This study aims to analyze students' mental models on the concept of chemical bonds using a two-tier mental model diagnostic test. A test with the first tier asking the content and the second tier asking the reasons for the answers at the first tier. The test used has been developed and declared valid with a degree of reliability 0.751. This research is qualitative research with a case study design. Students' mental models are categorized into complete mental models, partial mental models, mental models with misconceptions, and mental models with inconsistencies. In the concept of chemical bonds found 17, 9, 15, and 59% of students with complete, partial, misconceptions, and inconsistencies in mental models respectively. Most students have misconceptions by stating that ionic bonds are formed through atomization and the formation of bonding electrons by reason of the sharing of electrons in ionic crystals. In addition, students understand that the process of forming covalent bonds in oxygen and fluorine occurs because of the attraction between atoms which is greater than the repulsion between bonded atoms. Among the inconsistent concepts found are students explaining the phenomenon of solubility, boiling point, and melting point based on the concept of the electron cloud.

Reaction rate is still considered difficult by students because it contains abstract concepts and mathematical equations, so students' mental models are not complete. To connect the three levels of representation in the process of addressing chemical problems, learning has to employ mental models as a whole. Therefore, this study aims to obtain students' mental models regarding the influence of reactants properties on reaction rates. This research uses a qualitative descriptive method with the Mental Model Diagnostic Test-Interview About Event (MMDT-IAE) instrument. Based on the research results, there are two types of mental models, namely Partial Understanding (PU) and Partial Understanding with Certain Misconceptions (PU/SM). The effect of surface area on reaction rate, students 1, 2, 3, 4, 6, and 7 answered correctly but could not connect the three levels of representation, while student 5 could not explain the relationship between effective collisions and reaction rate. The influence of structure on reaction rates, students 1, 2, 3, 4, and 7 can answer structure, reactivity and collision theory, while student 5 cannot explain collision theory. Students 1, 4, and 7 can answer all the probing questions but cannot connect the three levels to the influence of ionization energy on the reaction rate. The conclusion of this research is that students' mental models regarding the influence of reactant properties are not complete and there are students who experience misconceptions. The implications of this research are as a basis for teachers to design appropriate learning strategies.Keywords: Mental model; MMDT-IAE; Reaction rate; Three level of representation

Academic self-efficacy is a critical psychological construct consistently linked to student success. However, the extensive body of research is fragmented, necessitating a systematic synthesis to understand the key factors, outcomes, and underlying mechanisms associated with student’s self-efficacy. The purpose of this systematic literature review is to synthesize and evaluate the current evidence on the effect of self-efficacy on academic achievement and learning engagement. Following the PRISMA guidelines, a comprehensive search was conducted across Science Direct database. The review synthesized findings from 25 articles, focusing on empirical studies that examined the antecedents and consequences of self-efficacy in relation to academic outcomes. The findings reveal that self-efficacy serves as a significant predictor of academic achievement and learning engagement. Results indicate that students with high self-efficacy demonstrate greater persistence, set more ambitious goals, and exhibit higher resilience in challenging subjects. The discussion highlights that this relationship is mediated by both social support and cognitive engagement strategies. In conclusion, developing self-efficacy is essential for optimizing educational outcomes

The aim of this study is to identify how the POE learning integrated into D-GBL can construct student’s mental models on temperature effect on reaction rate and the game design is created. This research is a part of the Research and Development (R&D) with Borg and Gall model. This study is focused on the third stage. The study began with collecting information, planning product, and prototype development. For product design, the study created mission and sub-missions to represent the POE steps, which are predicting, observing, and explaining. The information was collected from various literature reviews on D-GBL and mental model. For product design, mission and sub-missions were created to represent POE steps. Next, the prototype was developed in the form of a game design document. Students must answer various questions to complete these missions and sub-missions. If the answers are given incorrect, the game restart from the beginning of that mission. Therefore, D-GBL integrated in the POE model can construct students' mental models.

Pendekatan deep learning digunakan oleh Kementerian Pendidikan Dasar dan Menengah untuk meningkatkan proses dan mutu pembelajaran. Prinsip pendekatan deep learning terdiri dari berkesadaran (mindful), bermakna (meaningful), dan menggembirakan (joyful). Pendekatan deep learning dianggap baru oleh guru-guru kimia di kota Bekasi dan menyebabkan kesulitan dalam implementasi pembelajaran di kelas. Pembelajaran di kelas hanya berfokus pada level makroskopik dan simbolik, yang mengakibatkan siswa kesulitan dalam memvisualisasikan kimia di level submikroskopik. Tujuan pengabdian adalah untuk melatih guru kimia kota Bekasi dalam mengimplementasikan strategi pembelajaran berbasis intertekstual dengan pendekatan deep learning. Metode yang digunakan adalah pelatihan yang dilakukan di SMAN 6 Kota Bekasi. Hasil dari pelatihan adalah sebanyak 95% guru merasa sangat puas dengan materi dan narasumber pelatihan, sebanyak 75% guru sangat memahami konsep pembelajaran kimia berbasis intertekstual, sebanyak 77,5% guru sangat memahami pendekatan deep learning dalam pembelajaran kimia, dan sebanyak 92,5% guru merasa sangat puas setelah mengikuti pelatihan.
