Abstract

This study aims to describe whether or not mastery of trigonometry affects students' ability to solve geometric problems in class X at SMAN Kadugede. The form of research used in this study is a quantitative research method. The research design used in this study is a one-shot case study, meaning that the treatment is applied to one experimental group, and then the dependent variable is measured. This design aims to determine a variable's effect on other variables effectively. The data collection instrument used was a test of mastery of trigonometric material and students' abilities in solving three-dimensional space problems. The population in this study was 253 students of class X; in this study, the authors took samples using the cluster random sampling technique with the object sampled in this study, namely class X 4, as many as 34 students at SMA Negeri 1 Kadugede. Analysis of the research data using linear regression test. Mastery of trigonometry material significantly influences mastery of three-dimensional space material. This is indicated by a significant value of 0.000 < 0.05 and the regression equation obtained is Y = 11.435 + 0.758 . The equation means that the ability to solve geometrical problems increases or increases by 0.758 times the mastery of trigonometry material, while the constant value of 11.435 states that if students do not have mastery of trigonometry material, then the ability to solve three-dimensional space problems is shallow. The results of the statistical test showed that there was an effect of mastery of trigonometry material on students' ability to solve three-dimensional problems.

Abstract

The Qur'an is the holy book of Muslims, encompassing not only guidance for faith but also various fields of knowledge, including mathematics. One of the relevant branches of mathematics is algebra, which serves as an analytical tool to understand religious commands, particularly in the management of infaq. This study aims to analyze the connection between algebraic concepts and Qur'anic verses related to infaq using a literature review approach. The lack of prior research integrating algebra and verses on infaq motivated this study. The findings identify six algebraic concepts applicable to the calculation, management, and distribution of infaq, supported by Qur'anic verses, tafsir, and empirical data from institutions such as BAZNAS. The study focuses on variables, coefficients, and constants in algebra and their application to obligatory and voluntary infaq. The analysis demonstrates that algebraic concepts can simplify calculations and facilitate infaq management while reinforcing the link between science and Islamic values. This research contributes to motivating individuals to give infaq by understanding its essence and the remarkable rewards described in the Qur'an. The findings also offer new insights into the utilization of algebra to support a more systematic and practical management of infaq in the modern era. Al-Qur’an merupakan kitab suci umat Islam yang tidak hanya mengandung petunjuk keimanan, tetapi juga berbagai ilmu pengetahuan, termasuk matematika. Salah satu cabang matematika yang relevan adalah aljabar, yang dapat berfungsi sebagai alat analisis untuk memahami perintah syariat, khususnya dalam pengelolaan infak. Penelitian ini bertujuan menganalisis keterkaitan antara konsep aljabar dengan ayat-ayat Al-Qur’an tentang infak melalui pendekatan kajian pustaka. Kurangnya penelitian sebelumnya yang mengintegrasikan aljabar dan ayat tentang infak mendorong dilakukannya kajian ini. Hasil penelitian mengidentifikasi enam konsep aljabar yang dapat digunakan untuk menghitung, mengelola, dan mendistribusikan infak, dengan dukungan ayat Al-Qur’an, tafsir, serta data empiris dari BAZNAS. Fokus penelitian mencakup variabel, koefisien, dan konstanta dalam aljabar, serta penerapannya pada infak wajib dan sunnah. Analisis menunjukkan bahwa konsep aljabar mampu menyederhanakan perhitungan dan mempermudah pengelolaan infak, sekaligus menguatkan hubungan antara ilmu pengetahuan dan nilai-nilai keislaman. Penelitian ini memberikan kontribusi dalam memotivasi masyarakat untuk berinfak dengan memahami esensi dan ganjaran luar biasa yang dijelaskan dalam Al-Qur’an. Temuan ini juga membuka wawasan baru tentang pemanfaatan aljabar untuk mendukung pengelolaan infak secara lebih sistematis dan aplikatif di era modern.

Abstract

Abstract This research aims to analyze the impact of implementing assessments that do not consider differences in student learning styles in mathematics learning. The method used is an experiment with a quasi-experimental design. Students in two different class groups were randomly selected. The experimental group received an assessment that took learning style into account, while the control group received an assessment without considering this. The results of data analysis show that the learning outcomes of students who do not receive learning style-based assessments are not as optimal as those of students who receive learning style-based assessments (p < 0.05). These findings highlight the importance of considering students' learning styles in the assessment process to improve the effectiveness of mathematics learning. Analysis of questionnaires related to student perceptions of learning style-based assessments shows varying results. The overall indicator scores show variation in students' perceptions of mathematics assessments, with a fairly wide range of scores. Most students feel motivated to learn by implementing learning style-based assessments in mathematics assessments. However, some students experience limitations in developing their potential with learning style-based assessments. These findings provide valuable insight into diverse student perspectives on the use of learning style-based assessments in mathematics learning contexts.

Abstract

The aim of this research is to determine the content validity, construct validity, reliability, difficulty level, discriminating power, and the effectiveness of distractors of the weekly test questions for SMPN 1 Astanajapura. These questions were independently created by the teachers of SMPN 1 Astanajapura and have not been previously tested or analyzed. The population or subjects of this study are ninth-grade students, selected using purposive sampling, meaning not all ninth-grade students were used as samples, only 3 out of 8 classes were chosen as samples. Data collection in this research employed documentation and interview methods. The analysis results show good content validity and construct validity. The reliability value is 0.88 with a confidence level of 0.60. The distribution proportion of difficulty levels is easy and moderate, with 70% being easy and 30% moderate. As for the discriminating power of the questions, 70% were categorized as sufficient, and 30% as good. The effectiveness of the distractors needs improvement to be used effectively.

Abstract

In the context of 21st-century education, numeracy literacy is a crucial competency that supports students’ critical thinking and problemsolving abilities across various disciplines. However, many students continue to struggle with applying mathematical concepts in real life situations. This study aims to explore the role of formative assessment in enhancing students' numeracy literacy in secondary school settings. Utilizing a qualitative approach, data were collected through classroom observations, semi-structured interviews with teachers and students, and documentation analysis. The participants consisted of three mathematics teachers and twelve students from different grade levels in a public secondary school. Thematic analysis was employed to identify key patterns in the data. The findings reveal that formative assessment strategies such as real-time feedback, reflective questioning, and peer assessment significantly contributed to the development of students’ numeracy skills. Teachers reported improved student engagement and better diagnostic understanding of learning gaps, while students demonstrated increased confidence and ability to apply mathematical reasoning. The study concludes that formative assessment is an effective pedagogical tool for supporting numeracy literacy and recommends its integration into daily classroom practices to foster a deeper understanding of mathematical concepts.
