HIV/AIDS is a global health issue that significantly impacts adolescents, a vulnerable group prone to risky behaviors such as unprotected sexual intercourse. The lack of knowledge is a key factor contributing to the increased risk of transmission. Therefore, effective health education interventions are essential to address this problem, with one promising approach being health promotion through audiovisual media. This study aims to assess the impact of audiovisual media on improving HIV/AIDS knowledge among 11th-grade students at SMA PGRI 2 Banjarmasin. The study used a quasi-experimental design with a one-group pretest–posttest approach. The entire population of 112 students was selected using a total sampling technique. The data collection tool was a questionnaire that was tested for validity and reliability. The data were analyzed using the Wilcoxon test, as the data were not normally distributed. Prior to the intervention, most students (85.7%) had low levels of knowledge about HIV/AIDS. Following the intervention, all students (100%) demonstrated a significant increase in knowledge, reaching a high level. The Wilcoxon test yielded a p-value of 0.001 (p<0.05), indicating a statistically significant effect. These findings suggest that audiovisual media is a highly effective method for improving adolescents’ knowledge about HIV/AIDS. It serves as both an engaging and preventive educational strategy, making it an important tool in promoting awareness and reducing the risk of HIV/AIDS transmission among youth.

This study aims to improve student learning outcomes and engagement through the implementation of the Teaching at the Right Level (TaRL) approach combined with the Problem Based Learning (PBL) model. The TaRL approach focuses on teaching that is appropriate to each student's ability level, while PBL encourages students to actively solve relevant problems, so that it is expected to improve student engagement and learning outcomes. This study was conducted in the form of classroom action research (CAR) consisting of two cycles. Each cycle includes the planning, implementation, observation, and reflection stages. In the first cycle, the results of student learning completion reached 64%. After reflection and improvement in the first cycle, it was continued with the second cycle which showed an increase in student learning completion to 78%. There was a difference in increase of 14% between the first and second cycles. The results of this study indicate that the implementation of the TaRL approach combined with the PBL model can effectively improve student learning outcomes and engagement. The increase in learning completion from the first cycle to the second cycle illustrates that this approach and model are able to accommodate differences in student abilities and facilitate more effective and interesting learning. Thus, the TaRL approach and the PBL model can be used as effective learning strategies to improve the quality of education in the classroom.

This study aims to determine whether the discovery learning approach for teaching mathematics has an effect on students' learning outcomes. This study is quantitative descriptive research with a pre-experiment, one-group pretest-posttest research design. The research subjects consisted of 31 students from class IXA at junior high school 36 Semarang. The students took a pretest before the implementation of the discovery learning model, and then a posttest was given after the implementation to measure the enhancement of students' learning outcomes. Pretest and Posttest findings revealed an increase in the average scores, which were 47.41 and 80.90, respectively, and the N-Gain test results showed a score of 0.61 in the moderate category. The study's findings shed light on the usefulness of the discovery learning approach in increasing the learning outcomes of class IXA students at junior high school 36 Semarang, particularly in the field of geometry transformation. From the results of the pretest, it was found that 31 students were in the low category. After learning with the discovery learning model, a posttest was carried out with the results of 7 students who were in the low category, 17 students in the medium category, and 7 students in the high category. There were significant changes in the participants' pretest and posttest scores, validating the efficacy of discovery learning strategies. Students who received instruction using the discovery learning model, in particular, had considerably higher posttest results as compared to their pretest scores. This demonstrates a significant increase in their comprehension and application of geometry transformation ideas following participation in the discovery learning technique. Through the discovery learning approach, teachers play a critical role in promoting student-centered learning. While the discovery learning model has been shown to be helpful in improving student learning outcomes, it is critical to investigate other instructional strategies and the use of educational technologies in future research and teaching practices. Additional study should be conducted to explore the usefulness of instructional technology and to establish best practices for its integration in order to improve student accomplishment in the digital era.
