Ethnomathematics: Exploration of Geometric Concepts in Traditional Paintings and Carvings of Teluk Ampimoi Kepulauan Yapen, Papua, Indonesia, as a Source of School Mathematics Learning

This research explored the mathematical concepts contained in the traditional paintings and carvings of Teluk Ampimoi Kepulauan Yapen, an indigenous district in the Kepulauan Yapen Regency, Papua, Indonesia, that can be used in school mathematics instruction and learning. Ethnographic research with an ethnomathematical research model was used. Data was collected using participant observation and in-depth interview techniques and was analysed using taxonomic, domain, and ethnographic methods. The results showed that the various forms of traditional paintings and carvings of Teluk Ampimoi, Kepulauan Yapen exhibit mathematical concepts in the form of geometry, namely plane geometry and transformation geometry and approximation, namely, measurement. Based on the taxonomic analysis, it was found that the geometric concepts can be integrated with mathematics learning in schools in the field of geometry concerned with the properties, perimeter, and area of rectangles, parallelograms, and triangles. In addition, the geometric transformation contained in the items related to reflection

Pelatihan Pembelajaran Daring Menggunakan Google Classroom Pada Guru-Guru di Provinsi Papua

During the Covid-19 outbreak, the use of online learning presented a challenge for educators in the province of Papua. In Papua Province, 99 participants from 12 districts and cities participated in the training session utilizing Google Classroom. Training activities were carried out online using the zoom meeting application. The purpose of this training is to help and equip teachers to carry out online learning using the google classroom application. Participants were taught how to build classes, make announcements, create discussion forums, upload subject matter, assignments, and exam questions, construct quizzes and exam questions using google forms, and were given a simulation of how to utilize google classroom capabilities. The service's results suggest that users truly require training to advance their knowledge and abilities utilizing online learning tools like google classroom. After attending the training, participants have improved their knowledge and abilities in utilizing google classroom, have improved levels of creativity and expertise to create online courses, and have a high degree of satisfaction. Given that the Covid-19 pandemic is not known to have an end date and that the industrial revolution 4.0 and the industrial revolution 5.0 are both upon us, it is imperative that online learning training for teachers be conducted continually

Comparison of Student Achievement in Teaching Analytic Geometry of Planes and Space Using GeoGebra and PowerPoint Media at STKIP Abdi Wacana in Semester VI of the Academic Year 2021/2022 in Wamena

The research examines the comparison of student learning achievement on the topic of analytic geometry of planes and spaces, which is taught using two different learning media, namely GeoGebra and PowerPoint media. This experimental research used two different experimental classes, each consisting of 14 and 15 students. The research design used is a counterbalance design because even though students' initial knowledge is homogeneous, there are still many other variables that affect the process and learning outcomes, which cannot be controlled and are not homogeneous. The research data used were pre-test and post-test scores for each treatment, which were then processed to obtain normalized gain data. Data processing was carried out using SPSS software and was preceded by an analysis of homogeneity tests and normality tests. Based on the Wilcoxon Signed Test, it is clear that the two learning media are able to improve student learning outcomes. The paired samples test is used to compare the learning outcomes of the two learning models. The results showed that learning using GeoGebra media gave higher learning outcomes compared to using PowerPoint media. The average normalized gain difference between the two media is 0.34
