Abstract

This research aims to provide a comprehensive overview of the current state of research on atomic structure misconceptions, as well as identifying the best strategies to overcome them. Systematic Literature Review (SLR) approach to identify, study, evaluate, and interpret research results related to misconceptions in atomic structure material at the high school level. This approach was chosen because it is able to provide a systematic and comprehensive overview of various relevant research, so that it can find patterns, trends and research gaps that exist over a certain period of time. The analysis focuses on the forms of misconceptions, causal factors, and learning strategies to overcome these misconceptions which are based on the results of literacy studies, especially those originating from 10 selected articles (which were selected based on SLR-based research methods). The research results show that there are misconceptions in the concept of atomic structure starting from the concept of the atomic model, the quantum mechanical model, the Aufbau principle, the Hund principle, the Pauli exclusion principle, to the sub-atomic concept of the composition of an atom. The results of this study provide important insight for teachers and curriculum developers regarding steps that can be taken to reduce misconceptions.

Abstract

This study aims to understand the influence of emotions, especially anxiety and motivation, on the chemistry learning process. This study uses a qualitative approach with a phenomenological method, involving seven students from various levels of education. Students of the class of 2024 experience academic anxiety related to their choice of major, inability to attend lectures, and uncertainty about the future. Meanwhile, final year students face anxiety about completing their studies and the challenges of entering the workforce. The results of the study show that excessive anxiety has an impact on low student engagement in learning, especially in class discussions and problem solving. Students with high anxiety tend to rely on passive learning methods and have difficulty understanding chemistry concepts in depth. In contrast, high motivation plays a role in increasing academic engagement, building better conceptual understanding, and encouraging students to be more active in finding solutions to learning difficulties. These findings emphasize the importance of learning strategies that can reduce academic anxiety and increase student motivation. A more interactive learning approach and emotional support from the academic environment have the potential to create a more effective and productive learning experience. Thus, this study provides insights for educational institutions to design more adaptive strategies in improving the quality of chemistry learning.

Abstract

This study aims to analyze the effectiveness of scaffolding-based learning with multiple representations in improving students' understanding of atomic structure and electron configuration. The subjects of the study consisted of 42 students from the 3T area, who were divided into an experimental group and a control group. The experimental group received learning with scaffolding based on multiple representations, while the control group received conventional learning. The results showed that there was a significant increase in conceptual understanding in the experimental group, with an average pretest score of 45.2 and a posttest score of 78.5. In addition, the scaffolding technique based on multiple representations was proven effective in reducing students' misconceptions about atomic structure and electron configuration, as well as increasing their learning motivation. Therefore, this learning strategy is recommended to be widely applied in chemistry learning, especially for students in the 3T area who have limited access to learning resources and low numeracy skills.

Abstract

The STEM Center for Teaching and Learning at Parahyangan Catholic University, in collaboration with Ruang Bergerak, organized a community outreach program as part of its Tridharma commitment. The program included seminars and hands-on training for science teachers from the MGMP (Subject Teachers Forum) in Salatiga. The goal was to introduce project-based learning (PBL) methods using a STEM (Science, Technology, Engineering, and Mathematics) approach within the context of smart agriculture. This initiative aimed to help teachers foster essential 21st-century skills—such as problem-solving, critical thinking, and collaboration—that had noticeably declined during the pandemic. This program was designed to support teachers in implementing integrated, project-based learning that not only crosses disciplinary boundaries but also ties directly to measurable learning outcomes. Teachers were encouraged to connect the projects to real-world contexts, making assessments more meaningful and relevant to each subject area. Additionally, the smart agriculture project served as a practical application of P5 (Proyek Penguatan Profil Pelajar Pancasila) under Indonesia’s Merdeka Curriculum. Teachers were given the flexibility to adapt the prototype projects for further development in their own schools, aligning with each school’s unique goals and agreements. Over the course of two days, participating teachers learned how to design and execute contextual, problem-based STEM projects. They gained hands-on experience with technologies like Arduino and agricultural sensors. The program consisted of two main phases, the first involved expert-led workshops, and the second focused on collaborative project design based on local agricultural challenges. Despite the limited time, the program successfully fostered collaboration among teachers and expanded their understanding of how integrated, STEM-based learning can support both academic goals and character development through P5.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi tingkat kecemasan matematika serta mengidentifikasi faktor-faktor penyebabnya pada mahasiswa baru program studi Pendidikan Guru Sekolah Dasar (PGSD) di Kampus Unesa 5. Penelitian ini menggunakan pendekatan kuantitatif-deskriptif dengan teknik total sampling, yang melibatkan seluruh mahasiswa baru PGSD tahun akademik 2024/2025 sebanyak 157 orang. Data dikumpulkan melalui angket skala Likert lima poin yang mencakup empat dimensi kecemasan (mood, motorik, kognitif, dan somatik), serta satu pertanyaan terbuka untuk mendalami persepsi mahasiswa. Hasil penelitian menunjukkan bahwa mayoritas mahasiswa (69,4%) berada pada kategori kecemasan matematika sedang, sementara 18,5% menunjukkan kecemasan tinggi. Determinan utama yang memengaruhi kecemasan meliputi pengalaman belajar negatif di masa lalu, ketidakpahaman konsep dasar, gaya mengajar dosen yang monoton, rendahnya kepercayaan diri, serta tekanan sosial dan akademik. Temuan ini menguatkan hipotesis bahwa kecemasan matematika di kalangan mahasiswa calon guru bersifat kompleks dan multidimensional, serta membutuhkan intervensi pedagogis yang empatik dan kontekstual.
