Abstract

Penelitian ini bertujuan untuk mengetahui kelayakan bahan ajar E-Modul interaktif berbasis TPACK untuk memfasilitasi kemampuan pemecahan masalah matematis siswa SMP pada materi aljabar dan untuk mengetahui respon siswa terhadap bahan ajar yang dikembangkan. Penelitian ini menggunakan metode Research and Development (R&D), dengan model ADDIE (Analysis, Desain, Development, Implementation, dan Evaluation). Instrumen penelitian yang digunakan adalah tes kemampuan pemecahan masalah, lembar validasi, dan lembar penilaian siswa. Teknik analisis data yang dilakukan adalah analisis data kualitatif dan analisis data kuantitatif yang diperoleh dari hasil validasi ahli, serta respon siswa terhadap E-Modul interaktif berbasis TPACK. Pada hasil data penelitian diperoleh bahwa bahan ajar E-Modul interaktif berbasis TPACK layak digunakan dengan tingkat kelayakan 91,6% yang berasal dari uji ahli media, 88,3% dari uji ahli pendidikan matematika dan 95% dari uji ahli matematika . Respon siswa pada uji lapangan baik mulai dari kelengkapan sudah sangat lengkap (63%), tampilan yang menarik (50%), kombinasi warna yang bagus (53%), bahasa yang mudah dimengerti siswa SMP bagus (57%), ilustrasi dapat mewakili materi Aljabar (57%), dan E-Modul dapat membantu kemampuan pemecahan masalah matematis (57%). Sehingga diperoleh kesimpulan bahwa bahan ajar E-Modul interaktif berbasis TPACK layak digunakan dan dapat membantu kemampuan pemecahan masalah matematis siswa kelas VII SMP.

Abstract

This study aims to determine the feasibility of LKPD teaching materials with the probing prompting learning model to facilitate the mathematical problem solving abilities of junior high school students on the flat-sided building material (cubes and blocks) and to determine student responses to the developed student worksheets (LKPD). This study uses research and development methods with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results of the research data obtained, and it can be concluded that the student worksheet (LKPD) of the probing prompting model is suitable for use with the results of the material test ( x = 33), mathematics education test ( x = 54), and media expert test ( x = 63). Student responses when viewed based on the results of the overall aspect value of the limited scale test, the value ( x = 45.71) is in the very feasible category. Meanwhile, the students' responses to the wide-scale (field) test based on the overall aspect scored (x  =46.81) with a very decent category.

Abstract

Exploring the decision-making abilities of undergraduate students, including students from vocational education backgrounds, is the main priority in the achievement of mathematics learning in general and in Calculus courses particularly. Decision-making processes require cognitive guidance through activities describing in detail the systematic steps of each process. It is implicitly said as part of a cognitive apprenticeship procedure. There are claims that students with a vocational education background can develop their academic and practical potential more through a cognitive apprenticeship model. In addition, using video as visual media learning allows students to sharpen their skills. Therefore, the study aims to explore the distinction in achievement and improvement of mathematical decision-making skills between undergraduate students who learn with a Video-assisted Cognitive Apprenticeship approach (CAV), and they are who receive Cognitive Apprenticeship learning (CA) with conventional learning. A quantitative study with the Static-Group Pretest-Posttest Design was employed as a methodology in the research. Based on the research stage, there are differences in achievement and improvement of student decision-making skills with a review of the type of vocational school between undergraduate students.

Abstract

Fungsi Kuadrat merupakan salah satu konsep Kalkulus yang banyak bersinggungan dengan kebutuhan kemampuan mathematical visual thinking. Kemampuan tersebut dipandang penting terutama untuk mengubah semua jenis informasi ke dalam gambar, grafik, atau bentuk-bentuk lain yang dapat membantu mengomunikasikan informasi secara lebih detil dan terlihat. Tetapi dalam perkembangannya, media pendukung belajar untuk mengembangkan kemampuan mathematical visual thinking masih terbatas khususnya pada pendalaman konsep Fungsi Kuadrat. Dengan demikian perlu adanya media belajar berupa worksheet untuk memenuhi kebutuhan eksplorasi konsep Fungsi Kuadrat baik prosedural maupun visual yang valid dan reliabel. Oleh karena itu, fokus kerja penelitian adalah mengembangkan worksheet graphing quadratics berbantuan Phet Simulation untuk pemberdayaan mathematical visual thinking mahasiswa. Penelitian pengembangan diaplikasikan sebagai pendekatan penelitian dengan tahapan penelitian mulai dari analisis dan desain, pengembangan prototipe dan uji kelayakan prototipe. Sebanyak 93 mahasiswa menjadi partisipan penelitian. Uji kelayakan validator menghasilkan nilai p-value > 0,05 yang menandakan ada pertimbangan yang seragam dari validator untuk jenis validitas muka dan validitas isi prototipe yang diujikan. Implikasi hasil tersebut dapat dinyatakan bahwa worksheet graphing quadratics layak digunakan untuk mengukur dan mengoptimalkan kemampuan mathematical visual thinking.

Abstract

Applying a graphing quadratic worksheet as a medium for learning the concept of a Quadratic Function clearer is an alternative instrument to accommodate the needs of developing students' mathematical visual thinking. In implementing graphing quadratic worksheet should show details of the dominant and recessive visual thinking classification aspects that develop in students. Classification of dominant and recessive aspects of visual thinking needs to be completed to determine stages in improving the worksheet and learning instructions that are applied especially to recessive aspects. Therefore, there is a need to evaluate the factors and trace the classification aspects of visual thinking that developed in students after practicing the graphing quadratic worksheet. The purpose of this research is to determine the categorization aspects of visual thinking in graphing quadratic worksheet items that develop and do not develop in students. Confirmatory factor analysis was employed as a research method on 12 sub-variables from the three classifications of visual thinking. As research data, 93 student records were used. Four main factors were formed as a result of the confirmatory factor analysis procedure, with the top two factors, namely factors 1 and 2, completely representing each aspect of the visual thinking classification and achieving the factor loading significance criteria. The implication is that the variables developed in the graphing quadratic worksheet for each aspect of the visual thinking classification have a strong relationship with the visual thinking ability overall. Enhanced by a cumulative variance value for factors 1 and 2 specifically 56.88% of the total 81.78% for all factors. Thereby it can be said that the categorization aspect of visual thinking that develops in students after implementing a graphing quadratic worksheet is achieved sensibly.
