Abstract

The advancement of digital technology has transformed various aspects of life, including education. In mathematics education, technology offers numerous opportunities to enhance the effectiveness of learning but also presents significant challenges. This paper aims to evaluate mathematics learning in the digital era, focusing on the challenges and opportunities involved. This study employs a literature review method with descriptive analysis of relevant studies. Digital technology has great potential to improve accessibility, personalization, and interactivity in mathematics learning. Through technology-based learning platforms, students can access materials that were previously difficult to reach, visualize abstract concepts, and engage in independent and collaborative learning. Additionally, adaptive algorithms and artificial intelligence provide personalized learning experiences that can improve student outcomes. However, several challenges also arise, including digital inequality, limited teacher competence, curriculum adaptation, and the risk of over-reliance on technology, which may hinder students' deep understanding of basic mathematical concepts. To optimize these opportunities, synergy among technology, educators, and educational policies is essential. Thus, this paper provides insights into strategic steps to enhance the quality of mathematics learning in the digital era while addressing the existing challenges.

Abstract

The objective of this socialization is to provide an overview of the application of artificial intelligence in dealing with problems related to bullying. The positive effects of artificial intelligence on the life and growth of today's children will be widely utilized. At an early age, the protection of artificial intelligence is indispensable. It can play a role in preventing extreme behavior from developing in children. Post-bullying, the counseling program can be developed as part of parental counseling for their children's mental health. Additionally, an early warning function should be deployed, and permanent protection must be added to artificial intelligence. Among them, enhancing children's ability to judge, guide, and respond in events involving negative energy is essential. The results showed recent advancements in AI technology offer significant potential for more effective outcomes compared to traditional non-technological approaches in preventing and addressing children's bullying. These AI-driven solutions could potentially reduce the occurrence of bullying incidents, lessen their impact on children, and provide better protection for victims. Interactive video games that incorporate physical activities are now combining various elements such as muscle group engagement, body awareness, head-torso coordination, and social cooperation into comprehensive exercise packages. AI-enhanced video games can identify motivations behind bullying behavior in children by analyzing audio-visual data, assigning different levels of credibility to the information gathered during gameplay. These games are capable of providing immediate assistance when bullying attempts are detected, such as by playing calming music and animations, or by initiating mentoring sessions and discussions about appropriate behavior.

Abstract

Dari hasil nilai rata-rata siswa yang semula 53 dan setelah diberlakukan Media Audio Visual naik menjadi 82. Hasil perhitungan dengan tes diperoleh thitung sebesar 19,040 yang kemudian dibandingkan dengan ttabel sebesar 1,797 dengan df=29 dan taraf signifikan 0,05. Jika thitung > ttebel maka Ho ditolak dan Ha diterima, dan jika thitung > ttabel maka Ho diterima dan Ha ditolak. Berdasarkan data ternyata thitung > ttabel(19,040 > 1,797) pada perhitungan uji beda mean hasil belajar dengan menggunakan test. Dengan demikian dapat dinyatakan bahwa skor mengalami peningkatan hasil belajar siswa signifikan sehingga Ha hasil belajar diterima. Kriteria pengujiannya adalah hipotesis Ho diterima dan Ha ditolak jika thitung > ttabel Sebaliknya, hipotetis Ho ditolak dan Ha diterima jika nilai thitung > ttabel, artinya ada pengaruh terhadap media audio visual.

Abstract

Improving writing skills is as supporting factor for the success of learning carried out by each teacher. Writing ability comes from the habit of reading and analyzing problems in learning that is carried out every day. The culture of writing is still far from being a habit for teachers of SMP Negeri 3 Jorlang Hataran. Therefore, the University of HKBP Nommensen Pematangsiantar University team has carried out a community service at SMP Negeri 3 Jorlang Hataran, Jalan Besar Parapat, Nagori Bah Sampuran. district Jorlang Hataran, Simalungun Regency, North Sumatra where this service aims to socialize methods of improving English literacy skills using the problem based learning method for teachers of SMP Negeri 3 Jorlang Hataran. This service has been received with good response and was appreciated by the Principal of SMP Negeri 3 Jorlang Hataran. The results obtained from this service were 76.7% of participants who stated that they were satisfied with this service. It is hoped that with this activity, there will be a good cooperation established between the University and the school to develop the quality of teachers in order to create the higher quality education.

Abstract

Purpose: This research investigates how high school students approach three-dimensional geometry problems by considering differences in cognitive styles (impulsive and reflective) and levels of mathematical ability. The aim is to understand the variations in problem-solving strategies based on Polya’s stages, which include understanding the problem, planning, executing, and reviewing the solution. Method: A descriptive qualitative method was used with a comparative case study design. Four students were selected through purposive sampling, each representing a unique combination of cognitive style and mathematical ability. Data collection involved problem-solving tests and semi-structured interviews. The analysis focused on tracing the students’ reasoning and decision-making processes throughout each stage of problem solving. Findings: The results show that students with a reflective cognitive style tend to be more thorough when planning and reviewing their work. Impulsive students, on the other hand, often rush through the process, resulting in errors, although those with high mathematical ability can still demonstrate effective strategies and occasionally correct their mistakes. Students with stronger mathematical ability generally show better visualization, abstraction, and accuracy in applying geometric concepts. Significance: These findings suggest the need for instructional strategies that are sensitive to students’ cognitive profiles. Teaching approaches that emphasize structured reflection and scaffolding may enhance geometry learning outcomes, especially for students who tend to act impulsively.
