Abstract

Tax policy was crucial as it influenced economic growth. The tax rate was determined by the income level of the population. To improve tax administration quality, the government developed infrastructure and enhanced the services of tax office employees. By gathering taxpayers' opinions, the quality of services and oversight could be analyzed to refine tax administration performance in the future. This study aimed to determine the effect of service quality, consultation, and supervision by account representatives on taxpayer compliance. It employed a quantitative approach, utilizing various statistical tests with SEM analysis. The population consisted of 97,714 active taxpayers registered at six KPP Pratama offices in Lampung in 2022. The sample size was determined using the Slovin formula, resulting in 100 taxpayers selected through Simple Random Sampling. Data were collected directly from active taxpayers using a questionnaire as the research instrument. The findings revealed that the variables of service quality, consultation, and supervision by account representatives had a significant influence on taxpayer compliance, both partially and simultaneously.

Abstract

This study aims to determine whether there is an effect of the SSCS learning model with a metaphorical approach and PBL learning on mathematical problem-solving abilities in terms of learning styles. This research is a type of Quasy Experiment Design. The population in this study were students of class VIII at SMP N 09 Tulang Bawang Tengah, the sampling method used a simple random sampling technique. The data in this study were collected using tests and questionnaires. Hypothesis testing using analysis of variance of two unequal cells with a significance level of 5%. The prerequisite tests in this study include the normality test and the homogeneity test using SPSS which were carried out before testing the hypothesis. The results of the analysis obtained that p-value (sig.) = 0.037 0.05 then H0 was rejected, p-value (sig.) = 0.035 0.05 then H_0 was rejected, p-value (sig.) = 0.732 0, 05 then H0 is accepted so that, the results of the analysis in this study are (1) there is an effect of the SSCS learning model with a metaphorical approach and PBL model learning on mathematical problem-solving abilities. (2) there is an effect of visual, audio, and kinesthetic learning styles on mathematical problem-solving abilities. (3) there is no interaction between learning model factors and learning styles on mathematical problem-solving abilities.

Abstract

Mathematical problem-solving ability is an essential skill for prospective teachers; however, many students still face difficulties, particularly in proof-based problems. Previous studies have mostly examined personality types in the context of application-based tasks, so there has been limited attention to students’ mathematical problem-solving abilities with the artisan personality type in dealing with proofs of statements. UIN Madura students in the Mathematics Education study program tend to have an artisan personality. They have a tendency to solve problems by using a common pattern. Therefore, when they faced mathematical proof comprehension problems, they often experienced difficulties and limitations. This made the researcher interested in conducting a study that aims to describe the abilities of UIN Madura students in the Mathematics Education study program in solving mathematical problems based on Polya's theory viewed from the artisan personality type. This study is a descriptive qualitative study. The subjects of this study were two students with the artisan personality type. Data collection instruments used questionnaires (personality type data), essay tests (problem-solving abilities), and interviews. Data analysis techniques used the Miles and Huberman technique. Based on the research results, it is known that artisan-type students can understand problems, make plans, and solve problems correctly but cannot re-check the results they have obtained. This indicates the tendency of artisan-type students to choose quick and simple approaches, yet with less accuracy in the verification process. This study contributes to the scientific development by highlighting the distinctive characteristics of artisan-type students in solving mathematical proofs. The findings of this research can serve as a basis for educators in designing learning strategies that are more aligned with students’ personalities.

Abstract

Modern mathematics education must shift from merely "knowing" mathematics to "doing" mathematics. This "doing" process inherently demands strong problem-solving skills, which can only flourish in students who have internalized Habits of Mind as part of their intellectual character. In this study, we report on the effect of a flipped classroom learning model, assisted by the eXe-Learning application, on the mathematical problem-solving abilities of students with high, moderate, and low categories of Habits of Mind. This study employed a quantitative method with a quasi-experimental design. The sampling technique used was cluster random sampling, with classes serving as the clusters. Research data were collected using two types of instruments: test and questionnaires. The data were analyzed using a two-way ANOVA with unequal cell sizes, preceded by prerequisite tests for normality and homogeneity. Based on the analysis, it can be concluded that the flipped classroom model assisted by the eXe-Learning application has a significant effect on both students' mathematical problem-solving abilities and their Habits of Mind. However, the interaction between the flipped classroom model and students' Habits of Mind did not have a significant effect on their mathematical problem-solving abilities. Keywords: Flipped classroom; problem-solving skills; exe-learning; habits of mind
