in depth and relate concepts to everyday life.
