Abstract

Kemampuan pemahaman konsep sangat dibutuhkan dalam proses pembelajaran matematika yang harus dikuasai untuk menunjang keberhasilan proses pembelajaran. Penelitian kuantitatif ini mengkaji kemampuan pemahaman konsep matematis siswa dengan mengimplementasikan model VARK-Fleming dan self-concept sebagai variabel kovariat. Penelitian ini bertujuan untuk mengetahui pengaruh model VARK-Fleming terhadap kemampuan pemahaman konsep matematis dengan mengontrol self-concept siswa dan pengaruh variabel kovariat self-concept terhadap kemampuan pemahaman konsep matematis siswa, serta pengaruh secara simultan model VARK-Fleming dan self-concept terhadap kemampuan pemahaman konsep matematis siswa. Partisipan dalam penelitian ini berjumlah 64 siswa SMP, dengan rincian 32 siswa belajar menggunakan model VARK-Fleming dan 32 siswa belajar dengan model ekspositori. Alat yang digunakan untuk mengumpulkan data adalah angket dan tes uraian. Pengujian hipotesis menggunakan analysis of covariance (one-way ancova). Hasil penelitian ini menunjukkan bahwa terdapat pengaruh lebih baik model pembelajaran VARK-Fleming dibandingkan model ekspositori dan self-concept terhadap kemampuan pemahaman konsep matematis siswa baik secara parsial maupun simultan. Concept understanding is required for the learning process to be successful. This quantitative study investigates students' mathematical concept understanding abilities using the VARK-Fleming model and self-concept as a covariate variable. The purpose of this research is to determine the effect of the VARK-Fleming model on students' ability to understand mathematical concepts by controlling for students' self-concept and the effect of the covariate variable of self-concept on students' ability to understand mathematical concepts, as well as the simultaneous concept of the VARK-Fleming model and self-concept on students' ability to understand mathematical concepts. Sixty-four junior high school students participated in this research, with 32 learning the VARK-Fleming model and 32 learning the expository model. Questionnaires and descriptive tests were employed to collect information. The analysis of covariance was utilized for hypothesis testing (one-way ANCOVA). The findings of this research reveal that the VARK-Fleming learning model has a better effect on students' mathematical concept understanding capacity than the expository model and self-concept, both partially and concurrently.

Abstract

This reseacrh aims to examine whether students' perceptions of teacher performance have a positive influence on their mathematical problem-solving abilities. The research subjects consisted of 30 tenth-grade students from SMKN 3 Bandar Lampung. The research methodology employed is a quantitative approach with data analysis techniques, including regression analysis, within the framework of an ex-post facto study. The research instruments include a problem-solving ability test comprising four items that have undergone validity testing, reliability testing, difficulty level testing, and discrimination power testing. Additionally, a student perception questionnaire regarding teacher performance was utilized, consisting of 25 statement scales adopted from Suryanti (2021) with indicators such as teaching style, ability to interact with students, and personal characteristics. The findings indicate that students' perceptions of teacher performance do not significantly influence their mathematical problem-solving abilities. There is a possibility of other factors, such as family support, learning environment, or teaching methods, not accounted for in this study. Each student responds uniquely to mathematical challenges, suggesting that the influence of teacher performance may vary among individuals and requires further consideration. The results highlight the significance of other elements beyond teacher performance in developing students' mathematical problem-solving abilities. Educators and researchers can explore these factors for a more comprehensive understanding, taking into account the relevance of the findings in specific learning contexts and student characteristics. Although no significant influence was detected, practical implications include efforts to enhance other factors supporting students' mathematical abilities, such as the development of additional teaching strategies or increased support outside the classroom.

Abstract

This research aims to examine the influence of self-confidence on students' mathematical critical thinking abilities. The study involved 27 students from class VIII A at SMPN 4 Bandar Lampung. The method employed in this research was a quantitative approach using data analysis techniques such as regression analysis and characterized as an ex-post facto study. The research instruments included a test of critical thinking abilities consisting of 8 items that underwent processes of validity testing, reliability testing, difficulty level assessment, and discriminant power testing. Additionally, there was a student perception questionnaire regarding teacher performance consisting of 25 statement scales adopted from Febriandari Siwi (2021) with indicators: a) Confidence in one's abilities; b) Independence, responsibility, and desire for high achievement; c) Persistence; d) Willingness to take action. The findings of this study indicate that self-confidence does not have a significant influence on students' mathematical critical thinking abilities. There might be other factors, such as family support, learning motivation, or teaching methods, which were not encompassed in this research. Each student responds uniquely to mathematical challenges, hence the impact of teacher performance may vary among individuals and necessitates further consideration. The results suggest that factors beyond self-confidence play a crucial role in developing students' mathematical critical thinking skills. Educators and researchers can further explore these factors for a more comprehensive understanding, considering the relevance of outcomes within specific learning contexts and student characteristics. Despite the absence of a detected significant influence, practical implications include efforts to enhance other factors supporting students' mathematical abilities, such as developing additional teaching strategies or improving family support and environmental factors outside the classroom

Abstract

Background: Statistical data from Lampung Province indicate a steady annual increase in the number of taxpayers utilizing e-SPT (electronic tax return) and e-filing, particularly from 2019 to 2022.Aim: This study aims to analyze the effect of e-SPT usage on taxpayer compliance, investigate the impact of e-filing on taxpayer compliance, assess the combined effects of e-SPT and e-filing on taxpayer compliance, and understand taxpayer compliance within the framework of Islamic Economics.Method: Taxpayers from the Bandar Lampung Tax Office (KPP) were selected as respondents. A random sampling technique was employed to gather data from 100 participants. The data were analyzed using multiple linear regression analysis with SPSS.Results: The findings reveal that the convenience, effectiveness, and satisfaction derived from using e-SPT and e-filing, along with an analysis of Annual Tax Returns, significantly influence taxpayer compliance. The use of e-SPT alone has a notable impact on compliance, as does the use of e-filing. Furthermore, the combined usage of e-SPT and e-filing has a significant collective impact on taxpayer compliance.Conclusion: The study concludes that both e-SPT and e-filing are critical in enhancing taxpayer compliance, with their combined application having a more substantial effect. These findings also offer insights into taxpayer compliance from the perspective of Islamic Economics, emphasizing the role of modern tax administration tools in promoting compliance.
