Abstract

AbstrakMenyelesaikan masalah matematika pada topik turunan, masih dianggap sebagai soal yang sulit bagi mahasiswa karena berkaitan dengan banyak konsep matematika. Tujuan dari penelitian ini adalah untuk menganalisis kesalahan mahasiswa dalam menyelesaikan masalah turunan pada matakuliah Kalkulus. Penelitian ini dilakukan dengan menggunakan pendekatan kuantitatif dengan metode deskriptif. Populasi dan sekaligus sampel dalam penelitian ini adalah 70 mahasiswa yang mengambil mata kuliah Kalkulus. Pengumpulan data dilakukan dengan menggunakan tes dan wawancara. Tes disusun berdasarkan indikator pemecahan masalah matematis. Wawancara dilakukan untuk mendukung data lembar jawaban. Analisis lembar jawaban siswa berdasarkan Newmann`s Error Analysis (NEA). Hasilnya, kesalahan berdasarkan kategori NEA yang paling banyak dilakukan oleh siswa adalah Encoding, Process Skill, dan Transformation. Dengan demikian, dosen harus meminimalisir kesalahan dengan menerapkan soal non-rutin dan HOTS.Abstract.Solving mathematical problems in derivative topics, are still considered as a difficult matter for the students, because it’s related to many mathematical concepts. The purpose of this research is to analyze students’ error in solving derivative’s problem in Calculus. This research was conducted by using quantitative approach with descriptive method. Population and sample in this research were 70 students that took Calculus Course. The data was collected by using test and interview. The test was arrange based on mathematical problem solving indicators. The interview is conducted to support the answer sheet’s data. The analysis of students answer sheets are based on Newmann`s Error Analysis (NEA). The result is that the errors based on the NEA category which are mostly made by students are Encoding, Process Skill, dan Transformation. So that, lecturers should minimize the error by giving the non-routine and HOTS problems.

Abstract

Mathematics learning requires concrete evidence and examples in its implementation. This is often an obstacle experienced by teachers with a lack of mathematics learning media. This can lead to low student interest in mathematics. One of the materials that requires learning media in mathematics is geometry. However, the teacher's lack of ability to apply technology in mathematics learning hampers the learning process. One of the efforts that can be done is through community service aimed at SMP Mathematics teachers who are members of the Mathematics MGMP for SMP Kota Bukittingi. This training activity is structured in two stages, namely designing and building AR applications using Unity3D. This activity is carried out online which begins with providing an understanding of augmented reality technology, the modeling process using the Blender application, making markers and the Vuforia SDK to form AR and playmaker as programming, and the final stage is to create applications using unity software. Every stage of the activity is monitored and evaluated so that the activity is carried out properly. Based on the results of the service activities that have been carried out, it is concluded that the digital props based on Augmented Reality have been successfully created and help learning of geometry materialKunci: Mathematics learning, Augmented Reality, learning of geometry material.
