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 research uses a quantitative approach with a quasi-experimental method. The population this study all VII grade students SMP Negeri 2 Fanayama. The sample this study was class VII-A with a total of 22 students and class VII-B with a total of 24 students. The instrument used was a test of learning outcomes divided into two, namely the initial test and the final test. Based on the results of data processing that has been carried out and the calculation of the hypothesis test obtained tcount = 2.898 ttable = 1.68, then Ho is rejected and Ha accepted it can be concluded that there is a difference in the improvement of student learning outcomes using the Think Talk Write (TTW) learning model with the Time learning model Token then the results the Think Talk Write (TTW) learning model are more favored because this learning model can encourage students to develop and develop the ability to understand the physics material being taught and then write down the core of the material so that students can formulate the knowledge acquired in the language itself compared to the Time Token learning model

Abstract

This study aims to analyze the preservation of the Hombo Batu tradition in relation to the attitudes and interests of students at SMA Negeri 1 Teluk Dalam, South Nias Regency. The study employed a quantitative approach with a correlational descriptive method. The population consisted of all students at SMA Negeri 1 Teluk Dalam, with a sample of 120 students selected through proportional random sampling. Data were collected using a Likert-scale questionnaire, which was first tested for validity and reliability. The data were analyzed using descriptive statistics, Pearson correlation, and multiple linear regression. The results indicate that most students have a positive attitude (mean = 3.85) and a high level of interest (mean = 3.78) toward the Hombo Batu tradition. Both attitude and interest variables showed a significant positive correlation with tradition preservation, with correlation coefficients of r = 0.62 and r = 0.57, respectively (p < 0.05). Multiple linear regression analysis revealed that 56% of the variance in tradition preservation can be explained by students’ attitudes and interests, with attitude contributing more strongly than interest. These findings confirm that positive attitudes and high interest are key psychological factors in promoting students’ active involvement in local cultural preservation. Based on these results, it is recommended that schools and communities implement education programs based on local cultural values and extracurricular activities that foster students’ positive attitudes and interest in the Hombo Batu tradition, thereby ensuring the sustainability of this cultural heritage among younger generations.

Abstract

This study aims to determine whether there is a positive and significant relationship and there is an influence between learning interest on Integrated Science learning outcomes. The type of research used in this research is quantitative research with correlational methods. The population in this study were all 65 students of class VII at SMP Negeri 4 Maniamolo. The sampling technique uses a total sampling technique, meaning that the entire population is used as a sample. The instrument in this study used a closed questionnaire and students' science learning outcomes were in the form of odd semester final exam scores. Data analysis techniques were carried out by describing the data, correlational analysis, coefficient of determination and hypothesis testing. The test results in this study indicate that there is a positive and significant relationship between learning interest on science learning outcomes, and there is also an influence between learning interest on Integrated Science learning outcomes. So it was concluded that 1) because students have a sense of pleasure, interest, and a high desire for learning which is seen as giving them benefits and satisfaction, 2) students have a sense of comfort, are aware of the benefits of learning, and know the learning goals that make them interested so that learning occurs. improvement in learning outcomes.

Abstract

This study aims to examine the effectiveness of the implementation of the Problem Based Learning (PBL) model based on the local wisdom of Hombo Batu in improving students’ physics problem-solving abilities at SMA Negeri 1 Fanayama. The research employed a quasi-experimental method with a pretest–posttest control group design. The participants consisted of tenth-grade students who were divided into an experimental class and a control class. The experimental class received instruction using the Problem Based Learning model integrated with the cultural context of Hombo Batu, while the control class was taught using conventional learning methods. Data were collected through a physics problem-solving test administered before and after the learning process. The results showed that students in the experimental class experienced a significant improvement in their problem-solving abilities compared to those in the control class. The normalized gain score of the experimental group was higher than that of the control group, indicating that the implementation of the PBL model provided a more effective learning experience. In addition, integrating the Hombo Batu cultural context helped students understand physics concepts more meaningfully because the learning materials were related to real-life cultural practices familiar to the students. Therefore, the integration of Problem Based Learning with local wisdom can create contextual and meaningful physics learning while also fostering students’ appreciation of local cultural heritage.
