Abstract

Biplot analysis can be constructed from  an ordinary and robust Singular Value Decomposition (SVD) approach.  A SVD approach ordinary need data matrix that no outliers or extreme data.  If a outliers data is found in this research, ordinary SVD biplot will not able to assure the mapping illustration between observation object and variable. To solve this problem, approaching method to robust SVD is applied.  The couple of  ordinary and robust SVD’ eigenvalue couple and eigenvector have distance minimizing feature among data matrix and estimation matrix with  Euclid norm or L2 norm and city block distance or L1 norm.  Biplot analysis which is based on  robust SVD method can give illustrations to a outliers resist observation object and variable.  The boxplot of the achievement of TPB IPB show that the data has outliers.  Robust and ordinary SVD to data matrix based biplot analysis shows the data graph and structure is almost identic.  It implies that outliers has no effect to data structure alteration.  A couple of extreme datas are given to the data matrix and then anlysised using ordinary and robust SVD. Ordinary SVD biplot result is far more different from data matrix biplot without extreme data, in the other hand robust SVD biplot shows small data structure which means it is not influenced by extreme data..

Abstract

Ketika Technological Pedagogical and Content Knowledge (TPACK) secara fenomenal diakui sebagai kerangka kerja profesional guru, banyak para peneliti berlomba untuk mengkonseptualisasikan kerangka kerja tersebut berdasarkan pada disiplin ilmu. Hal ini menunjukkan bahwa TPACK merupakan kerangka kerja yang sifatnya terbuka untuk beragam pendekatan terutama dikaitkan dengan praktik pembelajaran. Dalam artikel ini, suatu meta-sintesis digunakan untuk menganalisis 8 buah jurnal dari 35 buah jurnal internasional pada rentang 2009-2022 yang dipandang relevan dan paling merepresentasikan keragaman dari konseptualisasi TPACK pada pembelajaran matematika. Pengumpulan data dilakukan dengan pendekatan meta-agregasi dimulai dari: memformulasikan pertanyaan penelitian, penelusuran literatur jurnal, analisis-sistesis temuan kualitatif, dan pengendalian mutu. Hasil penelitian menunjukkan bahwa TPACK dalam matematika (disebutkan sebagai Technological, Pedagogical, Mathematical Knowledge/TPMK) dikonseptualisasikan secara berbeda-beda berdasarkan karakteristik yang termuat pada pengetahuan dasar: TK (Technological Knowledge), CK (Content Knowledge)/MCK (Mathematical Content Knowledge), dan PK (Pedagogical Knowledge). Ketiga pengetahuan dasar ini tentu saja akan turut mempengaruhi konseptualisasi pengetahuan perantara: TPK (Technological Pedagogical Knowledge), TMK (Technological Mathematical Content Knowledge), PMK (Pedagogical Mathematical Content Knowledge), dan TPMK.

Abstract

This research aims to develop an effective learning design for understanding the concept of exponentiation by applying the Discovery Learning model using the Hypothetical Learning Trajectory (HLT) as the framework foundation. The research method used is a design research method consisting of three main stages: preliminary design, teaching experiment, and retrospective analysis. The initial stage involves literature analysis and the design of an HLT tailored to the concept of exponentiation. The instructional design is based on the prepared HLT and tested through two experimental stages: pilot experiment and teaching experiment. Retrospective analysis is conducted to compare the initial HLT with the Actual Learning Trajectory (ALT) achieved during the learning process. Data is collected through observation to monitor learning activities and environmental conditions, as well as through recordings of learning activities to gain an understanding of student participation in the design experiments. Additionally, Student Worksheets (SW) are used as aids for students to understand the concept of exponentiation, and evaluation questions are used to measure students' learning outcomes in the subject matter. Interviews are also conducted to gain a deeper understanding from the student's perspective. The results of this research make a significant contribution to the development of more effective mathematics learning methods, particularly in understanding the concept of exponentiation, and provide guidance for teachers to design learning that is more relevant to students' daily lives. The implications of the research results provide guidelines for teachers in designing learning that is more relevant to students' daily lives.

Abstract

To improve students' mathematical reasoning abilities, it is of course important to look at cognitive and affective aspects together, to see more broadly whether affective factors play an important role in mathematical reasoning abilities. This research aims to determine the differences in self-efficacy between male and female genders, differences in mathematical reasoning abilities between male and female genders, and the influence of self-efficacy on students' mathematical reasoning abilities in terms of gender. The research method used in this research is a correlational method with an ex post facto research design. The population of this study were all class VII students at SMP Negeri 20 Tasikmalaya. The sample in this research was obtained using non-probability sampling with a purposive sampling technique from the existing population. Classes VII-B, VII-C, VII-D, VII-E were selected as sample classes with a total of 102 students. The data collection technique is by giving a mathematical reasoning ability test and a self-efficacy questionnaire. The data analysis techniques used are descriptive statistical analysis, independent sample t-test, and two way ANOVA. Based on data processing, data analysis, and hypothesis testing, research results showed that (1) There are differences in self-efficacy between male and female genders, (2) There are no differences in students' mathematical reasoning abilities between male and female genders, (3) There is no influence of self-efficacy on students' mathematical reasoning abilities in terms of gender. These findings certainly show that affective aspects do have a role in determining students' abilities, but of course some affective aspects have a significant role, some only influence a small part.

Abstract

The importance of mathematical literacy skills is often not matched by the availability of supportive questions that aid in improving these abilities. Therefore, this study aims to develop valid and practical mathematical literacy questions specifically on the topic of circles, suitable for eighth-grade junior high school students. Employing the ADDIE model of research and development (RD), which includes analysis, design, development, implementation, and evaluation, the research involved 32 eighth-grade students as subjects. Instruments utilized included expert validation sheets, student response questionnaires, and a mathematical literacy test. Data analysis techniques encompassed both quantitative and qualitative analyses. Results from expert validation and student response questionnaires indicated that the developed instruments are both valid and practical. Expert validation tests achieved an 86% success rate overall, with 88% validity for material aspects, 88% for construction aspects, and 83% for language aspects. Validity testing, reliability testing, and item discrimination analysis confirmed the questions' validity, reliability, and appropriateness. The student response questionnaire yielded an 87% success rate, indicating high practicality for educational use. These findings demonstrate the effectiveness and applicability of the developed mathematical literacy questions in enhancing students' mathematical literacy skills and suggest their suitability for integration into the teaching process.
