2025-05-12T23:56:52+00:00

Grade X students of SMA Negeri 2 Bontang experienced problems of low biology learning outcomes and lack of collaboration skills due to conventional teacher-centered learning. This study aimed to determine the effect of implementing the CTL (Contextual Teaching and Learning) model on students' collaboration skills and learning outcomes. The CTL model emphasizes active student involvement in the learning process, connecting material with real-life contexts, and encouraging collaboration and group discussion. This study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. Sampling was carried out by purposive sampling, with class X5 as the experimental class implementing the CTL model and class X6 as the control class using conventional methods. Data analysis was carried out using the N-Gain test and the Independent Sample t Test. The results showed that the experimental class had an N-Gain value of 0.72 (high category) while the control class had 0.59 (moderate category). The t test showed a significance value of 0.000 <0.05 for collaboration skills and learning outcomes. These results indicate a significant difference between the experimental class and the control class after the CTL model was implemented. Based on these results, it can be concluded that the application of the CTL model has a positive and significant effect on improving the collaboration skills and learning outcomes of class X students of SMA Negeri 2 Bontang in biology subjects.

This study aimed to determine the effect of the project based learning model with digital microsite media on the critical thinking skills of class VII students at SMP Negeri 1 Samarinda. This study used a quasi-experimental design method with a non-equivalent control group design. The sample consisted of 20 students, with the experimental class using the project based learning model and the control class using the conventional model. The results showed that in the experimental class, the average pre-test and post-test scores increased from 60.35 to 86.95 with an N-Gain of 0.67. While in the control class, the average pre-test and post-test scores increased from 59.7 to 71.65 with an N-Gain of 0.29. The T-test results show that the significance value is 0.000 <0.0005 with t count> t table, so it can be concluded that the project based learning model with digital microsite media has a significant effect on the critical thinking skills of class VII students of SMP Negeri 1 Samarinda on the material of classification of living things.

Latar belakang penelitian adalah rendahnya kemampuan mengambil keputusan pada peserta didik kelas VIIA SMP Negeri 11 Jember Tahun Ajaran 2024/2025. Tujuan penelitian ini yaitu untuk meningkatkan kemampuan mengambil keputusan peserta didik kelas VIIA pada materi Ekologi dan Keanekaragaman Hayati Indonesia dengan menggunakan model pembelajaran Problem Based Learning (PBL). Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK). Desain penelitian meenggunkan model penelitian Kemmis dan Mc Taggart dengan empat tahap yaitu perencanaan, pelaksanaan, pengamatan dan refleksi. Penelitian ini dilaksanakan sebanyak dua siklus, pad tiap siklus terdiri dari dua pertemuan. Teknik pengumpulan data berupa pretest, posttest, Lembar Kerja Peserta Didik, dan lembar observasi pembelajaram. Teknik analisis data menggunakan Uji N-Gain Score. Hasil penelitian menunjukkan terdapat peningkatan kemampuan mengambil keputusan peserta didik berdasarkan Uji N-Gain Score pada siklus I sebesar 0,31 dengan kategori sedang dan siklus II sebesar 0,70 dengan kategori sedang. Kesimpulan dari penelitian ini yaitu model pembelajaran Problem Based Learning dapat meningkatkan kemampuan mengambil keputusan peserta didik kelas VIIA.

The Effectiveness of Student Worksheet with Problem Based Learning and Ethnoscience to Improve Critical Thinking Skills on Chemical Bonding Material

2025-05-28T07:52:41+00:00

Learning chemistry through the merdeka curriculum prioritize on enhancing 21^st century skills include students' critical thinking skills. Due to a number of critical thinking skill constraints, students find out the difficulties to comprehend theory-based in chemistry materials, such as chemical bonding materials. By problem-based learning that integrates ethnoscience content can make learning more meaningful is a way to train and enhance critical thinking skills. This research conducted in terms to quantify the effectiveness of Problem Based Learning and ethnoscience-based student worksheet on chemical bonding material to enhance the critical thinking skills of XI grade senior high school students. The research method used are descriptive quantitative and qualitative of One Group Pretest-Posttest Design. With 36 students of class XI-8 in SMAN 16 Surabaya as the subject, the worksheet stated effective according to the increasingly of N-gain value with an average of 0.7206 that is in the high category. As much as 26 students include into the high category, 8 fall into the medium category, and 2 fall into the low category. Therefore, the finding suggest that student worksheet with Problem Based Learning and ethnoscience-based student worksheet on chemical bonding materials can significantly improve students’ critical thinking abilities.

Development of Greenhouse Effect Teaching Tool to Develop Science Process Skills in Class VII Middle School Students on the Theme of Global Warming

2025-05-28T07:38:11+00:00

The purpose of this research is to create a greenhouse effect teaching tool in science learning on the theme
of global warming to foster Science Process Skills (PPP) in students. The development model used is a 4-
D development model which consists of four stages: define, design, develop, and disseminate. Product
validation was carried out by science education experts and practitioner experts who showed the level of
product validity with a value of 86.18% included in the "excellent" category. The implementation of the use
of greenhouse effect props was carried out by grade VII students at one of the junior high schools in Serang
City. The data of the student response questionnaire showed that the teaching aids were able to grow PPP
with a score of 80.37% with the "very good" category. The results of this study prove that the use of teaching
aids in science learning on the theme of global warming can help grow students' PPP through practicum
activities.

Hubungan Keterampilan Public Speaking Dengan Kemampuan Berpendapat Peserta Didik Pada Materi Keanekaragaman Hayati Di Kelas X MAN 1 Samarinda Plus Keterampilan Dan Riset

2025-05-14T06:18:26+00:00

This study investigates the relationship between students' public speaking abilities and their capacity to articulate opinions on biodiversity topics in Class X at MAN 1 Samarinda (specializing in skills and research). Employing a quantitative approach with a correlational design, the researcher selected participants using purposive sampling from classes X-A and X-C. Data were analyzed using the Spearman correlation test, which produced a p-value of 0.001 indicating statistical significance (p < 0.05). The findings reveal a strong, positive, and significant relationship between public speaking proficiency and students’ ability to express views on biodiversity.
