Abstract

This study aims to determine the effect of the inquiry method on students' mathematical connection ability in Class X of SMK Swasta Teruna Padangsidimpuan. Mathematical connection ability is an essential competency in mathematics learning that includes students’ ability to connect mathematical concepts, relate mathematics to real-life situations, and apply various mathematical representations. This research is a quasi-experimental study using a Non-Equivalent Control Group Design. The sample consisted of two classes: the experimental class, which received treatment using the inquiry method, and the control class, which was taught using conventional methods, with 20 students in each class. The instrument used in this study was a mathematical connection ability test in the form of essay questions that had been validated.The results showed that the average post-test score in the experimental class was 77.05, while in the control class it was 53.90. The independent sample t-test resulted in a significance value of 0.000 < 0.05, indicating a significant difference between the two groups. Therefore, it can be concluded that the inquiry learning method significantly affects the improvement of students’ mathematical connection ability.

Abstract

This study aims: (1) To find out the improvement of students' mathematical problem solving by applying the Discovery Learning learning model to the subject of social arithmetic in class VII SMP Negeri 4 Muara Batang Gadis in the 2021/2022 academic year, (2) To determine the level of achievement of problem solving abilities. students' mathematics by applying the Discovery Learning learning model to the subject of social arithmetic in class VII SMP Negeri 4 Muara Batang Gadis for the 2021/2022 academic year, (3) To find out the management of learning carried out by the teacher by applying the Discovery Learning learning model based on problem solving on the subject of arithmetic Social studies in class VII SMP Negeri 4 Muara Batang Gadis teaching 2021/2022 This type of research is classroom action research. The level of problem solving ability in the first cycle is moderate with a class average score of 70.083 with 26 students (72.22%) Implementation of actions in cycle II, high The problem solving ability of students is high with a class average score of 80.47 with 35 students or 80.083% of all students. Thus it can be said that the class has been completed in learning, there are 80% of students who have a moderate level of problem solving ability.

Abstract

This The low ability of students' mathematical problem solving affects the success of a learning process. Learning model as a tool to achieve a goal. The better a learning model, the better the achievement. So one of the most important teacher tasks, before carrying out their duties is to know and apply the learning model, the model used in this study is the Number Head Together (NHT) cooperative learning model.This research is a classroom action research (CAR) by taking the research subjects of Class VIII-1 students of SMP Negeri 4 Muara Batang Gadis for the academic year 2021-2022. consisting of 22 students. The objects taken in the research are students' problem solving abilities, student learning activities in the implementation of classroom learning, teacher activities that specialize in the Number Head Together (NHT) type cooperative learning model to improve students' mathematical problem solving on the subject of Two Variable Linear Equation Systems ( SPLDV). The results of this study show that the problem-solving ability of students using the Number Head Together (NHT) type of cooperative learning model for Class VIII-1 students of SMP Negeri 4 Muara Batang Gadis in the 2021-2022 academic year has increased, it can be seen from the students' mathematical problem solving ability in the first cycle of 45 ,45% who completed the second cycle and 81.82% of students who completed the 22 students who took the study test. Based on the research data through the student observers, the percentage was 68.75% in the first cycle and 90% in the second cycle. Based on the research data through teacher observers, the percentage was 3.45 in the first cycle and 3.94 in the second cycle. So, it can be concluded that each cycle has increased and is included in the "very good" category and has met the research achievement criteria, so this research stops in cycle II.Based on these results, the application of the Number Head Together (NHT) learning model can improve students' mathematical problem solving skills on the subject of a two-variable linear equation system in class VIII-1 of SMP Negeri 4 Muara Batang Gadis in the 2021-2022 academic year.
