Abstract

The study used a pseudo-experimental design with a posttest-only control group design pattern. The population included the entire class VII, and the sample was randomly selected of two equivalent parallel classes, totaling 22 students each. The experimental class received the discovery learning treatment, while the control class used conventional methods. The research instrument is in the form of learning outcome tests in the form of objectives and essays that have been tested for validity and reliability. Data were analyzed through normality test, homogeneity test, and t-test of two independent samples at a significance level of 0.05. The results showed significant differences between the two groups. The average posttest score of the experimental class was 80.68 higher than the control class of 72.72. The analysis of the t-test yielded a t_hitung value of 2.74 greater than t_tabel 2.01, which means that the null hypothesis was rejected. The frequency distribution in the experimental class also showed a concentration of scores in the high category, while the control class was more dominant in the medium category. These findings confirm that discovery learning not only improves cognitive learning outcomes, but also encourages students' active engagement, motivation, and critical thinking skills. This study concludes that the implementation of discovery learning is effective in improving science learning outcomes in the classification of living things. Implicitly, teachers are advised to integrate this approach as an alternative to student-centered science learning strategies.

Abstract

The internship program is designed to introduce students to the practical application of the theories and knowledge they have acquired during their studies in a real work environment. This activity was conducted at SMP Swasta Galih Agung, an educational institution under the Darularafah Raya Islamic Boarding School Foundation, which aims to develop pious, skilled, and technologically literate students with strong physical and intellectual abilities. At the beginning of the odd semester of the 2023–2024 academic year, the number of female students enrolled was 470, but by the end of the semester, it had decreased to 455, representing a 0.96% decline. The purpose of this study is to perform a ranking analysis for selecting the best teacher based on expertise and teaching performance. The research employs the SMARTER (Simple Multi-Attribute Rating Technique Exploiting Ranks) method, combined with ROC (Rank Order Centroid) weighting and sensitivity analysis to measure the accuracy of ranking results. The findings show that the teacher with code T10 achieved the highest score of 0.521, followed by T7, T1, T2, T5, T11, T12, T8, T4, T9, T6, and T3, with the lowest score being 0.310. The lowest sensitivity value of 0 indicates the most optimal weighting result. The decision support system designed using questionnaires and Excel simplifies data input and assists the principal in making objective and efficient decisions.

Abstract

The development of digital media and innovative learning models in Junior High School Science education reflects a sustained commitment to meeting the demands of 21st-century skills and improving the quality of science instruction. A comprehensive literature review (2019–2024) reveals the dominance of the Research and Development (R&D) approach, which consistently yields highly valid, practical, and effective digital resources, such as Augmented Reality (AR), Android-based applications, and interactive educational games. These digital tools are synergistically integrated with modern instructional models, including Problem-Based Learning (PBL), Inquiry-Based Learning (IBL), and Predict-Observe-Explain (POE), which are proven effective in increasing student engagement, enhancing cognitive outcomes, and honing essential competencies such as Science Process Skills (SPS) and Higher-Order Thinking Skills (HOTS). Ultimately, this integration contributes significantly to overcoming learning difficulties in complex and abstract Science topics (e.g., the human digestive system) while also effectively addressing contemporary educational challenges, fostering meaningful learning experiences, and supporting long-term academic success for students.

Abstract

    This study aims to describe students' ability to solve open-ended problems based on aspects of fluency, flexibility, and novelty. This type of research is qualitative. The subject taking technique in this study was purposive. The instruments that the researchers used were open-ended tests and interview guides. The research subjects were 3 students of SMP Negeri 2 Puring class VIII for the 2021/2022 academic year who had high abilities. The data collection technique used is in the form of test sheets in the form of circle questions, field notes, interviews, and documentation. The data analysis technique used is the analytical technique from Miles & Huberman which includes three activities, namely data reduction, data presentation, and drawing conclusions. The results of this study indicate that students with high abilities have a level of creative thinking 3 (creative). Students with high abilities in solving circle problems can fulfill two of the three indicators that the researcher used. The indicators are fluency and flexibility. Fluency indicators are shown by students being able to answer questions fluently and correctly. The indicator of flexibility (flexibility) is shown by students being able to answer questions with more than one way of solving.

Abstract

The type of research used is a quasi-quantitative experiment. This experimental research uses a quasi-experimental research design with nonequivalent control group design. This study aims to determine the effect of the Learning Starts With a Question learning model on student learning outcomes in fifth grade science learning at SD Negeri Bontokamase. From the test results, the Pretest value is 0.055 > 0.05 and the Post-test value is 0.073 > 0.05. From these tests, it can be concluded that the Pretest value is greater than 0.05 and the Post-test value is greater than 0.05. The homogeneity test results obtained Sig value α = 0.575, this means that the Sig value is greater than α (0.575 > 0.05) so that it can be concluded that the two groups are homogeneous. the hypothesis results obtained Sig (2.Tailed) = 0.000 meaning that H0 was rejected because Sig (2.Tailed) < α or (0.000 < 0.05). H1 is accepted because Sig (Tailed) > α or (0.575 > 0.05). In the T test analysis, Sig < table or (0.575 < 1.697). ). Based on the results of the study it can be concluded that there is a significant influence between learning taught using the Learning Starts With a Question model and conventional learning on science learning in fifth grade students of SD Negeri Bontokamase.

Abstract

This study aims to determine the use of audio-visual media in Problem-Based Learning to improve student learning outcomes in tenth grade SMA Negeri 2 Tondano using classroom action research as the research methodology. (1) Planning, (2) Action, (3) Observation, and (4) Reflection are the four major phases of a cycle. In data analysis, the1percentage of completed student1learning outcomes is utilized. The research result was derived from student learning outcomes using two cycles; in cycle I, the1percentage of classical completion was 44.44 percent and in cycle II, it was 55.55 percent. It became a reference for the subsequent cycle's follow-up. The classical percentage of completeness for cycle II was then 92.59 percent complete and 7.40 percent incomplete. This demonstrated that it followed the research indicator in a conventional manner. Therefore, it is unnecessary to follow the subsequent cycle. This study concludes that using problem-based learning audio-visual as a learning medium for virus materials is crucial for improving student learning outcomes among students in1class X at SMA Negeri 21Tondano.
