Abstract

As many as 7.03% of people with disabilities in Indonesia are deaf people. The problem for deaf students is the lack of mathematics learning resources during learning and the low mathematical communication skills of deaf students. The purpose of this study is to analyze the development of sign language learning videos to improve mathematical communication of deaf students of fractional material in terms of validity, practicality, and effectiveness. The method used is the R&D method with a 4D model. The results showed that the validity of the media resulted in a very valid category by sign language experts with a score of 85% and material experts with a score of 83% and categories valid by media experts with a score of 78.5%. The results of media practicality of 100% for teacher and student responses and learning implementation questionnaires are said to be very practical. The results of the control class pretest and the experiment resulted in a sig value. > 0.05, then the data is normal. Homogeneity test with (6,14) <  (19) on pretest questions and (4,68) <  (19) on posttest questions then homogeneous data. Student scores resulted in a difference in the average student learning outcomes between the experimental class and the control class indicated by the T test results with the sig value. (0.001) < 0.05. The average value of the N Gain of the experimental class is greater than that of the control class, which is 0.9721 with a high category. so that the media is said to be valid, practical, and effective.

Abstract

The study aims to determine the effect of the problem-based learning (PBL) model assisted by Google Site on the students’ mathematical concept understanding ability. This type of research uses quantitative research with an experimental method. The subject is two classes, 30 students in VIII G as the experimental class and 30 students in VIII I as the control class. The data collection technique uses a description test in the materials in flat-sided shape and interviews for observation. Technique data analysis using the t-test with SPSS version 26 and determining the magnitude of the effect using the effect size test. The result obtained that the average mathematical concept understanding ability of students who receive learning with the PBL model assisted by Google Site is better than students who receive learning with conventional learning. Thus, it can be shown that a significant effect of applying the PBL model assisted by Google Site on the mathematical concept understanding ability. The effect size on the students’ post-test is 1.85. This shows that the effect of the problem-based learning model assisted by Google Site on the students’ mathematical concept understanding ability is in the high category.

Abstract

The development of technology is certainly very helpful for developing the world of education. But, many learning activities are carried out using conventional methods, namely lectures with books and blackboards which result in boring learning and poor critical thinking skills on the initial test. The purpose of this study was to determine the level of validity, practicality, and effectiveness of interactive media used to improve critical thinking skills. Research using the ADDIE model shows that the developed interactive media has very valid criteria based on the media validator's assessment of 97.67 and the material validator's assessment of 57 categories. The media developed with very practical criteria based on student practicality questionnaires of 85.06% and teacher practicality questionnaires of 96% categories. In addition, the developed media obtained an effectiveness score of 90.63% based on the posttest of critical thinking skills. From the above findings, it can be concluded that interactive media can be used validly, practically, and effectively to improve critical thinking skills.

Abstract

Growing student motivation is one of the techniques in developing the ability and willingness to learn. The purpose of this study was to determine the effect of instructional media on students' learning motivation in mathematics in elementary schools. This type of research is "ex post facto" with a research design using a one-shot case study. The subjects in this study were class IV students at SDN 028 Kubang Jaya class A and B, each of which had 15 students. The sampling technique uses non-probability sampling, namely purposive sampling. The research instruments used were observation and questionnaires. The data analysis technique uses product moment correlation with the help of SPSS 23. SPSS analysis of the product moment correlation shows the significance level of sig. (2-tailed) = 0.531, it can be concluded that the two variables are included in the "enough" category. From this analysis it can be concluded that there is an influence of learning media on learning motivation of 28.19%, other variables not mentioned in the study reach 71.81%.

Abstract

The low independence of student learning, especially in mathematics lessons, is a driver for research. Based on observations, most students do not realize the importance of learning independence. Many students don't want to learn math, and most don't like it because they think math is too difficult. Survey methods with simple regression analysis are used in research. The study aims to determine the effect of independence on mathematics learning achievement of seventh grade students at State Junior High School 7 Bekasi City in the even semester of the 2022/2023 academic year. Sampling using a simple random sampling technique with 38 students from seventh grade at Junior High School 7 Bekasi City. Data analysis using the help of the Statistical Program for Social Science (SPSS) 22 program with stages of descriptive statistical analysis, testing prerequisites for data analysis (normality test, linearity test, and hypothesis test). The results of the study can be concluded that there is an influence of independence on mathematics learning achievement in seventh grade of junior high school students. The effect of independence on students' mathematics learning achievement was 10.4%, and 89.6% was influenced by other factors.

Abstract

The lack of information about designing buildings, measuring, patterning and calculating from ancient people, makes the concept of mathematics applied by people in the past remains unknown. It is necessary to study mathematics from a cultural point of view of society. This study is carried out through a cultural approach, or what is commonly referred to as ethnomathematics. Mathematics that is used by recognized cultural groups, such as national communities, ethnic groups, labor organizations, children of particular age groups, and professional classes, is known as ethnomathematics. Finding the mathematical principles used to construct the Gedong Songo Temple in Candi Village, Bandungan, Semarang Regency, Central Java, is the goal of this study. The object of research in this case is the Gedong Songo Temple. The approach taken is a qualitative one. In this study, an ethnographic technique was used. Data collection is done by literature study and observation. This research is structured descriptively, starting from reviewing problems related to ethnomathematics, formulating problems, collecting theories, analyzing, discussing data, and making conclusions. The findings demonstrated that geometry, symmetry, periodic patterns, and ratios are among the mathematical concepts used in the construction of the Gedong Songo Temple. The findings of this study can be used to improve mathematics instruction in cultural contexts. In addition, further studies on ethnomathematics can be carried out to see more comprehensively the mathematical concepts applied to the structure of the temple building.
