Abstract

This study aims to see the improvement of conceptual understanding and identification of students self-confidence by applying the Problem Based Learning (PBL) learning model to chemical bonding material. This type of research is quantitative with a pre-experimental design using the one group pretest-posttest step. The sample of this research was 36 students of Class X MIA 1 at SMA Negeri 13 Pekanbaru. Data collection techniques were using questionnaires and questionnaires. Quantitative descriptive data analysis technique was by calculating the percentage value of students' concept understanding. The results of data analysis showed that there was an increase in understanding of the concept of chemical bonds from 37.28 (pretest) to 81.39 (posttest), which was an increase of 44.11. The results of the analysis using the paired sample t-test with a significance value of 0.000 < 0.05. The results of the identification of students self-confidence obtained 81.94 with a very good category.

Abstract

This research addresses the need for effective teaching materials in natural materials chemistry courses, specifically focusing on secondary metabolite compounds derived from endophytic bacteria of laban plants. The main objective is to develop a valid e-pocket book that serves as an enrichment resource for lecturers and students. This study used a research and development approach using the 4-D model, which includes the stages of defining, designing, developing, and disseminating. However, this research was limited to the development stage. The E-Pocket Book was assessed for validity through various aspects, including content feasibility, presentation, grammar, graphics, appearance, and software utilisation. Validation involved feedback from material and media validators, as well as responses from chemistry education lecturers and students. Results showed that the E-Pocket Book achieved a highly valid category with an overall average score of 98.785% across the six assessment aspects. Feedback from chemistry education lecturers showed excellent criteria, with scores of 87.50% for content appropriateness and for usefulness, and 91.67% for ease of use. Similarly, student feedback reflected high satisfaction, with scores of 86.67% for ease of use, 85% for benefits of use and 83.09% for attractiveness of presentation. In conclusion, the developed E-Pocket Book was validated as a practical and effective teaching material for secondary metabolite compounds, demonstrating its potential to enhance the learning experience in natural materials chemistry courses. This study highlights the importance of incorporating user feedback in the development process to ensure materials meet educational needs and preferences

Abstract

This research aims to determine the effectiveness of chemistry laboratory literacy levels by developing an e-EncyLab using 3D Pageflip Professional. This study employs a quantitative research methodology. The participants were 10th-grade students. Data was collected using a set of 12 essay questions designed to assess chemistry laboratory literacy, available in the e-EncyLab. Increasing laboratory literacy level abilities can be determined using the N-gain test. The results of this research showed an increase in N-Gain of 0.68 in the medium category. The effect of using e-EncyLab in increasing chemistry laboratory literacy is shown by the results of the paired sample test, which shows sig 0.000 < sig 0.05, which means there is a significant difference in the level of chemistry laboratory literacy of students in the control class and the experimental class that uses e-EncyLab. The use of e-EncyLab is effective in increasing students' chemistry laboratory literacy.

Abstract

Misconceptions in learning chemical equilibrium remain a persistent challenge that can hinder students' understanding and academic confidence. Despite various efforts to improve conceptual mastery, many students still harbor incorrect notions that affect their learning outcomes and self-belief. To address this issue, this study explores the relationship between students' misconceptions and their self-efficacy regarding chemical equilibrium concepts. The research employed a research and development approach using the ADDIE model, utilizing an Android-based five-tier multiple choice test as a diagnostic instrument. A random sampling technique was applied to select three senior high schools in Pekanbaru: SMAN 8 Pekanbaru, SMAN Olahraga Provinsi Riau, and SMAN 3 Pekanbaru. A correlation test was conducted to determine the presence, direction, and strength of the relationship between students' misconceptions and their self-efficacy. The results revealed a positive correlation between the two variables across schools with high, medium, and low academic profiles

Abstract

This paper discusses the effect of an interactive engagement strategy using Quizizz on students' critical thinking skills on chemical bonding material. This research used a quasi-experimental design because not all factors influencing learning can be controlled. This research was conducted in two experimental classes, the experimental and the control classes. The experimental class was given treatment in the form of an interactive engagement strategy using Quizlet. And the control class was given conventional model treatment. The sampling technique in this research is purposive sampling, which considers the homogeneity of the sample (class). The experimental and control class samples were 29 students from class X at MAN 1 Pekanbaru. The research results show that the ability to infer, namely making conclusions and presenting problems, dominates with the highest percentage value of 85%. On the other hand, analytical skills, which involve finding causes, assessing impacts, and predicting further impacts, recorded the lowest percentage with 50%. Overall, the average percentages for the four indicators reached 67.5%, which is in the good category. The Independent Sample T-Test statistical test, with a significance value (sig) of 0.000, revealed a significant difference in scientific literacy abilities between experimental and control class students. Of the N-Gain analysis, it is known that the average gain score for critical thinking skills in the experimental class (0.50 or 50%) is in the medium category, while the control class only reached 0.30 (30%), which is included in the low category. This shows a more significant increase in learning outcomes for critical thinking skills in the experimental class compared to the control class.

Abstract

Pemilihan model pembelajaran yang tepat dapat menciptakan suasana belajar yang menyenangkan, yang pada akhirnya dapat menghasilkan prestasi belajar yang baik. Model ini memberikan kesempatan kepada peserta didik untuk mengembangkan pengetahuan mereka sendiri serta mengkomunikasikan ide-ide yang telah mereka pelajari melalui diskusi. Peserta didik mengalami kesulitan dalam memahami konsep materi pembelajaran hal ini menyebabkan hasil belajar menjadi rendah. Salah satu aspek hasil belajar yaitu aspek kognitif. Dalam meningkatkan aspek kognitif membantu peserta didik dalam membangun pengetahuan mereka maka pemahaman peserta didik akan sesuai dengan konsep yang benar. Penelitian ini bertujuan untuk mengetahui tingkat kognitif peserta didik setelah penerapan model pembelajaran POE2WE pada pokok bahasan laju reaksi. Penelitian ini menggunakan penelitian eksperimen dengan metode Quasi eksperimen di mana variabel-variabelnya dianalisis dengan membagi subjek ke dalam dua kelompok: kelompok eksperimen dan kelompok kontrol. Subjek penelitian adalah peserta didik kelas XI.3 dan XI.4 SMA Negeri 2 Tambang tahun ajaran 2024/2025 yang berjumlah 89 orang. Berdasarkan hasil penelitian disimpulkan bahwa penerapan model pembelajaran POE2WE dapat meningkatkan hasil belajar kognitif pada materi laju reaksi. Hasil analisis tahap akhir diperoleh rata-rata hasil belajar pada ranah kognitif kelas eksperimen dan kelas kontrol adalah 86,41 dan 75,6 dengan hasil belajar kognitif pada kategori sangat baik
