Abstract

Abstrak Matematika merupakan mata pelajaran yang kontekstual dengan mempelajari pola dan struktur angka dan simbol. Pada tahun 2022 PISA mengungkapkan bahwa Indonesia menduduki peringkat ke 69 dari 80 negara. Hal tersebut dikarenakan masih rendahnya kemapuan numerasi siswa dalam proses pembelajaran. Salah satu faktor penyebabnya yakni minimnya penerapan media pembelajaran yang menarik oleh guru, sehingga tahap pembelajaran menjadi kurang efektif serta tak berjalan optimal. Penelitian ini bertujuan untuk meningkatkan kemampuan numerasi siswa dengan bantuan media pembelajaran berbasis teknologi yaitu Educandy. Penelitian ini menggunakan metode RnD dengan model ADDIE. Teknik pengumpulan data menggunakan teknik uji validitas media, validitas materi, observasi, pretest, postest dan angket. Subyek penelitian ini adalah siswa kelas III SDN Kemayoran 13 Jakarta sebanyak 22 siswa. Hasil dari penelitian ini yaitu Educandy dinyatakan dapat membuat proses pembelajaran menjadi efektif dan dapat meningkatkan kemampuan numerasi sebanyak 22,85%. Kata Kunci: Educandy; Media Pembelajaran; Numerasi; Pengembangan AbstractMathematics is a contextual subject by studying patterns and structures of numbers and symbols. In 2022 PISA revealed that Indonesia was ranked 69th out of 80 countries. This is due to the low numeracy skills of students in the learning process. One of the factors causing this is the lack of application of interesting learning media by teachers, so that the learning stage becomes less effective and does not run optimally. This study aims to improve students' numeracy skills with the help of technology-based learning media, Educandy. This research uses the RnD method with the ADDIE model. Data collection techniques used media validity, material validity, observation, pretest, postest and questionnaire.

Abstract

Interferensi berpikir merupakan fenomena yang terjadi ketika dua informasi tercampur dalam proses pemecahan masalah matematika, khususnya pada topik perbandingan senilai dan berbalik nilai. Fenomena ini penting untuk diteliti karena konsep perbandingan berkaitan erat dengan konsep matematika lainnya. Penelitian ini bertujuan untuk mengungkap terjadinya interferensi berpikir siswa dalam menyelesaikan masalah perbandingan senilai dan berbalik nilai. Subjek dalam penelitian ini terdiri dari dua siswa kelas VII A dan VII B yang terindikasi mengalami interferensi proaktif dan retroaktif. Penelitian ini dilaksanakan di MTs Sunan Kalijogo Kota. Metode penelitian ini adalah deskriptif kualitatif. Hasil dari penelitian ini menunjukkan intereferensi retroaktif terjadi ketika konsep perbandingan senilai dipengaruhi konsep perbandingan berbalik nilai. Hal tersebut dikarenakan kemiripan prosedur perbandingan senilai dan berbalik nilai. Akibantnya, siswa menggunakan prosedur perbandingan berbalik nilai dalam menyelesaikan permasalahan perbandingan senilai. Sedangkan, interferensi proaktif terjadi ketika konsep perbandingan senilai mempengaruhi konsep perbandingan berbalik nilai. Hal tersebut dikarenakan memori siswa terhadap perbandingan senilai lebih kuat daripada perbandingan berbalik nilai. Akibatnya, Akibantnya, siswa menggunakan prosedur perbandingan senilai dalam menyelesaikan permasalahan perbandingan berbalik nilai.In solving mathematics problems, sometimes students make errors caused by mixing two pieces  information. This phenomenon is known as interference. One of the problems can cause interference is the problem of directly proportional and inversely proportional. Interference in solving the problem of directly proportional and inversely proportional is importent to know because the concept of proportional is related to other mathematical concepts. This research aims to reveal the occurence of students’ thinking interference in solving the problem of directly proportional and inversely proportional. The subjects in this reserach consisted two of students in class VII A and VII B who had indications of experiencing proactive and retroactive interference. This research  was conducted at MTs Sunan Kalijogo Malang City from 1 to 30 september 2022. The research method is descriptive qualitative. The results of this research show that retroactive interference occurs when the concept of directly proportional is disturbed by the concept of inversely proportional. It is based on similarity the procedure in problem solving of directly proportional and inversely proportional. As a result, students use the procedure of inversely proprotional for solving the problem of directly proportional. While proactive interference when the concept of directly proportional disturbes the concept of inversely proportional.  This is because students' memory for direct proportion is greater than indirect proportion. As a result, students use the procedure of directly proprotional for solving the problem of inversely proportional.

