Abstract

The development of effective, practical and valid Interactive PPT learning media is the goal of the research conducted. The R&D method with the ADDIE model was used as a method and model in this study. The research was conducted at SMP Negeri 4 Darangdan using subjects of 10 9th graders in a limited trial and 30 grade 8 students in a large trial. The instruments used are test and non-test instruments which include expert validation sheets, practicality sheets and pretest and posttest questions. Interactive PPT learning media obtained a very valid/feasible category based on the validation of media experts and subject matter experts, very practical from the results of extensive and limited trials and effective based on the results of effectiveness calculations after being given learning using interactive PPT media with the Discovery learning model with the calculation of N-Gain values in the high category. So it can be concluded that Interactive PPT media with the Discovery Learning  model is very valid/feasible, very practical, and effective in mathematics learning.

Abstract

Differentiated learning is learning that prioritizes and facilitates student needs according to student characteristics, one of which is learning readiness, which consists of groups ready for challenges, understanding concepts and repeated concepts. From these three groups, it will be analyzed how learning obstacles occur in analyzing the circle concept. This research is a qualitative descriptive study with 15 research subjects. Based on the results of data analysis, it can be concluded that the group of students who understand the concept and repeat the concept experience epistemological obstacles in understanding the relationship between the central angle and the circumferential angle, analyzing the area of a circle, analyzing the elements of a circle, and analyzing the relationship between the central angle and the area of the circle. Apart from that, students experience difficulty in representing the problems given because students are unable to find information and instructions from the questions given.

Abstract

This research aims to see whether there is an increase in students' mathematical communication skills after being given learning using the discovery learning model. This research was carried out at MTsN 04 KBB in class VIII with a total of 20 students. The learning instruments and tools used are Pretest and Posttest questions as well as LKPD which contains material regarding circles and stages of discovery learning. The results of the data obtained will be analyzed and managed using 2 dependent sample analysis using a normality test first and followed by a paired t-test. The results of the analysis test show that there are significant differences and there are differences in the average results of the pre-test and post-test, and at the end it is shown that students' mathematical communication skills have increased.

Abstract

This research was motivated by the low mathematical communication skills of high school students, this research was carried out at SMP Dharma Kartini in grade VII as many students. The instrument used was a mathematical communication ability description test. The purpose of this research is to improve students' mathematical communication skills and the achievement of students' learning goals using the Problem Based Learning (PBL) model assisted by audiovisual media. The data from the study were processed using 2 independent samples using the normality test and the Monte Carlo test. The results of the analysis showed that grade VII junior high school students who used the Problem Based Learning (PBL) model with the help of audiovisual media got a better increase in mathematical communication skills compared to students who used the conventional learning model. Furthermore, students who get an improvement in learning using the Problem Based Learning (PBL) model assisted by audiovisual media also experience achievement in learning objectives.

Abstract

This research aims to analyze and examine the improvement of seventh-grade junior high school students’ mathematical reasoning abilities using the problem-based learning model assisted by VBA for Excel, compared to the conventional learning model. The research method used is an experimental method with a quasi-experimental design, consisting of two groups, the experimental class and the control class. This research was conducted at SMP Negeri 2 Batujajar, with the sample comprising of class VII-D as the experimental class and class VII-B as the control class, each with 29 students. The instruments and learning materials used include a mathematical reasoning ability test and student worksheets (LKPD) containing material on plane figures according to the stages of problem-based learning. The data obtained will be analyzed using inferential statistics. The results of this research indicate that the improvement in students’ mathematical reasoning abilities using the problem-based learning model assisted by VBA for excel is better than that of those using conventional learning.

Abstract

This study sought to ascertain whether students' comprehension of mathematical topics had increased as a result of using Discovery Learning with GeoGebra. This study employed a mixed model with a convergent parallel design. 58 eighth-graders from SMP Negeri 5 Purwakarta served as the subjects. Two groups of students were created: an experimental group and a control group. Pretests, posttests, and student response surveys were used to gather data. The Mann-Whitney test, normality, and N-Gain were used to assess the data. According to the data, both groups improved in the moderate category; nevertheless, the experimental class's average N-Gain (0.51) was higher than the control class's (0.38). The Mann-Whitney test findings showed a significant difference (sig. 0.004 < 0.05). Thus, the GeoGebra-assisted discovery learning model enhances conceptual mathematical knowledge more effectively than conventional learning. Furthermore, learning that encourages active participation in discovering ideas is well-received by students.
