Abstract

The ability to solve students' mathematical problems cannot be diagnosed clearly just by using test questions; it must also be seen by looking at students' responses to the problem-solving process. As a result, the purpose of this study is to investigate students' mathematical problem-solving skill as well as their responses to the problem-solving process. This study is descriptive-qualitative in nature. Three junior high schools (SMP) in Aceh participated in this study, with 76 class VIII students serving as research subjects. Tests, observations, and interviews were used as data collection techniques. Quantitative data were descriptively analyzed using proportions, while qualitative data were descriptively analyzed using coding. The results showed that 25 percent of students wrote down what was known and asked, which was an indication of problem comprehension; 21 percent of students were able to devise problem-solving strategies; and 15 percent of students had done calculations correctly. correct, 11 percent of students checked their answers again. Based on the responses given by students, there were some difficulties experienced by students when solving math problems, namely difficulty understanding reading texts, using mathematical terms, making problem connections, making decisions, uncertainty in solving problems, time, carelessness, and boredom. The findings of this study are expected to serve as a resource for teachers and education practitioners in developing focus, discipline, and patience in problem solving and selecting learning models appropriate to the needs of their students.

Abstract

PISA is a prestigious platform for assessing students' learning achievements globally, including 4C skills: creative thinking, critical thinking, communication, and collaboration. However, the 2022 PISA results once again showed disappointing achievements for Indonesia. Indonesian students struggle with solving complex problems (critical thinking), have difficulty conveying ideas effectively (communication), are less prepared for creative challenges (creative thinking), and lack effective collaborative learning approaches. This research aimed to analyze the 4C skills of students at SMP Negeri 31 Medan. The study involved 29 students from class IX-3. Data were collected using two selected essay questions from the 2022 PISA mathematics test, specifically designed to assess 4C skills through indicators like interpreting, formulating, and reasoning. Collaboration was assessed through semi-structured interviews with the class teacher to gain insights into students' interaction and teamwork skills, complementing the written test results. Qualitative descriptive analysis was used to interpret students' written responses, while collaboration data were analyzed based on teacher observations. Assessment criteria followed established indicators for critical thinking (Employ and Evaluate), creativity (formulate), communication (interpret), and collaboration (effective teamwork). The results indicate that 69.56% of students correctly answered interpretation questions (communication, level 3), 39.13% and 43.47% answered employability questions correctly (critical thinking, levels 2 and 1a), and 30.43% correctly answered formulation questions (creativity, level 2). However, teacher observations revealed that students still struggle with effective collaboration, reflecting a broader challenge in fostering teamwork and peer learning. Overall, although communication skills are relatively strong, significant improvements are needed in critical thinking, creativity, and collaboration.

Abstract

Negara memandang mahasiswa sebagai harapan bangsa karena ekspektasi tinggi terhadap potensi mereka, namun banyak mahasiswa justru menunda belajar dan penyelesaian tugas. Penelitian ini bertujuan untuk mengetahui hubungan antara Intensitas menonton seri drama Korea dan Self-Criticism dengan Prokrastinasi akademik mahasiswa Surabaya. Penelitian ini menggunakan pendekatan kuantitatif. Populasi dalam penelitian ini adalah mahasiswa di Surabaya. Partisipan penelitian sebanyak 241 mahasiswa yang diambil menggunakan teknik accidental sampling. Hasil penelitian menunjukkan bahwa ada korelasi positif dan signifikan dari hubungan variabel intensitas menonton drama Korea dengan prokrastinasi akademik, dan Self-Criticism dengan prokrastinasi akademik. Penelitian ini menyimpulkan perilaku prokrastinasi akademik mahasiswa muncul dari intens atau keseringan mahasiswa dalam menonton drama Korea dan kritik diri yang berlebih. Implikasi hasil penelitian dapat digunakan sebagai panduan untuk mengurangi tingkat penundaan akademis yang tinggi dengan menginstruksikan mahasiswa untuk mengurangi kritik diri mereka dan intensitas mereka menonton drama Korea.

Abstract

Kemampuan literasi matematis merupakan kemampuan matematis yang sangat penting untuk dikuasai oleh siswa. Literasi matematis dapat diartikan sebagai pengetahuan untuk mengetahui dan menerapkan matematika dasar dalam kehidupan sehari-hari. Literasi matematis meliputi kemampuan seseorang untuk merumuskan, menerapkan, dan menafsirkan matematika dalam berbagai konteks, termasuk kemampuan melakukan penalaran secara matematis dan menggunakan konsep, prosedur, dan fakta untuk menggambarkan, menjelaskan, atau memperkirakan fenomena atau kejadian.  Selain itu, keterampilan sosial juga merupakan hal yang penting dikuasai oleh siswa dalam pembelajaran matematika. Dengan adanya keterampilan sosial, siswa dapat dengan mudah berinteraksi dengan orang lain. Sehingga diharapkan dapat dengan mudah dalam menyelesaikan permasalahan matematika. Salah satu model pembelajaran yang dapat meningkatkan keterampilan sosial adalah model project based learning. Model ini memudahkan siswa untuk saling berinteraksi dalam pengerjaan proyek. Penelitian ini bertujuan untuk melihat bagaimana kemampuan literasi matematis dan keterampilan sosial melalui model project based learning. Jenis penelitian ini adalah kualitatif dengan metode penelitian studi pustaka (library research). Teknik pengumpulan data dilakukan dengan cara mencari sumber seperti buku, jurnal, dan hasil-hasil penelitian yang telah ada.  Hasil dalam penelitian ini adalah model project based learning dapat meningkatkan kemampuan literasi matematis dan keterampilan sosial siswa.

Abstract

This research aims to determine: (1) To examine the differences in increasing representational abilities and mathematical learning independence for students who are given learning using the activity elicitation model and students who are given scientific learning. (2) To learn about the process of responding to kids who learn utilizing the activity elicitation approach. Those who approach learning scientifically. This is an example of experimental study. This study's population consisted of all pupils in class VIII of SMP Asy-Syafiiyah Medan, and the research sample was drawn at random from two classes. The study's findings indicate that (1) beginning mathematics abilities have an impact on students' mathematical representation abilities and (2) abilities have an impact. Students' independence in early mathematical learning. The increase in mathematical representation abilities of students who get MEA learning and those who receive scientific approach learning differs. (2) Using the eliciting events learning model to complete student answers is superior to learning using a scientific approach. Thus, scientifically based learning activity elicitation models can be employed as an alternative in learning mathematics to increase mathematical representation abilities.
