Abstract

Pancasila students embody Indonesian students who have competence and behave according to Pancasila values. One of the elements of the Pancasila profile is critical reasoning which is contained in advanced mathematics books and will be a provision for Indonesian students, especially phase E at SMA/SMK levels in an effort to develop themselves and face challenges in the 21st century. The purpose of this research is to analyze student books in accordance with aspects of the values of the Pancasila Student Profile which focus on elements of critical reasoning and provide recommendations as material for consideration in improving student books. This type of research is qualitative with a descriptive approach. The results obtained are books that are relevant and encourage students to reason critically by presenting various problem solutions, and there is a special column entitled "Mari Berpikir Kritis" in each chapter which leads students to reason critically in understanding various advanced issues. However, this book still has drawbacks, namely the critical thinking column in each chapter has a different presentation measure. This is due to the difficulty level of each chapter presented. Totally, this book has been able to become one of the supports in forming a nation's generation that has a critical reasoning dimension on the Pancasila Profile.

Abstract

The concept of mathematical material is still not fully embedded in students' schemes, this means that errors occur in constructing the concept. This research aims to describe the actual situation regarding pseudo-construction errors that occur at the APOS (Action, Process, Object, and Scheme) stages. This research involved 28 students in class VIII A of SMPN 2 Silo Jember as subjects through problem solving test to get an comprehensive information about occuring errors. Then by the purposive sampling and snowball sampling techniques, two subjects are choosen to explore in depth through interview. The data valiadation is guarantee through the member check process. Data analysis includie data condensation, data presentation, and concluding. The results of the research are that pseudo-construction errors occur at every stage of APOS which results in the concept not being fully constructed in the student's scheme. As a recommendation, developing a mathematics learning model based on APOS theory to minimize the error is needed such that the concepts will be well and completely constructed in students' schemes. Konsep materi matematika masih belum sepenuhnya tertanam dalam skema siswa. Hal ini menunjukkan bahwa terjadi kesalahan dalam mengkonstruk konsep. Penelitian ini bertujuan untuk menggambarkan atau mendeskripsikan keadaan yang sebenarnya terkait kesalahan konstruksi semu yang terjadi pada tahapan APOS (Aksi, Proses, Objek, dan Skema). Penelitian ini melibatkan 28 siswa kelas VIII A SMPN 2 Silo Jember sebagai subjek melalui tes pemecahan masalah untuk mendapatkan informasi komprehensif tentang kesalahan yang terjadi. Kemudian dengan teknik purposive sampling dan snowball sampling, dipilih dua subjek untuk dieksplorasi secara mendalam melalui wawancara. Validasi data dijamin melalui proses member check. Analisis data meliputi kondensasi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian yaitu kesalahan konstruksi semu terjadi disetiap tahapan APOS yang mengakibatkan konsep tidak terkonstruk dengan utuh dalam skema siswa. Sebagai rekomendasi, perlu dikembangkan model pembelajaran matematika berbasis teori APOS untuk meminimalkan kesalahan agar konsep-konsep dapat terkonstruksi dengan baik dan lengkap dalam skema siswa.

Abstract

Teori perilaku dalam pendidikan diterapkan melalui program dengan prinsip-prinsip behaviorisme, seperti penguatan positif dan negatif. Misalnya, penghargaan atau pujian diberikan untuk perilaku yang diinginkan, sementara tugas yang tidak disukai siswa dihilangkan ketika mereka menunjukkan perilaku baik. Namun, teori perilaku sering dikritik karena terlalu fokus pada perilaku yang dapat diamati dan kurang memperhatikan proses mental internal seperti motivasi, pemahaman, dan kreativitas. Pergeseran terlihat dengan munculnya teori pembelajaran kognitif dan konstruktivis yang menekankan peran aktif siswa dalam membangun pengetahuan mereka. Tujuan penelitian ini untuk menganalisis teori perilaku dalam pembelajaran dengan metode systematic literature reviewe. Kesimpulan bahwa teori perilaku dalam pendidikan dan kesehatan mental semakin relevan di era komputer dan internet saat ini. Perubahan perilaku yang disebabkan oleh kemajuan teknologi informasi tidak didukung oleh fondasi kepribadian yang kuat, terutama dalam hal agama dan karakter. Degradasi moral dan masalah adaptasi sosial muncul sebagai hasilnya. Teori perilaku seperti kesadaran metakognitif sangat penting untuk membantu siswa belajar, terutama matematika. Siswa yang mampu berpikir secara metakognitif mungkin lebih percaya diri dalam menyelesaikan masalah. Selain itu, literasi digital memainkan peran penting dalam mengajarkan perilaku berpikir kritis dan kreatif sambil mempertahankan nilai-nilai sosial, emosional, dan spiritual. Di era metaverse, teknologi seperti augmented reality dan virtual reality meningkat dalam pengajaran

