<![CDATA[Pemahaman konsep matematis merupakan kemampuan dasar yang sangat penting bagi siswa, namun kenyataan yang terjadi di lapangan pemahaman konsep matematis siswa masih rendah. Secara teori, pendekatan saintifik berbantuan Geogebra dapat meningkatkan pemahaman konsep matematis siswa. Penelitian ini bertujuan untuk mengetahui peningkatan dan perbedaan pemahaman konsep matematis siswa yang menggunakan pendekatam saintifik berbantuan Geogebra dan yang menggunakan pembelajaran biasa. Penelitian ini merupakan penelitian kuantitatif dengan metode eksperimen pada populasi siswa kelas XI MIA MA Negeri 1 Kerinci. Sampel penelitian ini adalah kelas XI MIA 1 sebagai kelas eksperimen dan kelas XI MIA 2 sebagai kelas kontrol yang dipilih melalui teknik random sampling. Instrumen yang digunakan adalah tes untuk mengukur pemahaman konsep matematis siswa. Untuk mengetahui peningkatan pemahaman konsep siswa digunakan rumus N-gain, sedangkan untuk mengetahui perbedaaan pemahaman konsep matematis siswa kelas eksperimen dan kontrol dilakukan uji-t. Hasil analisis data menunjukkan bahwa terdapat perbedaan signifikan peningkatan pemahaman konsep matematis siswa yang menerapkan pendekatan saintifik berbantuan Geogebra dan yang menggunakan pembelajaran biasa.The mathematical concepts understanding was a basic ability that must mastered by students. In the fact, the students’ mathematical concepts understanding was still low. By the thoery, the scientific approach assisted Geogebra can improve students' mathematical concept understanding. This research aims to determine the improvement and differences in mathematical concepts understanding of students who used scientific approaches assisted Geogebra and the students’ who used ordinary learning. This research was a quantitative research with experimental methods and eleventh-grade of science students (MIA) in MA Negeri 1 Kerinci as population. The sample of this study was XI MIA 1 students as an experimental group and XI MIA 2 students as a control group that selected through random sampling technique. The instrument used was test to mesaure the students’ mathematical concepts understanding. To determine the increasing of students’ mathematical concepts, N-gain formula was used. While t-test was used to determine the differences in mathematical concepts understanding of students in experimen and control group. The result of data analysis shown that there is the significant difference in students’ mathematical concepts understanding who used scientific approaches assisted Geogebra and the students’ who used ordinary learning. ]]>

<![CDATA[In facing current educational challenges, mobile learning can be an alternative solution to facilitate the teaching and learning process. It is mobile because mobile learning can be accessed via devices such as smartphones and tablets, which are almost always in the hands of students and teachers. However, to achieve effectiveness in developing mobile learning, needs analysis is essential. By conducting a needs analysis, we can understand the characteristics of the learner, learning materials, as well as the learning environment and conditions. The purpose of this article is to analyze the needs for developing mobile learning applications for learning mathematics for junior high school students on the topic of area and perimeter of quadrilaterals. This research is a descriptive exploratory study. The research subjects were seventh grade students at SMPN 4 Kerinci. A random sample of 15 students was selected. Data were collected using observation sheets of the mathematics learning process and student questionnaires. The observation results show that the mathematics learning material is still in the form of textbooks. The results of the needs analysis questionnaire show that students need learning media that can guide them to study independently by reviewing lessons anytime and anywhere in the form of mobile learning.]]>

<![CDATA[The Covid-19 pandemic has caused distance learning in Indonesia to not be optimal, with challenges for teachers, students and parents in terms of the effectiveness of online learning and the formation of student character. Student honesty in distance learning is an important concern for building integrity and good relationships with teachers and classmates. This study aims to evaluate the process of distance learning at SMPN 26 Kerinci, especially in the formation of students' honest character in mathematics. A qualitative case study approach was used, with data collection techniques in the form of observation and interviews. The results of observations of remote mathematics learning via Zoom show indications that it is necessary to increase the application of honest character of students, with some students turning off the camera, using substitute images, and cheating. Obstacles faced include teacher difficulties in ensuring student attention, lack of social interaction between students and teachers, and the impact felt by parents. Thus, more intensive efforts are needed to form the honest character of students in distance learning.]]>

<![CDATA[The use of technology in education is becoming increasingly common. So that in its development, educators must be able to take advantage of information and communication technology in the learning process. Efforts to use it are to increase the attractiveness of a learning process, one of which is by using the help of learning media. Because of this, this study aims to produce YouTube-based learning media on trigonometric comparison material, find out expert opinions and student responses to YouTube-based mathematics learning media on trigonometric comparison material from an angle. This research is a research development or Research and Development (R & D) using the Sugiyono procedure. This research was conducted at MAS Nurul Haq Semurup with the research subjects being students of class X. Data collection was carried out using interviews and questionnaires. The instrument used was a questionnaire using a Likert scale. Based on the results of the validation carried out by material experts and media experts, the percentage results were respectively 71% and 77% with valid criteria. Then the learning media was tested through 2 stages, namely small group trials and field trials. The average results obtained were 87.22% for small group trials and 88.16% for field trials with very practical interpretation criteria, so it can be concluded that YouTube-based mathematics learning media on trigonometric comparison material from an angle is valid and practical to use in learning. Overall the results of the study indicate that the learning media developed are suitable for use by students.]]>

<![CDATA[The Ferris wheel is one of the rides at the night bazaar and is often encountered by students. This is a potential for math learning. Through Realistic Mathematics Education (RME) approach, students learn mathematics with contexts close to students' lives as a starting point. Therefore, this study aims to design a learning trajectory using the RME approach with a Ferris wheel as a context in the learning process to support students' understanding of learning trigonometric comparison. The research method used is a type of design research called validation studies, which consists of three stages: preliminary design, design experiment, and retrospective analysis. The subjects of this study were 27 class X students from SMAN 3 Sungai Penuh. The instruments used are videos to see the learning process and when students work on the given problems, and photos to see the results of student work. The results of the study explored the learning trajectory practiced by using the Ferris wheel as a context, which is seen in students' daily activities. The learning trajectory consists of four activities, namely sketching a simpler Ferris wheel, redrawing the parts of the Ferris wheel where seats A and B are, measuring and comparing sides in a right triangle, and determining trigonometric comparisons.]]>
