Abstract

This research is motivated by students' low mathematical communication skills. Students have difficulty in solving questions related to mathematical communication. One reason is learning that only uses conventional learning models, so students' creativity and activity are still less visible. The purpose of this study was to find out and describe mathematical communication skills taught by problem based learning learning methods better than those taught with conventional learning models with expository methods. This type of research is a Quantitative Approach with quasi experimental methods. The sample of the study amounted to 67 students, 33 students in the experimental class and 34 students in the control class obtained by the Simple Random Sampling technique. The technique of collecting data through a test of mathematical communication skills in the form of a description sheet (Essay) consisting of 8 questions. The data analysis technique uses the t-test. The results revealed that the results of the average experimental class score were higher than the results of the average score of the mathematical communication skills of the control class students. Thus the problem based learning learning method influences students' mathematical communication skills ( . The conclusion of this study is that mathematical communication skills of students who use problem based learning learning methods are better than students' mathematical communication skills using conventional learning, meaning learning methods of problem based learning provide an influence on mathematical communication skills. Keywords: Basec Learning Problem and Mathematical Communication Skills.

Abstract

The purpose of this study is to produce learning devices and LKS based on a realistic, valid and effective approach to realistic mathematics education. This learning tool is expected to be able to improve student learning activities and outcomes. This type of research is development research using a 4-D model consisting of 4 stages, namely 1) defining, 2) designing (design), 3) developing, and 4) disseminating (disseminate). The contextual mathematics learning tools developed are Student Worksheets (LKS) and Learning Implementation Plans (RPP). Validation is done by experts in mathematics education, basic education and language. The practicality of learning devices is investigated by observing the implementation of learning, filling the practical questionnaire by students, and conducting interviews with students and teachers. To see its effectiveness is done by observing the activities and student learning outcomes. The collected data was analyzed descriptively.

Abstract

This research is motivated by the lack of student learning discipline in participating in learning such as students arriving late to school, being late in collecting assignments, not paying attention when the teacher explains the subject matter. The purpose of this study was to determine and describe the significant influence between learning discipline and mathematics learning outcomes. This study uses a quantitative approach with a correlational method. The population in this study were all students of class XI SMA Negeri 17 Merangin which consisted of 2 classes with a total of 41 students. The sampling technique in this research is total sampling where the entire population is used as the research sample. Data collection techniques in this study were questionnaires and tests. The instrument used is in the form of statement items and learning outcomes test items. The analytical technique used to test the hypothesis is Product Moment Correlation. for the significance test using the Z-test, followed by the determinant coefficient formula to state the size of the contribution of the X variable to the Y variable. Then, a simple linear regression test and a regression significance test were carried out. Based on the results of data analysis, it shows that Fcount > Ftable or 6,718 > 2.108, then H0 is rejected and H1 is accepted, meaning that there is a significant influence between learning discipline on mathematics learning outcomes for class XI students of SMA Negeri 17 Merangin for the 2020/2021 academic year, with a contribution of 14, 67%.

Abstract

The purpose of this research is to obtain empirical evidence on these factors are the variables of commisioner independent, committe audit, profitability, leverage, company size, sales growth and tax avoidance. The population of this research is all manufacturing companies listed on the Indonesia Stock Exchange (IDX) during 2018 to 2020. There were 168 manufacturing companies that are listed from 2018 to 2020. Samples are obtained through purposive sampling method. The sample taken for this research is 70 companies, so that the total data used as the research sample was 210. The analysis method used in this research is multiple regression.This results of this research that profitability and leverage have a significant influence on tax avoidance. Meanwhile, commisioner independent, audit committee, company size, sales growth has no effect on tax avoidance. Profitability has an effect on tax avoidance because if the company has a high profit, the company will try to reduce tax expense by tax avoidance, so that the profit earned by the company can still be maximized. The results of this study are in line with agency theory which states that managers have the hope of being able to increase profits or high company profitability because of the benefits obtained, namely getting compensation from the principal (company owner). The principal does not want the company to do tax avoidance, but the manager wants to do it to keep getting optimal profit so that the manager can get compensation from the principal. Leverage has an effect on tax avoidance because the increasing level of corporate debt will increase the amount of debt from third parties, with an increase in the amount of debt it will increase interest costs and will make the tax expense paid decreases. So that the use of debt by the company can be used for tax savings by obtaining incentives in the form of interest expense which will be a deduction from taxable income. The results of this study are in line with the trade off theory which states that if a company uses debt as its financial funding, it will provide benefits to reduce the company’s tax costs, because according to the company, debt has a fixed burden, namely interest costs. Interest costs are part of the burden that reduces the company’s taxable income (deductible expense) so that using debt will provide a positive relationship with tax avoidance actions taken by the company.

This research model uses a 4-D model which consists of four stages, namely: the definition stage (Devine), the design stage (Design), the development stage (Develop) and the dissemination stage (Disseminate). LKPD which has been validated by five experts. Validity is seen from the results of the validation sheet, while practicality is seen from the practicality questionnaire sheet of student responses, while the effectiveness of learning outcomes and student learning activities. The results of the analysis at the validation stage showed that the average score of the validation results from the material experts was 4.33, the validation from the linguists was 4.60 and the validation from the media experts was 4.94, so the results of all validations obtained an averageof 4.62 with very valid criteria. The results of the practicality questionnaire analysis show that the practicality of scientific-based worksheets produced is practical with a percentage of 96.70% and the percentage of completeness of classical learning outcomes of 78.6%. Based on the results of the study, it was found that the LKPD developed was valid, practical, and effective
