Abstract

The technology era provides new opportunities to improve mathematics teaching and learning. In this paper, we reported the implementation of Adobe Flash as learning media for improving students' reasoning ability. Results suggested a significantly improved reasoning ability in experimental class compared to control class, which indicated the effectiveness of Adobe Flash as media for learning geometry. The use of animation, video, and worked example, foster students’ reasoning ability by making geometrical concepts transparent and reducing possible misleading spatial perception.

Abstract

This research is motivated by the low mathematical representation skills of students. This is evidenced by the mathematics learning achievement of Indonesian students in TIMSS and PISA which has not moved from the bottom 10 ranks. In learning mathematics, there are still some obstacles, including students who are still difficult to read mathematical expressions, errors in principles and procedures, not being able to connect one concept to another and difficulty communicating mathematical ideas / ideas. Mathematics learning based on android applications is an alternative idea that can be a solution to the problems above. This study aims to examine: (1) How is the application of Android-based mathematics learning (2) How is the process of mathematical representation and student responses in the application of Android-based mathematics learning. (3) How to anticipate learning that must be perfected to optimize student representation skills. This research method uses qualitative methods using instruments in the form of teacher observation sheets, student observation sheets, interview sheets and student understanding tests.Penelitian ini dilatarbelakangi oleh masih rendahnya keterampilan representasi matematis siswa. Hal ini dibuktikan dengan prestasi belajar matematika siswa Indonesia pada TIMSS dan PISA masih belum beranjak dari 10  peringkat terbawah. Di dalam pembelajaran matematika, masih ditemukan beberapa kendala diantaranya siswa masih sulit membaca ekspresi matematika, kesalahan prinsip dan prosedur, belum mampu menghubungkan antara satu konsep dengan konsep lainnya serta kesulitan dalam mengkomunikasikan gagasan/ide matematika. Pembelajaran matematika berbasis aplikasi android adalah salah satu gagasan alternatif yang dapat menjadi solusi permasalahan diatas. Penelitian ini bertujuan untuk mengkaji : (1) Bagaimanakah penerapan pembelajaran matematika berbasis Android(2) Bagaimanakah proses representasi matematis dan respon siswa dalam penerapan pembelajaran matematika berbasis Android. (3) Bagaimana antisipasi pembelajaran yang harus disempurnakan untuk mengoptimalkan keterampilan representasi siswa. Metode penelitian ini menggunakan metode kualitatif dengan menggunakan instrumen berupa lembar observasi guru, lembar observasi siswa, lembar wawancara dan tes pemahaman siswa.

Abstract

The relationship between spatial conceptions and students' spatial abilities is still rarely studied specifically, even though this is the basis for students to think in learning geometry. This paper aims to explore spatial abilities and the development of spatial ability theory, discusses the relationship between spatial conceptions in students' understanding, and how to develop HLT (Hypothetical Learning Trajectory)in transformation geometry learning. HLT design consists of three stages: initial design, experimental, and retrospective analysis. The results of HLT are then refined into LIT (Local Instructional Trajectory). Then this paper present the empirical results of the perceptions of twenty  9th grade students in one of Islamic private school in Kabupaten Kuningan, West Java, Indonesia, towards the corresponding geometric and math questions. Literature review analysis was used to analyze the retrieved articles. At the end of the paper, we explain and discuss how to apply mathematical conceptions in learning geometry. This research is expected to be a guidance for teachers to develop learning in accordance with the students' spatial thinking process in studying geometry.

Abstract

The 21st-century era, marked by the rapid development of information technology, requires students to be adaptive and have several skills that must be mastered to be able to compete in today's era. The important skills in the 21st century or so-called The 4C-skills consist of communication, collaboration, critical thinking, in general containing specific skills that need to be empowered in learning activities, such as problem-solving skills, critical thinking, communication skills, collaborating, innovation and creation, literacy, information metacognition, and various other skills. However, the reality in the field is based on the results of TIMSS and PISA, where this test measures the mathematics, science, and literacy skills of developed and developing countries, Indonesia's ranking is still in the lowest rank. The method used in this research is the literature study method, which examines the STEM principles, implementation strategies, and their prospects for improving scientific literacy skills. Based on the results, the success key while implementing STEM in the classroom is to prepare STEM educators with a conceptual understanding of the principles, frameworks, and strategies of integrated STEM implementation and learning theories from the four STEM fields. It should be integrated to increase the pedagogical skills and to mastery the technology as a learning support. Also, the development of professional experience for teachers in implementing STEM in various cross-materials is needed to provide a strong conceptual framework of an integrated STEM approach and build their confidence in teaching an integrated STEM approach. Hopefully, this article can provide a comprehensive overview of improving scientific literacy as one of the keys to improving the quality of quality education in Indonesia.
