Abstract

Students with special needs, including those with speech impairments, often face challenges in learning mathematics and therefore require specialised strategies, such as scaffolding, to enhance their mathematical understanding. This study aimed to examine how scaffolding strategies support students with speech impairments in overcoming difficulties in learning mathematics in a special school setting. This qualitative case study involved one teacher and five students with speech impairments, selected through purposive sampling. Data were collected through observations, tests, interviews, and audio and video recordings. Data analysis was conducted in three stages: data reduction, data display, and conclusion drawing and verification. The findings show that the teacher’s scaffolding aligned with six aspects of the Mäkinen and Mäkinen framework: activation, presence, sensitivity, assistance, trust, and autonomy. Activation and assistance were the most strongly associated with improved conceptual understanding. The students demonstrated the ability to define, represent, and calculate the perimeter of squares and rectangles. Visual aids, concrete objects, and multimodal communication (oral, gestural, and sign language) enhanced understanding. Integrating visual, kinesthetic, and nonverbal strategies provides meaningful support for students with speech impairments, and the six-dimensional scaffolding framework serves as a practical guide for inclusive instructional design.

Abstract

Aceh is one of 34 provinces in Indonesia that has a local education goal, that is, the education is implemented based on Islamic values. The integration of Islamic values into mathematics learning can be implemented by using learning media. This research is an early phase of developmental research. The purpose of this study was to investigate teachers’ perceptions of the integration of Islamic values ​​into mathematics learning through comics. The participants were 40 junior high school mathematics teachers in Banda Aceh who join the PMRI workshop. Data were collected through an open-ended questionnaire consisting of 11 questions and then analyzed descriptively. The results showed that teachers (87.5%) believed that Islamic values and mathematics ​​are integrated; moreover, mathematics teachers and religion teachers play a major role in teaching Islamic values. The majority of teachers (95%) believed that the knowledge of Islamic values influences the way they teach. However, more than half of teachers (62.5%) had never attended a workshop or seminar, or read articles that discuss the integration of Islamic values ​​into mathematics learning through comics. The result of the study also showed that the mathematics comics in Islamic values were limited. Therefore, it is necessary to develop mathematics comics in Islamic values contexts.

Abstract

Penelitian ini membahas tentang simulasi kontrol optimal model dinamik perokok dengan melibatkan harga dan parameter fungsi dampak kenaikan harga. Pengaruh harga rokok terhadap pengurangan konsumsi rokok ditinjau melalui dua kasus yang berbeda yaitu kasus dengan fungsi dampak kenaikan harga secara linear dan logaritmik. Adapun tujuan dari penelitian ini yaitu mengembangkan model jumlah perokok dengan melibatkan harga rokok dan mendapatkan solusi optimum pada model jumlah perokok dengan meminimumkan jumlah perokok berat dan perokok kadang-kadang melalui kenaikan harga rokok. Model yang digunakan yaitu model jumlah perokok dengan dinamika akar kuadrat yang terdiri dari empat kompartemen, yakni perokok potensial (), perokok kadang-kadang (), perokok berat () dan mantan perokok (). Model ini menggunakan interaksi antara perokok potensial dan perokok berat dengan melibatkan harga rokok. Model dinamik perokok dengan fungsi kenaikan harga secara logaritmik lebih baik dalam mempertahan perokok berat dari pada model dengan fungsi linear, sedangkan model dinamik perokok dengan fungsi linear lebih cepat dalam menurunkan jumlah perokok berat daripada fungsi logarithmic. Kenaikan harga yang ideal untuk menurunkan jumlah perokok di Indonesia adalah 66,67%.

Abstract

Illicit drug use is controlled by prevention and treatment. LH Model is the first model of illicit drug use which has been improved for over ten years. In 2012, estimated about 324 million people or about seven percent of the world's population are drug illicit drug users and 183,000 of them die per year because of illicit drug use worldwide and 12.044 people die each year in Indonesia, but there was no death in the LH Model. In this study the model is extended by adding a state of death (D) which forming LHD model. LHD model is fitted with the illicit drug user data of BNN by selecting parameter values that approach the tendencies of the data, after that LHD model is simulated by minimizing the budget for prevention and treatment. Prevention is dominant on unrestricted budget, while treatment is dominant on restricted budget.

Abstract

[English]: Understanding students' difficulties in solving mathematics problems is crucial for effective teaching. This study aims to determine the ability of prospective mathematics teachers to analyze students' work in solving PISA problems and identify the types of assistance recommended to overcome students' difficulties. Using a descriptive qualitative design within a case study framework, the research subjects consisted of two prospective mathematics teachers from a university in Aceh, who had good knowledge in answering PISA problems. Data was collected through written tests, interview, and documentation of analysis results for student answers. This study was conducted in two stages: (1) the subjects analyzed, assessed, and recommended assistance for students' work, and (2) the researcher evaluated the results of the analysis and the appropriateness of the assistance proposed by the subjects. The findings indicate that varying Pedagogical Content Knowledge (PCK) abilities of teachers can affect the accuracy of the analysis and the effectiveness of the recommended assistance. Subjects with high PCK can analyze students' work and suggest assistance appropriately. In contrast, subjects with low PCK only analyze and provide suggestions to overcome students' difficulties in general. This study emphasizes the importance of integrating content knowledge and pedagogy in preparing prospective teachers. [Bahasa]: Memahami kesulitan siswa dalam memecahkan masalah matematika sangat penting untuk pengajaran yang efektif.

Dengan menggunakan pendekatan deskriptif kualitatif dengan jenis case study, subjek penelitian terdiri dari dua orang calon guru matematika dari salah satu universitas di Aceh, yang memiliki pengetahuan yang baik dalam menjawab soal-soal PISA. Data dikumpulkan melalui tes tertulis, wawancara, dan dokumentasi hasil analisis untuk jawaban siswa. Penelitian ini dilakukan dalam dua tahap: (1) subjek menganalisis, menilai, dan merekomendasikan bantuan untuk hasil kerja siswa; dan (2) peneliti mengevaluasi hasil analisis dan kesesuaian bantuan yang diusulkan subjek. Temuan menunjukkan bahwa kemampuan Pedagogical Content Knowledge (PCK) guru yang bervariasi dapat mempengaruhi ketepatan analisis dan efektivitas bantuan yang direkomendasikan. Subjek dengan PCK yang tinggi dapat menganalisis hasil kerja siswa dan menyarankan bantuan dengan tepat. Sebaliknya, Subjek dengan PCK yang rendah hanya menganalisis dan memberikan saran untuk mengatasi kesulitan siswa secara umum. Studi ini menekankan pentingnya mengintegrasikan pengetahuan konten dan pedagogi dalam mempersiapan calon guru.
