Abstract

This research aims to analyze how students' ability to understand problems in story problems is seen from the concrete sequential thinking (SK) style. The research subjects consisted of three class VII students at SMPN 5 Moyo Hilir who had a concrete sequential thinking style that came from their respective abilities in understanding low, medium, and high categories of mathematical problems. The research approach used is descriptive qualitative with data collection methods including questionnaires, tests, and interviews. Questionnaires are used to classify students' thinking styles. Students who fall into the SK thinking style category are given a written test to determine their ability to understand students' problems. Written test results are confirmed through interviews with students. The research results showed that students with a high and moderate ability to understand problems answered questions systematically and in detail according to the characteristics of SK's thinking style. Students with a high ability to understand problems can determine each element that is known and ask about the problem precisely and clearly. Students with the ability to understand the problem still have writing errors but can understand the problem correctly. Students with a low ability to understand problems are not able to understand all the questions correctly due to a lack of understanding of concepts related to social arithmetic material. The process of problem solving is not systematic and irregular, so it does not match the characteristics of a concrete, sequential thinking style.

Abstract

University students are required to possess critical thinking skills to face the challenges of the 21st century. However, preliminary observations of first-semester students in the Mathematics Education Program at STKIP Paracendekia NW Sumbawa indicate that their critical thinking skills remain low. To address this issue, the flipped learning model was implemented. This study aims to develop flipped learning-based teaching materials to foster students’ critical thinking skills. The research employs a development approach using the Four-D (4D) model, limited to the product validity testing stage. Data collection techniques include questionnaires, observations, interviews, and tests. The data were analyzed using descriptive qualitative and quantitative methods. The results show that the developed teaching materials include activities aligned with 12 critical thinking indicators and support independent learning. Validation by three experts indicated a validity level of 92.80%, categorized as highly valid. This module can be used in early-semester learning as a means to enhance students’ critical thinking skills and independent learning abilities.

Abstract

This study aims to produce an applicable Sumbawa local wisdom-based mathematics module for elementary school students by using the Four-D (4D) development research design from Thiagarajan. However, the development design of this module only includes three steps, namely define, design, and develop. The product feasibility test is only on the aspect of validity. Observation, interviews, and questionnaires were used to collect the data. The defined stage resulted in the formulation of the material, including the KPK, FPB, Fractions, Two-dimensional Shapes, and three-dimensional Geometry. A draft was created by emerging the elements of Sumbawa local wisdom in the materials, which is then validated at the design stage. The average validation results of material experts were 91.678%, linguists 90%, and media experts were 91.15%. The average validation result of the three specs is 90.94%, categorized as very valid, which confirms that the module is valid and suitable for elementary school students.Penelitian ini bertujuan untuk menghasilkan modul matematika berbasis kearifan lokal Sumbawa yang valid untuk siswa sekolah dasar dengan menggunakan desain penelitian pengembangan Four-D (4D) dari Thiagarajan. Namun, desain pengembangan modul ini hanya meliputi tiga langkah yaitu define, design, dan develop. Pada tahap develop, uji kelayakan produk hanya pada aspek kevalidan. Teknik pengambilan data meliputi observasi, wawancara dan angket. Hasil penelitian pada tahap define yaitu perumusan materi yang meliputi KPK, FPB, pecahan, bangun datar dan bangun ruang.  Hasil penelitian pada tahap design yaitu memunculkan unsur kearifan lokal Sumbawa pada materi sehingga menghasilkan draf modul matematika berbasis kearifan lokal Sumbawa untuk divalidasi. Hasil validasi diperoleh bahwa rata-rata hasil validasi ahli materi 91.67%, ahli bahasa 90% dan ahli media 91.15%. Rata-rata hasil validasi ketiga spek yaitu 90.94% dan dikategorikan sangat valid, sehingga dapat disimpulkan bahwa modul matematika berbasis kearifan lokal Sumbawa dikatakan sangat valid dan layak digunakan oleh siswa sekolah dasar.
