This study aims to determine the feasibility of learning media electronic module (e-module) based on Kvisoft Flipbook Maker Pro on derivative material with Scientific approach using Research and Development research methodology. The study was conducted in two schools by taking 4 students as a student response in small classes and 20 students in a large class. The research instrument used in the form of evaluation formative form of teaching materials for material experts, media experts, and student responses. From the result of the assessment of expert material instrument obtained an average score of 101.25 with very good criteria, the assessment of expert media instruments obtained an average score of 116 with good criteria as well as on student response instruments obtained 86.44 with very good criteria. These results indicate that the e-module of mathematics with the scientific approach of the derived material for the XI class of the even semester high school is worthy of use in the process of learning in the classroom.

Some students have difficulty solving math problems in the integral calculus course, one of the materials for the volume of rotating objects. The purpose of this research is to describe the types of errors made by students of class F Mathematics Education FKIP Ahmad Dahlan University and their causes in solving the volume of rotating objects in integral calculus courses in the Polya stage. This research is a quantitative quantitative research. The research subjects are one class with a total of 20 students. For interviews, 3 students were taken with the criteria of high, medium and low abilities. Collecting research data using test material, the volume of rotating objects and student interviews about the factors that cause mistakes made. The steps for solving the problem consist of four stages, namely: understanding the problem, planning for completion, implementing the plan, and examining the solutions obtained. From the results of the research on student errors based on Polya's stages: 1) understanding the problem 55.89%, planning for completion of 50.00%, errors in implementing planning 32.36%, and errors in re-checking the process and results 44.12%; 2) the causes of students making mistakes in solving integral calculus questions on the volume of rotating objects, namely students lacking mastery in drawing function graphs, students lacking in basic concepts and volume formulas for rotating objects, and students unable to analyze the questions given.

Penelitian ini bertujuan untuk menganalisis jenis-jenis kesalahan mahasiswa dalam membentuk model matematika dan memecahkan masalah program linear dalam kehidupan sehari-hari berdasarkan teori Newman. Penelitian dilakukan dengan menggunakan pendekatan deskriptif kualitatif. Dari 28 mahasiswa kelas A semester V Prodi Pendidikan Matematika UAD Tahun Akademik 2019/2020 diambil 6 orang sebagai subyek penelitian. Tempat penelitian di kampus 4 UAD dan waktu penelitian pada semester gasal TA 2019/2020. Instrumen penelitian tes. Kesimpulan yang didapat dari hasil penelitian adalah: (1) 44,4% mahasiswa mengalami kesalahan membaca, karena kurang cermat dalam membaca (2) 44,4% mahasiswa salah memahami masalah, karena kurang memahami makna yang ada di dalam soal dan salah konsep (3) 33,3% mahasiswa membuat kesalahan transformasi, karena berawal dari pemahaman konsep yang salah. (4) 33,3% mahasiswa salah keterampilan proses, dan (5) 38,9% mahasiswa tidak dapat membuat kesimpulan dari jawaban yang diperoleh.

The teacher-centered learning causes less active students during the learning process. Application of learning method using cooperative learning model Quick on the Draw at the second grade students of SD Muhammadiyah Kleco III Yogyakarta can improve learning activities of the students. The Classroom Action Research conducted in three cycles, with the research object is 31 students. Data were collected using observation sheet  and interview session. Furthermore, data were analyzed using qualitative descriptive analysis. It is obtained that the percentage of student learning activities from Cycle I is 70.51% (good), Cycle II  is 78.56% (good) and Cycle III is 87.095% (very good). Based on the interviews, it is obtained that most of students are interested and feel happy in the learning of mathematics using cooperative learning model Quick on the Draw.

This research is motivated by the difficulty of students understanding the concept of integration techniques through bold learning, so that a concept understanding-based learning video is needed for flat area material. This study aims to develop learning videos and determine the validity and practicality of the videos produced. This type of research is in the form of ADDIE model development research (Analysis, Design, Development, Implementation, Evaluation). The research subjects were class B students, batch 2020, the Ahmad Dahlan University Mathematics Education study program. The results of the assessment from material experts obtained an average score of 4.77 with very good criteria, from material experts obtained an average score of 4.55 with very good criteria, and from student responses a score of 3.50 was obtained with good criteria so that it can be concluded that the video Integral calculus learning is valid and practical to use. Keywords: integral calculus, learning videos, trigonometric functions
