Abstract

The principles of chemistry learning emphasize that students study chemical concept in a structure and detailed manner. Until now, chemistry lessons are still a big challenge for teachers, because students often experience difficulties when learning chemical concept such as the concept of stoichiometry. This study aims to determine the level of concept understanding and the percentage of students' concept understanding on stoichiometry material using a five tier diagnostic test. The method used in this research is descriptive qualitative. The results showed: (1) the average level of students' concept understanding is classified in the category of lack of knowledge (LK); (2) the average percentage of students who understand the concept (SC) is 13.0% and the sub-concept with the highest percentage of understanding the concept (SC) is Relative Molecular Mass which is 33.0%. Of the 15 questions tested, question number 1 has the highest percentage of understanding the concept (SC) of 33.0%, while for the other 14 questions the average student is classified in the category of lack of knowledge (LK). It can be concluded that students' concept understanding on stoichiometry material is still classified as very low criteria.

Abstract

This study analyzed the profiles of students’ concept mastery and scientific literacy on the topic of reduction-oxidation (redox) reactions in three senior high schools in North Gorontalo, Indonesia. A descriptive qualitative approach was employed, involving written tests and interviews with 12th-grade students at SMAN 1, SMAN 3, and SMAN 6 North Gorontalo. The test instruments were designed based on the revised Bloom’s Taxonomy cognitive levels (C1–C6) and Programme for International Student Assessment (PISA) scientific literacy dimensions (context, content, competence, attitude). Results indicate that students have moderate overall concept mastery, with highest performance on lower-order cognitive skills remembering (C1) and understanding (C2) but substantially lower performance on higher-order skills such as applying (C3), analyzing (C4), evaluating (C5), and creating (C6). In terms of scientific literacy, students performed best in the content knowledge dimension, while showing weaknesses in scientific attitudes. Specifically, around 59% of students could recall basic facts (C1), but only ~35% could tackle creation-based tasks (C6). Likewise, over 54% demonstrated understanding of scientific content, yet less than 47% exhibited strong scientific competencies or attitudes. These findings suggest that current teaching practices heavily emphasize rote learning of content, leading to decent factual knowledge but insufficient higher-order thinking and lack of engagement with science in real-life contexts. The study highlights the need for instructional innovations such as inquiry-based, problem-based, and context-oriented learning to strengthen students’ conceptual understanding at all cognitive levels and to foster scientific skills and attitudes.

Abstract

This study aimed to assess the critical thinking abilities of 12th grade students on the topic of atomic structure using a complex multiple-choice test instrument based on the Rasch Model. The research found that the instrument was valid and reliable in measuring students' critical thinking skills. The majority of students (75%) demonstrated adequate critical thinking abilities, while 25% faced difficulties, particularly with items measuring inference and explanation. Students performed better on questions related to interpretation and evaluation but struggled with questions that required them to draw conclusions and explain more complex scientific phenomena. These results indicated that while students had a solid understanding of the basic concepts of atomic structure, they needed more practice to improve their higher-order critical thinking skills. Small gender differences were observed, with male students performing slightly better on analysis and inference items, although these differences were not significant. Overall, the findings suggest that while students had a strong foundational knowledge, there is a need for reinforcement through more challenging questions and deeper critical thinking exercises to further develop their critical thinking abilities.

Abstract

This study aimed to develop a differentiated teaching module to enhance students' scientific argumentation skills on chemical bonding material. The method used was Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate). Validation results from experts showed that the developed differentiated teaching module was highly valid (92% and 94%), very practical (100% and 97%), and effective, with more than 80% of students achieving the minimum competency standard (KKM) and an average score of 88. The improvement in scientific argumentation skills was reflected in the average pre-test score of 64, which increased to 80 in the post-test. Specifically, the indicators of scientific argumentation showed improvement: claims increased from 62.9% to 75.4%, data from 66.3% to 84%, warrants from 67.8% to 82.1%, and backings from 68.4% to 79.4%. The increase in scientific argumentation scores from pre-test to post-test indicates that the developed teaching module was effective in helping students hone their argumentative skills. However, the ability to formulate claims and backings still requires reinforcement, as they demand a more complex understanding. Nevertheless, this improvement suggests that the differentiated teaching module created and implemented can strengthen students' scientific argumentation skills in understanding chemical bonding material, making it recommended for broader application, especially in science education.

Abstract

Tidak adanya minat, komitmen, dan pemahaman dari berbagai pihak terkait seperti guru, orang tua, dan peserta didik sering menyebabkan sekolah tidak berkarakter. Banyak sekolah menemukan bahwa mereka tidak memiliki pendekatan yang sesuai dengan nilai-nilai karakter yang diinginkan, yang menyebabkan ketidakjelasan dalam penerapannya. Tujuan pada penelitian ini adalah untuk merumuskan dan mengidetifikasi bagaimana strategi menciptakan sekolah yang berkarakter di Indonesia. Hal ini sangat penting karena sistem Pendidikan yang di terapkan di Indonesia belum mampu secara efektif dalam menanamkan nilai-nilai karakter pada peserta didik. Teknik analisis data yang digunakan dalam penelitian ini meliputi pengumpulan data dengan cara menganalisis dan mengidentifikasi konten dari berbagai sumber yang berhubungan dengan “Menciptakan sekolah berkarakter.” Proses pengumpulan data yang dilakukan melalui Teknik dokumentasi, yang mencakup membaca text reading, dengan cara mengkaji, mempelajari dan mencatat literatur yang relevan. Hasil dari penelitian ini menujukkan bahwa menciptakan sekolah berkarakter harus menjadi bagian intregral dari kurikulum sekolah. Sekolah sangat wajib dan perlu menerapkan Pendidikan berkarakter yang bermoral secara praktis dan mengembangkan figur teladan di kalangan guru dan peserta didik. Selain itu, penting juga melibatkan masyarakat dan keluarga dalam proses menciptakan sekolah berkarakter, sehingga Pendidikan yang berdasarkan karakter dapat berjalan efektif dan berkelanjutan. Dengan kata lain Pendidikan karakter yang ada disekolah mampu membangun peserta didik yang berkualitas dan dapat mengurangi perilaku negatif terhadap peserta didik.

Abstract

Effective geography education requires instructional media capable of visualizing spatial phenomena in a realistic and interactive manner. Google Earth, a digital mapping application based on satellite imagery and geospatial data, offers an innovative approach to address this need. This study aims to examineimplementation and advantages of Google Earth as a contextual learning medium in geography education through a systematic literature review. The analysis reveals that Google Earth significantly enhances students’ comprehension of key geographical concepts, including absolute and relative location, spatial distribution, spatial interaction, and regional dynamics, through 3D visualizations and geospatial data exploration. Furthermore, its integration supports project-based and inquiry-based learning models aligned with the Merdeka Curriculum. However, several challenges hinder its implementation, such as limited technological infrastructure, low digital literacy among educators and learners, and various technical issues. To fully leverage the potential of Google Earth in geography instruction, strategic implementation planning, teacher training, and institutional support are essential.
