Penelitian ini bertujuan untuk melihat peranan penting dalam kehidupan manusia khususnya yang berhubungan dengan STEM. Setiap orang harus dilatih kemampuan spasialnya agar menjadi modal dalam memecahkan masalah dalam kehidupannya. Aspek-aspek kemampuan spasial belum memiliki definisi yang jelas karena setiap peneliti mengkategorikannya dengan berbeda-beda dengan istilah yang berbeda-beda pula. Walaupun demikian, penulis menyimpulkan bahwa ada 4 kelompok kemampuan spasial yang dirangkum dari berbagai macam pendapat tentang pengkategorian kemampuan spasial yaitu Spatial Visualization, Spatial Orientation, Dynamic Spatial Ability, dan Formal Spatial Ability. Dari berbagai cara yang dilakukan oleh para peneliti dalam melakukan dukungan kepada sesorang untuk memperbaiki kemampuan spasialnya, dapat dirangkum bahwa kemampuan spasial dapat ditingkatkan melalui pelatihan penyelesaian masalah kemampuan spasial, meakukan aktivitas yang melibatkan obyek-obyek geometri, dan melakukan pembelajaran geometri yang di dalamnya melibatkan aktivitas nyata, aktivitas menggambar dan aktivitas berbantuan komputer yaitu software geometri yang dinamis. Untuk dapat mendukung peningkatan kemampuan spasial siswa maka pembelajaran yang diberikan haruslah mendukung siswa untuk melakukan aktivitas nyata yang melibatkan obyek-obyek geometri yang bervariasi dan menggambarnya. Selain itu, dukungan juga dapat diberikan melalui pembelajaran yang menggunakan bantuan software geometri yang dinamis. Keterlibatan ketiga unsur ini harus dicari dalam pembelajaran yang akan dipilih atau didesain. Hal ini sebagai salah satu cara melakukan pendekatan bertahap mulai dari kongkrit, representasional, sampai dengan abstrak.Kata Kunciâ STEM, Kemampuan Spasial, Peningkatan, Software, Geometry.

ABSTRACT: The development of science and technology stimulates the rise of effort to make use of all facilities in all fields. One of the results is increasing number of computer use in Indonesia. This condition encourages educational practitioners to develop several models of learning media by using computers with purposes of tutorial, exercises, simulations, and games. Meanwhile, learning process which applies some media of simulation provides some benefits as they are realistic, secure, and simple. This simulation will lead students into a visualization of real life condition. Without media, students will usually imagine what they learn. It later exposes them with some problems that influence their abstractions. If a lecturer only explains about Transformation Geometry without using simulation, there is a big opportunity that students will yield misconception or they will only remember it with little understanding. This research aims to develop a valid and practical the Transformation Geometry simulation. The method in this research is a design research from a technology perspective that uses a preliminary stage and evaluation stage. The result presented the simulation of the definition of reflection, rotation, rotation half-round, and translations that have been made are in accordance with the curriculum and the existing concepts. Try-out result shows that the simulation can help students find their own concepts of reflection, rotation, rotation half-round, and translation; and sets up students to communicate. The conclusion of this research is that the result of simulation design that has been created has to be valid and practical.KEY WORDS: Development of Science and Technology; Computer Use; Transformation Geometry; Learning Process; Understanding of Concepts.Â Â About the Authors: Ahmad and Anton Jaelani are the Lecturers at the Department of Mathematics Education, Faculty of Education and Teacher Training UMP (Muhammadiyah University of Purwokerto), Jalan Raya Dukuhwaluh, Purwokerto, Central Java, Indonesia.

Technological improvements in the era of the Industrial Revolution 4.0 can be applied to learning mathematics as a medium of improving teacher performance. In addition, a pandemic situation forces teachers and students to implement online learning. One of the learning media that can help teachers in learning mathematics online is Socratic. The Socratic system generally consists of four basic components: acting humanely, thinking humanely, thinking rationally and acting rationally. For example, the Socratic can provide alternative solutions to the differential equations problems. Mathematics problems can be recorded by the Socratic through three main features:1) home screen, which is used to take pictures of solving the problem needed; 2) search results, the image that has been recorded will be searched for a solution through Socratic's artificial intelligence in internet database, and 3) an explanation, the search results that have been obtained, have their own explanation. Teachers and students as users may find the best solution for each explanation by the Socratic. Meanwhile, this study uses four stages of the literature review process:1) search for relevant literature, 2) evaluation and source selection, 3) identification of themes, and 4) outline of the structure of the writing. This paper systematically investigates the use of the Socratic as a technology application that can assist mathematical problems.

Ilmu memiliki arti pengetahuan dan agama Islam memiliki misi untuk menyebarluaskan ilmu pengetahuan. Dalam sudut pandang Islam, ilmu merupakan pengetahuan hasil usaha yang serius dalam segala permasalahan yang bersumber pada Al-Qur’an dan hadīts. Ilmu pengetahuan merupakan hal yang penting dalam kehidupan, salah satunya adalah matematika. Matematika juga tidak jauh dari Al-Qur’an dan hadīts, dimana diketahui banyak ayat-ayat Al-Qur’an yang menjelaskan konsep matematika. Selain itu, terdapat konsep matematika sekolah yang salah satunya ada pada ibadah shalat. Namun dalam matematika sekolah banyak materi yang belum terintegrasi dengan nilai-nilai keislaman. Tujuan penelitian ini adalah menganalisis unsur-unsur matematika dalam ibadah shalat yang bisa digunakan sebagai bahan ajar. Jenis penelitian yang digunakan adalah penelitian kualitatif dengan metode kajian literatur. Hasil dari penelitian ini konsep matematika sekolah dapat dihubungkan dengan materi ibadah shalat yang nantinya bisa digunakan sebagai bahan ajar untuk membantu siswa memahami materi tertentu pada matematika sekolah dan dapat membantu guru untuk mencapai pembelajaran matematika yang terintegrasi dengan nilai-nilai Islam.
