Abstract

Eksplorasi ide sebagai bagian dari disposisi matematis memiliki peran penting bagi siswa. Dengan kemampuan eksplorasi ide, siswa akan mampu memecahkan soal matematika secara mandiri dan kreatif untuk mendukung keberhasilan pembelajaran matematika. Namun berdasarkan studi pendahuluan diketahui kemampuan eksplorasi ide siswa dalam menyelesaikan soal cerita materi pecahan masih rendah. Penelitian ini bertujuan mengembangkan instrument tes kognitif dengan membuktikan validitas dan reliabilitas konstruk instrumen tes eksplorasi ide materi pecahan di sekolah dasar. Metode penelitian ini adalah kuantitatif secara cross sectional dengan 307 siswa sebagai subjek penelitian. Analisis data menggunakan analisis faktor konfirmasi dengan software SPSS 26 dan Lisrel 8.80 untuk mengetahui nilai indeks daya beda dan nilai muatan faktor yang kemudian digunakan untuk menemukan nilai korelasi antar dimensi (AVE), validitas konstruk dan reliabilitas instrumen. Hasil penelitian menunjukan terdapat 12 butir soal valid secara konstruk dan reliabel. Penelitian ini memberikan implikasi dan rekomendasi dalam penggunaan instrument tes berbasis eksplorasi ide di sekolah dasar. Exploration of ideas as part of a mathematical disposition is essential for students. With the ability to explore ideas, students can solve math problems independently and creatively to support the success of learning mathematics. However, based on a preliminary study shows that student's ability to explore ideas in solving word problems on fractions is still low. This study aims to develop by proving the construct validity and reliability of the exploratory test instrument for ideas on fractional material in elementary schools. The method in this study was quantitative with a cross-sectional method with 307 students as research subjects. Data analysis was carried out by confirming factor analysis using SPSS 26 and Lisrel 8.80 software to determine the value of the differential index and factor loading values which can then be used to find the inter-dimensional correlation (AVE) values, construct validity, and instrument reliability. Of the 35 items, 17 questions have high discriminatory power to be analyzed using Lisrel 8.80. The results showed that 12 items were stated to be constructively valid and reliable. This study provides implications and recommendations for using test instruments based on idea exploration in elementary schools.

Abstract

Materi diferensial banyak digunakan sebagai prasyarat pada materi lain dan mata kuliah lain. Namun tidak sedikit mahasiswa yang merasa kesulitan dalam mempelajarinya. Oleh karena itu tujuan penelitian deskriptif kualitatif ini adalah mendeskripsikan kesalahan-kesalahan mahasiswa dalam menyelesaikan masalah diferensial berdasarkan teori Castolan. Teori Castolan meliputi kesalahan konsep, kesalahan prosedur, dan kesalahan teknik. Penelitian dilakukan terhadap mahasiswa peserta mata kuliah matematika dasar. Data dikumpulkan dengan metode tes dan wawancara dengan instrumen pendukung berupa tiga soal tes masalah deferensial dan pedoman wawancara. Data dianalisis dengan tahapan reduksi data, penyajian data, dan penarikan simpulan. Hasil penelitian ditemukan bahwa berdasarkan teori Castolan sebagian besar mahasiswa melakukan kesalahan strategi dan kesalahan hitung dan sebagian kecil melakukan kesalahan konsep. Kesalahan konsep terjadi saat mahasiswa salah menentukan rumus. Kesalahan strategi terjadi saat mahasiswa salah menggunakan rumus, tidak mampu menyelesaikan sampai bentuk yang sederhana serta ada data yang hilang. Sedangkan kesalahan hitung sebagian besar karena salah menulis atau menghitung. Adapun penyebab terjadinya kesalan tersebut karena kurang memahami konsep, belum terbiasa menyelesaikan soal yang membutuhkan memiliki keterampilan berpikir tingkat tinggi, serta kurang teliti Dengan mengetahui kesalahan serta penyebabnya dapat menumbuhkembangkan kreativitas dosen untuk mengatasi kesulitan yang dihadapi mahasiswa. Differential material is widely used as a prerequisite for other materials and other courses. But not a few students who find it difficult to learn it. Therefore, the purpose of this qualitative descriptive research is to describe students’ mistakes in solving differential problems based on the Castor theory. Castor’s theory includes conceptual errors, procedural errors, and technical errors. The research was conducted on students participating in basic mathematics courses. Data was collected by test and interview methods. The supporting instruments used were three differential problem tests and an interview guide. The student answers were then analyzed to see which represented the most errors. Test the validity of the data using technical triangulation. Data were analyzed with the stages of data reduction, data presentation, and drawing conclusions. The results of the study found that most students made procedural and technical errors, and a few made conceptual errors. Conceptual errors occur when students incorrectly determine the formula. Strategy errors occur when students use the wrong formula, are unable to complete a simple form, and there is missing data. While the technical errors are mostly due to wrong writing or counting. The cause of this errors is because they do not understand the concept, are not used to solving problems that require high-level thinking skills and are not thorough.

Abstract

Perlu dikembangkan model pembelajaran matematika di pesantren yang dikaitkan dengan permasalahan yang sesuai dengan situasi di pondok pesantren, misalnya terkait dengan fiqh. Penelitian ini menggunakan Design Didactical Research (DDR). Pengembangan desain didaktis ini dilakukan dengan menggunakan Theory of Didactical Situation (TDS). Pembelajaran matematika di pesantren dirancang sebagai berikut: pembacaan ayat suci Al-Qur'an dan Hadits terkait materi pembelajaran matematika; materi dan tujuan pembelajaran yang terkait dengan ilmu keislaman; dan memberikan gambaran tentang manfaat mempelajari materi yang akan dipelajari dalam kehidupan sehari-hari, terutama ketika nantinya menjadi kader ulama. Pengembangan desain didaktis didasarkan pada teori situasi didaktis, yaitu: Situasi Devolusi, santri diberikan tantangan untuk menyelesaikan masalah zakat dan waris; Situasi Matematis, santri yang belum mampu menyelesaikan tantangan utama dibimbing melalui soal, tabel, dan petunjuk. Demikian pula santri yang sudah memiliki tebakan pemecahan masalah terus melakukan langkah-langkah untuk menguji keabsahan asumsi tersebut dengan menjawab beberapa pertanyaan, memperhatikan tabel, dan melaksanakan instruksi; Situasi Kelembagaan, santri membuat kesimpulan dengan bimbingan guru tentang poin-poin penting. It is necessary to develop a mathematics learning model in pesantren that is associated with problems that are following the situation in the Islamic boarding school, for example, related to fiqh. This study used Design Didactical Research (DDR). The development of this didactic design was carried out using the Theory of Didactical Situation (TDS). The learning mathematics in pesantren is designed as follows: reading of the holy verses of Al-Qur'an and Hadith related to mathematics learning materials; the material and learning objectives associated with Islamic knowledge; and giving an overview of the benefits of studying the material to be studied in everyday life, especially when later becoming a cadre of the ulama. Didactic design development is based on the theory of didactic situation, namely: In the case of Devolution, santri are given the challenge of solving zakat and inheritance problems; in Mathematical Situations, santri who have not been able to complete the main difficulties are guided through questions, tables, and instructions. Likewise, santri, who already has problem-solving guesses, continues to test the validity of these assumptions by answering several questions, paying attention to tables, and carrying out instructions; 3) Situation of Institutionalization, santri makes conclusions with teacher guidance about essential points.
