The Influence of Realistic Mathematical Approach to Understanding Concept and the Mathematical Connection Ability of Islamic Private Vocational School Students Hikmatul Fadhillah Medan Class VII

Abstract

The purpose of this research in the design of Quasi Experiment is to investigate the effect of the Realistic Mathematical Approach (PMR) on the ability to understand students' mathematical concepts, the ability of students' mathematical connections and the interaction between learning approaches with students' initial abilities on the differences in the influence of students' understanding abilities and students' mathematical connections. The research was carried out at Hikmatul Fadhillah Islamic Private Middle School in class VII with 118 students. This research is an experimental study with a test-post-test control group design research design. The population in this study were all students of class VII by taking a sample of two classes (experimental class and control class) through random sampling techniques. Data obtained through KAM test, mathematics concept comprehension ability test, and mathematics connection ability test. Data were analyzed by two-way ANAVA test. Before using the two-way ANAVA test homogeneity tests were used in the study and normality in this study was 5% significant. The results of data analysis showed that the average concept comprehension ability test was 71.43 and the control class was 62.54, with a value of sig = 0 with 0 <5 0.05, so there was a difference in the effect of students' understanding of mathematics concepts being taught with a mathematical approach realistic mathematics (PMR) with the usual learning approach, the average test ability of experimental and control mathematical connections is 70.43 and 67.76 with sig = 0, with 0 <∝ 0.05, then there are differences in the effect of students' mathematical connection abilities taught with a realistic mathematics approach (PMR) and conventional learning approach, a significant value of 0.127, because 0.127> 0.05

The Effectiveness of Using Mathematics Books in Islamic Studies for Students of Tadris Mathematics Study Program

“…Mathematics books in Islamic studies are also focused on mastering mathematical material based on the Qur'an. Mastery of concepts is very important to be implanted in students' understanding [9]. Understanding mathematical concepts is very important because mastery of concepts will facilitate students in learning mathematics.…”

Influence of Problem Based Learning Modelsand Gender to Ability Student Mathematic Communication

“…According to Adliani (2020) in each learning effort is emphasized more on mastery of concepts so that students have a good basic stock to achieve other basic abilities such as reasoning, communication, connection and problem solving.Often experiences difficulty in changing learning habits from initially learning by listening, recording and memorizing information conveyed by the teacher, to learning by searching for data, analyzing, constructing hypotheses, and solving them themselves.…”

The Development of Local Culture Based Teaching Materials with Constructivism Approach to Improve the Thinking Ability and Mathematics Disposition of Student

“…Wardani (2008: 15) suggests that mathematical disposition is an interest and appreciation of mathematics, namely the tendency to think and act positively, including selfconfidence, curiosity, persistence, enthusiasm for learning, persistence in facing problems, flexible, willing to share with others, reflective in mathematical activities (doing math). According to (Adliani, 2020) students have difficulty in solving problems understanding mathematical concepts. One of the mathematical skills that students must possess and achieve is problem solving (Pohan, 2020).…”
