Abstract

The inductive thinking learning model is a learning model based on processing information, with this model students are required to actively learn independently, discover concepts and ideas, and develop critical thinking skills which ultimately influence problem solving. This research aims to determine the effect of the inductive thinking learning model on the mathematical problem solving abilities of PAB Medan Estate Private Vocational School students. This research was carried out in March – May 2024. The research population for all 10th graders was 40 people. The sample was taken by purpose sampling as many as 40 people. This research is quantitative research, the method used in this research is pre-experimental design in the form of one group pretest and posttest. Before being given treatment, a diagnostic test is first carried out to determine the student's metacognitive ability to see how much their metacognition fails in solving statistical problems. Further grouped into high, medium and low metacognitive failure. After being given treatment, namely the inductive thinking learning model assisted by GeoGebra, a posttest was given with the same questions as the pretest in the form of questions describing statistical material. The research results show a significant influence of the GeoGebra-assisted inductive thinking learning model on students' mathematical problem solving abilities.

Abstract

This study aims to describe the influence of mathematical disposition on problem-solving ability through video-assisted learning in seventh-grade mathematics at a junior high school in Gunungsitoli City. The research employed a quasi-experimental design, with class VII-A as the experimental group (n = 32) receiving video-assisted instruction and class VII-B as the control group (n = 32) using conventional methods. Data were collected through problem-solving ability tests and mathematical disposition questionnaires, administered as pre-tests and post-tests. Analysis was conducted using t-tests and linear regression analysis. Results showed a significant improvement in problem-solving ability in the experimental class compared to the control class, with gain scores of 0.50 and 0.25 respectively. For problem-solving ability, the experimental class improved from a pre-test average of 67.34 to a post-test average of 83.78, while the control class improved from a pre-test average of 66.22 to a post-test average of 73.84. The mathematical disposition analysis yielded scores of 79.31 for the experimental class and 72.06 for the control class. Findings indicate that students who participated in video-assisted learning demonstrated significant improvement in problem-solving ability compared to the control group. Furthermore, students' mathematical disposition positively correlated with this improvement. This suggests that the video-assisted learning approach has potential in facilitating the development of mathematical problem-solving skills, while acknowledging the role of mathematical disposition in the learning process.

Abstract

Ethnomatics integrates local culture in mathematics learning. Traditional games become ethnomatic when used as a means of learning mathematics. In the Simalungun area, a traditional margala game competition was held. In the margala game there is an educational element, through the margala game the player's character values ​​can be developed. Margala games can be created to improve understanding of Mathematics subjects, moreover by applying mathematics during the game, the chances of winning the game are greater. Through this research, it can be seen the closeness of mathematics to local culture. This research aims to find strategies to get points when you are on the attacking team and to prevent getting points when you are on the guard team. to win the traditional game of margala, by utilizing concepts in mathematics, namely Geometry and Graphs. The research was carried out through literature study, observation, interviews, field notes and documentation on the players and coaches of the margala team at SMP Negeri 3 Jorlang Hataran and continued by analyzing the data. The use of geometric concepts in traditional margala game strategies, obtained by understanding the concepts of area and perimeter in rectangular shapes related to the length of the player's hand or reach, as well as position on the field can produce an effective strategy for winning the game. Apart from that, by using graph theory you can predict your opponent's movements and find the shortest route and avoid being touched by your opponent.

Abstract

This study aims to determine students' mathematical abstraction ability, answer process and difficulties faced by students in solving derivative problems. The subjects in this study were 11th grade students of SMA SWASTA AN - NIZAM Medan who were taught with the application of PBL model and scientific approach. The instrument in this study is a formative test used to see the level of mathematical abstraction ability and the answer process given by students. The difficulties faced by students in the process of solving the problems given can be known through the interview process conducted and documented through cell phones. Of the 19 students who took the math abstraction ability test, 4 students had high category math abstraction ability (21%). 11 students have medium category math abstraction ability (58%), and 4 students have low category math abstraction ability (21%). Of the 4 problems given, for the recognition stage, problem no 1 can be solved by all students. problem no 2 can be solved by 17 students, problem no 3 can be solved by 12 students and problem no 4 can be solved by 8 students. The decline also occurred at the representation and structural abstraction stages. After being analyzed based on the process of answers given by students and the results of interviews conducted, the decline was caused by: 1. the level of difficulty of the problem, 2. learning experience, 3. reasoning power and 4. literacy skills of each different student.. In this research, the media used to help the research process is geogebra. The use of this media is only limited to how to solve the problems given in other ways besides the concepts taught at school.Keywords: Qualitative Research Analysis; Mathematical Abstraction Ability; Problem Based Learning Model
