Abstract

Computational thinking is the process of solving problems using logic gradually and systematically needed in the field of mathematics. However, the learning applied by the teacher limits the student's ability to develop computational thinking skills. Teachers are accustomed to providing conventional learning and emphasize student's skills in using formulas. One of the treatments that can be used to stimulate student's computational thinking skills is PISA questions. The purpose of this study was to analyze student's computational thinking processes in solving PISA questions in terms of their problem solving abilities. The research data consisted of student answers, think aloud results, and semi-structured interviews. Data analysis techniques are data reduction, data presentation, and drawing conclusions or verification. The results showed that the computational thinking process of students with low problem solving abilities only reached the decomposition stage because students were able to simplify the problem even though it was incomplete, but they were not able to connect mathematical concepts or materials to build a solution. Meanwhile, students with moderate and high problem solving abilities are limited to the pattern recognition stage because they can simplify problems and develop strategies, but make mistakes in using patterns, and there are incomplete steps. So it can be concluded that the computational thinking process of students with low problem solving abilities only reaches the decomposition stage. The computational thinking process of students with moderate and high problem solving abilities is limited to pattern recognition indicators.

Abstract

Struktur berpikir merupakan refresentasi internal dari aktifitas mental siswa yang menggambarkan alur penyelesaian masalah matematika. Struktur berpikir ialah salah satu faktor yang mempengaruhi kesalahan penyelesaian masalah matematika siswa. Oleh karena itu, kesalahan yang dilakukan siswa dalam menyelesaikan masalah matematika, membutuhkan solusi yang tepat, salah satunya dengan melakukan defragmentasi. Tujuan penelitian ini adalah untuk melakukan defragmentasi struktur berpikir siswa sekolah menengah pertama terhadap kesalahan membaca berdasarkan teori newman dalam menyelesaikan masalah matematika. Pendekatan yang digunakan dalam penelitian ini adalah kualitatif dengan jenis penelitian deskriptif. Pemilihan subjek dilakukan dengan teknik purposive sampling dengan kriteria, yaitu siswa yang memiliki kesalahan membaca (reading error). Data penelitian terdiri atas jawaban, rekaman hasil wawancara semi terstruktur dan hasil think aloud siswa. Adapun teknik analisis yaitu mereduksi data, menyajikan data, dan menarik kesimpulan. Hasil penelitian menunjukkan bahwa defragmentasi dapat membantu siswa untuk menata ulang struktur berpikir yang dimiliki. Hal ini dibuktikan dengan lengkapnya struktur berpikir siswa dari tahap menafsirkan/memahami, menerapkan, menganalisis, dan mengevaluasi.

Abstract

The structure of thinking is an internal representation of students' mental activity that describes the flow of solving mathematical problems. The structure of thinking is one of the factors that influence students' math problem solving errors. Therefore, mistakes made by students in solving math problems require the right solution, one of which is defragmentation. The purpose of this study was to defragment the thinking structure of junior high school students towards reading errors based on Newman's theory in solving math problems. The approach used in this research is qualitative with descriptive research type. Subject selection was carried out by purposive sampling technique with criteria, namely students who had reading errors and understanding errors. The research data consisted of answers, recordings of semi-structured interview results and students' think aloud results. The analysis techniques are reducing data, presenting data, and drawing conclusions. The results of the research show that defragmentation can help students to rearrange their thinking structures. This is evidenced by the complete structure of students' thinking from the stages of interpreting/understanding, applying, analyzing, and evaluating.

Abstract

This research was motivated by students' lack of ability to understand mathematical concepts, students also had difficulty understanding what was conveyed by the teacher in class. Therefore, the aim of this research is to analyze students' understanding of mathematical concepts based on a guided discovery learning model (Discovery Learning) on algebraic material. This research was carried out at SMPN 2 Praya Timur. The subjects of this research were class VII, while the samples used were class VII B as the control class and class VII A as the experimental class. The instruments used in this research are the Learning Implementation Plan (RPP) with the Discovery Learning learning model and a written test in the form of essay questions with material in algebraic form. This research is a quantitative type of experimental research, the form is The Non Equivalent Control Group Design. Data analysis using the t test using the separated variance formula shows the results of the t test i.e then rejected. In this way, the results of this research are that the guided discovery learning model (Discovery Learning) is effective on students' ability to understand mathematical concepts at SMPN 2 Praya Timur.

Abstract

This research was conducted to obtain an overview regarding the influence of the Jigsaw type cooperative learning model in mathematics learning in terms of students' creative thinking. The type of research used is experimentation with a quantitative approach. The sample in this study was taken using a saturated sampling technique with 25 students as an experimental class taught using the Jigsaw type cooperative learning model and 24 students as a control class taught using conventional learning. The instrument for collecting data is a questionnaire. The data normality test uses the Liliefors test and the homogeneity test uses Fisher. Hypothesis testing using the t test, shows tcount (2.73) > ttable (2.01) with ???? = 0.05 which states that ???????? is rejected, so it can be concluded that there is a significant influence on the Jigsaw type cooperative learning model in mathematics learning in terms of review. from students' creative thinking

Abstract

This study was conducted to evaluate curriculum implementation in 12 public junior high schools in Mataram City, focusing on the role of teachers in the dynamics of learning. Using descriptive method and quantitative approach, this study details the features of curriculum implementation, including planning, flow of learning objectives, learning and assessment, use of teaching materials, and Pancasila learning project. The evaluation shows that most parts of the curriculum have been realized, but further adjustments are needed to the guidelines provided by the Ministry of Education and Culture and the Ministry of Research and Technology. Certain areas, such as the use of project modules, require improvement in the utilization of existing resources. Collaboration between teachers, with parents/community/industry, and evaluation/reflection on the curriculum are important aspects of this implementation. However, more structured evaluation is needed to improve the quality and effects of Merdeka Curriculum. Although the implementation stage has gone well, the evaluation highlights that there is room to improve skills and more optimal effects in the learning process. This research provides an overview of the curriculum implementation after one year and identifies areas that require further attention to improve the student learning experience
