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

The purpose of this research is to determine the influence of the Problem Based Learning model assisted by Google Site Web on students' critical thinking skills on temperature, heat and expansion materials. The type of research used is Quasi Experiment with a Non-equivalent Control Group Design. The sample was taken using the Purposive Sampling technique, so that 65 students of SMP N 2 Payakumbuh were selected for grades VII 9 and VII 10. Data collection is carried out by giving pretest and posttest questions. Based on the data obtained, the tests used are the t-test for pretest and posttest. The t-test in the pretest obtained a tcount value = 3.68 > a ttable of 2.00 which means that there is a significant difference so that Ha is accepted. Meanwhile, in the t-posttest test, the tcount value = 2.29 > ttable 2.00 which means that there is a significant difference in the average of the experimental and control classes. So, based on the results obtained from the mean difference test, it was found that there was a significant difference between the average of the experimental and control classes before and after being given treatment. When we get different research results, to see the effect can be seen from the improvement of the learning outcomes of the two sample classes. Therefore, the N-gain test is used. The results of the hypothesis calculation used are the U test or the Man Whitney test because the data obtained on the N-gain is abnormal but homogeneous. The result of the u test was obtained Zhitung = -1.54 < Ztabel = - 0.73. Referring to the criteria of the u test which states that if the Zhitung < Ztabel then H0 is rejected. So in conclusion, there is an effect of significantly improving student learning outcomes between control and experimental classes. Keywords: PBL, Google, Site, Critical, Thinking.

Abstract

The learning objectives more effectively by using science teaching materials. These materials become more insightful when they incorporate and build upon local wisdom. One way to integrate science is by using a webbed model. Therefore, this study aims to produce a valid and practical webbed type Integrated Science module based on local wisdom with the Pupuik Sarunai theme. This type of research was Research and Development (R&D). This research used the ADDIE development model which had stages of analysis, design, development, implementation and evaluation. However, due to the limited time and cost of research only conducted up to the stage of development (development) and for implementation and evaluation was not conducted yet. This study used an instrument consisting of a validity test and a practicality questionnaire. The data obtained from the results of the study were calculated using Moment Kappa (k) to analyze the results of the validity and practicality tests of the Integrated Science module. The results of the research that has been done indicate that the practicum module developed has a validity test result of 0.87 with a very valid category. The results of the practicality test of the practicum module by the teacher were very practical with the results of 0.87 and the results of the student practicality test were included in the practical category with the results of 0.77. Therefore, it can be concluded that the webbed type Integrated Science module based on local wisdom with the Pupuik Sarunai theme is valid and practical.

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

Teaching materials, as one of the essential components in the learning process, must evolve in line with rapid technological advancements. Therefore, E-module teaching materials need to be developed to enhance students’ understanding and learning outcomes. This study employed Research and Development (R&D) with the 4D model (Define, Design, Develop, and Disseminate) to develop a Problem-Based Learning (PBL)-based E-module integrated with Socio-Scientific Issues (SSI) on ecology and biodiversity topics for junior high school students. The research instruments included teacher interview sheets, student needs analysis questionnaires, validity questionnaires, and practicality questionnaires. Data were analyzed for validity and practicality. The findings revealed that the developed PBL-based E-module integrated with SSI achieved a very valid category, with an average validity score of 90%, and a very practical category, with an average practicality score of 96%. It can be concluded that the PBL-based science learning E-module integrated with SSI on ecology and biodiversity meets the criteria of validity and practicality, making it suitable for use by teachers and students.
