Abstract

This study aims to analyze the errors of students with HOTS abilities at high, medium and low levels and identify student errors in solving HOTS (Higher Order Thinking Skill) type questions in terms of gender. This type of research is qualitative with a case study approach. The research subjects were selected 3 male students and 3 female students, each of which the HOTS ability level was high, medium and low consisting of 2 students. Data collection techniques used HOTS-type tests and interviews. The analytical framework was developed based on Newman's theory of error categories. The data obtained were tested for validity through credibility, transferability, dependability, and confirmability tests. The results showed several differences in the types and percentages of errors made by male and female subjects in solving HOTS-type questions. The biggest mistakes made by both genders in the material of number patterns, sequences, and series are misunderstandings of 33.33%, followed by errors in determining the final answer of 23.02%, transformation errors of 22.22%, errors in the completion process of 20.63%, and finally, reading errors of 0.79%. It can be seen that the female gender makes more mistakes by 57.14% compared to the male gender by 41.86%.

Abstract

Mathematics learning activities in schools tend to emphasize students to be able to solve problems with existing formulas. Likewise, teachers who pay less attention to and practice various problem-solving strategies. Thus, students are less able to express their thinking processes. This study aims to determine the students' mathematical thinking processes in solving mathematical problem-solving problems given. This type of research is descriptive qualitative with research subjects consisting of 6 students of class X Social Sciences SMA Islam Plus Adzkia Medan selected by purposive sampling method. The data collection technique was carried out using research instruments in the form of a description test which amounted to 3 questions and interviews. The results showed that the thinking processes used by students in solving problems were different. There are several problem-solving strategies used by students as a form of their thinking process. In the first question, there are three strategies used by students, namely act it out (conducting experiments), logical thinking, and different points of view. In the second question, all students used the strategy of registering all the possible answers that were explained directly or using the strategy of making tables. For the third question, there are two thinking strategies, namely by using formulas and strategies to find patterns. However, it was also found that there were still students who had inappropriate thinking processes.

Abstract

AbstrakPerkembangan ilmu pengetahuan dan teknologi saat ini semakin pesat dan secara luas menghasilkan produk yang memberikan kemudahan bagi manusia, baik dari segi ilmu pengetahuan, pendidikan, dan hiburan. Teknologi internet memberikan pengaruh yang besar dan beragam terhadap kehidupan manusia, salah satunya yang paling populer adalah dalam hal hiburan. Seperti halnya game online yang marak dimainkan oleh berbagai kalangan, terutama anak–anak. Game online yang tengah digandrungi oleh anak–anak saat ini salah satunya ialah Free Fire.  Game yang memiliki rating usia 12 tahun ke atas ini, nyatanya banyak dimainkan oleh anak di bawah umur yang masih rentan terhadap dunia luar. Dampak yang ditimbulkan dari game online tersebut membuat nilai–nilai yang terkandung dalam Pancasila yang seharusnya menjadi acuan dalam kehidupan, semakin terkikis seiring bertambahnya waktu. Artikel ini bertujuan untuk mengetahui bagaimana pengaruh game online tersebut terhadap sikap yang mengandung nilai–nilai Pancasila pada anak. Berdasarkan hasil analisis dan juga pengamatan, game online Free Fire tersebut memang berdampak cukup buruk pada anak.Kata Kunci : game online Free Fire, nilai–nilai Pancasila. AbstractThe development of science and technology is currently increasing rapidly and widely producing products that provide convenience for humans, both in terms of science, education, and entertainment. Internet technology exerts a great and diverse influence on human life, one of the most popular is in terms of entertainment. As well as online games that are widely played by various groups, especially children. One of the online games that are being loved by children today is Free Fire.  This game, which has an age rating of 12 years and above, in fact, is mostly played by minors who are still vulnerable to the outside world. The impact caused by these online games makes the values contained in Pancasila, which should be a reference in life, increasingly eroded as time goes by. This article aims to find out how the influence of online games on attitudes that contain Pancasila values in children. Based on the results of the analysis and also observations, the Free Fire online game does have a pretty bad impact on children. Keywords: Free Fire online game, Pancasila values.

Abstract

This research aims to determine the magnitude of the influence of the discovery learning model on students' mathematical abilities. These included problem-solving skills, critical thinking, understanding, and mathematical reasoning. This study employs a quantitative approach with a Meta-Analysis method. Data collected was from experimental research connected to the application of discovery learning models to the mathematical abilities of elementary, junior high school, and high school students in papers indexed from 2012 to 2021. From the search and study selection results, 48 articles were obtained. The findings found an annual increase in the number of publications, most of which were on mathematical reasoning abilities. Researchers also conducted more research at the junior high school education level, with a sample size of more than 30. Meanwhile, when viewed from the demographic aspect, this study is more located on the island of Java. The application of the discovery learning model to students' mathematical abilities has an overall effect size of 0.815 with the high effect category.

Abstract

Penelitian ini bertujuan untuk mengetahui besaran efek dan mendeskripsikan penelitian-penelitian pengaruh model Problem-Based Learning (PBL) terhadap peningkatan kemampuan matematis siswa. Kemampuan yang dapat ditingkatkan melalui Problem-Based Learning (PBL) yaitu kemampuan matematis reflektif, penalaran, berpikir kritis, spasial, komunikasi, representasi, dan koneksi. Metode yang digunakan dalam penelitian ini adalah metode meta-analisis. Pengumpulan data dilakukan dengan cara mendokumentasikan dan mengulas berbagai artikel yang memiliki keterkaitan pada topik penelitian. Jumlah artikel yang sesuai dengan karakteristik sesuai target, screening, dan kriteria inklusi eksklusi ditemukan 29 artikel (studi primer). Hasil penelitian menunjukkan bahwa pada periode tahun 2012-2021 kemampuan berpikir kritis matematis mendominasi hasil penelitian dalam peningkatan kemampuan matematis melalui Problem-Based Learning (PBL). Penelitian banyak dilakukan pada jenjang pendidikan Sekolah Menengah Pertama (SMP) di Pulau Jawa dan Bali dengan ukuran sampel 30 atau lebih. Metode penelitian dari studi primer yang digunakan didominasi oleh kuasi-eksperimen. Berdasarkan hasil penelitian kesimpulan penelitian-penelitian membuktikan nilai ukuran efek gabungan implementasi Problem-Based Learning (PBL) berpengaruh secara signifikan terhadap kemampuan matematis siswa dari studi primer yang dianalisis adalah 1.147 dalam kategori sangat tinggi. Model PBL sangat direkomendasikan untuk digunakan dalam upaya meningkatkan kemampuan matemasis siswa dan menanamkan konsep kepada siswa yang masih kurang efektif.
