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

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.

Abstract

This study seeks to identify learning models that influence students' mathematics learning outcomes. Based on the level of absorption, the learning outcomes of the SMK Terpadu Jannatul Firdaus students have not yet reached the KKM and the learning outcomes in mathematics are not good or low, especially in the field of quadratic function equations, due to the not optimal indicators of the learning process at the school. One solution that can be applied is the Think Pair Share (TPS) learning model assisted by GeoGebra Software. This quantitative experimental research used a quasi-experimental design, namely the Posttest Only Control Design with a population of all students of class XI at SMK Terpadu Jannatul Firdaus. The sampling technique used cluster random sampling with three randomly selected samples, two as the experimental class and one as the control class. The first experimental class was taught through the application of the TPS learning model assisted by GeoGebra Software, the second experiment used the TPS learning model only, and the third was used as a control class using the conventional model. The research instrument uses a mathematics learning achievement test instrument. The research hypothesis uses Anova test and post-Anova test. The results showed that students who were taught using the TPS model assisted by the GeoGebra Software obtained a better average and outperformed compared to students who were taught using the conventional model or only the TPS model, as calculated in this study, Fcount was 8.620, which was greater than Ftable, which was 3.096.
