Faishal abdurrasyid — 2025-07-14

Abstract: This study aims to describe the creativity in utilizing Visual basic for applications (VBA) in PowerPoint as a learning media among students in the Mathematics Education program. The research method used is descriptive with a qualitative approach. The study was conducted in the Mathematics Workshop Room at the Mathematics Education program, Mandalika University of Education. The subjects of this study were 6 randomly selected students. The instruments used in the research consisted of 6 questions covering the experience of using VBA in PowerPoint for learning, the benefits of VBA, and the students' interest in VBA. Data collection techniques included observational interviews and observation of the VBA products created, which were then compared with those made by the researcher. The data analysis techniques employed were coding and thematic analysis, derived from interview results and the comparison of student products with the researcher's product. The results indicated that three participants, S1, S2, and S3, were unable to create VBA in PowerPoint correctly, mainly due to errors in writing the code in the VBA worksheet, resulting in non-functional outcomes. Two participants, S4 and S5, successfully executed VBA correctly. One participant, S6, not only successfully executed VBA but also managed to develop it further. Based on these findings, subjects S1, S2, and S3 were categorized as having low creativity due to their inability to execute VBA in PowerPoint. Subjects S4 and S5 were categorized as having moderate creativity, as they could execute VBA in PowerPoint. Subject S6 was categorized as having high creativity, as they were able to execute and further develop VBA in PowerPoint.

Pengaruh Model Pembelajaran Problem Based learning terhadap Literasi Matematika Siswa SMAN 1 Lembar

Sri Hidayatullah — 2025-07-14

The purpose of this study was to determine the effect of problem-based learning model on mathematical literacy of students of SMAN 1 Lembar. The method used in this research is quasi experimental method with Pretest-Posttest Control Group Design research design. The subjects of this research were students of class X SMAN 1 Lembar. The samples used in this study were two classes where class X 1 as the experimental class and X 2 as the control class, then the two classes were given different treatments, namely the experimental class was given treatment with a problem-based learning model while the control class was given a conventional learning model (lecture). After being given treatment, in the form of a pre-test, then a posttest is given to determine the final ability of students. The instrument used in this study is to use a test consisting of 3 essay-shaped questions. The analysis technique used is using t-test statistical analysis with the help of SPSS 25. From the results of the hypothesis test the sig value. (2-tailed) 0.000 <0.05 then H0 is rejected and H1 is accepted. So it can be concluded that there is an effect of problem-based learning model on students' mathematical literacy.

Lu'luin Najwa — 2025-07-12

This study aims to describe the academic supervision strategies employed by the principal in developing teacher professionalism at SMAN 1 Labuapi. The research uses a qualitative approach with a case study method. Data were collected through in-depth interviews, observations, and documentation. The research informants consisted of the principal, teachers, and the vice principal for academic affairs, selected through purposive sampling. Data analysis was conducted using the interactive analysis model developed by Miles and Huberman, which includes data reduction, data display, and conclusion drawing. The findings indicate that the principal implements various academic supervision strategies, including individual supervision, classical supervision, group supervision, and reflective supervision. These strategies contribute positively to enhancing teacher professionalism, particularly in pedagogical, professional, social, and personal competencies. The challenges encountered in implementing academic supervision include limited time, varying levels of teacher preparedness, and a lack of optimal follow-up after supervision activities. The principal addresses these challenges by involving the school management team, prioritizing supervision based on teacher needs, and recognizing high-performing teachers with awards. This study concludes that well-planned, systematic, and collaborative academic supervision can effectively improve teacher professionalism. It is recommended that principals continue to develop innovative academic supervision models to foster a culture of quality learning in schools.

Agusfianuddin Agusfian — 2025-07-14

Siswa di sekolah dasar masih mengalami kesulitan dalam menyelesaikan soal cerita matematika. Kesulitan siswa terletak pada memahami bahasa matematis dalam soal cerita. Tujuan penelitian ini adalah melakukan analisis faktor-faktor kesulitan siswa memehami kata matematis dalam bahasa soal cerita di sekolah dasar. Jenis penelitian adalah deskriptif kualitatif dengan desain studi kasus. Subjek penelitian, siswa kelas tinggi di sekolah dasar di Kabupaten Sumbawa sebanyak 100 siswa. Sedangkan, pengambilan sampel menggunakan teknik purposive sampling. Teknik pengumpulan data, yaitu triangulasi sumber data melalui tes, wawancara dan kuisioner. Teknik analisis data secara deskriptif kualitatif. Hasil penelitian menemukan faktor-faktor yang mempengaruhi kesulitan siswa dalam bahasa matematis pada penyelesaian soal cerita di sekolah dasar, yaitu karena faktor internal dan eksternal.Faktor internal antara lain: (1) kesulitan memahami dan menerjemahkan kosakata dalam soal, (2) kesulitan menerapkan konsep, prosedur dan penalaran, dan (3) siswa tidak teliti, melakukan tebakan jawaban dan kesulitan soal yang panjang. Sedangkan faktor eksternal, antara lain: (1) guru jarang memberikan soal cerita kepada siswa; (2) lingkungan sekolah yang kurang mendukung tumbuhnya literasi siswa; (3) tidak ada model pembelajaran untuk mendukung siswa memeiliki kemampuan bahasa matematis; dan (4) kurangnya dorongan orang tua untuk mendukung siswa dalam belajar. Temuan ini dapat menjadi bahan refleksi bagi guru, sekolah, dan orang tua. Dengan adanya pemahaman ini, semua pihak dapat lebih proaktif dalam menciptakan lingkungan belajar yang kondusif dan strategi pembelajaran yang tepat. Harapannya, siswa dapat meningkatkan kemampuan bahasa matematis dan keterampilan berpikir logis dalam menyelesaikan soal cerita secara efektif.