Abstract

Kebingungan peserta didik dalam memecahkan soal-soal geometri disebabkan oleh tingginya tingkat abstraksi dari objek geometris dan kurangnya visualisasi benda yang dibayangkan. Media pembelajaran berbasis teknologi yang mampu membantu peserta didik untuk belajar visualisasi secara langsung yaitu Augmented Reality (AR). Teknologi AR dikolaborasikan dengan bahan ajar berupa Magicbook yang berisi marker AR, materi pembelajaran dan latihan soal. Hadirnya etnomatematika memberikan warna baru pada aktivitas pembelajaran peserta didik karena mengaitkan matematika dengan budaya. Budaya yang diangkat dalam penelitian ini adalah rumah adat Joglo karena struktur bangunan rumah Joglo merupakan representasi ilmu matematika materi bangun ruang sisi datar. Tujuan penelitian ini mengembangkan media MARI (Magicbook Augmented Reality) berbasis etnomatematika rumah adat Joglo untuk pembelajaran bangun ruang sisi datar di kelas VIII SMPN 2 Balen. Penelitian ini adalah jenis penelitian dan pengembangan dengan model ADDIE (analysis, design, development, implementation, dan evaluation). Hasil penelitian menunjukkan bahwa Magicbook Augmented Reality mendapatkan skor 3,82 (sangat valid) oleh ahli media dan mendapatkan skor rata-rata 3,50 (sangat valid) oleh dua ahli materi. Magicbook Augmented Reality juga dinyatakan sangat layak dengan hasil angket siswa yang menunjukan skor rata-rata 3,40. Simpulan penelitian ini adalah media MARI valid dan layak digunakan sebagai media pembelajaran matematika.Students’ difficulties in solving geometry problems are caused by the high level of abstraction of geometric objects and the lack of visualization of imagined objects. Technology-based learning media that can help students learn visualization directly is Augmented Reality (AR). In this study, AR technology is integrated with instructional materials in the form of a Magicbook containing AR markers, flat-sided solid geometry content, practice questions, and ethnomathematics components. The cultural element highlighted in this research is the Joglo traditional house, as its architectural structure represents concepts in flat-sided solid geometry. The aim of this research is to develop MARI (Magicbook Augmented Reality with Ethnomathematics) media based on the Joglo traditional house, which meets the criteria of being valid and feasible for teaching flat-sided solid geometry in Grade VIII at SMPN 2 Balen. This study employs a research and development (R&D) design using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results show that the Magicbook Augmented Reality received a score of 3.82 (very valid) from media experts, 3.75 (very valid) from the first subject matter expert, and 3.25 (very valid) from the second subject matter expert. In addition, the Magicbook was considered highly feasible by students, with an average questionnaire score of 3.40. It can be concluded that the MARI media is valid and feasible to be used as a mathematics learning media.

Abstract

Representation is an important element in mathematics learning that helps make abstract mathematical ideas more concrete. Changes between forms of representation, called translations of mathematical representations, are necessary in mathematics learning. However, students often struggle with this process, as evidenced by errors in problem-solving. These errors can be categorized into three types: interpretation errors, implementation errors, and preservation errors. Based on these facts, a solution is needed to overcome student errors. However, to formulate the right solution, an in-depth study is needed regarding student errors in translation. Therefore, this study aims to analyze and describe junior high school students' errors, especially in translating representations from symbolic to graphical form in quadratic function material. The method used is descriptive qualitative, involving three class IX students with different mathematical abilities as research subjects. The results of this study showed that high-ability students made few interpretation, implementation, and preservation errors from the stage of unpacking the source to constructing the target. Moderate-ability students made some interpretation and implementation errors from the stage of unpacking the source to constructing the target. Meanwhile, low-ability students made many interpretation, implementation, and preservation errors from the stage of unpacking the source to determining equivalence. To overcome these errors, teachers can apply level 1 scaffolding (environmental provisions) and level 2 scaffolding (explaining, reviewing, and restructuring). In conclusion, students with different mathematical abilities each have difficulties in making translations. The factors causing these errors include inaccuracy, neglect of important aspects, inappropriate habits, and conceptual errors.
