Abstract

The purpose of this study was to determine the improvement of the science learning outcomes of physics at the Gateway Team learning process. The research method used was classroom action research (CAR) with a qualitative approach. Based on the results of the study found that the completeness of student learning in the first cycle of 55.17% still did not reach the target. In the second cycle, there was an increase with 100% student completeness which means that it had reached the target. Based on observations of teacher activities and student activities, obtained an increase in learning. To observe teacher activity increased from 72.12% in the first cycle to 94.23% in the second cycle. And for the observation of student activity increased from 72.73% in the first cycle to 90.91% in the second cycle. Then the research can be concluded that the application of Team Gateway learning strategies can improve student learning outcomes because it is very useful to support student creativity in analyzing problems to improve student learning outcomes. Researchers suggest teachers should use the Gateway Team learning strategy because students interact with one another to strengthen the knowledge they have acquired and also require students to work together in groups to solve problems in the material so that student learning outcomes are better and teachers are advised to use index cards and learning resources in the form of textbooks that are support student activities.

Abstract

This research motivated by the problem academic talent, especially in science-physics subjects, because many students do not achieve minimum mastery in science-physics subjects. Research sub-focus 1) The performance of science-physics teachers at the BNKP Telukdalam Christian Private Junior High School. 2) The academic talent of the seventh grade physics subject. The type of research used is qualitative research with a phenomenological approach. The results showed that 1) The performance of the science-physics teachers was good, where the Guidance and Counseling teachers carried out their duties well according to the function of Guidance and Counseling services. 2) Grade VII students have IPA-Physics academic talent, where students try to solve difficult problems by asking the IPA-Physics subject teacher, and looking for reference sources on the internet that have the same IPA-physics questions. The conclusion of the research on the role of science-physics teachers in developing students' science academic talent by providing knowledge about talent, teachers providing insight into knowledge about their talents, it can open up students' views about their talents more broadly.

Abstract

This study aims to develop a contextual learning model for the topic of projectile motion by integrating Hombo Batu activities as a form of local wisdom from the South Nias community. Hombo Batu, or the traditional stone-jumping ritual, is a physical activity rich in two-dimensional kinematics elements, such as initial velocity, angle of elevation, and parabolic trajectory. The research employed the Research and Development (R&D) method based on Sugiyono's development model, which includes the following stages: identifying potential and problems, data collection, product design, validation, revision, and limited trials. Validation results from subject matter experts and media experts indicated that the developed learning model achieved a high level of validity (Aiken’s V > 0.85), categorized as “highly feasible.” A limited trial conducted with junior high school students in South Nias showed that the model effectively improved students' understanding of projectile motion, with an average N-Gain score of 0.56 (moderate to high category). Additionally, the implementation of the model led to increased learning motivation and greater appreciation of local culture among the students. This model not only enhances conceptual understanding in physics but also strengthens students’ character and cultural identity through a learning approach that is contextual, meaningful, and applicable. Therefore, the Hombo Batu-based contextual learning model is recommended as an innovative alternative for teaching physics, particularly in regions rich in local cultural values.

Abstract

This study aims to examine the utilization of the local wisdom embodied in the Nias Traditional House as a learning medium for creative economy among students at SMA Negeri 1 Teluk Dalam. Motivated by the need to integrate cultural values into the learning process to enhance students’ understanding and motivation, this research employs a descriptive qualitative approach with data collected through observation, interviews, and document studies. The findings reveal that using the Nias Traditional House as a learning medium significantly increases student engagement, strengthens their understanding of creative economy concepts, and fosters an entrepreneurial spirit rooted in local cultural values. Furthermore, integrating local wisdom into the learning process supports cultural preservation and encourages students’ creativity in developing innovative business ideas. The results also highlight the crucial role of teachers and traditional leaders in facilitating participatory and contextual learning. This study recommends the development of curricula and learning media that are more adaptive to local wisdom to support sustainable and regionally relevant education.

Abstract

The word Ya’ahowu is a distinctive greeting used by the people of Nias, carrying deep meaning and strong cultural values. This study aims to explore the meaning, function, and social significance of Ya’ahowu as a symbol of love and cultural identity within the Nias community. The research employs a literature review method, analyzing various sources such as journals, books, and scholarly articles related to the language and culture of Nias. The findings reveal that Ya’ahowu is not merely a simple salutation but embodies a prayer and well-wishes for the person being greeted. Its primary functions extend beyond social interaction, encompassing cultural and emotional roles that strengthen interpersonal relationships and foster social solidarity. Moreover, Ya’ahowu reflects core values such as affection, respect, and a strong spirit of brotherhood. In today’s modern context, this greeting remains relevant and holds potential as a symbol of cultural diplomacy and a tool for preserving the local language. In conclusion, Ya’ahowu is an important intangible cultural heritage that must be preserved. It serves not only as a means of communication but also as a representation of the unique values of love and peace inherent to the Nias people.

Abstract

Mathematics learning is often perceived by students as difficult and abstract, leading to dependence on teacher guidance and hindering the development of independent learning. This study examines the role of local wisdom as a means to build independence in mathematics learning, specifically at SMA Negeri 1 Teluk Dalam, South Nias. Through a literature review, it was found that integrating local values and culture into the mathematics learning process not only enhances conceptual understanding contextually but also motivates students to learn independently. Local wisdom, such as geometric patterns in traditional weaving, indigenous life philosophies, and traditional building structures, can serve as relevant and engaging learning media for students. This approach helps students develop critical and creative thinking skills while boosting their confidence in solving mathematical problems. Furthermore, learning based on local wisdom strengthens students’ cultural identity and fosters pride in their local heritage. This study recommends the development of learning modules that integrate local wisdom and teacher training as efforts to optimally support students’ independent learning. The implications of this review suggest that local wisdom can be an effective strategy to improve the quality of mathematics education and the development of students’ independent character within the school environment.
