Abstract

Penelitian ini bertujuan untuk mengembangkan modul pembelajaran berbasis Problem-Based Learning (PBL) pada materi laju reaksi bagi siswa kelas XI SMA/MA. Modul dikembangkan melalui model 4-D, yang terdiri dari tahapan Define, Design, Develop, dan Disseminate. Pada tahap Define, dilakukan analisis kebutuhan dan tujuan pembelajaran. Tahap Design meliputi penyusunan modul dengan komponen utama berupa pengenalan konsep, penyajian masalah, serta panduan eksperimen laboratorium. Tahap Develop mencakup validasi modul oleh dua ahli kimia, yang menilai aspek kelayakan isi, bahasa, dan tampilan visual dengan hasil rata-rata validasi sebesar 90,34%, mengindikasikan modul sangat layak. Pada tahap Disseminate, modul diujicobakan pada siswa untuk mengukur kepraktisan dan efektivitasnya. Hasil penelitian menunjukkan bahwa modul ini praktis digunakan dalam pembelajaran dengan skor kepraktisan 81%. Efektivitas modul dievaluasi melalui tes pretest dan posttest, yang menunjukkan peningkatan rata-rata nilai siswa dari 49,33% menjadi 81%. Peningkatan ini mencerminkan peningkatan signifikan dalam pemahaman materi serta keterampilan berpikir kritis, analitis, dan pemecahan masalah siswa. Dengan demikian, modul berbasis PBL ini dinyatakan efektif untuk diterapkan dalam pembelajaran kimia, khususnya pada materi laju reaksi, dan direkomendasikan untuk dikembangkan lebih lanjut pada topik-topik kimia lainnya. Development of Problem-Based Learning (PBL) Module on Reaction Rate Material  Abstract This study aims to develop a Problem-Based Learning (PBL) instructional module focused on reaction rates for eleventh-grade high school students (SMA/MA). The module was developed using the 4-D model, which comprises the stages of Define, Design, Develop, and Disseminate. In the Define stage, needs analysis and learning objectives were conducted. The Design stage involved the creation of the module, incorporating key components such as concept introduction, problem presentation, and laboratory experiment guidelines. During the Develop stage, the module was validated by two chemistry experts who assessed its content feasibility, language, and visual presentation, yielding an average validation score of 90.34%, indicating high feasibility. In the Disseminate stage, the module was pilot-tested with students to evaluate its practicality and effectiveness. The results demonstrated that the module is practical for instructional use, receiving a practicality score of 81%. The module’s effectiveness was assessed through pretest and posttest evaluations, which showed an average student score improvement from 49.33% to 81%. This increase reflects a significant enhancement in students' understanding of the material as well as their critical thinking, analytical, and problem-solving skills. Consequently, the PBL-based module is deemed effective for implementation in chemistry education, particularly concerning reaction rates, and is recommended for further development in other chemistry topics.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh strategi pembelajaran Context-Rich Problem (CRP) terhadap pemahaman konsep reaksi redoks siswa kelas X di SMA Al-Ma'arif Taklimusshibyan Sangkong. Metode penelitian yang digunakan adalah kuasi-eksperimen dengan desain posttest-only control group, melibatkan 52 siswa yang dibagi menjadi kelompok eksperimen yang menggunakan strategi CRP dan kelompok kontrol yang diajar dengan metode ceramah. Pengumpulan data dilakukan melalui tes pemahaman konsep yang diberikan setelah perlakuan. Hasil penelitian menunjukkan bahwa siswa yang diajar dengan strategi CRP memiliki rata-rata nilai posttest lebih tinggi (79,16) dibandingkan dengan kelompok kontrol (69,87). Selain itu, ketuntasan klasikal pada kelompok eksperimen mencapai 92%, sedangkan pada kelompok kontrol hanya 78%. Uji-t menunjukkan perbedaan yang signifikan antara kedua kelompok dengan nilai p sebesar 0,000 (p < 0,05), yang mengonfirmasi bahwa strategi CRP memiliki dampak positif terhadap pemahaman konsep reaksi redoks siswa. Dengan demikian, strategi CRP efektif dalam meningkatkan pemahaman konsep reaksi redoks dan mendorong partisipasi aktif siswa dalam pembelajaran kimia. The Effect of Context-Rich Problem (CRP) Learning Strategy on Students' Conceptual Understanding of Redox Reactions  Abstract This study aims to examine the effect of the Context-Rich Problem (CRP) learning strategy on students' conceptual understanding of redox reactions in Grade X at SMA Al-Ma'arif Taklimusshibyan Sangkong. A quasi-experimental method with a posttest-only control group design was used, involving 52 students divided into an experimental group using the CRP strategy and a control group taught through lectures. The study’s data collection employed a conceptual understanding test administered post-intervention. Results indicate that students taught with the CRP strategy achieved a higher average posttest score (79.16) compared to the control group (69.87). Furthermore, the experimental group attained a classical mastery level of 92%, exceeding the control group's 78%. A t-test analysis revealed a significant difference between the groups, with a p-value of 0.000 (p < 0.05), confirming the positive impact of the CRP strategy on students' conceptual understanding of redox reactions. Thus, CRP is effective in enhancing students' understanding of redox reaction concepts and fostering active participation in chemistry learning.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh model Problem-Based Learning (PBL) terhadap kemampuan generik sains dan pemahaman konsep siswa pada materi reaksi reduksi-oksidasi. Metode kuasi-eksperimen dengan desain pretest-posttest control group digunakan pada 53 siswa kelas X di SMA Islam Al-Azhar NW Kayangan, yang dibagi secara acak menjadi kelompok eksperimen (n=25) dan kontrol (n=28). Hasil penelitian menunjukkan bahwa kelompok eksperimen yang diajarkan dengan PBL mengalami peningkatan signifikan dalam kemampuan generik sains, terutama pada indikator bahasa simbolik (nilai rata-rata posttest 75,00) dan inferensi logika (29,00), dengan signifikansi 0,000. Peningkatan pemahaman konsep siswa juga signifikan pada kelompok eksperimen, dengan rata-rata posttest 70,60 dibandingkan kelompok kontrol yang hanya mencapai 46,00 (signifikansi 0,003). Temuan ini menunjukkan bahwa PBL lebih efektif daripada metode konvensional dalam meningkatkan kemampuan generik sains dan pemahaman konsep siswa dalam materi kimia yang kompleks. Penerapan PBL dalam pembelajaran kimia di sekolah disarankan untuk meningkatkan kualitas pemahaman siswa terhadap konsep-konsep abstrak. The Effect of Problem-Based Learning Model on Students’ Generic Science Skills and Conceptual Understanding  Abstract This study aimed to examine the effect of the Problem-Based Learning (PBL) model on students' generic science skills and conceptual understanding of redox reactions. A quasi-experimental method with a pretest-posttest control group design was employed with 53 tenth-grade students from SMA Islam Al-Azhar NW Kayangan, who were randomly assigned into an experimental group (n=25) and a control group (n=28). The findings revealed that the experimental group taught using PBL showed a significant increase in generic science skills, particularly in symbolic language (posttest mean score of 75.00) and logical inference (29.00), with a significance level of 0.000. Conceptual understanding also improved significantly in the experimental group, with a posttest mean score of 70.60, compared to 46.00 in the control group (significance level of 0.003). These results indicate that PBL is more effective than conventional methods in enhancing both generic science skills and conceptual understanding in complex chemistry topics. The study recommends PBL application in chemistry education to deepen students' understanding of abstract concepts.
