Abstract

The industrial revolution 4.0 is a formidable challenge for the world of education, one of which is learning mathematics. Moreover, in the current Covid-19 condition, which requires that learning be carried out by e-learning, the level of students' mathematical problem solving abilities is getting lower. To overcome this problem, this study applied an IT-based learning model (geogebra). The objectives of this research are to know the improvement of students' mathematical problem solving, the improvement of students' mathematical learning activities, and the improvement of the teacher's ability to manage learning. This type of research is Classroom Research. The analytical technique used is descriptive. The results of this study seen from the results of students' mathematical problem solving tests increased by 33.33%. Student activity in learning increased by 23.43%. The ability of teachers to manage learning increased by 36%. So the results of this study show that the IT-based learning model (geogebra) can improve students' mathematical problem solving, student activities in class X Multimedia I SMK Negeri 4 Padangsidimpuan.

Abstract

Tujuaan penelitian ini adalah Pengembangkan E–LKPD berbasis model PBL (Problem Based Learning) untuk meningkatkan kemampuan komunikasi matematis pada materi aljabar. Penelitian ini menerapkan jenis penelitian pengembangan ADDIE. E–LKPD diuji cobakan di SMP Swasta Muhammadiyah 29 Padangsidimpuan pada kelas VII. Instrumen yang digunakan merupakan penilaian dari ahli materi dan media, respon peserta didik terhadap produk menggunakan angket kebergunaan, dan hasil pengerjaan E–LKPD. Aktivitas pembelajaran dalam E–LKPD disesuaikan dengan sintak PBL dan indikator kemampuan komunikasi matematis. Hasil dari penelitian ini pada tahap pengembangan, produk dikembangkan dan diuji melalui validasi ahli materi dan media, diperoleh nilai rata-rata validasi yaitu 86,33% berdasarkan aspek kelayakan materi 77,5%, kelayakan penyajian 88%, kelayakan keterbacaan 90%, kelayakan kebahasaan 87,5%, aspek komunikasi matematis dan aspek langkah PBL 87,5%. Hasil  Respon siswa menggunakan angket kebergunaan menunjukkan bahwa rata-rata untuk masing masing aspek adalah 3,11 (usefulness), 3,12 (ease of use), 3,25 (ease of learn), dan 3.00 (satisfaction) dengan skala maksimum 4. Rata-rata untuk semua kategori adalah 3,12 yang berati bahwa aplikasi ini praktis untuk digunakan. Dan untuk hasil efektifitas diperoleh hasil ketuntasan belajar siswa sebesar 71,43% dengan kategori baik, Sehingga E-LKPD berbasis model Problem Based Learning layak digunakan dan efektif untuk meningkatkan komunikasi matematis siswa

Abstract

Confidence is the capital that is owned by every individual in an effort to actualize themselves, one of the factors that influence self-confidence is height. The purpose of this study was to find out whether height has an influence on self-confidence. This research method is descriptive quantitative. The population in this study were 266 students of the Communication Studies Program at Mercu Buana University, Yogyakarta, with a sample of 116 respondents using a probability sampling technique. The instruments used in this study were height indicators and self-confidence questionnaires based on Lauster's theory (2012). The data obtained were then analyzed using the Pearson’s technique. The results of the study found that most of the respondents had low self-confidence, namely 50.9% and had above average height, namely 68.1%. The results of the regression analysis obtained a significance value of 0.002 (p <0.05) and an r square of 8.1% which indicates that there is an effect of height on self-confidence. In conclusion, there is an effect of height on self-confidence of 8.1%, while 90.9% is influenced by other variables. Suggestions for future researchers are to be able to follow up on other variables that affect self-confidence.

Abstract

This research aims to improve student learning outcomes in Islamic religious education learning using audiovisual. This research is a classroom action research that uses four steps, namely planning, action, observation and reflection. The subject of this research is elementary school students. The data of this study was obtained by test and observation techniques. Tests are used to measure learning outcomes and observations are used to analyze the learning activities of teachers and students. The data analysis technique used in this study is descriptive statistics by comparing the results obtained with research success indicators. The results of the study show that audiovisual can improve student learning outcomes in Islamic religious education learning. This can be seen from the increase in the percentage of student learning completeness in each cycle with details of 40.19% in the pre-cycle, 64.37% in the first cycle and 88.72% in the second cycle. Thus, the use of audiovisual can be used as an alternative to improve student learning outcomes in Islamic religious education learning.

Abstract

This study aims to describe and analyze bullying behavior that occurs within the school environment, particularly at the junior high school level (SMP), focusing on the forms of bullying, its causal factors, and its impact on the students involved, both perpetrators and victims. The research adopts a qualitative case study method, employing data collection techniques such as direct observation, in-depth interviews, and documentation at a public school. The findings reveal that bullying manifests in physical forms (hitting, kicking), verbal abuse (mockery, insults), and psychological harm (exclusion, intimidation). Contributing factors include dysfunctional family environments, peer pressure, and weak supervision from the school. The impacts are significant, ranging from emotional disturbances and decreased learning motivation to poor academic performance and social withdrawal. This study recommends the importance of active collaboration among teachers, parents, and schools in preventing and addressing bullying comprehensively, as well as in creating a safe, inclusive, and supportive school climate for students’ holistic development.
