Abstract

This research is a correlation study with a quantitative approach. The data collection techniques used in this study were questionnaire techniques and documentation methods. The population and sample in this study were students of Class VIII SMP Negeri 43 Merangin. The data analysis technique used is the Normality Test, Linearity, and Hypothesis Test. Based on the results of the analysis with the product moment correlation, it shows that there is a relationship between learning motivation and learning outcomes in Mathematics for class VIII grade SMP Negeri 43 Merangin. This is indicated by the magnitude of the r count value is greater than the r table (0.6430> 0.413) and a significance value of 0.000 which means less than 0.05 (0.000 <0.05), so this study succeeded in proving the hypothesis which states that "There is a positive relationship. and significant learning motivation with the learning outcomes of class VIII class of SMP Negeri 43 Merangin Mathematics, and the value of the coefficient of determination is calculated by the formula kd r2 x 100% so that learning motivation affects the learning outcomes of grade VIII students of SMP Negeri 43 Merangin by about 41.35%. And the rest is influenced by other factors.

Abstract

This study aims to determine and describe the mathematical problem solving abilities of students taught by using the learning model the power of two is better than conventional learning. The study used a quantitative approach with the experimental method. The study population was all IX grade students of Subulussalam MTs which numbered three classes with samples of class IX A as the experimental class and class IX C as the control class. The instruments used are test questions for esay mathematical problem solving abilities. The results of the data analysis requirements indicate that the data of the two sample classes are normally distributed and have homogeneous variances. Hypothesis testing uses the t-test formula. Based on the results of the analysis of research data shows that t count is greater than t table or 1.84 > 1.68 in the one-party test. Because t count > t table then Ho is rejected and Ha is accepted, so it can be concluded that the mathematical problem solving ability of the power of two learning model is better than conventional learning of IX grade students of MTs Subulussalam.

Abstract

This research started from the low mathematical ability of students, namely the ability to understand mathematical concepts. This can be seen in the daily scores of the fifth grade students of MIS Nurul Ijitihad, Lubuk Gaung Village, Merangin Regency which is under the Minimum Completeness Criteria (KKM), so that mathematics learning has not been running as expected. This study aims to describe the process of improving students' mathematical concept understanding skills through the Realistic Mathematical Education approach to fifth grade students of Madrasah Nurul Ijtihad Swasta, Lubuk Gaung Village, Kab. Merangin. The research subjects were students of Madrasah Nurul Ijtihad Private, Lubuk Gaung Village, Kab. Merangin which amounted to 19 people. The type of research used is classroom action research. This research uses a qualitative approach which is supported by a quantitative approach. Qualitative data obtained through observation of student activities.Quantitative data was obtained through a test of the ability to understand mathematical concepts which was carried out at the end of each lesson in cycle I and cycle II. Quantitative data analysis technique with percentage formula. The data obtained are presented in tabular form. The results show that the Realistic Mathematical Education approach can improve the ability to understand mathematical concepts of fifth grade students of Madrasah Nurul Ijtihad Swasta, Lubuk Gaung Village, Kab. Merangin. This increase can be seen from the average test results of students' mathematical concept understanding ability in cycle I and cycle II. In the first cycle, the average value of the students' mathematical concept understanding ability test was 69.16 in the sufficient category. In the second cycle the average test score of 82.63 students was categorized as very good. The percentage increase in the average score of students from the first cycle is 13.47%
