Abstract

This research aims to investigate the effect of the Problem-Based Learning (PBL) learning model on the mathematical communication skills of class XI MAS students at the UNIVA Medan Project, with the help of the FlipHTML5 application. The method used in this research is quasi-experimental with a factorial design. Data collection was carried out through mathematical communication skills tests and statistical analysis to test hypotheses. The results showed that there was a significant increase in the mathematical communication skills of students in the experimental group compared to the control group. The average posttest score for the experimental group was 85.52, while the control group was 78.04. It is indicated that this difference did not occur by chance, but rather was the result of differences in the treatment applied. In addition, the FlipHTML5 application was proven to be effective in improving students' mathematical communication skills with an average score percentage of 73.63% in the experimental class compared to 71.37% in the control class. These results indicate that the use of the FlipHTML5 application in learning with the PBL model makes a positive contribution to improving students' mathematical communication skills.

Abstract

Mathematics learning at the elementary school level often faces serious obstacles when entering the material of integer arithmetic operations, which is caused by the abstract nature of the concept for students at the concrete operational stage. This community service activity aims to train and improve the ability of integer arithmetic operations in children at the Fadilla Rahma Foundation through the use of slide rule props. The implementation methods used in this service include interactive lectures, demonstrations of tool use, and guided independent exercises. The activity participants consisted of 15 elementary school students who were members of the skilled reading and numeracy classes. The results of this activity show a significant increase in students' knowledge and skills. Before the intervention, students had difficulty visualizing the direction of number movements on negative numbers, but after using the slide rule, students were able to master the calculation steps with an accuracy rate of 90%. The use of slide rule media has proven effective in transforming abstract concepts into concrete ones, making it easier for students to understand the logic of addition and subtraction of integers. In addition to cognitive improvement, this activity also succeeded in awakening students' motivation and self-confidence in working on mathematics problems. The conclusion of this service is that slide rule props are a very representative and effective learning medium to be used at the elementary school level to strengthen children's numeracy foundations. It is recommended for educators to continue integrating physical props in mathematics learning to create a meaningful and enjoyable learning experience.

Abstract

The ability to think creatively is the ability to generate new ideas or ideas in producing ways of solving problems, even producing new ways as alternative solutions. Creative thinking is very important in learning mathematics. The results of the study in the control class, namely classes using conventional learning models obtained pretest data with an average of (36%) and posttest data of (52%). While the experimental class is a class that uses creative thinking skills with a reciprocal teaching learning model assisted by the Geogebra application. Pretest data obtained an average score (18%) and posttest data obtained an average score (70%). The results of the study (1) rcalculate = 0.000 and rtabel value = 0.355 can be seen that the value of rcalculate ≤ rtabe so that it can be concluded that in this study there was an increase in creative thinking skills using a reciprocal teaching model assisted by Geogebra application to the linear inequality material of two variables in students using conventional model

Abstract

Students often have difficulty understanding the concept of transformation geometry because it is abstract and has little to do with the real context. One of the causes is less meaningful and non-contextual learning. Therefore, one of the efforts that can be made is based on local wisdom. On the other hand, e-learning as an educational innovation has been widely used, but its application has not been optimal, especially to explain visual and abstract concepts such as transformation geometry. Therefore, an e-learning approach is needed that integrates contextual problems based on local wisdom to improve student understanding. This study aims to discuss the effect of e-learning learning based on local wisdom problems on improving students' understanding of transformation geometry. The research was conducted at Al-Azhar High School Medan, the subject of class XII research was 146 students who were selected by random sampling to select samples. The type of research used was quasi-experimental with a pretest-postest control group design. Data collection used a transformation geometry understanding ability test, including indicators of translation, dilation, reflection and rotation. The significance value of the Independent Sample t Test 0.00 < 0.05 means that there is a significant difference in the increase (gain) of experimental students with the control class. Through these results, it can be concluded that e-learning based on local wisdom problems has an effect on improving students' understanding of transformation geometry. The results of the dilatation indicator gain were 0.51, translation 0.54, reflection 0.47, rotation 0.44 with each category moderate.
