Tingkat Pemahaman Konsep Mahasiswa Pendidikan Fisika Universitas Sebelas Maret pada Materi Momentum

Abstract

<p class="AbstractEnglish"><strong>Abstract: </strong>Understanding concepts on the momentum material owned by students is vary. Some students have understood the concept in accordance with scientific truth, but some are not yet. Constraints experienced by students in understanding the concept can lead to misconception. This study aims to analyze the level of understanding of student concepts on the momentum material by using qualitative descriptive method. The subjects of this research are 33 students of Physics Education of Sebelas Maret University who have not received Basic Physics course. Data were collected by tests and interviews. The results showed that 77.27% of students experienced misconceptions on the transfer of energy of mutually colliding objects. Momentum and impulse materials have been taught in the XI Senior High School, though most students have not understood the concept as a whole.</p><p class="KeywordsEngish"> </p><p class="AbstrakIndonesia"><strong>Abstrak: </strong>Pemahaman konsep pada materi momentum yang dimiliki mahasiswa berbeda-beda. Sebagian mahasiswa sudah memahami konsep sesuai dengan kebenaran ilmiah, namun ada juga yang belum. Kendala yang dialami mahasiswa dalam pemahaman konsep tersebut dapat menimbulkan terjadinya miskonsepsi. Penelitian ini bertujuan untuk menganalisis tingkat pemahaman konsep mahasiswa pada materi momentum dengan menggunakan metode deskriptif kualitatif. Subjek penelitian yang digunakan adalah 33 mahasiswa Semester 1 Pendidikan Fisika Universitas Sebelas Maret yang belum menerima mata kuliah Fisika Dasar. Data dikumpulkan dengan tes dan wawancara. Hasil penelitian menunjukkan 77,27% mahasiswa mengalami miskonsepsi pada transfer energi benda yang saling bertumbukan. Materi momentum dan impuls sudah diajarkan di kelas XI SMA, meskipun demikian sebagian besar mahasiswa belum memahami konsep secara keseluruhan.</p>

Pengembangan Instrumen Tes Kemampuan Berargumentasi Pada Materi Impuls Dan Momentum

“…Menurut hasil penelitian (Karim dkk., 2015;Rhahim, dkk., 2015) bahwa jenis kesalahan yang dilakukan mahasiswa dalam mneyelesaikan soal-soal pada materi impuls dan momentum adalah kesalahan strategi mengerjakan, kekeliruan berpikir terkait keberlakuan hukum kekekalan momentum, dan kesalahan konsep. Menurut (Rosa, Cari, & Aminah, 2017) dalam penelitiannya menunjukan mahasiswa mengalami miskonsepsi terhadap transfer energi yang saling bertumbukan sebesar 77.27%. Berdasarkan hal tersebut, penelitian ini dilakukan dengan tujuan yaitu mengembangkan instrumen tes model Toulmin's Argument Pattern (TAP) berupa soal uraian yang digunakan untuk mengukur kemampuan berargumentasi mahasiswa Pendidikan Fisika di Universitas Negeri Malang.…”

Analysis of Momentum and Impulse Misconceptions of College Students Using Four-Tier Diagnostic Tests

“…This is in accordance with previous research conducted by Geraldine Cintia Rosa, namely the first object will stop right at the initial position of the second object, and only the second object will move with the same speed as the initial velocity of the first object, this can occur because of the energy The kinetic energy of the first object is completely transferred to the second object, if the second object has the same mass as the first object then the velocity of the second object and the first object is the same, whereas when the first and second objects stick together and move together, the kinetic energy of the two objects will be lost at the second time. the object undergoes a perfectly elastic collision (Rosa et al, 2017).…”

Online-Based Assessment of Students’ Conceptual Understanding of Energy and Momentum Using Quizizz

“…The lack of understanding of physics concepts experienced by students is caused because there are still students who understand some concepts as misconceptions [11,[17][18][19]. Some students still think that the object's speed depends on the shape of the object's trajectory.…”
