Abstract

The rapid development of information technology in the digital era must be utilized optimally to improve the quality of learning Physics. The use of virtual laboratories can replace real laboratories as a means of proving theories, laws, and concepts of physics. This study aims to analyze the use of virtual media in the form of PhET simulation as an alternative to real experiments (reels). This type of research is an experiment) by providing treatment in the form of learning. The research subjects were Quality University students divided into 2 classes, namely the experimental class (2A23), totaling 32 students, and the control class (2B22), consisting of 33 students. Data collection techniques used research instruments, namely learning achievement tests and observations. Hypothesis testing in this study used a 2-way analysis of variance (Two Way Anova) on the univariance General Linear Model (GLM) with the SPSS 21 program. From the results of the study, there was a significant difference between the learning outcomes of Science Physics and the level of student activity in class compared to classes taught using a conventional method, so there is a significant interaction between learning methods and activity levels on student learning outcomes in Science Physics. It was concluded that using virtual laboratory learning methods based on PhET simulation, especially on fluid material, affected student learning outcomes.

Abstract

This study aims to analyze the effectiveness of the Problem-Based Learning (PBL) model integrated with Guided Inquiry in improving students' chemistry learning outcomes on the topic of solutions among 11th-grade senior high school students. The research was motivated by the low conceptual understanding and critical thinking skills among students, often attributed to the predominance of conventional teaching methods. A quantitative approach with a quasi-experimental design, specifically the non-equivalent control group design, was employed. The participants included two randomly selected classes from SMA Negeri 2 Pematang Siantar: one experimental class (n = 34) and one control class (n = 34). A learning achievement test was used as the main instrument, comprising pre-test and post-test items. The results showed that both groups experienced learning gains; however, the experimental class demonstrated a significantly higher gain score of 0.71 (high category), while the control class achieved a gain score of 0.58 (moderate category). An independent samples t-test revealed a significant difference between the two groups (p = 0.000 < 0.05), indicating that the integrated PBL and guided inquiry model had a substantial impact on students' learning outcomes. These findings suggest that the implementation of PBL integrated with guided inquiry is an effective pedagogical approach to enhance conceptual mastery and should be considered in the teaching of complex chemistry topics.

Abstract

This study aims to determine the effect of the Problem Based Learning learning model on student learning outcomes in the learning of Natural and Social Sciences (IPAS) in class VI SD Negeri 064034 Medan Learning Year 2024/2025. This study used a quantitative method with a pretest-posttest experimental design in one group, involving 28 students as samples. Data collection was carried out through learning outcome tests and student participation questionnaires that had been tested for validity and reliability. The pretest results showed the average value of student learning outcomes of 57.7 with a low category, while the posttest results increased to 77.43 with a high category. The Pearson correlation test produced a coefficient of 0.850 with a significance of 0.000, which indicates a strong positive relationship between the application of the PBL model and student learning outcomes. Furthermore, the results of hypothesis testing using the t-test obtained a tcount ≥ ttable value of 5.957 ≥ 2.048, which means that there is a significant influence between the use of the Problem Based Learning learning model on student learning outcomes. Thus, the research hypothesis which states that there is a significant effect of the Problem Based Learning learning model on student learning outcomes.

Abstract

This research is a quantitative research method with an experimental research type. This research aims to determine the effect of the Problem Based Learning model assisted by Question Card media on students' critical thinking skills in the IPAS subject of grade IV at SD Negeri 066049 Medan Helvetia. The research subjects consisted of 34 fourth-grade students from the same school. The instruments used in this study were questionnaires and multiple-choice test items. The students' critical thinking skills showed an average pretest score of 57.06, and after the treatment using the Problem Based Learning model, the average posttest score increased to 82.35. The results indicate a strong influence of variable X on variable Y, with a correlation coefficient of 0.699. Given that the r_table value is 0.339, the alternative hypothesis (Ha) is accepted. Furthermore, hypothesis testing showed that the t_count was 24,070 while the t_table was 1.691, proving that the hypothesis is significant, thus the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted. This demonstrates that the Problem Based Learning model assisted by Question Card media has a significant effect on students' critical thinking skills.

Abstract

This study aims to determine the effect of the Talking stick learning model based on Wordwall on student learning outcomes in the Science lesson on the material "My dear earth, my poor earth" V SD Negeri 004 Balam Sempurna in the 2024/2025 Academic Year. The research method used is an experimental method with a quantitative research type. To obtain data, a test instrument of 35 questions and a questionnaire of 27 items are required. The number of research samples was 23 students using a purposive sampling technique. To determine the initial abilities of students, the researcher conducted a Pretest with an average score of 69.56 which was included in the sufficient category. The results of the Pretest have increased from the results of the Posttest given previously with an average score reaching 87.39 with a very good category. It can be said that the level of success of student learning outcomes using the Talking stick model based on Wordwall has increased and has an effect with a strong category as evidenced by the results of the correlation coefficient test calculation obtained the results of r_count ≥〖 r〗_table with results of 0.755 ≥ 0.413. Next, hypothesis testing compares the value of t_count ≥ t_table. The value of t_count = 11.943 while t_table = 1.714 is obtained. Because t_count ≥ t_table (11.943 ≥ 1.714) then Ha is accepted and Ho is rejected. Through the t-test, it can be concluded that there is a significant positive influence between the Talking stick learning model based on Wordwall (X) on student learning outcomes (Y).

Abstract

This study aims to determine the effect of the CORE (Connecting, Organizing, Reflecting, Extending) learning model assisted by visual media on student learning outcomes in the IPAS subject for Grade IV at SD Negeri 060954 Medan Marelan. The research employed a One Group Pretest-Posttest Design with tests and questionnaires as data collection instruments. A total of 26 students participated as the research sample. The CORE model was implemented through structured steps that guided students to connect prior knowledge with new concepts, organize ideas, reflect on information, and deepen understanding through assignments. The results showed a significant improvement in the students’ average scores from 46.92 (pretest) to 85.34 (posttest), with 23 out of 26 students achieving mastery learning. The t-test analysis yielded tcount = 2.156 > ttable = 2.064, and the correlation coefficient was r = 0.403 > rtable = 0.388, indicating a moderate and significant relationship between the CORE model implementation and student learning outcomes. Furthermore, questionnaire responses revealed that students enjoyed the use of visual media, as it made learning more engaging, concrete, and easier to understand. These findings support cognitive learning theory and previous research showing that the CORE model enhances student engagement and conceptual understanding. It can be concluded that the CORE learning model assisted by visual media significantly improves student learning outcomes in IPAS, while fostering collaborative and meaningful learning experiences.
