Abstract

This research aim to obtain description about applying Cooperative Learning of NHT with the assist of Posinega card able to improve student concept understanding on addition and subtraction of integer. This research was a classroom action research which refers to the Kemmis’ and Mc. Taggart’s design, that is plan, action and observation, and reflection. This research consist of two cycles, and each of the cycles was held in two meeting. The results of this research indicating that through applying of Cooperative Learning of NHT student concept understanding can increased, with the steps of Cooperative Learning of NHT (1) convey the learning purpose and motivating, (2) Presenting information, (3) numbering, (4) questioning, (5) heads together, (6) answering, and (7) giving appreciation. At the 1th phase, researcher convey the learning purpose and benefit to motivate the students; at the 2nd phase, researcher  presented addition and subtraction of integer through the demonstration of posinega card usage; at the 3rd phase, researcher divided the students into some groups, and gave number to each member of group; at the 4th phase, researcher gave task in worksheet to the students; at the 5th phase, the students were asked to think together in doing their worksheet and researcher guided them to do that; at the 6th phase,  researcher mentioned one number and the students who have the number presented their worksheet in front of the class; and at the 7th phase, researcher gave appreciation to each group.

Abstract

This study aims to obtain a description of the profile of creative thinking of class X high school students in solving mathematical problems in terms of Adversity Quotient (AQ). The subjects of this study were high school students of class X who had AQ with quitter type (SQT), camper (SCP), and climber (SCB). Data collection used test methods, methods of thinking, interviews, and observation. The results of this study are: a) SQT showes the existence of fluency and flexibility in the answer, namely by writing different ways and there were ways with the same pattern. The ways that he used were new ways for her which means that SQT has a novelty in solving problems. b) SCP also showed fluency, flexibility and novelty. The two ways he given were different from the other subjects, there were answers with the same pattern, and the method used was an unusual method. c) SCB showed excellent fluency and flexibility through the three ways he used it to solve problems. All the ways that he used were new ways for her, and he is willing to solve any problems after the problem.

Abstract

Abstrak: Penelitian ini bertujuan untuk memperoleh deskripsi tentang penerapan model pembelajaran kooperatif tipe NHT berbantuan media kartu posinega yang dapat meningkatkan pemahaman konsep siswa pada materi penjumlahan dan pengurangan bilangan bulat. Jenis penelitian ini adalah penelitian tindakan kelas (PTK) yang mengacu pada desain penelitian Kemmis dan Mc. Taggart, yakni perencanaan, tindakan dan observasi, dan refleksi. Penelitian ini terdiri dari dua siklus, dan masing-masing siklus dilaksanakan dalam dua kali pertemuan. Hasil penelitian menunjukkan bahwa penerapan model pembelajaran kooperatif tipe NHT berbantuan media kartu posinega yang dapat meningkatkan pemahaman siswa pada materi penjumlahan dan pengurangan bilangan bulat, dengan mengikuti fase-fase model pembelajaran koopertatif tipe NHT yaitu (1) menyampaikan tujuan pembelajaran dan memotivasi siswa, (2) menyajikan informasi, (3) penomoran (numbering), (4) mengajukan pertanyaan (questioning), (5) berpikir bersama (heads together), (6) menjawab pertanyaan (answering), dan (7) memberikan penghargaan. Pada fase 1 peneliti menyampaikan tujuan pembelajaran dan manfaat pembelajaran untuk memotivasi siswa; pada fase 2 peneliti menyajikan materi penjumlahan dan pengurangan bilangan bulat melalui pendemonstrasian kartu posinega; pada fase 3 peneliti membagi siswa ke dalam beberapa kelompok kecil, kemudian memberi nomor kepada setiap anggota kelompok; pada fase 4 peneliti memberikan soal-soal kepada siswa dalam bentuk LKS; pada fase 5 siswa diminta untuk berpikir bersama dalam menyelesaikan soal-soal pada LKS dan peneliti memberikan bimbingan seperlunya; pada fase 6 peneliti menyebut 1 nomor dan siswa yang memiliki nomor tersebut mempresentasikan hasil LKS kelompoknya di depan kelas; dan pada fase 7 peneliti memberikan peghargaan kepada setiap kelompok.

Abstract

Artikel ini menyajikan hasil penelitian tentang refleksi praktik mengajar pada penerapan model Project-Based Learning (PjBL) dalam materi anuitas pada mata kuliah Matematika Ekonomi di Program Studi Pendidikan Matematika, Fakultas Keguruan dan Ilmu Pendidikan, Universitas Tadulako. Penelitian reflektif ini bertujuan menggambarkan proses perencanaan dan pelaksanaan pembelajaran, capaian hasil belajar mahasiswa, serta tantangan yang muncul selama implementasi. Subjek refleksi adalah 56 mahasiswa semester tiga pada tahun akademik 2025/2026. Pengumpulan data dilakukan melalui observasi kelas, dokumentasi proyek berupa laporan tertulis dan presentasi kelompok, catatan aktivitas belajar, serta lembar refleksi mahasiswa. Temuan penelitian menunjukkan bahwa penerapan PjBL meningkatkan motivasi belajar, keterlibatan aktif, dan pemahaman konseptual mahasiswa terhadap konsep nilai waktu uang, termasuk present value dan future value. Temuan penting lainnya adalah meningkatnya kemampuan mahasiswa dalam komunikasi matematis melalui penyajian data, penjelasan grafik, dan diskusi kelompok. Kendala utama yang ditemui meliputi keterbatasan waktu penyelesaian proyek serta variasi kontribusi individu dalam kelompok. Secara keseluruhan temuan penelitian ini menegaskan bahwa PjBL memberikan pengalaman belajar yang lebih bermakna, kontekstual, dan relevan bagi mahasiswa dalam memahami konsep anuitas.
