Abstract

Although many studies have involved fractions in the elementary school curriculum, research on this topic at the junior high school level has been limited, particularly in identifying the factors causing student learning difficulties and designing alternative didactic approaches to overcome these challenges. Therefore, this study aimed to investigate these aspects. Hermeneutic phenomenology was used in this study. The participants in this research were students from a junior high school in Lombok, Indonesia, consisting of 29 eighth-grade students (aged 14-18), most of whom were female and from the Sasak ethnic group. Instrument, such as fraction operation tests, in-depth interview guidelines, and a hybrid didactic design for mathematics learning. Data related to learning difficulties were analyzed using a thematic analysis approach with NVivo-12 software. The study's findings revealed that students' low ability to operate integers, especially multiplication and division, was a primary factor in learning difficulty. The hybrid mathematics learning design sequence consists of three stages. The first stage encompasses several activities, namely Let’s Guess and Let’s Read. The second stage involved activities like Let’s Search, Let’s Discuss, and Let’s Conclude. The third stage comprised activities of Let’s Practice and Self-Reflection.

Abstract

The industrial revolution 4.0 and the rapid advancement of technology during pandemic era has made significant progress in robot industry. There are three types of robots based on the level of independent control such as autonomous mobile robots, semi-autonomous mobile robots, and controller mobile robots. Semi-autonomous mobile robot and Controlled mobile still require human intervention in carrying out the tasks. In this study, teleoperation on mobile robots is displayed on various platforms such as Smartphone, Virtual reality headset as a virtual reality platform, and Computer (SVC) device. A camera is used as a visual sensor that dispatches the information of the surroundings to each platform. The controller used for the teleoperation varies depending on the platforms. The computer platform uses the arrow key on the keyboard. The smartphone platform uses touchscreen. Virtual reality uses Oculus Touch that has been integrated with Oculus Quest 2. ROS# as a robot API framework with Unity engine is used for the communication process between the robot and each platform. Teleoperation Experiments on SVC devices refer to four parameters including task completion rates, task time, satisfaction, and error counts. all these parameters will be combined into a single usability metric (SUM). The SUM results from SVC devices show 54.9% on Smartphones, 79.5% on VR devices, and 90.4% on Computers.

Abstract

Tuntutan kemampuan siswa dalam matematika tidak sekedar memiliki kemampuan berhitung saja, akan tetapi mampu menggunakannya dalam pemecahan masalah sehari-hari. Penelitian ini bertujuan untuk menganalisis kemampuan literasi matematis siswa kelas XI SMAN 1 Kediri. Metode penelitian yang digunakan adalah deskriptif kualitatif. Subjek penelitian terdiri dari 6 siswa dari 26 total siswa dalam 1 kelas. Penelitian ini memperhatikan faktor kemampuan awal matematis siswa (KAM). Berdasarkan hasil penelitian, 19% siswa tergolong kategori KAM tinggi dapat menyelesaikan soal rutin, menginterpretasikan masalah dan menyelesaikannya dengan rumus, melaksanakan prosedur dengan baik, mampu untuk mengatasi situasi yang kompleks serta menggunakan penalarannya dalam menyelesaikan masalah, serta siswa mampu bekerja secara efektif serta menginterpretasikan representasi yang berbeda kemudian menghubungkannya dengan dunia nyata (Level 4).Siswa yang tergolong kategori KAM sedang (66%)dapat menyelesaikan soal rutin, menginterpretasikan masalah dan menyelesaikannya dengan rumus, serta melaksanakan prosedur dengan baik (Level 3). Siswa dengan kategori KAM rendah (15%) hanya mampu menyelesaikan soal rutin (level 1). Demands on the ability of students in mathematics cannot just have the ability to count alone, but they can use it in solving everyday problems. This study aims to analyze the mathematical literacy ability of students at grade XI of SMAN 1 Kediri. The research method used was descriptive qualitative. The research subjects consisted of 6 students from 26 total students in 1 class. This study pays attention to the student's initial mathematical ability (IMA) factor. Based on the results of the study, 19% students who had high IMA could solve routine problems, interpret problems and solve them with formulas, carried out procedures well, we're able to overcome complex situations and used reasoning in problem-solving, and they were able to work effectively and interpreted representations that were different then connected it to the real world (Level 4). Students who had medium IMA (66%) were able to solve routine problems, interpreted problems and solved them with formulas, and carried out procedures well (Level 3). While students who had low IMA (15%) were only able to solve routine problems (level 1).
