Abstract

This research is motivated by the low verbal representation ability of students of SMA N 8 Jambi City. The purpose of this research is to analyze students' mathematical verbal representation ability in solving open-ended problems on the material of Two-Variable Linear Equation Systems in phase E 4 of SMA N 8 Jambi City. This research uses a descriptive method with a qualitative approach. The subjects in this study were students of phase E 4 of SMA Negeri 8 Jambi City who had studied the material of Two-Variable Linear Equation Systems (SPLDV). The instruments used in this study were a test of mathematical verbal representation ability in solving open-ended type problems and interviews. Data analysis techniques were carried out by reducing data, presenting data, and drawing conclusions. Checking the validity of the data used triangulation techniques. The results of the study showed that students' verbal representation in solving open- ended problems, with representative subjects of students with high, medium and low abilities. Subjects S1 and S2 who have high verbal representation ability, tend to be more able to understand the problems from the questions and are able to show 3 (three) indicators of verbal representation ability, namely mathematical concepts, organization of ideas and expressions, while subjects S3 and S4 who have a moderate level of verbal representation ability show that the subjects are able to take the information in the questions and are able to show 2 (two) aspects of mathematical ability, namely mathematical concepts and organization of ideas. Meanwhile, subjects S5 and S6 who have a low level of verbal representation ability are not able to take information from the questions and can only show 1 (one) indicator, namely mathematical concepts.

Abstract

Literasi merupakan keterampilan penting yang harus dimiliki oleh setiap mahasiswa. Sebagian besar proses pendidikan bergantung pada kemampuan dan kesadaran literasi. Literasi merupakan proses yang kompleks yang membangun suatu pengetahuan dan budaya sebelumnya, serta pengalaman untuk mengembangkan pengetahuan baru dan pemahaman yang lebih mendalam. Literasi dideskripsikan sebagai kemampuan untuk memahami gambar serta bahasa dalam bentuk yang beragam untuk membaca, menulis, berbicara, mendengarkan, melihat, menyajikan dan berpikir kritis tentang sebuah ide. Dalam pembelajaran, kemampuan ini merupakan langkah awal yang sangat penting dalam keberhasilan proses pembelajaran yang produktif dikarenakan dengan kemampuan literasi yang baik mahasiswa memiliki daya serap yang baik terhadap informasi yang diperolehnya sehingga dapat menghasilkan gagasan-gagasan dan karya.

Abstract

Penelitian ini dilatarbelakangi oleh self efficacy siswa terhadap kemampuan komunikasi matematis siswa kelas XI MIPA SMA Negeri 9 Kota Jambi. Selama proses pembelajaran berlangsung di sekolah faktor yang mempengaruhi kemampuan komunikasi matematis siswa salah satunya, yaitu keyakinan siswa dalam mengkomunikasikan ide-ide matematis, atau disebut juga self efficacy. Self efficacy merupakan kayakinan diri yang dimiliki oleh setiap individu terhadap kemampuan yang dimilikinya dalam menghadapi dan menyelesaikan masalah yang dihadapinya. Penelitian ini bertujuan untuk mengetahui adanya pengaruh self efficacy terhadap kemampuan komunikasi matematis siswa.Jenis penelitian ini merupakan penelitian kuantitatif menggunakan uji regresi linear sederhana yang bertujuan untuk mengukur pengaruh yang signifikan antara self efficacy siswa terhadap kemampuan komunikasi matematis siswa. Populasi pada penelitian ini adalah seluruh siswa kelas XI MIPA SMA Negeri 9 Kota Jambi Tahun Ajaran 2022/2023 dengan jumlah keseluruhan 108 siswa yang terbagi menjadi 3 kelas. Sampel dalam penelitian ini berjumlah 51 siswa yang terbagi menjadi 3 kelas yang diambil secara random sampling (acak). Pengumpulan data dilakukan dengan pemberian angket dan tes uraian. Analisis data dilakukan dengan menggunakan bantuan program SPSS 21 terdiri dari analisis deskriptif, uji persyaratan analisis data, dan pengujian hipotesis. Uji persyaratan analisis data yang digunakan, yaitu uji normalitas, uji homogenitas, dan uji linearitas.

Abstract

Numeracy literacy skills are the most important part of the abilities that every student must have. The limited number of numeracy literacy instruments at SMP Negeri 2 Jambi is one of the factors causing less than optimal mathematics learning. Students are still lacking in understanding questions, formulating, identifying and interpreting mathematical problems properly and correctly. To train these abilities, an ethnomathematics-based numeracy literacy test instrument is needed. This research aims to describe the process of developing an ethnomathematics-based numeracy literacy test instrument and determine the validity index of the ethnomathematics-based numeracy literacy test instrument. This research is development research that adapts the Plomp model which consists of initial assessment stage, design stage, realization/construction stage, and test, evaluation and revision stage. Data collection techniques in this research are field note techniques, questionnaire techniques, validation techniques and test techniques with research instruments in the form of field note sheets, questionnaire sheets, validation sheets and test questions. Data analysis uses Aiken's formula and empirical validity uses product moment correlation. The results of this research show that at the design stage, there was a difference of opinion between the two validators regarding the grid, there was one indicator question that was not in accordance with basic competencies. These differences are then analyzed and revised according to input and suggestions from the validator. The researcher improved the question grid as well as the test questions, resulting in good question items, and the results of content validation by 4 expert validators calculated using the Aiken's formula obtained a validity value of 0.785. These results indicate that the ethnomathematics-based numeracy literacy test instrument is declared valid from three aspects, namely; materials, constructs and language.
