“…Widiastuti & Nindiasari (2022) states that the lack of students' mathematical problem solving abilities is caused by various things such as students not communicating and interacting in class, the use of strategies, methods and learning models is still not implemented in the learning process, and the use of media is still underutilized. Indrayany & Lestari (2019), And Yeni (2011) in his research, The lack of appropriate geometry learning media to visualize objects is one of the causes of students' low ability to solve mathematical problems. Based on this, appropriate innovation is needed to develop students' mathematical problem solving abilities, especially in learning geometry.…”

Good mathematical problem solving skills are important for students because they are the goals and principles in learning mathematics. However, various studies, both national and international, state that students' mathematical problem solving abilities in Indonesia are still low. The Geogebra-assisted discovery learning model is an innovation that can be used to improve students' mathematical problem solving abilities. This research aims to analyze the influence of the Geogebra-assisted discovery learning model on students' mathematical problem solving abilities in geometry learning. The research method used is meta analysis. The articles analyzed are articles sourced from Scopus, ScienceDirect and Google Scholar with a period of 2013-2023. Of the 10 articles analyzed, 3 of them studied groups of middle school students, 4 groups of high school students, and 3 students. The results showed that 8 articles had a large effect size, 1 article was a medium size, and 1 article was a small size. The results of the Independent Sample t-test obtained tcount of 11.59 and ttable of 1.96. So it can be concluded that the discovery learning model assisted by Geogebra has an effect on students' mathematical problem solving abilities in geometry learning. Through the discovery model, students discover their own concepts and solve the problems. Geogebra is important for illustrating geometric problems. Future research can also analyze the extent of the influence of the Discovery Learning model assisted by Geogebra on students' mathematical problem solving abilities in terms of various other variables both from within the students and from the surrounding environment.

“…Previous studies show that the level of mathematical thinking ability, especially geometric thinking, for junior high school students in solving mathematical problems is in a low level (Junining et al, 2022;Kurniati et al, 2016;Ma'rifah et al, 2019;Megawati et al, 2019;Rabu & Badlishah, 2020). Likewise, there is a research on students' difficulties in solving geometry problems (Arifendi & Wijaya, 2018;Fauzi & Arisetyawan, 2020;Indrayany & Lestari, 2019;Maryanih et al, 2018;Sholihah & Afriansyah, 2017). One of the causes of students' lower thinking ability lies in the students' mindset which only focused on one solution without trying, analyzing and finding new ways and tended to use the same way or formula of solving problems as what has been given by the teacher.…”

[English]: There are two categories of thinking skills that influence each other in mathematical knowledge, namely a thinking process called ways of thinking (WoT) and ways of understanding (WoU). This study aims to describe students' WoT and WoU in solving mathematics problems in terms of adversity quotient (AQ). This research is descriptive and qualitative. The participants of this study were students at MTs Muhammadiyah 1 Taman Sidoarjo. The subjects were selected based on the results of the adversity response profile test using a purposive sampling technique, so there were 3 climbers, 3 campers, and 2 quitter. The written test and interview data were analyzed according to the WoT and WoU indicators. The results of this study indicate that the WoT climber students tend to have one strategy in solving mathematical problems that leads to the correct solution, an empirical WoT, and a very good belief in mathematical concepts. Meanwhile, the WoT campers and quitters tend to have one strategy that leads to wrong solutions, and beyond belief WoT. The camper students have good confidence, while quitter students have less confidence in mathematical concepts. The WoU climber students are in the very good category, camper students are enough, and quitter students are in the less category. The WoT and WoU of climber students are better than those of camper and quitter students. [Bahasa]: Terdapat dua kategori keterampilan berpikir yang saling mempengaruhi dalam pengetahuan matematika yaitu proses berpikir yang disebut ways of thinking (WoT), dan cara pemahaman siswa yang disebut dengan ways of understanding (WoU). Penelitian ini bertujuan untuk mendeskripsikan WoT dan WoU siswa dalam menyelesaikan masalah matematika ditinjau dari adversity quotient (AQ). Penelitian ini adalah deskriptif kualitatif. Partisipan dalam penelitian ini merupakan siswa di MTs Muhammadiyah 1 Taman Sidoarjo. Subjek dipilih berdasarkan hasil tes adversity respons profile menggunakan teknik purposive sampling, sehingga didapatkan 3 siswa climbers, 3 campers dan 2 quitters. Data tes tulis dan wawancara dianalisis sesuai indikator WoT dan WoU. Hasil penelitian ini menunjukkan bahwa WoT siswa climber dalam menyelesaikan masalah matematika cenderung memiliki satu strategi yang mengarah pada solusi benar, cara berpikir empiris, dan memiliki keyakinan yang sangat baik terhadap konsep matematika. Sedangkan WoT siswa camper dan quitter cenderung memiliki satu strategi yang mengarah pada solusi salah, dan cara berpikir luar keyakinan. Siswa camper memiliki keyakinan yang baik, sedangkan siswa quitter memiliki keyakinan yang kurang terhadap konsep matematika. WoU siswa climber berkategori sangat baik, siswa camper berkategori cukup. dan siswa quitter berkategori kurang. WoT dan WoU siswa climber lebih baik dibandingkan siswa camper dan quitter.

“…Dibandingkan cabang matematika lainnya, geometri memiliki kemungkinan yang lebih besar untuk dipahami siswa karena konsep geometri seperti garis, bidang, dan ruang sudah diketahui siswa sebelum masuk sekolah (Sholihah & Afriansyah, 2017). Hal ini tidak sejalan dengan yang terjadi dalam proses pembelajaran yang sesungguhnya karena masih ditemukan siswa kesulitan memahami konsep geometri dan hasil belajarnya juga rendah (Indrayany & Lestari, 2019).…”

Students are weak in visualization skills, so it is difficult to interpret geometric shapes. Therefore, learning media is needed that can help students learn flat side shapes, one of which is by using PowerPoint as an educational game. This research aims to describe the quality of PowerPoint-based educational games on the combined volume of flat side shapes in the eighth grade of junior high school. The development is carried out using the ADDIE model. The research subjects were 60 grade eight students of SMPIT Al-Uswah Banyuwangi. Data collection was carried out using interviews, observation, questionnaires, tests, and documentation. Data analysis with combined methods (quantitative and qualitative). The results showed that educational games were valid with an average score of 4.39, practical with an average score of 4.67 and the student responses were in a fairly good category with an average value of 3.94 and were not effective according to the analysis of test results which shows . So that the quality of the results of the development of PowerPoint-based educational games on the combined volume material for flat side shapes is not good and needs to be improved. Improvements can be made, especially in terms of sound so that it can be heard more clearly.
