This research aims to analyze the feasibility of a problem-based digital pocketbook on the System of Two Variable Linear Equations (SPLDV) material developed in terms of its validity, attractiveness, practicality and effectiveness of use in facilitating mathematical problem-solving abilities. Product development using the ADDIE model was carried out in class VIII of SMP Negeri 7 Tulang Bawang Barat. Questionnaire and test techniques were used for data collection. The validation results for material experts obtained a score of 4.53, media experts 4.50 and language experts 4.36, which shows valid criteria. The average student response was 4.55 or interesting, and the teacher response was 4.83 or practical. From the evaluation results of students' mathematical problem-solving abilities after implementation, it is known that classical learning completeness reached 91% or very high. It can be concluded that problem-based digital pocketbooks are suitable for use as learning media to facilitate mathematical problem-solving abilities.

SYSTEMATIC LITERATUR REVIEW: KEMAMPUAN BERPIKIR KRITIS DENGAN MENGGUNAKAN PENDEKATAN PENDIDIKAN MATEMATIKA REALISITIK INDONESIA (PMRI)

Anggria Septiani Mulbasari — 2023-12-20

This study aims to conduct a literature review related to critical thinking skills using the PMRI approach. The method used is a systematic literature review (SLR). The data explored are articles related to Critical Thinking Ability Using the PMRI Approach for the period 2010-2021. From a number of articles that were traced from sinta 1 - 4, 8 articles were found that matched critical thinking skills using the PMRI approach. Based on the results analyzed, it can be concluded that using the PMRI approach can improve critical thinking skills, students are very enthusiastic in learning using the PMRI approach. Creative and innovative teachers using the PMRI approach can make learning mathematics fun, more interesting, less boring and liked by students. In addition, the application of learning with the PMRI approach, as well as the classroom atmosphere can improve critical thinking skills, and also have a direct impact on improving students' critical thinking skills and better student characteristics.

SYSTEMATIC LITERATURE REVIEW: PEMBELAJARAN PECAHAN MENGGUNAKAN PENDEKATAN PENDIDIKAN MATEMATIKA REALISTIK INDONESIA

This study aims to conduct a literature review related to fractional learning with the Indonesian Realistic Mathematics Education (PMRI) approach. The method used is Systematic Literature Review (SLR). The articles that were used as a source of review in this study were 9 articles related to the application and development of the PMRI approach to the material of fractions in the period 2017-2021. Articles come from reputable journals and are indexed by sinta and proceedings are indexed by scopus. From the results of the review, it was found that there were problems related to learning outcomes, understanding concepts, and the learning process on the material of fractions. The application and development of learning with the PMRI approach has a positive impact on the development of students' conceptual understanding of the fractional number material. Through the PMRI approach, students can develop fun learning situations, because learning activities are oriented to everyday concrete situations. The use of concrete media gives a good contribution in developing students' conceptual understanding of the fraction material. The developed learning trajectory can lay an important foundation in helping the development of the concept of fractions.

PENINGKATAN KEMAMPUAN BERPIKIR KRITIS MATEMATIS SISWA DENGAN MENGGUNAKAN PENDEKATAN PROBLEM POSING

The purpose of the study was to determine how the problem posing approach in learning mathematics can improve mathematical critical thinking skills. This type of research is Quasi experimental with Post Test Only Control Group design. The population in this study were VIII grade students of SMP Negeri 12 Bandar Lampung. The cluster random sampling method was used to select sample members from the population without considering the students' ability level. The results showed that the problem posing approach with steps to create mathematical situations, formulate mathematical questions, solve mathematical problems, and apply mathematical concepts has a relationship with indicators of mathematical critical thinking skills. Indicators of critical thinking skills include interpretation, analysis, evaluation, inference, explanation, and self-regulation. So, it can be concluded, students' mathematical critical thinking skills can be improved using the problem posing approach.

SYSTEMATIC LITERATURE REVIEW: PEMBELAJARAN SUDUT MENGGUNAKAN PENDEKATAN PENDIDIKAN MATEMATIKA REALISTIK

This research aims to conduct a literary review regarding corner learning using Indonesian Realistic Mathematics Education (PMRI). The method used is Systematic Literature Review (SLR). The data in this research is information on learning angles using (PMRI) taken from selected articles. The articles used as data sources in this research are 6 articles with the criteria being (1) the content being taught is about angles, (2) using the PMRI approach, (3) using the design research method, (4) the articles come from reputable and indexed journals. Sinta and Scopus. Based on the results of the study, it was found that (1) the initial problem in the research was students' misconceptions about the concept of angles, (2) the use of the PMRI context can bridge students in understanding the context of angles, (3) learning activities produce local instructional theory (LIT), (4) research results state that learning becomes more meaningful because students learn from real situations.

SYSTEMATIC LITERATUR RIVIEW: ASESMEN KOMPETENSI MINIMUM (AKM) PADA DOMAIN BILANGAN

Dian Meri Afrina — 2023-12-31

The Minimum Competency Assessment (AKM) is an assessment designed to measure the literacy and numeracy skills needed by all students in developing themselves and actively participating in society and to prepare students to face the 21st century. The urgency of developing math learning outcomes assessment questions by teachers or educators it is deemed necessary to prepare students to face various literacy tests both on a national and international scale. This development resulted in a variation of 4 items for number content with ascientific, cultural, and personal context. The questions developed are in the form of multiple choice and complex multiple choice which ask for evidence/reasons in answering the questions. The questions developed are valid based on the validity of the content carried out by fellow teachers. This development provides a variety of AKM practice questions and initial ideas for developing meaningful assessment of learning outcomes in a particular context.
