Pemahaman Mahasiswa Terhadap Integral Sebagai Anti Turunan, Suatu Desain Riset Pada Kalkulus Integral

Abstract

The low learning outcomes and student’s difficulties in understanding calculus courses, espe-cially integral topic, encourage us as researcher to design a calculus lesson for first year students by using realistic mathematical approach (Realistic Mathematics Education). For that we try to design a series of instructional activities starting from understanding integral as an anti derivative. The in-structional activity is designed and developed based on the learning process that occurs in the class-room by involving 30 first year students in FMIPA UNP. The classroom learning compared with our Hypothetical Learning Trajectory (HLT). The results of teaching experiment show that students' un-derstanding of derivative plays important role in understanding the integrals, in general students have difficulty in communicating their ideas in determining the anti-derivative of a function. Through class-room discussions students can get ideas and discuss it in determining the anti-derivative of a function. Based on these results it is recommended to conduct classroom discussions to build students' under-standing in studying calculus especially integral as an anti derived.

“…In addition, learning outcomes focus on what is expected of students at the end of the lesson (Hung & Chou, 2015;Paolini, 2015;Setiawan & Basyari, 2017). This is in line with learning objectives, which describe the knowledge, abilities, skills, and attitudes that students must possess as a result of learning outcomes expressed in the form of observable and measurable behavior (Meda & Swart, 2018;Rao, 2020;Schoenfeld-Tacher & Sims, 2013) Tasman & Ahmad, 2017).…”

“…Elements of calculus consisting of limit, integral and derivative material have abstract characteristics (Shodikin, 2017;Tasman & Ahmad, 2017), so it requires a variety of mathematical abilities and requires an analytical and geometric understanding, causing most students to find it difficult to solve calculus problems (Hartati, 2019). Calculus must be taught to students at the formal cognitive development level if it is relevant to one's cognitive growth.…”

Analys of student contraints in completing integral topics

“…Realitanya masih banyak mahasiswa yang masih kesukaran dalam menyelesaikan persoalan integral (Rahmi dkk., 2020). Pemahaman konsep matematis dengan penggunaan rumusan atau formula juga dengan pendekatan matematik realistic dapat mendorong mahasiswa untuk membangun pemahaman mereka terhadap suatu konsep (Tasman & Ahmad, 2017). Artikel selanjutnya yang tebit tahun 2018 merupakan penelitian deskriptif kualitatif untuk mengetahui kemampuan menghitung integral tentu dan tak tentu dari fungsi aljabar sederhana serta aplikasinya dalam menghitng luas daerah di bawah kurva siswa kelas XII IPS SMA Syaichon Cholil Samarinda Tahun Ajaran 2017/2018.…”
