Keefektifan Scaffolding Berorientasi Keterampilan Berpikir Tingkat Tinggi pada Perkuliahan Fungsi Variabel Kompleks
Abstract
Effective learning becomes crucial to ensure that students can master higher-order thinking skills (HOTS), especially in the Complex Variable Functions course, which is one of the subjects requiring a deep understanding of abstract mathematical concepts and principles. The implementation of scaffolding in learning is one alternative to assist students in abstracting and constructing mathematical concepts and principles. This research aims to describe the effectiveness of implementing scaffolding oriented towards HOTS in Complex Variable Functions lectures. This research is a descriptive quantitative study conducted in the Mathematics Education study program at Universitas Negeri Medan, involving 46 sixth-semester students in the 2022-2023 academic year who were taking the Complex Variable Function course. The instruments used in this research were: 1) an expert assessment sheet on the effectiveness of scaffolding use; 2) a higher-order thinking skills test; 3) an observation sheet on learning time allocation; and 4) a student response questionnaire. The research results indicate that 1) the effectiveness of learning using HOTS-Oriented Scaffolding, based on expert assessments of theoretical mastery and experience, indicates that HOTS-Oriented Scaffolding can be effectively applied in mathematics learning in the classroom, meeting high criteria; 2) the effectiveness of learning using HOTS-Oriented Scaffolding, based on field data, includes a) high criteria for achieving higher-order thinking skills among students, b) high criteria for time allocation achievement, and c) an 86.33% percentage of students providing a positive response to learning components and activities. The results of this study indicate that the implementation of scaffolding has been proven effective in enhancing students' higher-order thinking skills. These findings can serve as a foundation for lecturers to adopt similar strategies in the learning process, both in curriculum design and in formulating policies to integrate interactive learning methods into courses within the analysis discipline.

Abstrak
Pembelajaran yang efektif menjadi krusial untuk memastikan bahwa mahasiswa dapat menguasai keterampilan berpikir tingkat tinggi, khususnya paada mata kuliah Fungsi Variabel Kompleks yang merupakan salah satu mata kuliah yang memerlukan pemahaman mendalam terhadap konsep dan prinsip matematis abstrak. Penerapan scaffolding daalam pembelajaran merupakan salah satu alternatif untuk membantu mahasiswa melakukan absraksi dan mengkonstruksi konsep dan prinsip matematis. Penelitian ini bertujuan untuk mendeskripsikan keefektifan penerapan scaffolding berorientasi pada keterampilan berpikir tingkat tinggi (scaffolding berorientasi HOTS) mahasiswa pada perkuliahan Fungsi Variabel Kompleks. Penelitian ini merupakan penelitian kuantitatif deskriptif yang dilaksanakan pada program studi pendidikan matematika Universitas Negeri Medan, yaitu pada 46 mahasiswa semester VI Tahun Ajaran 2022-2023 yang sedang mengikuti mata kuliah Fungsi Variabel Kompleks. Instrumen yang digunakan dalam penelitian ini adalah 1) lembar penilaian ahli tentang keefektifan penggunaan scaffolding, 2) tes keterampilan berpikir tingkat tinggi, 3) lembar observasi penggunaan waktu pembelajaran, dan 4) angket respon mahasiswa. Hasil penelitian menujukkan bahwa 1) keefektifan pembelajaran menggunakan scaffolding berorientasi HOTS ditinjau dari penilaian ahli berdasarkan penguasaan teori dan pengalamannya menyatakan scaffolding berorientasi HOTS dapat diterapkan secara efektif dalam pelaksanaan pembelajaran matematika di kelas berada pada kriteria tinnggi, 2) keefektifan pembelajaran menggunakan scaffolding berorientasi HOTS ditinjau dari data lapangan, yaitu a) kriteria pencapaian keterampilan berpikir tingkat tinggi mahasiswa berada pada kriteria tinggi, b) kriteria pencapaian penggunaan waktu pembelajaran berada pada kriteria tinggi, dan c) persentase banyak mahasiswa yang memberikan respon positif terhadap komponen dan kegiatan pembelajaran adalah sebesar 86.33%. Hasil penelitian ini mengindikasikan bahwa penerapan scaffolding terbukti efektif dalam meningkatkan keterampilan berpikir tingkat tinggi mahasiswa. Temuan ini dapat dijadikan sebagai landasan bagi dosen dalam mengadopsi strategi serupa dalam proses pembelajaran, baik dalam perancangan kurikulum maupun dalam merumuskan kebijakan untuk mengintegrasikan metode pembelajaran interaktif pada mata kuliah dalam rumpun analisis.
