Analisis Kemampuan Pemecahan Masalah Matematis Siswa Kelas VIII SMP Dalam Menyelesaikan Soal- Soal Geometri Bangun Ruang

Students' mathematical problem solving ability is one thing that must be considered. This is because when students are given problem solving problems in the form of routine students are able to solve these problems, but if a non-routine problem arises, students will have difficulty. During teaching and learning activities students are able to solve problems when presented with questions of the same type. However, if given a variety of questions, some students have difficulty working on them. This study aims to explore and describe students' mathematical problem solving abilities in solving spatial problems. This study uses a descriptive qualitative approach. The data analysis technique in this study used descriptive analysis techniques. The results of the analysis show that high-ability subjects can understand the problem by writing steps, solving problems, re-examining the results of work very precisely and correctly. Students with moderate abilities can only solve problems without writing what is known and asked. Meanwhile, low-ability students cannot fulfill all aspects of mathematical problem solving.

Implementasi Model Pembelajaran Missouri Mathematics Project dalam Pembelajaran Matematika

The purpose of this study is to examine the Missouri Mathematics Project (MMP) learning model that influences students' mathematical problem solving abilities. This research is a quantitative research using a quasi-experimental approach. The quasi-experimental design used is a posttest-only control group design. The research sample was taken by purposive sampling technique in order to obtain two class groups with different treatments. To obtain data in this study, the instrument of student learning activity sheets and test questions of students' mathematical problem solving abilities was used. The data analysis techniques used consisted of descriptive statistical analysis and inferential statistical analysis. The results of this study reveals that there is significant effect of the MMP learning model on students' mathematical problem solving abilities as indicated by the achievements: (1) student learning activities with the MMP model carried out both by teachers and students are in the very good and good category; (2) the mathematical problem solving ability of students who were treated with the MMP model was 71.60 higher on average compared to students who were treated with the conventional learning model of 35.48; (3) the mathematical problem solving ability of students who were treated with the MMP model was better than students who were treated with the conventional learning model.

Students’ Intuition in Solving Mathematics Problems: The Case of High Mathematics Ability and Gender Differences

Students are required to find their appropriate strategies to solve mathematics problems so that intuition is needed. Male and female students have different intuition on mathematical problem-solving. Thus, gender is influencing how to obtain mathematical knowledge. This descriptive qualitative study aimed to analize the intuition differences of male and female students who have high-level mathematical abilities at secondary school in solving mathematics problems. Data was collected through tests of mathematical problem-solving and interviews then analysed through data reduction, data presentation, and conclusion. This study found that: (1) There are differences in the characteristics of male and female intuition in mathematical problems solving, (2) The intuition of male and female in mathematical problems solving based on Polya's steps is different in re-checking the answers, (3) There are differences in intuition when students solve linear equation system problems. There are differences in intuition between male and female students with high matematical abilities in each material. Students with problem-solving abilities have affirmative intuition to understand problems, anticipatory intuition for problem-solving plans and solutions, and conclusive intuition to re-examine problems.

Correlation Between Learning Motivation and Problem-Solving Ability Based on Gender

The purpose of this study is to determine the relationship between students' motivation to learn and their mathematical problem-solving abilities based on their gender. This study employs a quantitative method with a correlation survey approach to assess students' motivation and mathematical problem-solving abilities. It involves 73 students from Madrasah Tsanawiyah. The data analysis technique used in this study was the product-moment correlation test, which yielded a value of 0.001 for sig.(2-tailed). Means 0.001 0.05, Ha is accepted, and H0 is rejected based on male students. The value of sig. (2-tailed) is 0.003, meaning 0.003 0.05, Ha is accepted, and H0 is rejected based on female students. And the value of sig.(2-tailed) is 0.000, meaning 0.000 0.05 then Ha is accepted, and H0 is rejected. There is a significant positive correlation between learning motivation and mathematical problem-solving with a correlation coefficient value of 0.435 then the level of correlation between variables is a moderate correlation. The coefficient of determination test is (0.435)2 x 100% = 18.92%. This means that only 18.92% of the contribution of the independent variable, namely learning motivation, to the dependent variable, is the student's mathematics learning outcomes and other things influence 81.08%.

Analisis Kemampuan Pemecahan Masalah Matematika ditinjau dari Tipe Kepribadian Siswa Madrasah Tsanawiyah

This study aims to describe the mathematical problem solving abilities in terms of students personality types of grade VIII at MTs Al-Ma’arif NU Qamarul Huda Narmada academic year 2020/2021. This type of research is a qualitative descriptive with a quantitative approach. The sampling technique used saturated sampling and each 2 students were selected to represent each personality types. The data collection technique used are personality type questionnaires, mathematical problem solving ability tests, and interviews. The data analysis techniques used quantitative data analysis and qualitative data analysis that are data reduction, data presentation and conclusions. The result of this study are students with introvert and extrovert personality types are not able to write down the stage of understanding the problem, do the stage of making a plan by writing them into mathematical form, able to write down the problem solving systemtatically but there are some errors, write the conclusion of the answer though it’s not quite right. While students with ambivert personality types are able to do the stage of understanding the problem by writing down even though it’s incomplete, write a plan for solving the problem by directly writing it into mathematical form, are able to write the solution of the problem according to the plan even though there are some missteps, re-examine and write down the conclusion even though there are error in the results.

A STEAM Practice Approach to Integrate Architecture, Culture and History on a Mathematical Problem-Solving Basis

In this paper we propose STEAM practices that would foster mathematics learning through modelling architecture while connecting to culture and history. The architectural modelling process is applied by the teachers as participants of these practices from different countries allowing a broad cultural and historical connection to mathematics education. The modelling is implemented in GeoGebra platform as it is an open-source platform to allow teachers to model on a mathematics basis. The architectural modelling process does not provide participants with steps to follow but rather allows them to explore the architectural models’ components and construct them with various approaches which may foster problem solving techniques. We aim to investigate how different phases of this approach (such as motivation, modeling, and printing process) reflect on opportunities of learning in STEAM education, with a particular lens in mathematical development from open tasks. This paper will show two use cases that took place in Upper Austria and the MENA region.
