Abstract

This research was motivated by the low student learning outcomes during the science learning process caused by the application of learning models that are not varied, causing students to be less enthusiastic and tending to be passive in learning. This study aimed the effect of Children Learning In Science (CLIS) learning model on science learning outcomes of seventh-grade students of SMP Negeri 13 Padang. The type of research used is quasi experiment with posttest only control group design. The sampling technique is purposive sampling. Based on the results of the student response questionnaire to the CLIS model, a percentage of 87% was obtained in the very good category. Based on the average of the experimental class of 73.5 and the control class of 66. Then, continued with the hypothesis test using the t-test, the tcount> ttable value is 3.85 > 2,00 with a sample of 32 students and α=0.05. The results of the hypothesis are H0 rejected and Ha accepted, meaning that there is a significant effect of the application of the Children Learning In Science (CLIS) learning model on the learning outcomes in class VII SMPN 13 Padang.

Abstract

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.

Abstract

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.

Abstract

This study aims to determine the effect of the Creative Problem-Solving (CPS) learning model on the creative thinking skills of eighth-grade students at SMP Negeri 29 Padang. The research employed a quasi-experimental design with a nonequivalent control group. The study was conducted at SMP Negeri 29 Padang, West Sumatra. The sample was selected using purposive sampling, consisting of 34 students from class VIII-9 as the experimental group and 34 students from class VIII-6 as the control group. The instrument used was a test in the form of essay questions. The results showed that the hypothesis was accepted, as the significance value obtained was less than 0.05. These findings suggest that the implementation of the Creative Problem-Solving learning model is an effective strategy for enhancing students’ creative thinking skills. Therefore, it is recommended that teachers integrate the CPS model into classroom instruction to encourage students to be more active, innovative, and capable of solving problems creatively.

Abstract

This study examined the effect of implementing the Problem-Based Learning (PBL) model assisted by Wordwall on the learning achievement of seventh-grade students at SMPN 12 Padang. The research employed a quasi-experimental design with a non-equivalent control group. The population consisted of all seventh-grade students, while the sample was selected purposively, comprising classes VII-5 and VII-7. The experimental group received instruction through the PBL model integrated with Wordwall activities, whereas the control group was taught using conventional methods. Data were collected using multiple-choice tests administered as pretests and posttests, and analyzed using Microsoft Excel. The results revealed a significant difference in the average scores between the experimental and control groups. The t-test analysis yielded a calculated t-value of 2.3027, which exceeded the critical t-value of 1.9964, indicating the rejection of the null hypothesis (H₀) and acceptance of the alternative hypothesis (Hₐ). These findings suggest that the use of the PBL model assisted by Wordwall significantly enhances students’ learning achievement in seventh-grade science at SMPN 12 Padang.

Abstract

Learning activities in natural science subject have considerable potential for development, particularly in creating a more engaging and communicative classroom environment through active student participation. The implementation of the Problem-Based Learning (PBL) model is expected to enhance students’ communication skills, as it encourages collaborative investigations, problem-solving, and discussion of results. This study aimed to examine the effect of the PBL model on students’ communication skills in learning the Earth and Solar System topic. The research was conducted at SMPN 1 Kec. Guguak over five weeks, from May to June 2024, involving 53 students selected through purposive sampling. The sample consisted of 26 students in the experimental class and 27 in the control class. A quasi-experimental method with a Post-test Only Control Group Design was employed. The indicators of communication skills assessed included oral communication, written communication, and interpersonal communication. Data were collected using a communication test comprising six essay questions that had been validated and tested for reliability. Data analysis was carried out using descriptive statistics and inferential statistics through the Mann-Whitney test with SPSS version 25. The results of the Mann-Whitney test showed a significance value of 0.044 (p < 0.05), indicating that H0 was rejected and Ha was accepted. Therefore, it can be concluded that the PBL model has a significant effect on students’ communication skills.

Abstract

This study aims to examine the effect of implementing the Case-Based Learning (CBL) model on the problem-solving skills of eighth-grade students at SMP Negeri 30 Padang. The research population consisted of all eighth-grade students at the school. A quasi-experimental design with a non-equivalent control group was employed. The sample was selected using a purposive sampling technique, resulting in classes VIII B and VIII D being chosen as the experimental and control groups, respectively. The experimental class was taught using the CBL model, while the control class received instruction through a conventional learning model. Data were collected through pretest and posttest in the form of essay-type questions administered to both groups. The data were analyzed using the tʹ-test. The results indicated a significant difference in the mean scores between students taught using the CBL model and those taught using the conventional model. The tʹ-test results showed that tcount > ttable (8.544 > 2.009), leading to the acceptance of the alternative hypothesis and rejection of the null hypothesis. It can be concluded that the CBL model had a significant positive effect on the problem-solving skills of eighth-grade students at SMP Negeri 30 Padang.
