Mathematical media is one of the keys to the success of achieving mathematics learning goals. Learning mathematics will be more effective when using mathematical media in the process. The use of mathematical media in the learning process is not just about attracting students' interest and attention, but the media is a bridge to explain abstract mathematical concepts. Mathematical media functions as concrete modeling of mathematical concepts. The average elementary school teacher Mardi Waluya, has an old paradigm in carrying out mathematics learning. Mathematics is taught starting from concepts, formulas, and then applied in story problems as a model of problems in everyday life. This way of learning makes students experience boredom and even does not like learning mathematics. The use of mathematical media in learning is still less varied. The use of mathematical media is usually only on certain concepts or material. The development of mathematical media is less done because the teacher does not know how the media was developed to explain a mathematical concept. Mathematics media development training conducted with PGSD, Unika Atma Jaya has greatly assisted teachers in developing ideas about mathematical media. The activities in the training aim to make the teacher understand the important things needed to develop mathematical media. Teachers are invited to experience how easy it is to learn mathematics by using mathematical media that has been prepared by the resource person. Every activity recognized by the teacher is able to inspire the teacher in developing mathematics media. Examples of how to make and use mathematical media provided are very helpful for teachers in creating mathematical media by utilizing simple materials and tools. But the teachers also hoped for further training, both related to the mathematics media and learning methodsABSTRAKMedia matematika merupakan salah satu kunci keberhasilan pencapaian tujuan pembelajaran matematika. Pembelajaran matematika akan lebih efektif apabila menggunakan media matematika dalam prosesnya. Penggunaan media matematika dalam proses pembelajaran bukanhanya sekedar menarik minat dan perhatian siswa, namun media menjadi jembatan untuk menjelaskan konsep matematika yang bersifat abstrak. Media matematika berfungsi sebagai pemodelan konkrit konsep matematika. Rata-rata guru SD Mardi Waluya, memiliki paradigma lama dalam melaksanakan pembelajaran matematika. Matematika diajarkan mulai dari konsep, rumus, dan kemudian diaplikasikan dalam soal cerita sebagai model masalah dalam kehidupan sehari-hari. Cara pembelajaran yang demikian membuat siswa mengalami kebosanan bahkan menjadi tidak suka belajar matematika. Penggunaan media matematika dalam pembelajaran masih kurang variatif. Penggunaan media matematika biasanya hanya pada konsep atau materi tertentu saja. Pengembangan media matematika kurang dilakukan karena guru tidak tahu bagaimana media dikembangkan untuk menjelaskan suatu konsep matematika. Pelatihan pengembangan media matematika yang dilakukan bersama PGSD, Unika Atma Jaya sangat membantu guru dalam mengembangkan ide-ide mengenai media matematika. Aktivitas-aktivitas dalam pelatihan bertujuan agar guru memahami hal-hal penting yang diperlukan untuk dapat mengembangkan media matematika. Guru di ajak untuk merasakan bagaimana mudahnya belajar matematika dengan menggunakan media matematika yang sudah disiapkan narasumber. Setiap aktivitas diakui oleh guru mampu menginspirasi guru dalam mengembangkan media matematika. Contoh-contoh bagaimana membuat dan menggunakan media matematika yang diberikan sangat membantu guru-guru dalam menciptakan media matematika dengan memanfaatkan bahan dan alat sederhana. Namun guru-guru juga berharap adanya pelatihan lebih lanjut, baik terkait dengan media matematika maupun metode pembelajarannya.

Technology has significantly emerged in various fields, including healthcare, government, and education. In the education field, students of all ages and backgrounds turn to modern technologies for learning instead of traditional methods, especially under challenging courses such as mathematics. However, students face many problems in understanding mathematical concepts and understanding how to benefit from them in real-life. Therefore, it can be challenging to design scientific materials suitable for learning mathematics and clarifying their applications in life that meet the students’ preferences. To solve this issue, we designed and developed an interactive platform based on user experience to learn an advanced concept in the idea of linear algebra called Singular Value Decomposition (SVD) and its applicability in image compression. The proposed platform considered the common design principles to map between the provider in terms of clear mathematical explanation and the receiver in terms of matching good user experience. Twenty participants between the ages of 16 and 30 tested the proposed platform. The results showed that learning using it gives better results than learning traditionally in terms of the number of correct and incorrect actions, effectiveness, efficiency, and safety factors. Consequently, we can say that designing an interactive learning platform to explain an advanced mathematical concept and clarify its applications in real-life is preferable by considering and following the common design principles.

AbstractThis paper investigates and analyzes mathematics conceptions, mathematics learning and mathematical thinking of the first semester students from Electrical Engineering, Computer Engineering and Environmental Engineering courses of a private Higher Education institution, located in the city of Campo Grande, Mato Grosso do Sul, Brazil. This is a qualitative research conducted with the freshmen of the year 2018. In this research, questionnaires were used, together with interviews in the light of Oral History. For the analysis, two approaches were necessary: first looking into the narratives produced by the interviews and a second one with associated questionnaires. The questionnaire analyzes allowed us to identify, in general, manifestations of predominant cohesive mathematical conceptions, as well as, of speculative mathematical thinking. As for the comprehension associated with learning mathematics, the manifestations were equivalent. Regarding the students' mathematical concept of Analytical Geometry and Linear Algebra (AGLA), the concept of learning mathematics was the instrumental one, and so the mathematics concept proved to be cohesive with investigative and exact mathematical thinking. In the interviews, both the concepts that refer to mathematics and the AGLA discipline were the same. Concepts of relational mathematics learning, the concept of cohesive mathematics and speculative mathematical thinking were identified. Keywords:. Mathematics Conceptions.
