Abstract

Tujuan penelitian adalah untuk mengetahui kemampuan literasi matematis siswa VIII yang diidentifikasi dari hasil tes pada materi sistem persamaan linear dua variabel (SPLDV). Identifikasi pecapaian kemampuan literasi matematis siwa didasarkan pada indikator yang dikembangkan dari definisi Stacey. Instrumen untuk mengambildata berupa tes dan pedoman wawancara. Jumlah subjek yang terlibat mengerjakan tes 20 siswa, dan diambil 3 sampel siswa secara cluster random sampling untuk diwawancarai. Sampel yang diwawancarai masing-masing mewakili kelompok siswa dengan kemampuan rendah (S1); sedang (S2), dan tinggi (S3). Data yang dikumpulkan dianalis sesuai tahapan dari Milles & Hubberman. Hasil analisis data menyimpulkan sampel (S1) tidak dapat mencapai indikator (N1), yaitu mampu memahami masalah; sampel (S2) dapat mencapai indikator (N2), yaitu dapat menggunakan konsep, fakta, dan prosedur dalam merumuskan langkah-langkah penyelsaian matematika, dan; sampel (S3) dapat mencapai indikator (N3), yaitu dapat menyajikan dan menyelesaikan masalah matematika.

Abstract

This study aims to analyze the achievement of students' mathematical literacy skills based on Stacey's definition. The achievement is measured using the answers to the basic linear function test results. The objectives are achieved using a descriptive qualitative approach. The indicators of achievement of mathematical literacy skills used are that students can: understand mathematical problems (I1); apply mathematical concepts (I2); use facts to formulate mathematical problems (I3), and; present and solve mathematical problems (I4). The subjects involved in the test consisted of 33 students, and then 3 students were selected by stratified random sampling to be interviewed, where each sample represents a group of students with high (S1), medium (S2), and low (S3) mathematical abilities. The instruments used to measure are test instruments and interview guidelines. The collected data were analyzed based on the Milles & Hubberman stages. The results of the data analysis concluded that students (S1) could achieve all indicators; students (S2) could not achieve the indicators of presenting and solving mathematical problems, and students (S3) could not achieve all the indicators set. Another finding is the existence of student self-confidence that affects their mathematical literacy skills

Abstract

The rapid development of science and technology necessitates fundamental transformations in education, particularly through learning innovations that accommodate diverse learning styles, enhance active student engagement, and stimulate intrinsic motivation in mathematics learning. This study aims to examine the effectiveness of the SAVI (Somatic, Auditory, Visual, Intellectual) learning model assisted by Macromedia Flash in improving geometry learning outcomes among eighth-grade students. The research employed a quasi-experimental pretest-posttest design with a control group. A total of 55 students were selected through cluster random sampling and divided into an experimental group (SAVI + Macromedia Flash) and a control group (conventional learning). Learning motivation was measured using a validated questionnaire and categorized into high, medium, and low levels. Macromedia Flash was chosen as a digital medium for its ability to visualize abstract geometric concepts interactively and attractively, thereby facilitating students' understanding of complex material. Data were analyzed using two-way ANOVA to assess the effects of the learning model, motivation level, and their interaction on geometry learning outcomes. The results showed that the SAVI model assisted by Macromedia Flash was significantly more effective in improving geometry learning outcomes than conventional methods (p < 0.05). However, no significant effects were found for motivation level or its interaction with the learning model on learning outcomes. These findings confirm that SAVI-based learning innovations integrated with digital multimedia can optimize geometry learning outcomes evenly, regardless of students' initial motivation levels. This study highlights the practical value of interactive, technology-based approaches in advancing mathematics education.
