Abstract

Salah satu kemampuan abad 21 yang perlu dikembangkan dalam dunia pendidikan adalah berpikir komputasi. Pengembangan kemampuan berpikir komputasional perlu memperhatikan faktor yang mempengaruhi, contohnya adalah Mathematics self-concept (MSC) dan Kemampuan Awal Matematika (KAM). Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir komputasional dengan perbedaan MSC pada siswa dengan KAM tinggi. Metode dalam penelitian ini adalah kualitatif deskriptif. Kemampuan berpikir komputasional terdiri atas empat komponen, yaitu dekomposisi, abstraksi, pengenalan pola, dan berpikir algoritmik. Teknik pengumpulan data penelitian menggunakan instrumen tes dan wawancara. Teknik analisis data meliputi reduksi data, penyajian data dan penarikan kesimpulan. Berdasarkan penelitian diperoleh bahwa perbedaan MSC siswa sangat berpengaruh terhadap kemampuan berpikir komputasional yang dimiliki siswa. KAM juga berperan penting pada saat proses pengenalan pola dan berpikir algoritmik. MSC positif dan KAM tinggi memampukan siswa melakukan semua komponen berpikir komputasional, sedangkan MSC negatif menjadi kendala karena siswa kurang antusias dan tidak mau memperbaiki jika kesalahan terjadi. Saran untuk penelitian selanjutnya yaitu perlu dilakukan pengembangan kemampuan berpikir komputasional dengan sebelumnya meningkatkan KAM dan MSC siswa.

Abstract

Berdasarkan hasil diskusi yang dilakukan bersama dengan Dinas Pendidikan Kabupaten Sukabumi, masih banyak permasalahan-permasalahan yang ditemukan dalam pembelajaran di kelas, misalnya pembelajaran berjalan satu arah hanya dari guru kepada peserta didik, metode yang digunakan kebanyakan ceramah sehingga suasana pembelajaran menjadi bosan, pemilihan media pembelajaran monoton dan tidak variatif, motivasi belajar peserta didik rendah, serta kurangnya perhatian peserta didik selama proses pembelajaran. Maka dari itu tim pengabdian melakukan pelatihan kepada guru menengah di SMPN 1 Sukaraja agar dapat menciptakan pembelajaran yang menarik dan interaktif dengan menggunakan Aplikasi ClassPoint. Metode yang diterapkan dalam kegiatan pelatihan ini adalah metode presentasi mengenai pengenalan software, kemanfaataannya, dan penerapannya dalam pembuatan media pembelajaran interaktif, serta metode demonstrasi mengenai pengoperasionalisasian program. Terdapat kendala dalam pelatihan yaitu kurangnya waktu yang diberikan dan akses jaringan yang sulit. Based on the results of discussions held together with the Sukabumi District Education Office, there are still many problems found in classroom learning, for example learning goes in one direction only from the teacher to the students, the method used is mostly lectures so the learning atmosphere becomes bored, the choice of learning media monotonous and not varied, low student learning motivation, and lack of student attention during the learning process. Therefore, the service team conducted training for secondary teachers at SMPN 1 Sukaraja so they could create interesting and interactive learning using the ClassPoint Application. The method applied in this training activity is a presentation method regarding the introduction of software, its benefits, and its application in creating interactive learning media, as well as a demonstration method regarding the operationalization of the program. There are obstacles in training, namely the lack of time given and difficult network access.

Abstract

Mistakes frequently occur among students when interpreting mathematical problems or engaging with math exercises. This has contributed to the low PISA results in 2022, particularly reflected in a decline in mathematical proficiency, with Indonesia's average score decreasing by 1-3 points compared to previous assessments. Consequently, there is a pressing need to investigate the errors committed by students. This study aims to identify student errors through the lens of Newman's theory while addressing critical thinking ability questions in relation to cognitive style. The research design is descriptive qualitative, as it elucidates the mistakes made by students. The subjects of this study comprised 27 out of 84 seventh-grade students from SMP Negeri 139 Jakarta, who exhibited errors in responding to critical thinking ability questions involving combined material on flat-sided geometric shapes. The findings and conclusions of this study reveal that students with a Field Dependent (FD) cognitive style and those with a Field Independent (FI) cognitive style encounter reading errors, understanding errors, process skill errors, and coding errors; however, students with an FI cognitive style tend to make fewer mistakes than their FD counterparts.