Abstract

This study aims to develop Realistic Mathematics Education (RME) learning tools integrated with agricultural activities, fulfilling the criteria of valid, practical, and effective to improve numeracy skills, particularly in the topics of direct and inverse proportionality. This study used the research and development with the Plomp model, comprising three phases. The first phase, preliminary research, involved 26 teachers and prospective teachers. The second phase, development or prototyping, engaged three experts and three students. The third phase, assessment, was conducted through trial testing with 31 participants in the experimental class and 31 participants in the control class. Data collection techniques included questionnaires, surveys, observations, tests, and interviews. Data processing was conducted using descriptive statistics. The results of the study indicate that the developed RME learning tools integrated with agricultural activities fulfills the criteria of valid, practical, and effective. The validity criteria were achieved with scores of 3.77 for the teaching module, 3.81 for the LKPD, 3.84 for the learning achievement test, and 3.87 for the instruction manual. The practicality criteria were met with a learning implementation rate of 95% (very good), and student activity reaching 84.9% (active). Additionally, student and teacher response questionnaires showed positive feedback, with scores of 95.48% and 100%, respectively. The effectiveness criteria were achieved with an average N-Gain score of 0.65 (moderate) and the experimental class achieved higher average scores than the control class. This study implies that RME integrated with agricultural activities can be recommended for mathematics teachers to support numeracy teaching.

Abstract

Mathematics is an important foundation in developing critical and logical thinking skills, which are reflected through mathematical literacy. However, PISA 2022 scores show that Indonesian students' mathematical literacy is still below the international average, with the main weakness in solving HOTS questions. This qualitative research aims to analyze the relationship between self-regulated learning (SRL) and students' mathematical literacy in solving HOTS problems related to System of Linear Equations of Three Variables (SPLTV) at Singa Putih Munfaridin Islamic Boarding School, Pasuruan. Data were collected through HOTS tests, SRL questionnaires, and interviews with grade X students who were grouped into three SRL categories: low, medium, and high. The results showed that students with high SRL could formulate problems efficiently, apply systematic strategies, and interpret solutions independently. Medium SRL students have difficulty in applying concepts due to inaccuracy and also fail to independently verify solutions, with conclusions often adapted from classmates. Low SRL students only reached the formulation stage and failed at the application and interpretation stages. These findings reinforce Zimmerman & Schunk's theory that SRL involves a cycle of planning, monitoring and self-evaluation.

Abstract

Concrete learning media are very important for children with special needs because they can improve understanding through visualization and engaging message delivery. Based on observations at Jember Special School Type C (Education and Care Centre), learning media are rarely used, especially when teaching integer material. This study aims to describe the process and outcomes of developing a pop-up book learning medium tailored to the different types of children with special needs, ensuring its validity, practicality, and effectiveness. The study employs a modified 4-D development model within a Research and Development (R&D) framework. Data were collected through validation sheets, user response questionnaires, interview guides, and learning outcome tests. Three methods of data analysis were used: validity analysis, practicality analysis, and effectiveness analysis. The validation results showed average scores of 3.67, 3.69, and 3.54 for learning media designed for students with intellectual disabilities, physical disabilities, and visual impairments, respectively, which are categorized as valid. The media were then tested on nine students at Jember Special School Type C, consisting of seven students with intellectual disabilities, one student with visual impairment, and one student with physical disability. Practicality analysis was conducted based on student and teacher response questionnaire scores, which were 80.25% and 80.75%, respectively, indicating a good level of practicality. The learning outcome test showed a 100% mastery level, indicating that the learning media met the criteria for effectiveness. This research is expected to serve as a reference for other researchers who wish to develop similar instructional media or further develop pop-up book learning media for other types of children with special needs. Media pembelajaran konkret sangat penting bagi anak berkebutuhan khusus karena dapat meningkatkan pemahaman mereka melalui visualisasi dan penyampaian pesan yang menarik. Berdasarkan observasi di SLB-C TPA (Taman Pendidikan dan Asuhan)  Jember, media pembelajaran jarang digunakan, terutama saat mengajarkan materi bilangan bulat. Penelitian ini bertujuan untuk mendeskripsikan proses dan hasil pengembangan pop -up book sebagai media pembelajaran berdasarkan jenis ABK yang valid, praktis, dan efektif. Penelitian ini menggunakan model pengembangan 4-D yang dimodifikasi dalam kerangka R&D. Pengumpulan data dilakukan melalui lembar validasi, angket respon pengguna, pedoman wawancara, dan tes hasil belajar. Terdapat tiga metode analisis data yaitu analisis kevalidan, analisis kepraktisan, dan analisis keefektifan. Hasil validasi menunjukkan skor rata-rata untuk media pembelajaran tunagrahita, tunadaksa, dan tunanetra sebesar 3,67; 3,69; dan 3,54 yang dikategorikan valid. Media tersebut kemudian diuji coba pada sembilan peserta didik di SLB-C TPA Jember, terdiri dari tujuh peserta didik tunagrahita, satu peserta didik tunanetra, dan satu peserta didik tunadaksa. Analisis kepraktisan dilakukan melalui skor angket respon siswa dan guru yang masing-masing sebesar 80,25% dan 80,75%, menunjukkan tingkat kepraktisan yang baik. Hasil Tes Hasil Belajar menunjukkan ketuntasan belajar sebesar 100%, yang menandakan media pembelajaran telah memenuhi kategori efektif. Penelitian ini diharapkan dapat dijadikan referensi bagi peneliti lain yang ingin mengembangkan media pembelajaran sejenis ataupun mengembangakn media pembelajaran pop-up book untuk anak berkebutuhan khusus lainnya.
