This research was driven by the observation that many students still lack a strong understanding of the subject matter, leading to below-average performance. Another factor that causes low student learning outcomes is the lack of variety in learning models applied by teachers so that learning becomes uninteresting. For this reason, various learning models are needed, such as the application of the guided discovery learning model The results of previous research stated that this model can improve student learning outcomes. This study aims to determine the effect of the application of the guided discovery learning model on students’ learning outcomes. This type of research is a quasi experiment with a nonequivalent control group design research design. The sampling technique uses the purposive sampling technique. The sample consists of one experimental class by applying the guided discovery learning model and one control class with a conventional model. This study conducted a statistical analysis using Microsoft Excel. The result shows that there is an improvement in students’ learning outcomes in the control class in the low category, while the increase in students’ learning outcomes in the experimental class is in the medium category.

Cognitive ability is one of the essential aspects emphasized in the Merdeka Curriculum. One of the ways to enhance students’ cognitive ability is by applying the Project Based Learning-STEM (PjBL-STEM) model. This research was motivated by observations conducted on Grade VIII students at SMPN 21 Padang during the 2024/2025 academic year. The observations revealed that although the teacher implemented the PjBL-STEM model, its application was not fully optimal. The purpose of this study was to determine the effect of the PjBL-STEM learning model on students’ cognitive ability on the topic of vibration and wave. This study employed a quasi-experimental method with a posttest control group design. Purposive sampling was used to select the samples. Grade VIII students taught using the PjBL-STEM model served as the experimental group, while another Grade VIII class taught using conventional discovery learning served as the control group. The research instrument was an objective written test. The collected data were analyzed using normality, homogeneity, and hypothesis testing. The t-test results showed a t-count of 10.283 and a t-table value of 2.036, where tcount ≥ ttable. Therefore, H0 was rejected and H1 was accepted, indicating a significant effect of the PjBL-STEM model on students’ cognitive ability in junior high school.

Low students learning outcomes are often attributed to conventional teacher-centered instructional methods, which render students passive and hinder their ability to comprehend and apply scientific concepts effectively. This study aims to evaluate the effect of the Interactive Conceptual Instruction (ICI) learning model on the academic performance of seventh-grade students at SMPN 34 Padang, specifically in the topic of substance classification and changes. This research employed a quasi-experimental design using a posttest-only control group approach. The sample consists of two classes, an experimental group that received instruction using the ICI model and a control group that followed conventional methods. Data were analyzed statistically using Microsoft Excel. The results indicate that the average posttest score of the experimental group (77) was higher than that of the control group (65). A t-test analysis yielded a tcount of 5.303, which exceeds the critical ttable of 1.998, indicating a statistically significant difference between the two groups. The implementation of the ICI model was rated positively, with an effectiveness score of 98%, and 94% of students responded favorably to the learning model. In conclusion, the study demonstrates that the application of the ICI model has a significant positive impact on students' learning outcomes in the topic of substance classification and changes.
