Abstract

Limit fungsi merupakan salah satu konsep dalam matematika yang memerlukan perhatian khusus. Terdapat banyak konsep matematika yang memerlukan pemahaman konsep limit dengan baik. Konsep limit fungsi merupakan materi yang akan diajarkan oleh calon guru matematika kepada siswa di kelas 11, sehingga perlu bagi calon guru matematika untuk menguasai konsep tersebut. Namun, ditemukan masih terdapat calon guru matematika yang belum menguasai konsep tersebut. Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk mendeskripsikan kesalahan mahasiswa calon guru matematika dalam menyelesaikan soal limit fungsi dan penyebabnya. Penelitian dilakukan di salah satu universitas di Provinsi Sulawesi Selatan dengan 3 subjek yang berada di semester 4 jenjang S1 prodi pendidikan matematika. Analisis yang dilakukan diadaptasi dari langkah-langkah analisis kesalahan oleh Medova (2019). Hasil yang ditemukan adalah kesalahan yang cenderung dilakukan oleh mahasiswa adalah kesalahan dalam membuat sketsa grafik fungsi dan kesalahan dalam memvisualisasikan limit fungsi. Kesalahan dalam membuat sketsa grafik fungsi tersebut dapat ditemukan saat mahasiswa tidak mampu mensketsa grafik fungsi yang terdapat suatu titik tidak terdefinisi dalam domainnya. Adapun kesalahan dalam memvisualisasikan limit fungsi terlihat saat mahasiswa tidak mampu menunjukkan ketiadaan limit di suatu titik. Kesalahan-kesalahan tersebut disebabkan karena subjek yang terpilih belum memahami dengan baik konsep fungsi dan konsep limit fungsi.

Abstract

Penelitian ini menganalisis tantangan siswa dalam belajar matematika dari perspektif gaya kognitif field-dependent (FD) dan field-independent (FI). Penelitian sebelumnya telah menunjukkan bahwa gaya kognitif siswa mempengaruhi pemahaman dan kinerja siswa dalam matematika. Namun, pemahaman yang komprehensif tentang jenis kesalahan umum dan faktor-faktor yang mempengaruhinya masih kurang, meskipun penyelidikan sebelumnya tentang hubungan antara gaya kognitif FD dan FI dan pemahaman matematika siswa. Penelitian ini menggunakan pendekatan deskriptif kualitatif dan dilaksanakan di kelas VIII salah satu SMP di Kabupaten Sidrap. Pengumpulan data menggunakan instrumen GEFT, tes matematika, dan wawancara. Keabsahan data dilakukan dengan triangulasi metode. Temuan menunjukkan bahwa siswa dengan gaya kognitif FD cenderung mengandalkan konteks eksternal, fokus pada detail dan informasi spesifik, dan memerlukan instruksi yang jelas untuk memproses informasi matematika. Di sisi lain, siswa dengan gaya kognitif FI cenderung melepaskan diri dari konteks eksternal, fokus pada konsep dan prinsip, serta memiliki kemampuan kerja yang mandiri. Kesalahan yang dilakukan oleh siswa dengan gaya kognitif FD dan FI dapat dikaitkan dengan faktor-faktor seperti ketergantungan pada konteks eksternal, kurangnya pemahaman konsep matematika, dan kurangnya pemahaman prosedur operasi matematika yang benar.

Abstract

The Unconscious Mind Program (UMP) is an approach that can use to improve student learning outcomes by incorporating suggestions into students' subconscious minds. The teachers use structured relaxation, attractive visual images, metaphors, movements, music, and suggestions in UMP learning. This study aims to determine the motivation and ability of teachers to implement UMP learning. This research is a type of CAR using 15 teacher subjects at SMPN Bantaeng. This research was conducted in two cycles, each of consisted of planning, implementation, observation, and reflection stages. The result is that the dominant teacher has been able to apply the UMP, although there are still a small number of teachers who are only able to apply 75% of the overall UMP implementation indicators. The application of UMP can make teachers' motivation high in carrying out learning in the classroom with an average motivation score of 3.61 from a maximum score of 4.00.

Abstract

This study highlights the importance of accuracy in identifying students’ learning difficulties and designing effective guidance services in schools. Findings reveal that internal factors such as low motivation, academic anxiety, and cognitive differences, along with external factors including family support, teaching methods, and limited school facilities, significantly contribute to academic barriers. Accurate diagnosis of learning difficulties through observation, interviews, and diagnostic instruments enables interventions tailored to students’ needs. Furthermore, the analysis of guidance program design emphasizes that services based on students’ actual needs can enhance motivation, foster positive character development, and strengthen social skills. These findings underline the necessity of a holistic approach and supportive educational systems to optimize students’ academic potential and personal growth

Abstract

Learning problems among students at school remain a challenge in the educational process, such as difficulties in understanding learning materials, low learning motivation, and a lack of learning independence. These conditions require the presence of guidance services that are able to assist students in overcoming learning obstacles in a systematic manner. This study aims to identify effective forms of learning guidance and analyze the role of guidance organizations in schools in supporting students’ learning success. The research method used in this study is a literature review by examining various relevant sources, including books and scientific journal articles related to learning guidance and guidance organizations in schools. The results of the study indicate that effective learning guidance includes individual guidance, group guidance, learning assistance, as well as remedial and enrichment services. In addition, the success of learning guidance is strongly influenced by the role of well-coordinated guidance organizations involving guidance and counseling teachers, homeroom teachers, subject teachers, school principals, and parents. Synergy among these elements enhances the effectiveness of learning guidance services, improves students’ academic achievement, and creates a supportive learning environment. Therefore, well-planned learning guidance supported by a strong guidance organization plays an important role in improving the quality of learning processes and outcomes in schools
