This study aims to determine the effect of learning model on the mathematics learning outcomes of the students, knowing the influence of students' self-confidence in the results of learning mathematics. Furthermore, to determine the effect of learning models and students' self-confidence altogether to the result of learning mathematics. The research used is experimental method. The samples used from the affordable population taken from 34 people as the sample of the test instrument, and 68 people as the research sample using proportional random sampling technique from all grade X on SMA Negeri 3 Kabupaten Tangerang. The data were collected by giving the result of learning tests and questionnaires. The data analysis consists of testing the research instrument of validity, reliability, difficulty index, and distinguishing power*. Furthermore, there are the test of requirement analysis through normality and homogeneity test. The hypothesis tested by ANOVA 2 Lanes and Tukey. This study was conducted on February to May, 2017. Based on the results of the hypothesis and data analysis, it is concluded that the following things are: 1) There is an influence between the learning model on the learning outcomes of mathematics. 2) There is an influence between students' self-confidence on mathematics learning outcomes. 3) There is an interaction effect between learning methods and students' self-confidence on mathematics learning outcomes.

This study aims to identify the factor structure of students’ algebraic thinking skills within an area model learning context supported by PhET Interactive Simulation. A quantitative approach using exploratory factor analysis was applied to data from 128 students based on 16 indicators representing four aspects of algebraic thinking: generalization, representation, transformation, and conceptual meaning. The analysis involved the Kaiser-Meyer-Olkin (KMO) test, Bartlett’s test of sphericity, measures of sampling adequacy (MSA), principal component analysis, eigenvalue criteria, and Varimax rotation. The initial analysis produced a KMO value of .631, while four variables (G1, G3, G4, and R1) were removed because their MSA values were below .50. The analysis of the remaining 12 variables produced a KMO value of .689 and a significant Bartlett’s test (p < .001). Four components with eigenvalues greater than 1 were retained and accounted for 62.06% of the total variance before rotation. The rotated solution revealed three interpretable dimensions: a visual-representational factor integrating generalization and representation, a procedural-transformational factor, and a conceptual-meaning factor. The fourth component had no clearly dominant group of indicators and was therefore interpreted cautiously as a residual component. These findings indicate that students’ algebraic thinking in the examined instructional context is multidimensional, with visual-representational, procedural-transformational, and conceptual dimensions showing distinct patterns.

Kurangnya kemampuan berpikir visual matematis pada mahasiswa dapat menghambat pemahaman konsep fungsi kuadrat secara mendalam. Penelitian ini bertujuan untuk mengatasi masalah tersebut dengan mengevaluasi efektivitas worksheet graphing quadratics dalam meningkatkan kemampuan berpikir visual matematis mahasiswa. Metode penelitian yang digunakan adalah Single Subject Research (SSR), yang berfokus pada perubahan performa individu dalam kondisi baseline dan intervensi. Partisipan terdiri dari tiga mahasiswa tingkat pertama program studi pendidikan matematika di Universitas Serang Raya. Data kinerja mahasiswa dikumpulkan melalui tiga sesi pada fase baseline dan lima sesi pada fase intervensi. Teknik analisis data yang digunakan adalah analisis regresi linier untuk mengukur perbedaan signifikan antara fase baseline dan intervensi. Hasil penelitian menunjukkan peningkatan yang signifikan dalam performa setiap subjek selama fase intervensi, dengan adanya peningkatan level, kecenderungan perubahan yang kuat, dan perubahan segera setelah intervensi dimulai. Temuan ini menunjukkan bahwa penggunaan worksheet graphing quadratics efektif dalam mengoptimalkan kemampuan visualisasi matematis mahasiswa. The limited visual mathematical thinking abilities of students can hinder a deep understanding of quadratic functions. This study aims to address this issue by evaluating the effectiveness of graphing quadratics worksheets in enhancing students' visual mathematical thinking. The research employs a Single Subject Research (SSR) method, focusing on individual performance changes across baseline and intervention phases. Three first-year students from the mathematics education program at Universitas Serang Raya participated in the study. Performance data were collected over three sessions in the baseline phase and five sessions in the intervention phase. Linear regression analysis was used to assess significant differences between baseline and intervention phases. The results indicated a significant improvement in each subject's performance during the intervention, with an increase in level, a strong trend, and immediate change upon the intervention’s onset. These findings suggest that graphing quadratics worksheets effectively optimize students' mathematical visualization skills.
