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

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.

Abstract

Kemampuan berpikir kritis merupakan kompetensi penting yang harus dimiliki mahasiswa, khususnya calon guru matematika. Namun, berbagai penelitian menunjukkan bahwa kemampuan berpikir kritis mahasiswa masih rendah, terutama dalam menentukan strategi pemecahan masalah. Salah satu upaya untuk meningkatkannya adalah melalui penerapan model pembelajaran yang tepat serta pengembangan perangkat pembelajaran inovatif. Penelitian ini bertujuan mengembangkan E-LKM berbasis inquiry learning yang berorientasi pada kemampuan berpikir kritis pada mata kuliah Teori Bilangan di Program Studi Pendidikan Matematika Universitas Mercu Buana Yogyakarta (UMBY), serta menguji kelayakannya dari aspek validitas, kepraktisan, dan keefektifan. Penelitian ini merupakan penelitian pengembangan dengan model ADDIE yang meliputi tahap Analysis, Design, Development, Implementation, dan Evaluation. E-LKM dikembangkan menggunakan Flip PDF Professional, PowerPoint, dan Canva. Uji validitas dilakukan oleh ahli media dan ahli materi, kepraktisan diukur melalui angket respon mahasiswa pada kelompok kecil dan besar, sedangkan keefektifan ditinjau dari respon mahasiswa dan hasil posttest. Hasil penelitian menunjukkan bahwa E-LKM yang dikembangkan valid berdasarkan penilaian para ahli, praktis berdasarkan respon mahasiswa dengan skor tertinggi pada aspek kemudahan penggunaan, serta efektif dengan tingkat ketuntasan belajar mencapai 100%, di mana seluruh mahasiswa memperoleh nilai di atas C+. Dengan demikian, E-LKM berbasis inquiry learning berorientasi pada kemampuan berpikir kritis dinyatakan valid, praktis, dan efektif serta layak digunakan sebagai perangkat pembelajaran inovatif di perguruan tinggi. Critical thinking skills are essential competencies for university students, particularly prospective mathematics teachers. However, previous studies indicate that students’ critical thinking abilities remain low, especially in determining appropriate problem-solving strategies. One way to improve these skills is through the implementation of appropriate learning models and the development of innovative learning materials. This study aims to develop an inquiry learning-based electronic student worksheet (E-LKM) oriented toward critical thinking skills in the Number Theory course at Universitas Mercu Buana Yogyakarta (UMBY) and to examine its feasibility in terms of validity, practicality, and effectiveness. This research employed a development method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The E-LKM was developed using Flip PDF Professional, PowerPoint, and Canva. Validity was evaluated by media and material experts, practicality was measured through student response questionnaires in small and large groups, and effectiveness was assessed through student responses and posttest results. The findings indicate that the developed E-LKM is valid based on expert judgment, practical according to student responses with the highest score on ease of use, and effective with a 100% learning mastery rate, where all students achieved grades above C+. Therefore, the inquiry learning-based E-LKM oriented toward critical thinking skills is valid, practical, and effective for use as an innovative learning tool in higher education.
