Peningkatan Kemampuan Pemahaman Konsep Matematika Menggunakan Model Problem Based Learning Pada Materi Pola Bilangan Di Kelas Viii SMP Negeri 3 Wertamrian Kabupaten Kepulauan Tanimbar

Abstract

This study aims to determine the learning design of speech pattern material for class VIII students of SMP Negeri 3 Wertamrrian using a problem based learning model and determine students' ability to understand mathematical concepts through number patterns after using a problem-based learning model for class VIII students of SMP Negeri 3 Wertamrrian. This research was conducted at SMP Negeri 3 Wertamrian, Tanimbar Islands Regency in November 2022. This type of research is a qualitative research using a research design. Data collection methods used are research documentation, written tests and interviews. The data analysis technique used is data reduction, data presentation and conclusions or verification. The results of the study design research using a problem based learning (PBL) model on Bialngan Pattern material in class VIII of SMP Negeri 3 Wertamrian are as follows: (a) In the first and second meeting learning, the researcher reviewed the material related to the learning objectives to be achieved. (b) The researcher gave 2 problems to students, namely 1 problem at the first meeting and 1 problem at the second meeting. Then ask students to check the sentences or questions contained in the problem that they have not understood. (c) Researchers divide students into groups to solve problems. (d) Researchers assist students in solving the problems given by providing the supports that have been provided in the HLT that the researchers designed. (e) Researchers provide opportunities for group representatives to present each problem that has been discussed. (f) Researchers together with students discuss and check the results of the discussions that have been presented and evaluate the learning process that occurs. (2) The ability to understand mathematical concepts of class VIII SMP Negeri 3 Wertamrian on number pattern material after following the mathematics learning process using PBL is as follows: (a) In problem 1, students have a more dominant concept understanding ability in indicators 1, 3 and 4, namely restating each concept, presenting the concept in various forms of mathematical representation and using, utilizing and selecting certain procedures or operations in solving problems. (b) In problem 2, students have more dominant concept understanding skills in indicators 1, 3 and 4, namely restating each concept, presenting concepts in various forms of mathematical representation and using, utilizing, and choosing certain procedures or operations in solving problems.

Analysis of Students' Mathematical Representation Ability in Solving Divergen Mathematics Problems in View of Gender Differences

“…Each mathematical ability has its own indicator which is used as a reference in research, while the indicators of repetition ability according to NCTM (2003, 2) are as follows: 1) use of repetition to model and intellectual interpretation of physical, social, and mathematical phenomena, 2) creative and use reipretation to organize, record, and communicate mathematical ideas, and 3) select, apply, and translate to slovei problems. From the explanation above, it can be explained that indicators of mathematical representation ability include 1) using representation (veirbal, symbolic and visual) to model and interpret physical, social, and mathematical phenomena, 2) creating and using verbal, symbolic and visual representations) to remember to communicate mathematical ideas and, 3) choosing to apply and translate mathematical representations (veirbal, symbolic and visual) to solve problems (Ratuanik, Mesak;Lolonlun,Blasius;Bacori, 2022). Minarni (2016) explained that mathematical representations can be reproduced in visual and non-visual representations.…”

“…This research type of literature study in this research was conducted to analyze the mathematical representational representation abilities of male and female students in solving different mathematics problems. Data Analysis Techniques The research was carried out using qualitative analysis techniques, namely quoting appropriate opinions (Ratuanik, Mesak;Lolonlun,Blasius;Bacori, 2022).…”

Implementation of Ethnomathematics of Tanimbar Coil Burning Using Pmri Approach to Circle Materials

“…The type of research that the researchers used in this study was an exploratory survey that led to a qualitative approach, Nassaji (2015) who stated that qualitative or descriptive research aims to describe a phenomenon with various characters with its scope. In this study, the researchers focused more on field observation data related to the use of the PMRI approach in the context of the Tanimbar stone-burning culture (Ratuanik, Mesak;Lolonlun,Blasius;Bacori, 2022). The research sample that the researchers used was class VIII SMP Negeri Kormomolin, Kormomolin District, Tanimbar Islands Regency.…”

“…The word mathematics describes a broad view of mathematics including computation or solving, arithmetic, classifying, sequencing, decision making and modeling (Ratuanik, Mesak;Lolonlun,Blasius;Bacori, 2022). The definition of Ethnomatematics according to Rosa & Orey, (Jakobus, et al: 2021) "the ethnomatematical practices of indentifiable cultural groups and may be regaaded as studies of mathematical ideas found in any culturewhich" means that "ethnomatematical practices from cultural groups that can be identified and can be arranged redefined as the study of mathematical ideas found in any culture (Matematika et al, 2022).…”
