The research subjects consisted of 103 students in grade XI of SMK Mutiara Qolbu Cianjur which were divided into three classes. Data collection techniques were carried out through observation, interviews, questionnaires, expert validation, and news text writing tests. Data were analyzed using quantitative and qualitative descriptive techniques. The results of the study show that audio-visual learning media based on the Discovery Learning model obtained a very good feasibility level based on the results of the validation of material experts with a percentage of 91% and the validation of media experts of 89%. The results of the trial showed that the learning media received a positive response from students with an average percentage of 87.25%. In addition, the use of Discovery Learning-based audio-visual learning media has proven to be effective in improving students' ability to write news texts. This is shown by the increase in the average score of students from 64.21 in the pre-test to 84.37 in the post-test. The use of audio-visual media also improves students' learning activities, such as active questioning, discussion participation, and the ability to identify news elements.

This study aims to analyze the strategies employed by madrasah principals to enhance teacher professionalism through the implementation of managerial functions, academic supervision, entrepreneurship, and socio-spiritual leadership at MAN 1 Bandung and MAN 2 Bandung. The study employs a qualitative approach using a descriptive case study method. Data collection techniques included in-depth interviews, participatory observation, and document analysis, while data analysis was conducted using the Miles and Huberman model through the stages of data reduction, data presentation, and drawing conclusions. The research findings indicate that strategies for enhancing teacher professionalism begin with needs-based planning, followed by strengthening clinical academic supervision, fostering a collaborative and innovative work culture, and implementing continuous evaluation. The implementation of these strategies has a positive impact on improving teachers’ pedagogical and professional competencies, work discipline, and the quality of learning. The novelty of this research lies in the discovery of the “Resilient Professionalism” model a model of teacher professionalism that emphasizes resilience and adaptability to changes in curriculum, technology, and educational dynamics. This model is built through the synergy of the spiritual-managerial leadership of the madrasah principal and the collective efficacy of teachers to achieve sustainable quality in Islamic education.

This study aims to (1) identify the effect of using the Direct Instruction learning model on the discipline character values of students in the special sports class at SMA Muhammadiyah Wonosobo, (2) identify the effect of using the Inquiry Learning model on the discipline character values of students in the special sports class at SMA Muhammadiyah Wonosobo,  (3) identify the effect of using the Project-Based Learning model on the discipline character values of students in the special sports class at SMA Muhammadiyah Wonosobo, and (4) determine the most effective learning model among Direct Instruction, Inquiry Learning, and Project-Based Learning in improving the discipline character values of students in the special sports class at SMA Muhammadiyah Wonosobo. This research is an experimental study using a quantitative method with a pre-experimental design, namely the one-group pretest–posttest design. In this design, a single group is given a pretest (O), followed by a treatment (X), and then a posttest. The effect of the treatment can be identified more accurately by comparing the pretest and posttest scores. The stages of the One-Group Pretest–Posttest Design include determining the sample, conducting a pretest to measure students’ initial conditions, administering the treatment, and finally conducting a posttest to identify the results of the treatment. The results of the analysis indicate that all three learning models have a positive effect on improving students’ discipline. The improvement is reflected in the overall mean score, which increased from 114.03 (pretest) to 117.99 (posttest). The improvement scores for each learning model are as follows: Direct Instruction showed a 4% increase by improving compliance through structured learning; Inquiry Learning encouraged independence and self-control through discovery processes with a 3% increase; while Project-Based Learning resulted in a 4% increase in discipline. Thus, it can be concluded that all learning models contribute to the development of discipline character values. These findings provide practical implications for physical education teachers in selecting character-based learning models that are more appropriate.

Learning media is a tool that can be used to help students learn better and more efficiently. The media used in SMP Negeri 23 Pekanbaru is a teacher-centered picture/poster media so that students quickly get bored, and because of the limited media from the school. Most students prefer learning that involves them directly such as the element of games. The learning models used are discovery, PBL, and lecture models, and student learning activities are still lacking or less active in science learning. The purpose of this study is to develop learning media in the form of a cooperative-based snakes and ladders game with the Teams Games Tournament (TGT) type which aims to train student learning activities. The research method used is Research and Development (R&D) by implementing the ADDIE model which consists of five stages, namely Analyze, Design, Development, Implement, and Evaluation. Based on the validation results obtained, media experts were 94% with very feasible criteria, material experts were 92% with very feasible criteria, teachers gave a practicality assessment of 95% with very practical criteria, and students' responses were 85% with very interested criteria. This shows that the snakes and ladders media based on Teams Games Tournament (TGT) is very reasonable, very practical to use, and very interesting for students during the learning process. The results of observations on all student learning activities showed that 79% got a good interpretation.

This study aims to: (1) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the mathematical concept comprehension and self-efficacy of 10th-grade students at SMA Negeri 3 Tarakan; (2) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the mathematical concept comprehension of 10th-grade students at SMA Negeri 3 Tarakan; (3) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the self-efficacy of 10th-grade students at SMA Negeri 3 Tarakan. The research population included all tenth-grade students of SMA Negeri 3 Tarakan in the 2024/2025 academic year. The research sample consisted of two classes selected randomly: one experimental class receiving discovery learning with an aptitude treatment interaction strategy and one control class receiving conventional learning. The research instruments consisted of a test measuring mathematical concept understanding on trigonometry material and a self-efficacy questionnaire. The data obtained were tested for prerequisites through normality and homogeneity tests before being analyzed using inferential statistical tests in the form of an independent samples t-test with the assistance of SPSS software version 26.0. The research results show that the implementation of the discovery learning model with the aptitude-treatment interaction strategy has a significant impact on students' mathematical concept understanding and self-efficacy simultaneously, with a significance value of 0.006 < 0.05. Partially, this learning model has a significant effect on students' mathematical concept understanding, with a significance value of 0.018 < 0.05. However, the effect of the discovery learning model with the aptitude-treatment interaction strategy on students' self-efficacy is not statistically significant, as indicated by a significance value of 0.089 > 0.05, even though there is a tendency for increased self-efficacy among students participating in the experimental class learning. Nevertheless, the influence of the discovery learning model with the aptitude treatment interaction strategy on students' self-efficacy is not statistically significant in partial terms, although there is a tendency for an increase in self-efficacy among students participating in the experimental class. These findings suggest that the discovery learning model with the aptitude treatment interaction strategy is effective in improving students' understanding of mathematical concepts in trigonometry material and has the potential to support the development of self-efficacy in mathematics learning.
