Abstract

The effect of the integrated interactive Education for Sustainable Development (ESD) module on learning interest and creative thinking skills of class VII students at SMPN 23 Pekanbaru was the focus of this study. One of the learning resources that is particularly suitable for the 21st century is interactive modules. These modules serve as detailed learning packages designed to help students achieve their learning objectives. The Education for Sustainable Development (ESD) approach used in this study aims to not only increase students' interest and readiness to learn but also enhance their creative thinking skills. The purpose of this research was to examine and analyze the effect of the integrated interactive ESD module on learning interest and creative thinking skills, and to describe the correlation between learning interest and creative thinking skills in students. The study employed a quasi-experimental design combined with correlation analysis, using instruments such as a learning interest questionnaire and a creative thinking skills test. The findings of the study indicated that the integrated interactive ESD module had a significant effect on both the learning interest and the creative thinking skills of students. Furthermore, there was a positive correlation between learning interest and creative thinking skills, suggesting that enhancing students' engagement in the learning process through interactive modules can foster the development of their creative thinking abilities. These results highlight the importance of interactive learning resources in supporting student achievement in the 21st century

Abstract

The main objective of this study was to determine the extent to which students' critical thinking skills can be improved through the implementation of a guided inquiry learning model based on Education for Sustainable Development (ESD). This study used a quasi-experimental approach with a post-test only control group design. The study population consisted of 5 classes with a total of 190 students. From this population, the researcher took a sample of 68 students through a simple random sampling technique. The sample was then divided into two groups, namely 34 students for the experimental class and 34 students for the control class. The research instrument was a critical thinking skills test consisting of 20 objective, reasoned questions. The research data were analyzed using a t-test. Based on the calculation results, the t-value was 3.792, while the t-table value at a significance level of 0.05 was 2.037. This indicates that Ha is accepted and Ho is rejected. Thus, there is a significant difference between the critical thinking skills of students who participated in learning with a guided inquiry model based on ESD compared to conventional learning. In addition, the improvement in critical thinking skills was also analyzed through the N-Gain calculation. The results showed that the experimental class achieved a 65% improvement, categorized as moderate, while the control class achieved a 59% improvement, also categorized as moderate. These findings indicate that guided inquiry learning integrated with ESD principles provides a more effective way to foster students' critical thinking skills compared to traditional methods. Therefore, ESD-based guided inquiry learning can be an alternative, innovative learning strategy to improve the quality of the learning process in secondary schools.

Abstract

This study aims to determine the application of a mind-mapping Project-Based Learning (PjBL) model to the human digestive system in improving creative thinking skills and creativity in eighth-grade students at SMP Dakwah Pekanbaru. This study used a quantitative approach with a one-group pretest-posttest pre-experimental design. The subjects consisted of eighth-grade students at SMP Dakwah Pekanbaru. The research instruments included a creative thinking skills test, a product creativity assessment sheet, and learning documentation. Data were analyzed using descriptive statistics, the N-gain test, the Wilcoxon test, and the Spearman correlation test. The results showed an increase in students' creative thinking skills after implementing the mind-mapping-based PjBL model, as indicated by an increase in the average posttest score compared to the pretest and a low to moderate N-gain score. Furthermore, students' product creativity was in the good category and had a significant relationship with their creative thinking skills. Thus, implementing the mind-mapping-based PjBL model is effective in improving students' creative thinking skills and creativity in the human digestive system.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar peserta didik pada materi sistem tata surya, kurangnya variasi media pembelajaran serta kurangnya keterlibatan siswa dalam pembelajaran IPA. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan modul berbasis puzzle terhadap hasil belajar peserta didik kelas VII di SMP Negeri 1 Kampar Kiri. Penelitian menggunakan pendekatan quasi eksperimen dengan desain Posttest Only Control Design. Yang melibatkan sampel kelas VII.A sebagai kelas eksperimen dan VII.B sebagai kelas kontrol yang ditentukan melalui purposive sampling. Instrumen penelitian berupa tes pilihan ganda beralasan untuk mengukur ranah kognitif dan lembar observasi untuk menilai ranah afektif serta psikomotor. Analisis data menunjukkan bahwa terdapat perbedaan signifikan hasil belajar kognitif antara kelas eksperimen dan kontrol dengan nilai signifikansi 0,000 (<0,05). Selain itu, hasil observasi menunjukkan terdapat peningkatan ranah afektif dengan persentase sebesar 88,33% dengan kategori sangat baik dan pada ranah psikomotor sebesar 83,75% dengan kategori baik. Dengan demikian, modul berbasis puzzle berpengaruh signifikan terhadap hasil belajar peserta didik dan dapat menjadi alternatif bahan ajar inovatif dalam pembelajaran IPA.
